Engineering Changes in Product Design - A Review

Science.gov (United States)

Karthik, K.; Janardhan Reddy, K., Dr

2016-09-01

Changes are fundamental to product development. Engineering changes are unavoidable and can arise at any phase of the product life cycle. The consideration of market requirements, customer/user feedbacks, manufacturing constraints, design innovations etc., turning them into viable products can be accomplished when product change is managed properly. In the early design cycle, informal changes are accepted. However, changes become formal when its complexity and cost increases, and as product matures. To maximize the market shares, manufacturers have to effectively and efficiently manage engineering changes by means of Configuration Control. The paper gives a broad overview about ‘Engineering Change Management’ (ECM) through configuration management and its implications in product design. The aim is to give an idea and understanding about the engineering changes in product design scenario to the new researchers. This paper elaborates the significant aspect of managing the engineering changes and the importance of ECM in a product life cycle.

Full Text Available Product development is less than 20-30 years old and a relatively new area of research compared to the other classic academic disciplines. Integrated product development is a philosophy that systematically employs the teaming of functional disciplines to integrate and concurrently apple all the necessary processes to produce an effective and efficient product that satisfies customer needs. Product development might also be understood as a multidisciplinary field of research. The disciplines directly participating in product development include engineering design, innovation, manufacturing, marketing and management. A background contribution is also generated by disciplines such as psychology, social sciences and information technology. This article is an overview that introduces this philosophy to textile product development.

Design of chemicals-based products is broadly classified into those that are process centered and those that are product centered. In this article, the designs of both classes of products are reviewed from a process systems point of view; developments related to the design of the chemical product, its corresponding process, and its integration are highlighted. Although significant advances have been made in the development of systematic model-based techniques for process design (also for optimization, operation, and control), much work is needed to reach the same level for product design. Timeline diagrams illustrating key contributions in product design, process design, and integrated product-process design are presented. The search for novel, innovative, and sustainable solutions must be matched by consideration of issues related to the multidisciplinary nature of problems, the lack of data needed for model development, solution strategies that incorporate multiscale options, and reliability versus predictive power. The need for an integrated model-experiment-based design approach is discussed together with benefits of employing a systematic computer-aided framework with built-in design templates.

THE PRODUCT DESIGN PROCESS USING STYLISTIC SURFACES

Directory of Open Access Journals (Sweden)

Arkadiusz Gita

2017-06-01

Full Text Available The increasing consumer requirements for the way what everyday use products look like, forces manufacturers to put more emphasis on product design. Constructors, apart from the functional aspects of the parts created, are forced to pay attention to the aesthetic aspects. Software for designing A-class surfaces is very helpful in this case. Extensive quality analysis modules facilitate the work and allow getting models with specific visual features. The authors present a design process of the product using stylistic surfaces based on the front panel of the moped casing. In addition, methods of analysis of the design surface and product technology are presented.

Product design pattern based on big data-driven scenario

Directory of Open Access Journals (Sweden)

Conggang Yu

2016-07-01

Full Text Available This article discusses about new product design patterns in the big data era, gives designer a new rational thinking way, and is a new way to understand the design of the product. Based on the key criteria of the product design process, category, element, and product are used to input the data, which comprises concrete data and abstract data as an enlargement of the criteria of product design process for the establishment of a big data-driven product design pattern’s model. Moreover, an experiment and a product design case are conducted to verify the feasibility of the new pattern. Ultimately, we will conclude that the data-driven product design has two patterns: one is the concrete data supporting the product design, namely “product–data–product” pattern, and the second is based on the value of the abstract data for product design, namely “data–product–data” pattern. Through the data, users are involving themselves in the design development process. Data and product form a huge network, and data plays a role of connection or node. So the essence of the design is to find a new connection based on element, and to find a new node based on category.

Mandenius, Carl-Fredrik; Björkman, Mats

2010-05-01

Traditionally, biotechnology design has focused on the manufacture of chemicals and biologics. Still, a majority of biotechnology products that appear on the market today is the result of mechanical-electric (mechatronic) construction. For these, the biological components play decisive roles in the design solution; the biological entities are either integral parts of the design, or are transformed by the mechatronic system. This article explains how the development and production engineering design principles used for typical mechanical products can be adapted to the demands of biotechnology products, and how electronics, mechanics and biology can be integrated more successfully. We discuss three emerging areas of biotechnology in which mechatronic design principles can apply: stem cell manufacture, artificial organs, and bioreactors. Copyright 2010 Elsevier Ltd.

Enhancing product robustness in reliability-based design optimization

International Nuclear Information System (INIS)

Zhuang, Xiaotian; Pan, Rong; Du, Xiaoping

2015-01-01

Different types of uncertainties need to be addressed in a product design optimization process. In this paper, the uncertainties in both product design variables and environmental noise variables are considered. The reliability-based design optimization (RBDO) is integrated with robust product design (RPD) to concurrently reduce the production cost and the long-term operation cost, including quality loss, in the process of product design. This problem leads to a multi-objective optimization with probabilistic constraints. In addition, the model uncertainties associated with a surrogate model that is derived from numerical computation methods, such as finite element analysis, is addressed. A hierarchical experimental design approach, augmented by a sequential sampling strategy, is proposed to construct the response surface of product performance function for finding optimal design solutions. The proposed method is demonstrated through an engineering example. - Highlights: • A unifying framework for integrating RBDO and RPD is proposed. • Implicit product performance function is considered. • The design problem is solved by sequential optimization and reliability assessment. • A sequential sampling technique is developed for improving design optimization. • The comparison with traditional RBDO is provided

Applying environmental product design to biomedical products research.

Science.gov (United States)

Messelbeck, J; Sutherland, L

2000-12-01

The principal themes for the Biomedical Research and the Environment Conference Committee on Environmental Economics in Biomedical Research include the following: healthcare delivery companies and biomedical research organizations, both nonprofit and for-profit, need to improve their environmental performance; suppliers of healthcare products will be called upon to support this need; and improving the environmental profile of healthcare products begins in research and development (R&D). The committee report begins with requirements from regulatory authorities (e.g., U.S. Environmental Protection Agency [EPA], the U.S. Food and Drug Administration), and the healthcare delivery sector). The 1998 American Hospital Association and EPA Memorandum of Understanding to reduce solid waste and mercury from healthcare facilities is emblematic of these requirements. The dominant message from the requirements discussion is to ensure that R&D organizations do not ignore customer, environmental, and regulatory requirements in the early stages of product development. Several representatives from healthcare products manufacturers presented their companies' approaches to meeting these requirements. They reported on efforts to ensure that their R&D processes are sensitive to the environmental consequences from manufacturing, distributing, using, and disposing of healthcare products. These reports describe representatives' awareness of requirements and the unique approaches their R&D organizations have taken to meet these requirements. All representatives reported that their R&D organizations have embraced environmental product design because it avoids the potential of returning products to R&D to improve the environmental profile. Additionally, several reports detailed cost savings, sustainability benefits, and improvements in environmental manufacturing or redesign, and increased customer satisfaction. Many companies in healthcare delivery are working to improve environmental

2017-07-01

Full Text Available With the increasing awareness of sustainability, eco-design has been an important trend in the fashion industry. Many fashion brands such as Nike, Adidas, and The North Face have developed sustainable fashion by incorporating eco-design elements. Eco-design is an important part of sustainable supply chains. In this paper, we conducted a product line analysis of eco-designed products from a famous outdoor sportswear brand, Patagonia. We collected Patagonia’s 2017 Spring Season product line data and analyzed the data through descriptive analysis, factor analysis and correlation analysis. We found that Patagonia mainly uses organic, recycled, and traceable materials in their eco-product line development. We identified that the usage of eco-materials may significantly affect the number of color choices and product weight as well as gender difference, pattern design, product fit and online reviewers’ opinions at Patagonia. We argued that Patagonia should focus on functionality more than aesthetics in eco-design. We discussed how sustainable fashion firms should manage eco-design in the supply chain.

Landwehr Jan R.

2015-11-01

Full Text Available The success stories of design-oriented companies like Apple, Audi or Nike have put design on the agenda in many marketing departments. Consumers cannot elude the effect of aesthetics and therefore design is a major factor for business success. Typically consumers choose the product with the best design, all other aspects being equal. Only when the interplay of product characteristics, brand and design is carefully coordinated can successful products be created. This requires an integrated approach to design, one which is applied right at the beginning of the value chain. Product development, marketing and design need to work in close cooperation, communicate well and frequently, and collect feedback from the market. Superior aesthetics are always important but should be a top priority in cases where efficiency-oriented Asian competitors are able to offer functionally similar products at much lower prices.

Brown, Christopher J; Cheng, James M

2014-05-01

To review the available evidence regarding electronic cigarette (e-cigarette) product characterisation and design features in order to understand their potential impact on individual users and on public health. Systematic literature searches in 10 reference databases were conducted through October 2013. A total of 14 articles and documents and 16 patents were included in this analysis. Numerous disposable and reusable e-cigarette product options exist, representing wide variation in product configuration and component functionality. Common e-cigarette components include an aerosol generator, a flow sensor, a battery and a nicotine-containing solution storage area. e-cigarettes currently include many interchangeable parts, enabling users to modify the character of the delivered aerosol and, therefore, the product's 'effectiveness' as a nicotine delivery product. Materials in e-cigarettes may include metals, rubber and ceramics. Some materials may be aerosolised and have adverse health effects. Several studies have described significant performance variability across and within e-cigarette brands. Patent applications include novel product features designed to influence aerosol properties and e-cigarette efficiency at delivering nicotine. Although e-cigarettes share a basic design, engineering variations and user modifications result in differences in nicotine delivery and potential product risks. e-cigarette aerosols may include harmful and potentially harmful constituents. Battery explosions and the risks of exposure to the e-liquid (especially for children) are also concerns. Additional research will enhance the current understanding of basic e-cigarette design and operation, aerosol production and processing, and functionality. A standardised e-cigarette testing regime should be developed to allow product comparisons.

The marketing implications of affective product design.

Science.gov (United States)

Seva, Rosemary R; Duh, Henry Been-Lirn; Helander, Martin G

2007-11-01

Emotions are compelling human experiences and product designers can take advantage of this by conceptualizing emotion-engendering products that sell well in the market. This study hypothesized that product attributes influence users' emotions and that the relationship is moderated by the adherence of these product attributes to purchase criteria. It was further hypothesized that the emotional experience of the user influences purchase intention. A laboratory study was conducted to validate the hypotheses using mobile phones as test products. Sixty-two participants were asked to assess eight phones from a display of 10 phones and indicate their emotional experiences after assessment. Results suggest that some product attributes can cause intense emotional experience. The attributes relate to the phone's dimensions and the relationship between these dimensions. The study validated the notion of integrating affect in designing products that convey users' personalities.

A Contradiction-Based Approach for Innovative Product Design

Directory of Open Access Journals (Sweden)

Ko Yao-Tsung

2016-01-01

Full Text Available Without creativity in design there is no potential for innovation. This paper investigates the role of contradictions in enhancing creativity in product design. Based on the inventive principles of TRIZ, this paper presents a novel design method by integrating technical and physical contradiction analysis methods into the conceptual design activities of new product development (NPD. Despite the recognized importance of innovative design, there is a lack of the systematic and effective design-thinking process that can covers all conceptual design activities. To address this gap, a sharper and fundamental model of the problem-solving is created for innovative product design based on the contradiction-oriented concept. Eventually, one case study is employed to illustrate the method and the result validates that it can help designers produce more creative outcomes in product design.

This mark enables consumers to quickly identify and choose products that can help protect the environment and are safer for families. When you see the DfE logo on a product it means that the DfE scientific review team has screened each ingredient for potential human health and environmental effects and that-based on currently available information, EPA predictive models, and expert judgment-the product contains only those ingredients that pose the least concern among chemicals in their class. Product manufacturers who become DfE partners, and earn the right to display the DfE logo on recognized products, have invested heavily in research, development and reformulation to ensure that their ingredients and finished product line up on the green end of the health and environmental spectrum while maintaining or improving product performance. EPA's Design for the Environment Program (DfE) has allowed use of their logo on over 2500 products. These products are formulated from the safest possible ingredients and have reduced the use of chemicals of concern by hundreds of millions of pounds.

On-demand microbicide products: design matters.

Science.gov (United States)

Patel, Sravan Kumar; Rohan, Lisa Cencia

2017-12-01

Sexual intercourse (vaginal and anal) is the predominant mode of human immunodeficiency virus (HIV) transmission. Topical microbicides used in an on-demand format (i.e., immediately before or after sex) can be part of an effective tool kit utilized to prevent sexual transmission of HIV. The effectiveness of prevention products is positively correlated with adherence, which is likely to depend on user acceptability of the product. The development of an efficacious and acceptable product is therefore paramount for the success of an on-demand product. Acceptability of on-demand products (e.g., gels, films, and tablets) and their attributes is influenced by a multitude of user-specific factors that span behavioral, lifestyle, socio-economic, and cultural aspects. In addition, physicochemical properties of the drug, anatomical and physiological aspects of anorectal and vaginal compartments, issues relating to large-scale production, and cost can impact product development. These factors together with user preferences determine the design space of an effective, acceptable, and feasible on-demand product. In this review, we summarize the interacting factors that together determine product choice and its target product profile.

A REVIEW: A MODEL of CULTURAL ASPECTS for SUSTAINABLE PRODUCT DESIGN

Directory of Open Access Journals (Sweden)

Ihwan Ghazali,

2012-04-01

Full Text Available Product design stages are important to consider critically in production. Generally, product design that shall be created by designer, should consider what the customer wants and needs. Nowadays issues, product design does not only consider the “wants and needs” of user, but also how the design can be created by embedding sustainability aspects in the product. Culture is also one of the important aspects which need to be considered in product design as culture affects the way users respond to the product. This paper aims to develop a new model for design development, in which the aspects of culture are incorporated into sustainable product design. By reviewing the existing literature, the authors attempt to identify the gaps of the existing papers, which illustrate how culture affects sustainable product design. Recent papers have only shown that culture influences product design, but they do not explore sustainability and the culture aspects in product design. Due to these gaps, it is therefore important to create a model which will assist designers to elicit sustainable product design based on cultural aspects. In summary, designers need to reflect on the “wants and needs” of users. The framework presented in this paper can be integrated into designers’ and companies’ decision-making during product design development.

Alex Lobos

2013-03-01

Full Text Available Current models for Information and Communication Technology (ICT products encourage frequent product replacement with newer versions that offer only minor incremental improvements. This pattern, named planned obsolescence, diminishes user experience and shortens product lifespan. This paper presents the conceptual basis for a two-part integrated approach to combating planned obsolescence in ICT devices. First, design for emotional attachment, which creates products that users enjoy, value, and use for longer. Second, technological adaptability, which anticipates product upgrades and repairs as new technologies emerge. A model interdisciplinary design course in industrial design and sustainability, also described herein, trains students to apply this approach to create innovative ICT products with smaller environmental footprints.

A Systematic Optimization Design Method for Complex Mechatronic Products Design and Development

Directory of Open Access Journals (Sweden)

Jie Jiang

2018-01-01

Full Text Available Designing a complex mechatronic product involves multiple design variables, objectives, constraints, and evaluation criteria as well as their nonlinearly coupled relationships. The design space can be very big consisting of many functional design parameters, structural design parameters, and behavioral design (or running performances parameters. Given a big design space and inexplicit relations among them, how to design a product optimally in an optimization design process is a challenging research problem. In this paper, we propose a systematic optimization design method based on design space reduction and surrogate modelling techniques. This method firstly identifies key design parameters from a very big design space to reduce the design space, secondly uses the identified key design parameters to establish a system surrogate model based on data-driven modelling principles for optimization design, and thirdly utilizes the multiobjective optimization techniques to achieve an optimal design of a product in the reduced design space. This method has been tested with a high-speed train design. With comparison to others, the research results show that this method is practical and useful for optimally designing complex mechatronic products.

2005-01-01

In 1985, MINT built the only radiopharmaceutical production facility in Malaysia. The facility was designed based on IAEA (International Atomic Energy Agency) standard guidelines which provide radiation safety to the staff and the surrounding environment from radioactive contamination. Since 1999, BPFK (Biro Pengawalan Farmaseutikal Kebangsaan) has used the guidelines from Pharmaceutical Inspection Convention Scheme (PICS) to meet the requirements of the Good Manufacturing Practice (GMP) for Pharmaceutical Products. In the guidelines, the pharmaceutical production facility shall be designed based on clean room environment. In order to design a radiopharmaceutical production facility, it is important to combine the concept of radiation safety and clean room to ensure that both requirements from GMP and IAEA are met. The design requirement is necessary to set up a complete radiopharmaceutical production facility, which is safe, has high production quality and complies with the Malaysian and International standards.

Consumer Intervention Mapping—A Tool for Designing Future Product Strategies within Circular Product Service Systems

Directory of Open Access Journals (Sweden)

Matt Sinclair

2018-06-01

Full Text Available Re-distributed manufacturing presents a number of opportunities and challenges for New Product Development in a future Circular Economy. It has been argued that small-scale, flexible and localised production systems will reduce resource consumption, lower transport emissions and extend product lifetimes. At the same time smart products within the Internet of Things will gather and report data on user behaviour and product status. Many sustainable design tools have previously been developed but few are able to imagine and develop visions of how future sustainable product service systems might be manifested. This paper introduces the concept of Consumer Intervention Mapping as a tool for creating future product strategies. The tool visualises the points within a product’s lifecycle where stakeholders are able to intervene in the product’s expected journey. This perspective enables the rapid construction of scenarios that explore and describe future circular product service systems. Validation of the tool in three workshops is described and the outcomes are presented. Consumer Intervention Mapping is successful in creating scenarios that describe existing product service systems and new product concepts adapted to a Circular Economy paradigm. Further work is required to refine the tool’s performance in more focused and reflective design exercises.

From Product to Service Design: A Thinking Paradigm Shift

Directory of Open Access Journals (Sweden)

Liliana Rodriguez

2014-12-01

Full Text Available Society, industry and the economy are all experiencing changes caused by a shift from products to services. While a “problem-solving” approach is commonly used for the development of products, new design approaches are needed as the primary unit of exchange moves from goods to services.  This research argues that a fundamental transformation in the design world is taking place, manifested in a thinking paradigm shift from problem solving (designing products towards systems thinking (designing services. This paper draws on design literature to identify concepts of systems thinking and problem solving to help understand core elements in the shift from product to service design. It also reports on a series of semi-structured interviews with designers working in five design consultancies that have moved from product design to services design. The results show a change in the way designers think and approach projects when facing the challenges of designing services, confirming a movement from problem solving to systems thinking. However, systems thinking is not replacing problem solving but complementing it. The results also indicate that the growing complexity of the issues designers deal with influences the adoption of systems thinking in responding to service design challenges, as well as current changes in people’s ideas about sustainability and  society.

Zhang, Fuying; Lu, Ximei; Wang, Ping; Liu, Hui

Product innovative design in companies today relies heavily on individual members’ experience and creative ideation as well as their skills of integrating creativity and innovation tools with design methods agilely. Creative ideation and inventive ideas generation are two crucial stages in product innovative design process. Ideal solution is the desire final ideas for given problem, and the striving reaching target for product design. In this paper, a product innovative design process driven by ideal solution is proposed. This design process encourages designers to overcome their psychological inertia, to foster creativity in a systematic way for acquiring breakthrough creative and innovative solutions in a reducing sphere of solution-seeking, and results in effective product innovative design rapidly. A case study example is also presented to illustrate the effectiveness of the proposed design process.

Bio-based products are made from renewable materials, offering a promising basis for the production of sustainable chemicals, materials, and more complex articles. However, biomass is not a limitless resource or one without environmental and social impacts. Therefore, while it is important to use biomass and grow a bio-based economy, displacing the unsustainable petroleum basis of energy and chemical production, any resource must be used effectively to reduce waste. Standards have been developed to support the bio-based product market in order to achieve this aim. However, the design of bio-based products has not received the same level of attention. Reported here are the first steps towards the development of a framework of understanding which connects product design to resource efficiency. Research and development scientists and engineers are encouraged to think beyond simple functionality and associate value to the potential of materials in their primary use and beyond.

Incorporating anthropometry into design of ear-related products.

Science.gov (United States)

Liu, Bor-Shong

2008-01-01

To achieve mass customization and collaborative product design, human factors and ergonomics should play a key development role. The purpose of this study was to provide product designers with the anthropometic dimensions of outer ears for different demographic data, including gender and age. The second purpose was to compare the dimensions of various ear-related products (i.e., earphone, bluetooth earphone and ear-cup earphone) with the anthropometic database and recommend appropriate solutions for design. Two hundred subjects aged 20-59 was selected for this study and divided into four age stratifications. Further, three different dimensions of the outer ear (i.e., the earhole length, the ear connection length and the length of the pinna) were measured by superimposed grid photographic technique. The analysis of variance (ANOVA) was used to investigate the effects of gender, and age on ear dimensions. The results showed that all ear dimensions had significant gender effects. A comparison between the anthropometric dimensions and those of current products revealed that most current ear-related products need to be redesigned using anthropometric data. The shapes of earhole and pinna are not circular. Consequently, ear products need to be elongated so that users may feel more comfortably and not have the product slip off easily.

By-products by design

International Nuclear Information System (INIS)

Collins, Richard

2011-01-01

Full text: Some mining by-products that are currently stockpiled or disposed of could be put to use preventing nutrients from entering river systems, helping reduce the potential for algal blooms. A joint project between CSIRO and the Western Australia (WA) Department of Water investigated a range of spent materials from mining and industry to determine their ability to filter nutrients from natural waters or to treat wastewater. “The largely unexploited by-product materials we generate in Western Australia could be developed as 'designer' contaminant adsorbents,” said CSIRO project leader Dr Grant Douglas. The use of abundant, low-cost wastes generated from mineral processing, in particular, offers a potentially cost- effective and environmentally-friendly strategy for removing nutrients. “The productive use of the by-products also has the potential to reduce the environmental footprint of mining and mineral processing industries by lowering by-product stockpiles,” he said. But the key benefits are in water; not only improving the health of surface waters but, by facilitating reuse, also easing the competition for water resources in an increasingly climate constrained part of the country. Re-use of industrial by-products in WA is currently considered on a case-by-case basis rather than regulated according to established standards. The project aimed to inject some rigour by characterising for the first time the nutrient, trace element uptake and acid neutralising capacity of a range of low-cost by-products (see Fact File). It also underpinned the development of a draft protocol for screening similar by-products in the future. The comprehensive characterisation included identification and procurement, and basic characterisation of by-products included major and trace element geochemistry, mineralogy, radioactivity, geochemical modelling and leachate chemistry and toxicity. These inherent properties and suitability of by-products for potential environmental

PRALEA Jeni

2015-05-01

Full Text Available This paper presents the role and importance of experimental research in design activity. The designer, as a researcher and a project manager, proposes to establish a relationship between functional-aesthetic-constructive-technological-economic,based on the aesthetic possibilities of the materials used for the experiments. With the aim to identify areas for the application of leather waste resulted from the production process, the paper presents experiments conducted with this material in combination with wood, by using different techniques that lead to different aesthetic effects. Identifying the areas to use and creating products from leather and/or wood waste, is based on the properties of these materials. Leather, the subject of these experiments, has the advantage that it can be used on both sides. Tactile differences of the two sides of this material has both aesthetical and functional advantages, which makes it suitable for applications on products that meet the requirements of "design for all". With differentiated tactile characteristics, in combination with other materials, for these experiments wood, easily "read touch" products can be generated to help people with certain disabilities. Thus, experiments presented in this paper allows the establishment of aesthetic schemes applicable to products that are friendly both with the environment (based on the reuse of wood and leather waste and with the users (can be used as applications, accessories and concepts of products for people with certain disabilities. The designer’s choices or decisions can be based on the results of this experiment. The experiment enables the designer to develop creative, innovative and environmentally friendly products.

With the increasing of complexity of complex mechatronic products, it is necessary to involve multidisciplinary design teams, thus, the traditional customer requirements modeling for a single discipline team becomes difficult to be applied in a multidisciplinary team and project since team members with various disciplinary backgrounds may have different interpretations of the customers' requirements. A new synthesized multidisciplinary customer requirements modeling method is provided for obtaining and describing the common understanding of customer requirements (CRs) and more importantly transferring them into a detailed and accurate product design specifications (PDS) to interact with different team members effectively. A case study of designing a high speed train verifies the rationality and feasibility of the proposed multidisciplinary requirement modeling method for complex mechatronic product development. This proposed research offersthe instruction to realize the customer-driven personalized customization of complex mechatronic product.

The Design and Development of Enhanced Thermal Desorption Products

Directory of Open Access Journals (Sweden)

R. Humble

2005-01-01

Full Text Available This research study is based on a knowledge-transfer collaboration between The National Centre for Product Design and Development Research (PDR and Markes International Ltd. The aim of the two-year collaboration has been to implement design tools and techniques for the development of enhanced thermal desorption products. Thermal desorption is a highly-specialised technique for the analysis of trace-level volatile organic compounds. This technique allows minute quantities of these compounds to be measured; however, there is an increasing demand from customers for greater sensitivity over a wider range of applications, which means new design methodologies need to be evaluated. The thermal desorption process combines a number of disparate chemical, thermal and mechanical disciplines, and the major design constraints arise from the need to cycle the sample through extremes in temperature. Following the implementation of a comprehensive product design specification, detailed design solutions have been developed using the latest 3D CAD techniques. The impact of the advanced design techniques is assessed in terms of improved product performance and reduced development times, and the wider implications of new product development within small companies are highlighted.

Caruso, Giandomenico; Re, Guido Maria

2010-01-01

The product development process, of industrial products, includes a phase dedicated to the design review that is a crucial phase where various experts cooperate in selecting the optimal product shape. Although computer graphics allows us to create very realistic virtual representations of the products, it is not uncommon that designers decide to build physical mock-ups of their newly conceived products because they need to physically interact with the prototype and also to evaluate the product within a plurality of real contexts. This paper describes the hardware and software development of our Augmented Reality design review system that allows to overcome some issues related to the 3D visualization and to the interaction with the virtual objects. Our system is composed by a Video See Through Head Mounted Display, which allows to improve the 3D visualization by controlling the convergence of the video cameras automatically, and a wireless control system, which allows us to create some metaphors to interact with the virtual objects. During the development of the system, in order to define and tune the algorithms, we have performed some testing sessions. Then, we have performed further tests in order to verify the effectiveness of the system and to collect additional data and comments about usability and ergonomic aspects.

This paper will discuss the design development, manufacturing and testing of knitted products maximizing the use of new innovations in Nano- technology and the integration of Phase Changing Materials specifically for diabetics. The project identified key aspects requiring design solutions to bring improvement to the circulatory problems with specific reference to the diabetic condition. Diabetics have particular difficulty in regulating their body temperature and this can result in the condition worsening, and resulting in loss of digits or limbs. The design of products to prevent the deterioration of the diabetic condition and to help those with limb loss was developed in collaboration with a Northern Ireland diabetic consultant, a product engineer and a knitwear designer. The fusion of ideas between the stakeholders resulted in the development and manufacture of a range of products that have been successfully tested at the yarn and fabric development stage and have been proven to maintain body temperature by either cooling or warming and therefore bring improvement to health and well-being. Whilst the product has a performance element the design ideas created desirable products that not only provided solutions to the brief but also resulted in products that had further market applications.

Product design refers to a system of processes from confirming a product’s specifications to product’s structure. Form, technology, and needs must be considered simultaneously to ensure qualities. In recent years, with the advancement of smartphone technology, many products are connected with apps. Designers cannot exclude themselves from this new wave of the trend. In this article, household hydroponic products design is used as an example, to show the close relationship between digital mobile technology and product design in the contemporary world. Regularly measure the amount of liquid to be added is difficult for a consumer who has no professional experience. To facilitate the introduction of small-scale aquaculture systems into the home, we proposed sensor hardware combined with App software, measured EC and pH value and transmitted to the phone. The app can calculate and display the amount of added and control the amount of inserted through a Bluetooth connection. The physical design needs to take into account the connection between the electronic parts and the circuit board, and interface operation. Thus, not only the model of the product but also the user interface has to be integrated to show the product's quality completely. Besides, authors made reflection upon the necessity for adjustments for interdisciplinary courses under the changing digital mobile era. Also, under the current curriculum structure, possible teaching approach is expressed for extending student’s feasibility.

The green alga Chlamydomonas reinhardtii has the ability to produce molecular hydrogen (H2), a clean and renewable fuel, through the biophotolysis of water under sulphur-deprived anaerobic conditions. The aim of this study was to advance the development of a practical and scalable biophotolytic H2 production process. Experiments were carried out using a purpose-built flat-plate photobioreactor, designed to facilitate green algal H2 production at the laboratory scale and equipped with a membrane-inlet mass spectrometry system to accurately measure H2 production rates in real time. The nutrient control method of sulphur deprivation was used to achieve spontaneous H2 production following algal growth. Sulphur dilution and sulphur feed techniques were used to extend algal lifetime in order to increase the duration of H2 production. The sulphur dilution technique proved effective at encouraging cyclic H2 production, resulting in alternating Chlamydomonas reinhardtii recovery and H2 production stages. The sulphur feed technique enabled photobioreactor operation in chemostat mode, resulting in a small improvement in H2 production duration. A conceptual design for a large-scale photobioreactor was proposed based on these experimental results. This photobioreactor has the capacity to enable continuous and economical H2 and biomass production using green algae. The success of these complementary approaches demonstrate that engineering advances can lead to improvements in the scalability and affordability of biophotolytic H2 production, giving increased confidence that H2 can fulfil its potential as a sustainable fuel of the future.

Engineering microbial cell factories for the production of plant natural products: from design principles to industrial-scale production.

Plant natural products (PNPs) are widely used as pharmaceuticals, nutraceuticals, seasonings, pigments, etc., with a huge commercial value on the global market. However, most of these PNPs are still being extracted from plants. A resource-conserving and environment-friendly synthesis route for PNPs that utilizes microbial cell factories has attracted increasing attention since the 1940s. However, at the present only a handful of PNPs are being produced by microbial cell factories at an industrial scale, and there are still many challenges in their large-scale application. One of the challenges is that most biosynthetic pathways of PNPs are still unknown, which largely limits the number of candidate PNPs for heterologous microbial production. Another challenge is that the metabolic fluxes toward the target products in microbial hosts are often hindered by poor precursor supply, low catalytic activity of enzymes and obstructed product transport. Consequently, despite intensive studies on the metabolic engineering of microbial hosts, the fermentation costs of most heterologously produced PNPs are still too high for industrial-scale production. In this paper, we review several aspects of PNP production in microbial cell factories, including important design principles and recent progress in pathway mining and metabolic engineering. In addition, implemented cases of industrial-scale production of PNPs in microbial cell factories are also highlighted.

Mitta, D A; Flores, P L

1995-12-01

Increased operator productivity is a desired outcome of user-CAD interaction scenarios. Two objectives of this research were to (1) define a measure of operator productivity and (2) empirically investigate the potential effects of CAD interface design on operator productivity, where productivity is defined as the percentage of a drawing session correctly completed per unit time. Here, AutoCAD provides the CAD environment of interest. Productivity with respect to two AutoCAD interface designs (menu, template) and three task types (draw, dimension, display) was investigated. Analysis of user productivity data revealed significantly higher productivity under the menu interface condition than under the template interface condition. A significant effect of task type was also discovered, where user productivity under display tasks was higher than productivity under the draw and dimension tasks. Implications of these results are presented.

2018-04-01

To compete in today’s ever-growing technology market, a product needs to be well presentable to the customers. It is a challenge to design a product that is able to attract customer’s attention and to build their loyalty towards the product. A product needs to be designed with focus to give the maximum level of satisfaction to the end user which is the customer. That is the focus of this paper, to achieve customer’s satisfaction, by studying feelings and emotional value related to product designs using Kansei Engineering (KE) and to test how important that product element (level of satisfaction) by using Kano Method (KM). KE is a method of translating human emotions and feelings into product development. The method studies the human interaction and responses when a customer sees a product, then translates it into a new improved design. However, KE cannot stand on its own. It did not specify in which extends the feeling or emotions is important in a product. After we had the design appearance parameters from KE and existing design evaluation, it need to be classified which is more important than the other is. That is why Kano Method (KM) will also be used. Since this scope of study towards an emotional feeling of design (existing part/appearance) in Kano categories not in deep function of technical requirement, so KM will help to classify parts of product into categories, which part will give fully satisfaction while using it. It studies the more important attributes considered by the customers for improvement. The objective is to find out the design priority guide that can be used to maximize customer’s satisfaction. Therefore, in order to apply the qualitative measurement idea into the real situation, the headphone product is chosen (popular among students) as the product (the appearance of part, feeling when use it) domain for this study. As the results progressed, it was found out that the headband part of headphone is the most important part of the

DESIGN CONSIDERATIONS UPON PRODUCT END-OF-LIFE OPTIONS

Directory of Open Access Journals (Sweden)

BARSAN Lucian

2016-11-01

Full Text Available The paper presents some considerations about the necessity of evaluating the environmental impact of a product during its entire life. The present situation (economic, social and ecologic imposes solutions to reduce this impact as a result of an analysis performed during all stages of the life cycle. This paper focuses on design solutions with consequences in the last stage, the end-of-life. Reusing products, with, or without remanufacturing and recycling the materials from products that cannot be reused represent some options analysed in this paper. The end-of-life options should be known even from the beginning of the design process and should be included as design objectives or, at least as constrictions. Considering them as human needs would naturally include them in the requirements list.

Visschers, Vivianne H M; Hess, Rebecca; Siegrist, Michael

2010-07-01

In the present study we investigated consumers' visual attention to nutrition information on food products using an indirect instrument, an eye tracker. In addition, we looked at whether people with a health motivation focus on nutrition information on food products more than people with a taste motivation. Respondents were instructed to choose one of five cereals for either the kindergarten (health motivation) or the student cafeteria (taste motivation). The eye tracker measured their visual attention during this task. Then respondents completed a short questionnaire. Laboratory of the ETH Zurich, Switzerland. Videos and questionnaires from thirty-two students (seventeen males; mean age 24.91 years) were analysed. Respondents with a health motivation viewed the nutrition information on the food products for longer and more often than respondents with a taste motivation. Health motivation also seemed to stimulate deeper processing of the nutrition information. The student cafeteria group focused primarily on the other information and did this for longer and more often than the health motivation group. Additionally, the package design affected participants' nutrition information search. Two factors appear to influence whether people pay attention to nutrition information on food products: their motivation and the product's design. If the package design does not sufficiently facilitate the localization of nutrition information, health motivation can stimulate consumers to look for nutrition information so that they may make a more deliberate food choice.

Strategies for designing novel functional meat products.

Science.gov (United States)

Arihara, Keizo

2006-09-01

In recent years, much attention has been paid to physiological functions of foods due to increasing concerns for health. Although there has been limited information of physiological functions of meat until recently, several attractive meat-based bioactive compounds, such as carnosine, anserine, l-carnitine, conjugated linoleic acid, have been studied. Emphasizing these activities is one possible approach for improving the health image of meat and developing functional meat products. This article provides potential benefits of representative meat-based bioactive compounds on human health and an overview of meat-based functional products. Strategies for designing novel functional meat products utilizing bioactive peptides and/or probiotic bacteria, is also discussed. This article focuses particularly on the possibility of meat protein-derived bioactive peptides, such as antihypertensive peptides. There are still some hurdles in developing and marketing novel functional meat products since such products are unconventional and consumers in many countries recognize meat and meat products to be bad for health. Along with accumulation of scientific data, there is an urgent need to inform consumers of the exact functional value of meat and meat products including novel functional foods.

Design control considerations for biologic-device combination products.

Science.gov (United States)

Anderson, Dave; Liu, Roger; Anand Subramony, J; Cammack, Jon

2017-03-01

Combination products are therapeutic and diagnostic medical products that combine drugs, devices, and/or biological products with one another. Historically, biologics development involved identifying efficacious doses administered to patients intravenously or perhaps by a syringe. Until fairly recently, there has been limited focus on developing an accompanying medical device, such as a prefilled syringe or auto-injector, to enable easy and more efficient delivery. For the last several years, and looking forward, where there may be little to distinguish biologics medicines with relatively similar efficacy profiles, the biotechnology market is beginning to differentiate products by patient-focused, biologic-device based combination products. As innovative as biologic-device combination products are, they can pose considerable development, regulatory, and commercialization challenges due to unique physicochemical properties and special clinical considerations (e.g., dosing volumes, frequency, co-medications, etc.) of the biologic medicine. A biologic-device combination product is a marriage between two partners with "cultural differences," so to speak. There are clear differences in the development, review, and commercialization processes of the biologic and the device. When these two cultures come together in a combination product, developers and reviewers must find ways to address the design controls and risk management processes of both the biologic and device, and knit them into a single entity with supporting product approval documentation. Moreover, digital medicine and connected health trends are pushing the boundaries of combination product development and regulations even further. Despite an admirable cooperation between industry and FDA in recent years, unique product configurations and design features have resulted in review challenges. These challenges have prompted agency reviewers to modernize consultation processes, while at the same time, promoting

Designing future products: what difficulties do designers encounter and how can their creative process be supported?

Science.gov (United States)

Bonnardel, Nathalie

2012-01-01

To remain competitive, companies must regularly offer new products to consumers. A major challenge for designers is therefore to come up with design solutions and define products that are both new and adapted to future users and usages. Although classic methods and ergonomic recommendations are useful in most run-of-the-mill design contexts, they are of limited benefit when the design situation requires greater creativity. This paper therefore addresses issues related to product design by pursuing a triple objective: (1) highlight the difficulties encountered by designers in imagining and conceiving new products, (2) find out which conditions could help designers come up with creative ideas for innovative products, and (3) suggest methods and tools to support designers' creative process and help them take other stakeholders' needs and expectations into consideration.

Enabling Product Design Reuse by Long-term Preservation of Engineering Knowledge

Directory of Open Access Journals (Sweden)

Jörg Brunsmann

2009-12-01

Full Text Available In the highly competitive engineering industry, product innovations are created with the help of a product lifecycle management (PLM tool chain. In order to support fast-paced product development, a major company goal is the reuse of product designs and product descriptions. Due to the product’s complexity, the design of a product not only consists of geometry data but also of valuable engineering knowledge that is created during the various PLM phases. The need to preserve such intellectual capital leads engineering companies to introduce knowledge management and archiving their machine-readable formal representation. However, archived knowledge is in danger of becoming unusable since it is very likely that knowledge semantics and knowledge representation will evolve over long time periods, for example during the 50 operational years of some products. Knowledge evolution and knowledge representation technology changes are crucial issues since a reuse of the archived product information can only be ensured if its rationale and additional knowledge are interpretable with future software and technologies. Therefore, in order to reuse design data fully, knowledge about the design must also be migrated to be interoperable with future design systems and knowledge representation methods. This paper identifies problems, issues, requirements, challenges and solutions that arise while tackling the long-term preservation of engineering knowledge.

Full Text Available The important problem in design of rubber-metal products is the optimization of their mass without sacrificing of proportionality factor is in the limits of standard. Aim: The aim of this work is to improve the computer-aided systems by development and implementation of improved optimization method in rubber-metal CAD systems for designers based on the reverse optimization. Materials and Methods: The paper studies the matters of computer-aided structural design of technical composite products composed of anisotropic materials that are essentially different in properties. Results: The structure of CAD systems for designers solving the problems of such design is offered and the work principles of its subsystems are described. It is shown that complicated systems optimization in CAD systems must consider as restrictions the entitative connection between separate elements of these systems within the area of the optimizing arguments. Conclusions: The problem of the “reverse” optimization when objective functions are the connectivity area parameters is considered. In many cases, this allows receiving solutions that are more effective during the computer-aided design process. The developed CAD system for designers was used during the production of rubber-metal shock absorbers at the Odessa Rubber Technical Articles Plant. The positive technical and economic effect was obtained.

How Axiomatic Design can promote creativity in the design of new products

Directory of Open Access Journals (Sweden)

Gabriel-Santos António

2017-01-01

Full Text Available In product development, creativity is the driving force for doing something that leads to innovation. A typical ideation background has three subsystems: inspiration, dematerialization and recombination. The most basic concepts of Axiomatic Design, i.e. domains, hierarchies and zigzagging, as well as the two design axioms, provide a powerful framework to implement ideation, as to make creativity easier when developing a new product. The result of dematerialization is in the functional domain, which is the place where the customer needs are presented by functional requirements and purged of any kind of physical bias. The recombination creates the design parameters, at the physical domain, which are the set of elements of the design object that have been chosen to satisfy the functional requirements, into a new materialization profile of a new product. In this paper, a concrete case illustrating the above-mentioned concepts is presented.

An integrated design experience on a wet-tree production semisubmersible

Energy Technology Data Exchange (ETDEWEB)

Fales, Raymond P.; Lee, Craig; Chen Xiang; Zhengquan Zhou [ABB FPS Houston, TX (United States)

2004-07-01

The semisubmersible platform has been a reliable work platform for the offshore oil and gas industry for over 40 years. The Semisubmersible is a very mature concept with hundreds of examples in use. Traditionally during the design phase, the motions have been developed to suit the independent services, drilling, offshore operations or production. However, recently with the move to ultra-deep water depths and the use of Steel Catenary Risers (SCRs), the design of Semisubmersible has to be considered as an integrated floating production system, to satisfy all the requirements from platform global performance, SCRs strength and fatigue, mooring, topside payload and layout, hull strength, deck structure, marine system layout, stability, fabrication and installation. These requirements usually conflict each other. As such it is imperative to consider them together, adjusting the design parameters during design loops to obtain an optimal design product. This paper will describe the integrated design process used and the optimal design principles applied to satisfy these conflicting requirements and provide an example of a wet-tree production semisubmersible integrated design. Particular emphasis will be on global performance, SCR design, deck structure arrangement options, fabrication and integration. (author)

Crowdsourcing New Product Design on the Web: An Analysis of Online Designer Platform Service

2013-01-01

Full Text Available A designer is a core resource in the fashion industry. Successful designers need to be creative and quick to understand the business and wider environment in which they are operating. The Designer Platform Service (DPS, which combines the mechanism of crowdsourcing and group buying on the web, provides a platform for entrant designers to try their abilities in the real market practice. Freelance designers post design samples or sketches of products on the website of DPS, and consumers may preorder the products (each at a fixed price online based on the design information. Once the number of ordering reaches or passes a certain threshold, that is, the minimum production quantity (MPQ, DPS will arrange for production and delivery according to the orders received. This novel service boosts the growth of entrant designers and links designing works with real markets directly. We are interested in how the price and MPQ decisions are made in DPS, with consideration of the entrant designer's objective, decision sequences, and customer demand structures. We develop Stackelberg games to model and derive the equilibrium solutions under individual scenarios. Our findings suggest feasibility of the DPS business model.

A Bayesian Network Based Adaptability Design of Product Structures for Function Evolution

Directory of Open Access Journals (Sweden)

Shaobo Li

2018-03-01

Full Text Available Structure adaptability design is critical for function evolution in product families, in which many structural and functional design factors are intertwined together with manufacturing cost, customer satisfaction, and final market sales. How to achieve a delicate balance among all of these factors to maximize the market performance of the product is too complicated to address based on traditional domain experts’ knowledge or some ad hoc heuristics. Here, we propose a quantitative product evolution design model that is based on Bayesian networks to model the dynamic relationship between customer needs and product structure design. In our model, all of the structural or functional features along with customer satisfaction, manufacturing cost, sale price, market sales, and indirect factors are modeled as random variables denoted as nodes in the Bayesian networks. The structure of the Bayesian model is then determined based on the historical data, which captures the dynamic sophisticated relationship of customer demands of a product, structural design, and market performance. Application of our approach to an electric toothbrush product family evolution design problem shows that our model allows for designers to interrogate with the model and obtain theoretical and decision support for dynamic product feature design process.

Affective design identification on the development of batik convection product

Science.gov (United States)

Prastawa, H.; Purwaningsih, R.

2017-11-01

The affective design is increasingly applied to product development in order to meet the desires and preferences of customers. Batik is a traditional Indonesian culture containing historical and cultural values. The development of batik design is one of the efforts to strengthen the identity and superiority of Indonesia’s creative industries as well as to preserve batik as the cultural heritage of the nation. Batik product designs offered by the manufacturers do not necessarily correspond with the wishes of consumers, especially the affective values involved. Therefore it is necessary to identify consumer perceptions of convection- based batik product in the form of clothing and fabrics, especially the affective value as the consideration for the designer or manufacturer to develop design alternatives to batik convection products. This research aims to obtain information on consumer affective value, to identify the affective value perception differences among X and Y Generation and to classify affective value in the corresponding cluster of the batik products convection. This study uses Kansei engineering to determine the perception of affective design in the form of Kansei word. Cluster Analysis was used to form clusters that classify affective value of the same class. The results showed that there were 16 pairs of Kansei word which was worth as an affective consumer desire, the 3 indicators that had significant differences among X and Y Generation and 4 clusters with different characteristics.

Significant milestones have been attained towards the technology development field testing and commercialization of direct fuel cell power plant since the 1994 Fuel Cell Seminar. Under a 5-year cooperative agreement with the Department of Energy signed in December 1994, Energy Research Corporation (ERC) has been developing the design for a MW-scale direct fuel cell power plant with input from previous technology efforts and the Santa Clara Demonstration Project. The effort encompasses product definition in consultation with the Fuel Cell Commercialization Group, potential customers, as well as extensive system design and packaging. Manufacturing process improvements, test facility construction, cell component scale up, performance and endurance improvements, stack engineering, and critical balance-of-plant development are also addressed. Major emphasis of this product design improvement project is on increased efficiency, compactness and cost reduction to establish a competitive place in the market. A 2.85 MW power plant with an efficiency of 58% and a footprint of 420 m{sup 2} has been designed. Component and subsystem testing is being conducted at various levels. Planning and preparation for verification of a full size prototype unit are in progress. This paper presents the results obtained since the last fuel cell seminar.

A structure-based approach to evaluation product adaptability in adaptable design

International Nuclear Information System (INIS)

Cheng, Qiang; Liu, Zhifeng; Cai, Ligang; Zhang, Guojun; Gu, Peihua

2011-01-01

Adaptable design, as a new design paradigm, involves creating designs and products that can be easily changed to satisfy different requirements. In this paper, two types of product adaptability are proposed as essential adaptability and behavioral adaptability, and through measuring which respectively a model for product adaptability evaluation is developed. The essential adaptability evaluation proceeds with analyzing the independencies of function requirements and function modules firstly based on axiomatic design, and measuring the adaptability of interfaces secondly with three indices. The behavioral adaptability reflected by the performance of adaptable requirements after adaptation is measured based on Kano model. At last, the effectiveness of the proposed method is demonstrated by an illustrative example of the motherboard of a personal computer. The results show that the method can evaluate and reveal the adaptability of a product in essence, and is of directive significance to improving design and innovative design

Applying Human-Centered Design Methods to Scientific Communication Products

Science.gov (United States)

Burkett, E. R.; Jayanty, N. K.; DeGroot, R. M.

2016-12-01

Knowing your users is a critical part of developing anything to be used or experienced by a human being. User interviews, journey maps, and personas are all techniques commonly employed in human-centered design practices because they have proven effective for informing the design of products and services that meet the needs of users. Many non-designers are unaware of the usefulness of personas and journey maps. Scientists who are interested in developing more effective products and communication can adopt and employ user-centered design approaches to better reach intended audiences. Journey mapping is a qualitative data-collection method that captures the story of a user's experience over time as related to the situation or product that requires development or improvement. Journey maps help define user expectations, where they are coming from, what they want to achieve, what questions they have, their challenges, and the gaps and opportunities that can be addressed by designing for them. A persona is a tool used to describe the goals and behavioral patterns of a subset of potential users or customers. The persona is a qualitative data model that takes the form of a character profile, built upon data about the behaviors and needs of multiple users. Gathering data directly from users avoids the risk of basing models on assumptions, which are often limited by misconceptions or gaps in understanding. Journey maps and user interviews together provide the data necessary to build the composite character that is the persona. Because a persona models the behaviors and needs of the target audience, it can then be used to make informed product design decisions. We share the methods and advantages of developing and using personas and journey maps to create more effective science communication products.

Application of Absorption Modeling in Rational Design of Drug Product Under Quality-by-Design Paradigm.

Science.gov (United States)

Kesisoglou, Filippos; Mitra, Amitava

2015-09-01

Physiologically based absorption models can be an important tool in understanding product performance and hence implementation of Quality by Design (QbD) in drug product development. In this report, we show several case studies to demonstrate the potential application of absorption modeling in rational design of drug product under the QbD paradigm. The examples include application of absorption modeling—(1) prior to first-in-human studies to guide development of a formulation with minimal sensitivity to higher gastric pH and hence reduced interaction when co-administered with PPIs and/or H2RAs, (2) design of a controlled release formulation with optimal release rate to meet trough plasma concentrations and enable QD dosing, (3) understanding the impact of API particle size distribution on tablet bioavailability and guide formulation design in late-stage development, (4) assess impact of API phase change on product performance to guide specification setting, and (5) investigate the effect of dissolution rate changes on formulation bioperformance and enable appropriate specification setting. These case studies are meant to highlight the utility of physiologically based absorption modeling in gaining a thorough understanding of the product performance and the critical factors impacting performance to drive design of a robust drug product that would deliver the optimal benefit to the patients.

Integrated design strategy for product life-cycle management

Science.gov (United States)

Johnson, G. Patrick

2001-02-01

Two major trends suggest new considerations for environmentally conscious manufacturing (ECM) -- the continuation of dematerialization and the growing trend toward goods becoming services. A diversity of existing research could be integrated around those trends in ways that can enhance ECM. Major research-based achievements in information, computation, and communications systems, sophisticated and inexpensive sensing capabilities, highly automated and precise manufacturing technologies, and new materials continue to drive the phenomenon of dematerialization - the reduction of the material and energy content of per capita GDP. Knowledge is also growing about the sociology, economics, mathematics, management and organization of complex socio-economic systems. And that has driven a trend towards goods evolving into services. But even with these significant trends, the value of material, energy, information and human resources incorporated into the manufacture, use and disposal of modern products and services often far exceeds the benefits realized. Multi-disciplinary research integrating these drivers with advances in ECM concepts could be the basis for a new strategy of production. It is argued that a strategy of integrating information resources with physical and human resources over product life cycles, together with considering products as streams of service over time, could lead to significant economic payoff. That strategy leads to an overall design concept to minimize costs of all resources over the product life cycle to more fully capture benefits of all resources incorporated into modern products. It is possible by including life cycle monitoring, periodic component replacement, re-manufacture, salvage and human factor skill enhancement into initial design.

Linking product design to consumer behavior: the moderating role of consumption experience.

Science.gov (United States)

Gilal, Naeem Gul; Zhang, Jing; Gilal, Faheem Gul

2018-01-01

Previous investigations of product design broadly link aesthetic, functional, and symbolic designs to sales growth, high turnover, and market share. However, the effect of product design dimensions on consumer willingness-to-buy (WTB) and word-of-mouth (WOM) is virtually ignored by consumer researchers. Similarly, whether the consumption experience can differentiate the effect of the three product design dimensions on WTB and WOM is completely unknown. Using categorization theory as a lens, our study aims to explore the effect of product design dimensions on consumer WTB and WOM directly and indirectly through the moderation of the consumption experience. A convenience sample of (n=357) Chinese and (n=277) Korean shoppers was utilized to test the hypotheses in the fashion apparel industry. Our results showed that the aesthetic design was more prominent in capturing consumer WTB for both Chinese and Koreans. Similarly, the aesthetic design was more salient in enhancing WOM for Chinese, whereas the symbolic design was more promising in terms of improving WOM for Koreans. Further, our moderation results demonstrated that the consumption experience could differentiate the effects of the three product design dimensions on consumer WTB and WOM for Chinese. By contrast, the consumption experience could only interact with the aesthetic design to improve WOM for South Koreans. To the best of authors' knowledge, the present study is one of the initial attempts to link three product design dimensions with consumer WTB and WOM in the fashion apparel context and explored whether consumption experience competes or complement with three product design dimensions to shape consumer WTB and WOM for Chinese and Koreans.

A Method of Numerical Control Equipment Appearance Design Based on Product Identity

Science.gov (United States)

Zhu, Zhijuan; Zhou, Qi; Li, Bin; Visser, Steve

Research on numerical control (NC) equipment has been more and more abundant; however, there are few existing studies in the field of appearance design for NC equipments. This paper provided a method to generate new appearance design of NC equipments based on product identity (PI). For the purpose of providing guidelines to generate new concept of NC equipment design, this paper, therefore, took the DMG Company (a Germen NC equipment company) as a case, examined the total products of this company from two aspects: Product Image and Product Family. Task 1 was an evaluate task about the Product Image by using the semantic differential (SD) evaluation method; Task 2 was a study task about Product Family to find out features of the products and classify these features. During the Task 2, several features have been found out and summarized, and these features were classified into 3 different levels according to their frequency and importance. In the end, two appearance design samples have been generated based on the analysis above to prove the application of the research.

Innovation in product design as a factor for reducing logistic and production costs

Directory of Open Access Journals (Sweden)

Luciana Fighera Marzall

2016-03-01

Full Text Available Innovation has been considered of fundamental importance for organizations competing in dynamic environments, which along with cost management has been shown as an organizational strategy that allows the company to measure its results and implement measures that impact on the organization's performance as a whole. This paper, carried out in a metal mechanical industry of a telecommunications engineering branch, aims to analyse cost reduction in logistics raw materials areas through innovation in the product design, which are antennas and towers for telephone networks. In terms of methodology, this study presents itself as a qualitative and quantitative research-action, which from the link between theory and practice allows for intervention in the middle of the researchers studied. As a result, an innovative project was developed, which allowed for the reduction costs of production by 68% and logistics by 32%. Despite the significant decrease in costs, the quality of manufactured products not declined and customer needs were met, thus making the company more competitive against competitors. Not widespread in the literature, this analysis of the impact on logistics and production costs due to improvements in the project is the main contribution theoretical of this paper.

Design of a lunar oxygen production plant

Science.gov (United States)

Radhakrishnan, Ramalingam

1990-01-01

To achieve permanent human presence and activity on the moon, oxygen is required for both life support and propulsion. Lunar oxygen production using resources existing on the moon will reduce or eliminate the need to transport liquid oxygen from earth. In addition, the co-products of oxygen production will provide metals, structural ceramics, and other volatile compounds. This will enable development of even greater self-sufficiency as the lunar outpost evolves. Ilmenite is the most abundant metal-oxide mineral in the lunar regolith. A process involving the reaction of ilmenite with hydrogen at 1000 C to produce water, followed by the electrolysis of this water to provide oxygen and recycle the hydrogen has been explored. The objective of this 1990 Summer Faculty Project was to design a lunar oxygen-production plant to provide 5 metric tons of liquid oxygen per year from lunar soil. The results of this study describe the size and mass of the equipment, the power needs, feedstock quantity and the engineering details of the plant.

Yu, Lawrence X

2008-04-01

The purpose of this paper is to discuss the pharmaceutical Quality by Design (QbD) and describe how it can be used to ensure pharmaceutical quality. The QbD was described and some of its elements identified. Process parameters and quality attributes were identified for each unit operation during manufacture of solid oral dosage forms. The use of QbD was contrasted with the evaluation of product quality by testing alone. The QbD is a systemic approach to pharmaceutical development. It means designing and developing formulations and manufacturing processes to ensure predefined product quality. Some of the QbD elements include: Defining target product quality profile; Designing product and manufacturing processes; Identifying critical quality attributes, process parameters, and sources of variability; Controlling manufacturing processes to produce consistent quality over time. Using QbD, pharmaceutical quality is assured by understanding and controlling formulation and manufacturing variables. Product testing confirms the product quality. Implementation of QbD will enable transformation of the chemistry, manufacturing, and controls (CMC) review of abbreviated new drug applications (ANDAs) into a science-based pharmaceutical quality assessment.

As the central part of a programme of enhancements in support of ITER, the Joint European Torus (JET) is being equipped with an all-metal wall. This enhancement programme requires the removal and installation of 6927 tile carriers and tiles, as well as the removal and installation of embedded diagnostics and antennas. The scale of this operation and the necessity to maximise operational availability of the facility added a requirement for high productivity in the remote activities to the existing exigencies of precision, reliability, cleanliness and operational security.

Japan Atomic Energy Agency (JAEA) has been conducting research and development for hydrogen production utilizing heat from High Temperature Gas-cooled Reactors (HTGRs). Towards the realization of nuclear hydrogen production, coupled hydrogen production plants should not be treated as an extension of a nuclear plant in order to open the door for the entry of non-nuclear industries as well as assuring reactor safety against postulated abnormal events initiated in the hydrogen production plants. Since hydrogen production plant utilizing nuclear heat has never been built in the world, little attention has been given to the establishment of a safety design for such system including the High Temperature engineering Test Reactor (HTTR). In the present study, requirements in order to design, construct and operate hydrogen production plants under conventional chemical plant standards are identified. In addition, design considerations for safety design of nuclear facility are suggested. Furthermore, feasibility of proposed safety design and design considerations are evaluated. (author)

Universally applicable design concept of stably controlling an HTGR-hydrogen production system

International Nuclear Information System (INIS)

Hada, Kazuhiko; Shibata, Taiju; Nishihara, Tetsuo; Shiozawa, Shusaku

1996-01-01

An HTGR-hydrogen production system should be designed to have stable controllability because of a large difference in thermal dynamics between reactor and hydrogen production system and such a control design concept should be universally applicable to a variety of hydrogen production processes by the use of nuclear heat from HTGR. A transient response analysis of an HTGR-steam reforming hydrogen production system showed that a steam generator installed in a helium circuit for cooling the nuclear reactor provides stable controllability of the total system, resulting in avoiding a reactor scram. A survey of control design-related characteristics among several hydrogen production processes revealed the similarity of endothermic chemical reactions by the use of high temperature heat and that steam is required as a reactant of the endothermic reaction or for preheating a reactant. Based on these findings, a system design concept with stable controllability and universal applicability was proposed to install a steam generator as a downstream cooler of an endothermic reactor in the helium circuit of an HTGR-hydrogen production system.

Product design for energy reduction in concurrent engineering: An Inverted Pyramid Approach

Science.gov (United States)

Alkadi, Nasr M.

Energy factors in product design in concurrent engineering (CE) are becoming an emerging dimension for several reasons; (a) the rising interest in "green design and manufacturing", (b) the national energy security concerns and the dramatic increase in energy prices, (c) the global competition in the marketplace and global climate change commitments including carbon tax and emission trading systems, and (d) the widespread recognition of the need for sustainable development. This research presents a methodology for the intervention of energy factors in concurrent engineering product development process to significantly reduce the manufacturing energy requirement. The work presented here is the first attempt at integrating the design for energy in concurrent engineering framework. It adds an important tool to the DFX toolbox for evaluation of the impact of design decisions on the product manufacturing energy requirement early during the design phase. The research hypothesis states that "Product Manufacturing Energy Requirement is a Function of Design Parameters". The hypothesis was tested by conducting experimental work in machining and heat treating that took place at the manufacturing lab of the Industrial and Management Systems Engineering Department (IMSE) at West Virginia University (WVU) and at a major U.S steel manufacturing plant, respectively. The objective of the machining experiment was to study the effect of changing specific product design parameters (Material type and diameter) and process design parameters (metal removal rate) on a gear head lathe input power requirement through performing defined sets of machining experiments. The objective of the heat treating experiment was to study the effect of varying product charging temperature on the fuel consumption of a walking beams reheat furnace. The experimental work in both directions have revealed important insights into energy utilization in machining and heat-treating processes and its variance based

The lean product design and development journey a practical view

CERN Document Server

Pessôa, Marcus Vinicius Pereira

2017-01-01

This book presents a series of high performance product design (PD) and development best practices that can create or improve product development organization. In contrast to other books that focus only on Toyota or other individual companies applying lean IPD, this book explains the lean philosophy more broadly and includes discussions of systems engineering, design for X (DFX), agile development, integrated product development, and project management. The “Lean Journey” proposed here takes a value-centric approach, where the lean principles are applied to PD to allow the tools and methods selected to emerge from observation of the individual characteristics of each enterprise. This means that understanding lean product development (LPD) is not about knowing which tools are available but knowing how to apply the philosophy. The book comes with an accompanying manual with problems and solutions available on Springer Extras.

2017-01-01

Product customization is a trend in the current market-oriented manufacturing environment. However, deduction from customer requirements to design results and evaluation of design alternatives are still heavily reliant on the designer's experience and knowledge. To solve the problem of fuzziness and uncertainty of customer requirements in product configuration, an analysis method based on the grey rough model is presented. The customer requirements can be converted into technical characteristics effectively. In addition, an optimization decision model for product planning is established to help the enterprises select the key technical characteristics under the constraints of cost and time to serve the customer to maximal satisfaction. A new case retrieval approach that combines the self-organizing map and fuzzy similarity priority ratio method is proposed in case-based design. The self-organizing map can reduce the retrieval range and increase the retrieval efficiency, and the fuzzy similarity priority ratio method can evaluate the similarity of cases comprehensively. To ensure that the final case has the best overall performance, an evaluation method of similar cases based on grey correlation analysis is proposed to evaluate similar cases to select the most suitable case. Furthermore, a computer-aided system is developed using MATLAB GUI to assist the product configuration design. The actual example and result on an ETC series machine tool product show that the proposed method is effective, rapid and accurate in the process of product configuration. The proposed methodology provides a detailed instruction for the product configuration design oriented to customer requirements.

Economics In Optical Design, Analysis, And Production

Science.gov (United States)

Willey, Ronald R.

1983-10-01

There are indications that we are entering an era wherein economics will play an increasing role in the optical design and production process. Economics has always been a factor in the competition between commercial ventures in the product arena. Now, we may begin to see competition between different technologies for the scarce resources of the society, including money. A proper design approach begins with a thorough examination and refinement of the requirements from the top down. The interrelationships of the various components must be properly understood and balanced. The specifications must be clear, complete, and realistic. Improper or incomplete system design can cause an extensive waste of resources. The detail optical design to meet the performance requirements has sometimes been the only part of the process that the designer has considered his own responsibility. The final optimization should also consider economic related factors: the cost of tolerances, the available tools test plates, materials, and test equipment. In the preliminary design stage, he should have decided which alignment and test methods are most appropriate to the system. The distribution of tolerances in an optical/mechanical system is a frequently neglected opportunity to reduce cost. We have reported previously on our work in this area, and expand further on it in the context of this paper. The designer now has an opportunity to generate better designs at a lower cost that are more economical to produce. The watchword for the 1980's may become the one found in the assembly automation industry: "more, better, for less".

Ergonomics and sustainability in the design of everyday use products.

Science.gov (United States)

Tosi, Francesca

2012-01-01

The relationship between Ergonomics and Design is a key element in the sustainability project, as well as in many other areas of experimental design. In the Design for Sustainability field, Ergonomics is a strategic factor for design culture innovation, providing designers with the necessary knowledge and skills regarding human characteristics and capabilities, as well as user needs and desires during use and interaction with products in work activities and everyday life. Ergonomics is also a strategic innovative factor in design development and manufacturing processes. In fact, ergonomics provides a methodological approach in user-product interaction evaluation processes through the use of participatory design and survey methods, user trials, direct observation, savings and resource conservation, etc.On the other hand, design offers solutions able to interpret user needs and expectations, at the same time suggesting new behaviors and lifestyles.In Design for Sustainability, the ergonomic and user-centered approach contributes greatly to lifestyles and innovative use of products--making it possible to understand and interpret real people needs and expectations in their everyday actions and behavior.New consumption patterns, new awareness of lifestyles, energy source consumption, purchasing methods and consumption style etc. can be supported by design innovation, responding to expressed and unexpressed user needs. With this in mind, the ergonomic approach represents the starting point for design choices and at the same time, a tool for assessing their appropriateness and effectiveness.

1990-01-01

In the summer of 1989, a collaboration between Los Alamos National Laboratory and Brookhaven National Laboratory conducted a study to establish a reference design of a facility for accelerator production of tritium (APT). The APT concept is that of a neutron-spallation source, which is based on the use of high-energy protons to bombard lead nuclei, resulting in the production of large quantities of neutrons. Neutrons from the lead are captured by lithium to produce tritium. This paper describes the design of a 1.6-GeV, 250-mA proton cw linear accelerator for APT.

MYERS, DAVID R.; MCWHORTER, PAUL J.

2000-01-01

Intelligent, integrated microsystems combine some or all of the functions of sensing, processing information, actuation, and communication within a single integrated package, and preferably upon a single silicon chip. As the elements of these highly integrated solutions interact strongly with each other, the microsystem can be neither designed nor fabricated piecemeal, in contrast to the more familiar assembled products. Driven by technological imperatives, microsystems will best be developed by multi-disciplinary teams, most likely within the flatter, less hierarchical organizations. Standardization of design and process tools around a single, dominant technology will expedite economically viable operation under a common production infrastructure. The production base for intelligent, integrated microsystems has elements in common with the mathematical theory of chaos. Similar to chaos theory, the development of microsystems technology will be strongly dependent on, and optimized to, the initial product requirements that will drive standardization--thereby further rewarding early entrants to integrated microsystem technology

Engaging young people in participatory design can be challenging, particularly in health-related projects. In a study co-designing diabetes support and information services with teenagers, we found framing activities using popular culture was a useful strategy. Various cultural references helped us stage activities that were productive for the design process, and were engaging for our young participants (e.g. exploring practical implications through discussions in a 'Dragons' Den'). Some activities were more effective than others and the idea of language-games , which has been widely explored in participatory design, explains why our strategy was successful when there was a clear 'family resemblance' between the popular cultural references and certain essential stages of designing. However, attention is required in selecting appropriate cultural references if this strategy is adopted elsewhere, and design facilitators should focus first on devising accessible language-games, rather than expecting popular cultural references to provide complete solutions to the challenge of staging participatory design.

Since hydrogen produced by nuclear should be economically competitive compared with other methods in a hydrogen society, it is important to build hydrogen production system to be coupled with the reactor as a conventional chemical plant. Japan Atomic Energy Agency started the safety study to establish a new safety philosophy to meet safety requirements for non-nuclear grade hydrogen production system. Also, structural concepts with integrating functions for the Bunsen reactor and sulphuric acid decomposer were proposed to reduce construction cost of the IS process hydrogen production system. In addition, HI decomposer which enables the process condition to be eased consisting of conventional materials and technologies was studied. Moreover, technical feasibility of the HTTR-IS system in which the hydrogen production rate of 1,000 Nm 3 /h by using the supplied heat of 10 MW from the intermediate heat exchanger of the HTTR was confirmed. This paper describes the conceptual design of the HTTR-IS hydrogen production system. (author)

Molecular design for recombinant adeno-associated virus (rAAV) vector production.

Science.gov (United States)

Aponte-Ubillus, Juan Jose; Barajas, Daniel; Peltier, Joseph; Bardliving, Cameron; Shamlou, Parviz; Gold, Daniel

2018-02-01

Recombinant adeno-associated virus (rAAV) vectors are increasingly popular tools for gene therapy applications. Their non-pathogenic status, low inflammatory potential, availability of viral serotypes with different tissue tropisms, and prospective long-lasting gene expression are important attributes that make rAAVs safe and efficient therapeutic options. Over the last three decades, several groups have engineered recombinant AAV-producing platforms, yielding high titers of transducing vector particles. Current specific productivity yields from different platforms range from 10 3 to 10 5 vector genomes (vg) per cell, and there is an ongoing effort to improve vector yields in order to satisfy high product demands required for clinical trials and future commercialization.Crucial aspects of vector production include the molecular design of the rAAV-producing host cell line along with the design of AAV genes, promoters, and regulatory elements. Appropriately, configuring and balancing the expression of these elements not only contributes toward high productivity, it also improves process robustness and product quality. In this mini-review, the rational design of rAAV-producing expression systems is discussed, with special attention to molecular strategies that contribute to high-yielding, biomanufacturing-amenable rAAV production processes. Details on molecular optimization from four rAAV expression systems are covered: adenovirus, herpesvirus, and baculovirus complementation systems, as well as a recently explored yeast expression system.

Argonne National Laboratory, in cooperation with Los Alamos National Laboratory, is developing technology with NorthStar Medical Technologies to produce ⁹⁹Mo from the γ,n reaction on a ¹⁰⁰Mo target in an electron accelerator. During production runs and thermal testing of the helium-cooled target, it became obvious that a production-scale beam-line configuration would need a collimator to protect the target from accidental beam misplacement or a beam-profile change. A prototype high-power collimator and beam stop were designed and fabricated. Testing indicated that they will be able to operate at full power in the production-scale accelerator.

Full Text Available Environmental marketing (Eco-marketing, as a relatively new movement, emerged at the beginning of the 20th century, is in the growing phase of its development. Eco-labeling and other ways/types of eco-marketing are attracting more attention of consumers, since they are aware of the necessity of nature conservation and environmental protection. There has been a lot of misunderstanding and miss leadings in interpretation and substantiation of ecomarketing claims in previous period of time. One of the most concrete improvements in eco-marketing was appearance and establishment of ISO 14020 guidelines. ISO 14020 guidelines are integral part of ISO 14000 series of standards, which could be implemented in eco-marketing. At the same time, development of "green" products and marketing of "green" products, are direct positive contributions to resources reduction, environmental protection and sustainable economic development. Companies designing this kind of products can expect better position on the market, improvement of competitiveness, reduction of expenses (less raw materials, less waste, less harmful effects on the environment, raising corporate social responsibility, higher export.

Stegemann, Sven; Ternik, Robert L; Onder, Graziano; Khan, Mansoor A; van Riet-Nales, Diana A

2016-09-01

The term "patient centered," "patient centric," or "patient centricity" is increasingly used in the scientific literature in a wide variety of contexts. Generally, patient centric medicines are recognized as an essential contributor to healthy aging and the overall patient's quality of life and life expectancy. Besides the selection of the appropriate type of drug substance and strength for a particular indication in a particular patient, due attention must be paid that the pharmaceutical drug product design is also adequately addressing the particular patient's needs, i.e., assuring adequate patient adherence and the anticipate drug safety and effectiveness. Relevant pharmaceutical design aspects may e.g., involve the selection of the route of administration, the tablet size and shape, the ease of opening the package, the ability to read the user instruction, or the ability to follow the recommended (in-use) storage conditions. Currently, a harmonized definition on patient centric drug development/design has not yet been established. To stimulate scientific research and discussions and the consistent interpretation of test results, it is essential that such a definition is established. We have developed a first draft definition through various rounds of discussions within an interdisciplinary AAPS focus group of experts. This publication summarizes the outcomes and is intended to stimulate further discussions with all stakeholders towards a common definition of patient centric pharmaceutical drug product design that is useable across all disciplines involved.

A mathematical formulation for interface-based modular product design with geometric and weight constraints

Science.gov (United States)

Jung-Woon Yoo, John

2016-06-01

Since customer preferences change rapidly, there is a need for design processes with shorter product development cycles. Modularization plays a key role in achieving mass customization, which is crucial in today's competitive global market environments. Standardized interfaces among modularized parts have facilitated computational product design. To incorporate product size and weight constraints during computational design procedures, a mixed integer programming formulation is presented in this article. Product size and weight are two of the most important design parameters, as evidenced by recent smart-phone products. This article focuses on the integration of geometric, weight and interface constraints into the proposed mathematical formulation. The formulation generates the optimal selection of components for a target product, which satisfies geometric, weight and interface constraints. The formulation is verified through a case study and experiments are performed to demonstrate the performance of the formulation.

History of Nuclear Weapons Design and Production

Science.gov (United States)

Oelrich, Ivan

2007-04-01

The nuclear build-up of the United States and the Soviet Union during the Cold War is often portrayed as an arms race. Some part was indeed a bilateral competition, but much was the result of automatic application of technical advances as they became available, without careful consideration of strategic implications. Thus, the history of nuclear weapon design is partly designers responding to stated military needs and partly the world responding to constant innovations in nuclear capability. Today, plans for a new nuclear warhead are motivated primarily by the desire to maintain a nuclear design and production capability for the foreseeable future.

Incorporating ISO Metadata Using HDF Product Designer

Science.gov (United States)

Jelenak, Aleksandar; Kozimor, John; Habermann, Ted

2016-01-01

The need to store in HDF5 files increasing amounts of metadata of various complexity is greatly overcoming the capabilities of the Earth science metadata conventions currently in use. Data producers until now did not have much choice but to come up with ad hoc solutions to this challenge. Such solutions, in turn, pose a wide range of issues for data managers, distributors, and, ultimately, data users. The HDF Group is experimenting on a novel approach of using ISO 19115 metadata objects as a catch-all container for all the metadata that cannot be fitted into the current Earth science data conventions. This presentation will showcase how the HDF Product Designer software can be utilized to help data producers include various ISO metadata objects in their products.

Risk-Optimized Design of Production Systems by Use of GRAMOSA

Directory of Open Access Journals (Sweden)

Michael Lütjen

2014-01-01

Full Text Available Today production and logistic systems are getting more complex. This is a problem which the planning and design of such systems have to deal with. One main issue of production system development in series production is the planning of production processes and systems under uncertainty. New and existing production technologies are often not fully adoptable to new products. This is why some of the main characteristics, like, for example, cost, time, or quality, are not definable at the beginning. Only value ranges and probabilities can be estimated. However, the adaptation process is controllable, which means that the adaptation results are depending on the existing development budget and its resources. This paper presents an approach for the optimized allocation of development resources regarding the adaptation risks of production technologies and processes. The modeling concept GRAMOSA is used for integrated modeling and discrete event-based simulation of the aspired production system. To this end a domain-specific modeling language (DSML is applied. The further risk-based analysis of the simulation results and the optimized allocation of the development budget are done by use of mathematical optimization.

Research on knowledge support technology for product innovation design based on quality function knowledge deployment

Directory of Open Access Journals (Sweden)

Kai Zhang

2016-06-01

Full Text Available Based on the analysis of the relationship between the process of product innovation design and knowledge, this article proposes a theoretical model of quality function knowledge deployment. In order to link up the product innovation design and the knowledge required by the designer, the iterative method of quality function knowledge deployment is refined, as well as the knowledge retrieval model and knowledge support model based on quality function knowledge deployment are established. In the whole life cycle of product design, in view of the different requirements for knowledge in conceptual design stage, components’ configuration stage, process planning stage, and production planning stage, the quality function knowledge deployment model could link up the required knowledge with the engineering characteristics, component characteristics, process characteristics, and production characteristics in the four stages using the mapping relationship between the function characteristics and the knowledge and help the designer to track the required knowledge for realizing product innovation design. In this article, an instance about rewinding machine is given to demonstrate the practicability and validity of product innovation design knowledge support technology based on quality function knowledge deployment.

Design considerations for the commercial production of wood acrylics

International Nuclear Information System (INIS)

Witt, A.E.; Bosco, L.R.

1978-01-01

The major application of wood acrylics is for flooring, more specifically in high traffic area. The most important property is its abrasion resistance. As for the decisions in facility design, the following considerations must be made: irradiation or heat-catalyst to polymerize, machine irradiation or isotope irradiation, and wet or dry irradiation. Then, processing considerations are made on wood type, monomer selection, dye selection, fire retardant, dose conditions and crosslinker usage. In ''PermaGrain'' production, for example, the facility has the yearly production capacity of over 4,000,000 kilograms of wood acrylic. The starting wood form is small slats or fingers. After pressure cycle, the impregnant wet wood is lowered into an irradiation pool and the product canister passes around a cobalt 60 source. After irradiation, the product is taken out of the pool and allowed to cool. Then, final sizing and finishing are carried out. (Mori, K.)

When conducting a cost estimate there are many uncertainties. The aim with this study is therefore to explore how uncertainties regarding product cost can be consid...

Experimental on-line platform for product conceptual design: OpenDesigNet

Directory of Open Access Journals (Sweden)

Teresa Magal-Royo

2013-09-01

Full Text Available This paper highlights the need for using specialised on-line collaborative environments by designers and product engineers who increasingly use Web 2.0 technology to search for information. Although there are professional channels and networks, there is no specific platform which helps during a new product’s conceptualisation phase. Open communication must thus be promoted and encouraged amongst design professionals and companies to form working groups thereby allowing them to work collaboratively in the most open and creative phase of product design, i.e. conceptualisation. The OpenDesigNet (ODN experimental platform has been developed so that designers and small- or medium-sized companies (SMC can access on-line collaborative tools to support the creation and promotion of new on-line products and assess their immediate social impact. This article presents some of the results obtained during the validation phase involving a platform satisfaction survey of design engineering students and has led to a first-hand assessment of the new platform’s potential impact on their professional future.

Tumpal Pandiangan; Ign Djoko Irianto

2011-01-01

RGTT200K is a high temperature gas-cooled reactor (HTGR) which conceptually designed for power generation, hydrogen production and desalination. Hydrogen production process in this design uses thermochemical method of Iodine-Sulphur. To increase the thermal conversion efficiency in hydrogen production installations, it needs to design a thermal energy distribution and temperature associated with the process of thermo-chemical processes in the method of Iodine-Sulphur. In this method there are 7 kinds of processes: (i) H 2 SO4 decomposition reaction (ii) treatment of vaporization (iii) treatment of pre vaporizer (iv) treatment of flash 4 (v) treatment of decomposition of HI (vi) treatment of the flash 1-3 and (vii) Bunsen reaction. To regulate the distribution of energy and temperature appropriate to the needs of each process used 3 pieces of heat exchanger (HE). Calculation of energy distribution through the distribution of helium gas flow has been done with Scilab application programs, so that can know the distribution of thermal energy for production of 1 mole of hydrogen. From this model, it can calculate the thermal energy requirement for production of hydrogen at the desired capacity. In the conceptual design of RGTT200K, helium discharge has been designed by 20 kg/s, so that an efficient hydrogen production capacity needed to produce 15347.8 for 21.74 mole of H 2 . (author)

Product manufactured with short life cycle had only one major issue, it can lead to increasing volume of waste. Day by day, this untreated waste had consumed many landfill spaces, waiting for any possible alternatives. Lack of product recovery knowledge and recyclability features imprinted into product design are one of the main reason behind all this. Sustainable awareness aspect should not just be implied into people’s mind, but also onto product design. This paper presents a preliminary study on Kano model method in the conceptual design activities to improve product lifecycle. Kano model is a survey-type method, used to analyze and distinguished product qualities or features, also how the customers may have perceived them. Three important attributes of Kano model are performance, attractive and must-be. The proposed approach enables better understanding of customer requirements while providing a way for Kano model to be integrated into engineering design to improve product’s end-of-life. Further works will be continued to provide a better lifecycle option (increase percentage of reuse, remanufacture or recycle, whereby decrease percentage of waste) of a product using Kano model approach.

Green design for productivity, health and quality of life

Energy Technology Data Exchange (ETDEWEB)

2005-07-01

The potential cost-benefits for quality construction of office buildings were discussed with particular reference to sick building costs and health building gains. Cost-benefits were indicated in terms of first cost, operational energy costs, individual productivity, organizational productivity, health, attraction, taxation, and waste. The measures of human response in buildings were also discussed with reference to comfort and satisfaction, individual productivity, health and absenteeism, attraction, spatial flexibility, motivation and collaboration. The building attributes that have the greatest impact include air, light, thermal control, ergonomics, privacy and interaction, access to nature, land use and mobility. It was suggested that natural ventilation should be maximized with mixed-mode heating, ventilating and air conditioning (HVAC) systems, and that ventilation air should be separate from thermal conditioning. It was also suggested that temperature control can increase productivity and reduce energy consumption. Several international case studies have shown that acoustic privacy also increases individual productivity at complex tasks. The presentation concluded by indicating that healthy and sustainable design also depends on changing approaches to land use and community planning in terms of pedestrian walkways, maximized loading of infrastructure and buildings, minimized abandonment and green roof development to reduce annual cooling loads. tabs., figs.

1997-01-01

At a time when many companies are under pressure to reduce "times-to-market" the management of product information from the early stages of design through assembly to manufacture and production has become increasingly important. Similarly in the construction of high energy physics devices the collection of ( often evolving) engineering data is central to the subsequent physics analysis. Traditionally in industry design engineers have employed Engineering Data Management Systems ( also called Product Data Management Systems) to coordinate and control access to documented versions of product designs. However, these systems provide control only at the collaborative design level and are seldom used beyond design. Workflow management systems, on the other hand, are employed in industry to coordinate and support the more complex and repeatable work processes of the production environment. Commer cial workflow products cannot support the highly dynamic activities found both in the design stages of product developmen...

Implementation of quality by design toward processing of food products.

Science.gov (United States)

Rathore, Anurag S; Kapoor, Gautam

2017-05-28

Quality by design (QbD) is a systematic approach that begins with predefined objectives and emphasizes product and process understanding and process control. It is an approach based on principles of sound science and quality risk management. As the food processing industry continues to embrace the idea of in-line, online, and/or at-line sensors and real-time characterization for process monitoring and control, the existing gaps with regard to our ability to monitor multiple parameters/variables associated with the manufacturing process will be alleviated over time. Investments made for development of tools and approaches that facilitate high-throughput analytical and process development, process analytical technology, design of experiments, risk analysis, knowledge management, and enhancement of process/product understanding would pave way for operational and economic benefits later in the commercialization process and across other product pipelines. This article aims to achieve two major objectives. First, to review the progress that has been made in the recent years on the topic of QbD implementation in processing of food products and second, present a case study that illustrates benefits of such QbD implementation.

Systems metabolic engineering design: fatty acid production as an emerging case study.

Science.gov (United States)

Tee, Ting Wei; Chowdhury, Anupam; Maranas, Costas D; Shanks, Jacqueline V

2014-05-01

Increasing demand for petroleum has stimulated industry to develop sustainable production of chemicals and biofuels using microbial cell factories. Fatty acids of chain lengths from C6 to C16 are propitious intermediates for the catalytic synthesis of industrial chemicals and diesel-like biofuels. The abundance of genetic information available for Escherichia coli and specifically, fatty acid metabolism in E. coli, supports this bacterium as a promising host for engineering a biocatalyst for the microbial production of fatty acids. Recent successes rooted in different features of systems metabolic engineering in the strain design of high-yielding medium chain fatty acid producing E. coli strains provide an emerging case study of design methods for effective strain design. Classical metabolic engineering and synthetic biology approaches enabled different and distinct design paths towards a high-yielding strain. Here we highlight a rational strain design process in systems biology, an integrated computational and experimental approach for carboxylic acid production, as an alternative method. Additional challenges inherent in achieving an optimal strain for commercialization of medium chain-length fatty acids will likely require a collection of strategies from systems metabolic engineering. Not only will the continued advancement in systems metabolic engineering result in these highly productive strains more quickly, this knowledge will extend more rapidly the carboxylic acid platform to the microbial production of carboxylic acids with alternate chain-lengths and functionalities. © 2014 Wiley Periodicals, Inc.

2013-03-01

The philosophy of quality by design (QbD) is now leading the changes in the drug manufacturing mode from the conventional test-based approach to the science and risk based approach focusing on the detailed research and understanding of the production process. Along with the constant deepening of the understanding of the manufacturing process, the design space will be determined, and the emphasis of quality control will be shifted from the quality standards to the design space. Therefore, the establishment of the design space is core step in the implementation of QbD, and it is of great importance to study the methods for building the design space. This essay proposes the concept of design space for the production process of traditional Chinese medicine (TCM) preparations, gives a systematic introduction of the concept of the design space, analyzes the feasibility and significance to build the design space in the production process of traditional Chinese medicine preparations, and proposes study approaches on the basis of examples that comply with the characteristics of traditional Chinese medicine preparations, as well as future study orientations.

USE OF LEAN PRODUCTION INSTRUMENTS IN DESIGNING THE EDUCATIONAL PROCESS

Directory of Open Access Journals (Sweden)

Elietta P. Burnasheva

2016-03-01

Full Text Available Introduction: the concept of lean production seeks not a reduction of costs but complete elimination of losses that do not bring added value to the product or service. In any system, in all processes – from production and assembly, to hospitality, education, health, transport and social services – there are hidden losses. Teaching itself is a kind of production process in which a certain “product” (student acquires the added value (knowledge and skills, that is why it has become topical in educational institution to establish the working group on introduction of lean production into the learning process. The article presents the factors that are to be taken into account while designing the educational process based on the lean production principles. Materials and Methods: methods of analysis of existing system of vocational training in higher school, monitoring of the results of educational practice, modeling and experimental work in the process of analytical work were used. Results: important direction for eliminating losses in the educational process is the development of the interlinked curricula, allowing to avoid repeated study of a number of didactic units in the organization of continuous training in the system “Vocational education – Higher education”. In order to eliminate the possibility of incompetent graduate one should focus on the organisation of objective final control. Losses in education are caused by to the mismatch between labour market demand and the spectrum of areas of training in educational institutions. Discussion and Conclusions: the lean production possibilities are defined as instrumental in ensuring the organisation of “the process of lean learning”: by applying some lean production instruments such as the designing of the educational process, preventing of “faulty work” while training students, the attuning of the training system to employers’ requests, the visualisation of the education

POOR QUALITY OF PRODUCT DESIGN AS A CAUSE OF OCCUPATIONAL HEALTH HAZARDS: A CASE STUDY

Directory of Open Access Journals (Sweden)

Janko D. Jovanović

2007-12-01

Full Text Available Quality of product design, which is expected from manufacturers on world market these days, could be provided exclusively by integral approach to product design. Such approach aims to achievement of optimal design solution of product, which is in line with a number of requirements, conditions and limitations of functionality, technology, market and usage. Only those manufacturers who are able to provide such approach to product design have prospective on market. This paper deals with a case study of neglect of integral approach to product design and its consequencies, in order to spread awareness of necessity of its adoption. Scope of this case study is focused on bridge crane whose working vibrations are meant to be potential cause of occupational desease of spinal column of crane operator.

Fundamental framework toward optimal design of product platform for industrial three-axis linear-type robots

Directory of Open Access Journals (Sweden)

Kana Sawai

2015-07-01

Full Text Available This paper discusses an optimization-based approach for the design of a product platform for industrial three-axis linear-type robots, which are widely used for handling objects in manufacturing lines. Since the operational specifications of these robots, such as operation speed, working distance and orientation, weight and shape of loads, etc., will vary for different applications, robotic system vendors must provide various types of robots efficiently and effectively to meet a range of market needs. A promising step toward this goal is the concept of a product platform, in which several key elements are commonly used across a series of products, which can then be customized for individual requirements. However the design of a product platform is more complicated than that of each product, due to the need to optimize the design across many products. This paper proposes an optimization-based fundamental framework toward the design of a product platform for industrial three-axis linear-type robots; this framework allows the solution of a complicated design problem and builds an optimal design method of fundamental features of robot frames that are commonly used for a wide range of robots. In this formulation, some key performance metrics of the robot are estimated by a reduced-order model which is configured with beam theory. A multi-objective optimization problem is formulated to represent the trade-offs among key design parameters using a weighted-sum form for a single product. This formulation is integrated into a mini–max type optimization problem across a series of robots as an optimal design formulation for the product platform. Some case studies of optimal platform design for industrial three-axis linear-type robots are presented to demonstrate the applications of a genetic algorithm to such mathematical models.

2015-02-01

Full Text Available The paper deals with the issue covered by the field of industrial property, it deals with the right to designation, especially with characteristics of legal regulation of labeling of products with regard to their geographical origin at the Slovak, communitarian and international levels. Individual objects of the industrial property may be the result of intellectual creative activity of its creator/creators (e.g. inventions, utility models, designs or they are not the result of creative activity of a particular natural person and are considered as industrial property rights to designation. The group of rights to designation includes: business names, trademarks, designation of origin for products and geographical indications for products. The rights to designation, inter alia, shall ensure uniqueness and competitive advantage for entrepreneurs and easy identification on the market of goods and services for the consumers. The paper closely analyzes the harmonized legal regulation of designations of origin and geographical indications of agricultural products, foodstuffs, spirit drinks, and wines. At the example of Tokaj wine region, it demonstrates the importance of protected designations at the EU level, in case of which demonstrable geographical origin of the product with controlled product specification by authorized national bodies brings a guarantee of quality of this product for consumers and the competitive advantage during their commercial implementation for the entrepreneurs.

• Towards product design automation based on parameterized standard model with diversiform knowledge

  Science.gov (United States)

  Liu, Wei; Zhang, Xiaobing

  2017-04-01

  Product standardization based on CAD software is an effective way to improve design efficiency. In the past, research and development on standardization mainly focused on the level of component, and the standardization of the entire product as a whole is rarely taken into consideration. In this paper, the size and structure of 3D product models are both driven by the Excel datasheets, based on which a parameterized model library is therefore established. Diversiform knowledge including associated parameters and default properties are embedded into the templates in advance to simplify their reuse. Through the simple operation, we can obtain the correct product with the finished 3D models including single parts or complex assemblies. Two examples are illustrated later to invalid the idea, which will greatly improve the design efficiency.

• A regression-based Kansei engineering system based on form feature lines for product form design

  Directory of Open Access Journals (Sweden)

  Yan Xiong

  2016-06-01

  Full Text Available When developing new products, it is important for a designer to understand users’ perceptions and develop product form with the corresponding perceptions. In order to establish the mapping between users’ perceptions and product design features effectively, in this study, we presented a regression-based Kansei engineering system based on form feature lines for product form design. First according to the characteristics of design concept representation, product form features–product form feature lines were defined. Second, Kansei words were chosen to describe image perceptions toward product samples. Then, multiple linear regression and support vector regression were used to construct the models, respectively, that predicted users’ image perceptions. Using mobile phones as experimental samples, Kansei prediction models were established based on the front view form feature lines of the samples. From the experimental results, these two predict models were of good adaptability. But in contrast to multiple linear regression, the predict performance of support vector regression model was better, and support vector regression is more suitable for form regression prediction. The results of the case showed that the proposed method provided an effective means for designers to manipulate product features as a whole, and it can optimize Kansei model and improve practical values.

• An Optimization Model for Product Placement on Product Listing Pages

  Directory of Open Access Journals (Sweden)

  Yan-Kwang Chen

  2014-01-01

  Full Text Available The design of product listing pages is a key component of Website design because it has significant influence on the sales volume on a Website. This study focuses on product placement in designing product listing pages. Product placement concerns how venders of online stores place their products over the product listing pages for maximization of profit. This problem is very similar to the offline shelf management problem. Since product information sources on a Web page are typically communicated through the text and image, visual stimuli such as color, shape, size, and spatial arrangement often have an effect on the visual attention of online shoppers and, in turn, influence their eventual purchase decisions. In view of the above, this study synthesizes the visual attention literature and theory of shelf-space allocation to develop a mathematical programming model with genetic algorithms for finding optimal solutions to the focused issue. The validity of the model is illustrated with example problems.

• Creativity in ergonomic design: a supplemental value-adding source for product and service development.

  Science.gov (United States)

  Zeng, Liang; Proctor, Robert W; Salvendy, Gavriel

  2010-08-01

  This article investigates the role of creativity in ergonomic design and the generic process of developing creative products and services. Creativity is gaining increased emphasis in both academia and industry. More than 50 years of research in creativity indicates that creativity is key to product and service innovation. Nevertheless, there is scarcely any comprehensive review dedicated to appraising the complex construct of creativity, the underlying cognitive process, and the role of creativity in product and service development. We review relevant literature regarding creativity, creative cognition, and the engineering design process to appraise the role of creativity in ergonomic design and to construct a conceptual model of creative product and service development. A framework of ergodesign creativity is advanced that highlights the central role of creativity in synergistically addressing the four dimensions of ergonomic design: functionality, safety, usability, and affectivity. A conceptual model of creative design process is then constructed that is goal oriented and is initiated by active problem finding and problem formulating. This process is carried out in a recursive and dynamic way, facilitated by creative thinking strategies. It is proposed that ergodesign creativity can add supplemental value to products and services, which subsequently affects consumer behavior and helps organizations gain competitive advantage. The proposed conceptual framework of ergodesign creativity and creative design process can serve as the ground for future theory development. Propositions advanced in this study should facilitate designers generating products and services that are creative and commercially competitive.

• The European space suit, a design for productivity and crew safety

  Science.gov (United States)

  Skoog, A. Ingemar; Berthier, S.; Ollivier, Y.

  In order to fulfil the two major mission objectives, i.e. support planned and unplanned external servicing of the COLUMBUS FFL and support the HERMES vehicle for safety critical operations and emergencies, the European Space Suit System baseline configuration incorporates a number of design features, which shall enhance the productivity and the crew safety of EVA astronauts. The work in EVA is today - and will be for several years - a manual work. Consequently, to improve productivity, the first challenge is to design a suit enclosure which minimizes movement restrictions and crew fatigue. It is covered by the "ergonomic" aspect of the suit design. Furthermore, it is also necessary to help the EVA crewmember in his work, by giving him the right information at the right time. Many solutions exist in this field of Man-Machine Interface, from a very simple system, based on cuff check lists, up to advanced systems, including Head-Up Displays. The design concept for improved productivity encompasses following features: • easy donning/doffing thru rear entry, • suit ergonomy optimisation, • display of operational information in alpha-numerical and graphical from, and • voice processing for operations and safety critical information. Concerning crew safety the major design features are: • a lower R-factor for emergency EVA operations thru incressed suit pressure, • zero prebreath conditions for normal operations, • visual and voice processing of all safety critical functions, and • an autonomous life support system to permit unrestricted operations around HERMES and the CFFL. The paper analyses crew safety and productivity criteria and describes how these features are being built into the design of the European Space Suit System.

• Product and service design for patient centered diabetes care

  Directory of Open Access Journals (Sweden)

  Soumitri Varadarajan

  2009-11-01

  Full Text Available Design plays a marginal part in the discourse of diabetes care, mainly in visualizing the form and packaging of medical technologies. The authors however have a practice that advocates that design orientated solutions can add much needed dimensions to problems that havetraditionally been the exclusive preserve of expert discourses. This position has for long been a validated and largely accepted approach in design’s engagement withissues in sustainability and development studies. A similar approach in the area of medicine has been constructed bythe authors and marks out a position of advocacy where the designer takes on agency to intervene on behalf of the user community. This position contains a healthy critique of thetraditional approach of product design for manufacture while simultaneously amplifying a desire to intervene and make a substantial improvement in the quality of life ofpeople with diabetes. This article first opens out contemporary diabetes care as a contested domain and then goes on to sketch out the key aspects of a design practice focussed upon delivering positive health outcomes in diabetes care. The specific context of discussion for this article is the practice of teaching in design studios wherestudents of design listen to the voices of people with diabetes and visualize ways for design to provide products and service solutions that transform the lived experiences of people with diabetes.

Design and construction of a photobioreactor for hydrogen production, including status in the field.

Science.gov (United States)

Skjånes, Kari; Andersen, Uno; Heidorn, Thorsten; Borgvang, Stig A

Several species of microalgae and phototrophic bacteria are able to produce hydrogen under certain conditions. A range of different photobioreactor systems have been used by different research groups for lab-scale hydrogen production experiments, and some few attempts have been made to upscale the hydrogen production process. Even though a photobioreactor system for hydrogen production does require special construction properties (e.g., hydrogen tight, mixing by other means than bubbling with air), only very few attempts have been made to design photobioreactors specifically for the purpose of hydrogen production. We have constructed a flat panel photobioreactor system that can be used in two modes: either for the cultivation of phototrophic microorganisms (upright and bubbling) or for the production of hydrogen or other anaerobic products (mixing by "rocking motion"). Special emphasis has been taken to avoid any hydrogen leakages, both by means of constructional and material choices. The flat plate photobioreactor system is controlled by a custom-built control system that can log and control temperature, pH, and optical density and additionally log the amount of produced gas and dissolved oxygen concentration. This paper summarizes the status in the field of photobioreactors for hydrogen production and describes in detail the design and construction of a purpose-built flat panel photobioreactor system, optimized for hydrogen production in terms of structural functionality, durability, performance, and selection of materials. The motivations for the choices made during the design process and advantages/disadvantages of previous designs are discussed.

Exploring Advertising and Product Design Sexual Implications: A Sociocultural Approach

Directory of Open Access Journals (Sweden)

Johannis Tsoumas

2016-07-01

Full Text Available This paper explores design thought and application on various fields of its domain, under the prism of the human sexuality. However the two main areas of our concern are the fields of advertising and product design which, according to the author, represent the most significant parts on which the concept of human sexuality is thoroughly applied and still remains effective. Designing under this instinctive human value, one can easily trace the importance of concepts such as charm and pleasure, which can overlap and possibly ‘beat to death’ the concepts of usability and quality of use, in many ways. The starting point of this allegory in handling and promoting new products, most of which are not directly connected with the sense of sexuality, are the advertisements. On the other hand, one will be able to find out the myth of gender and its contradictions in a certain group of products which have direct sexuality references and most of them are designed for a limited, however faithful and increasingly concerned consumer group. Thirdly, the author aims to focus on the ‘discovery’ of socially marginalized consumer groups, such as the homosexual community, by some inventive entrepreneurs and designers, for the formation of a ‘new market’ which seems to thrive in terms of profit. As this, meteoric rise, market is directly connected with analogous social changes globally, one will be able to understand its development, but also the exploitation of homosexual behaviour, via the ideological points of both sides: designers and consumers.

Nuclear hydrogen production is necessary in an anticipated hydrogen society that demands a massive quantity of hydrogen without economic disadvantage. Japan Atomic Energy Agency (JAEA) has launched the conceptual design study of a hydrogen production system with a near-term plan to connect it to Japan's first high-temperature gas-cooled reactor HTTR. The candidate hydrogen production system is based on the thermochemical water-splitting iodine sulphur (IS) process.The heat of 10 MWth at approximately 900degC, which can be provided by the secondary helium from the intermediate heat exchanger of the HTTR, is the energy input to the hydrogen production system. In this paper, we describe the recent progresses made in the conceptual design of advanced process heat exchangers of the HTTR-IS hydrogen production system. A new concept of sulphuric acid decomposer is proposed. This involves the integration of three separate functions of sulphuric acid decomposer, sulphur trioxide decomposer, and process heat exchanger. A new mixer-settler type of Bunsen reactor is also designed. This integrates three separate functions of Bunsen reactor, phase separator, and pump. The new concepts are expected to result in improved economics through construction and operation cost reductions because the number of process equipment and complicated connections between the equipment has been substantially reduced.

study is used to demonstrate how the monitoring system can be used to efficiently guide corrective action to improve product performance. It is claimed that the monitoring system can be used to dramatically cut the time taken to identify, planand execute corrective action related to typical quality......In the current quality paradigm, the performance of a product is kept within specification by ensuring that its parts are within specification. Product performance is then validated after final assembly. However, this does not control how robust the product performance is, i.e. how much...... it will vary between the specification limits. In this paper, a model for predicting product performance is proposed, taking into account design, assembly and process parameters live from production. This empowers production to maintain final product performance, instead of part quality. The PRECI‐IN case...

Metal casting company produces machinery spare part for manufactures. One of the product produced is dust filter. Most of palm oil mill used this product. Since it is used in most of palm oil mill, company often have problems to address this product. One of problem is the disordered of production process. It carried out by the job sequencing. The important job that should be solved first, least implement, while less important job and could be completed later, implemented first. Design Structure Matrix (DSM) used to analyse and determine priorities in the production process. DSM analysis is sort of production process through dependency sequencing. The result of dependency sequences shows the sequence process according to the inter-process linkage considering before and after activities. Finally, it demonstrates their activities to the coupled activities for metal smelting, refining, grinding, cutting container castings, metal expenditure of molds, metal casting, coating processes, and manufacture of molds of sand.

IDENTIFYING PRODUCT AND PRICE STRATEGIES FOR DESIGNING TRANSACTIONAL BANKING PACKAGES ADDRESSED TO SMES (CONSIDERATIONS

Directory of Open Access Journals (Sweden)

Giuca Simona-Mihaela

2014-07-01

Full Text Available The current paper has the aim to provide guidelines for designing efficient product and price strategies, through proposed business cases which could be used especially for banking products addressed to SMEs. While identifying the optimal product and price strategy and designing the product catalogue structure, the marketing specialist should definitely consider existing portfolio behaviour and estimate the growing potential (if possible, overall portfolio, with focus on accurately defining the additional impact of the newly proposed product/ products. A business case contains estimations for results to be generated by products to be launched or optimized. This paper presents complex schemes for business case scenarios for migration of existing portfolio to the new products, but also considers new clients acquisition based on important features of the products. The pricing strategy is not a simple task to manage. Especially when speaking about transactional packages (for which the price is lower than separate services included, some segments or clusters may generate loss to the bank if they already used the services at a higher price than the one of the package. Therefore, the decision of setting up specific prices needs to be based on an accurate and complex analysis, as presented in current paper. The assumptions used in a business case need to be relevant for the entire process of designing and launching a product, therefore they can always be adjusted for better calculation of the impact. No matter if the assumptions and prices remain as in the initial proposal or not, the steps to be followed are the same. Segmentation also plays an important role in designing the product strategy, since the target for a product or product catalogue can be represented by a segment, a sub segment or a cluster of many segments. Not always the initial segmentation represents the clustering for the product strategy. Sometimes, behaviour of existing clients

A cyclotron isotope production facility designed to maximize production and minimize radiation dose

Continuing increases in requirements from the nuclear medicine industry for cyclotron isotopes is increasing the demands being put on an aging stock of machines. In addition, with the 1990 recommendations of the ICRP publication in place, strict dose limits will be required and this will have an effect on the way these machines are being operated. Recent advances in cyclotron design combined with lessons learned from two decades of commercial production mean that new facilities can result in a substantial charge on target, low personnel dose, and minimal residual activation. An optimal facility would utilize a well engineered variable energy/high current H - cyclotron design, multiple beam extraction, and individual target caves. Materials would be selected to minimize activation and absorb neutrons. Equipment would be designed to minimize maintenance activities performed in high radiation fields. (orig.)

Vanillin is one of the most widely used flavouring agents, originally obtained from cured seed pods of the vanilla orchid Vanilla planifolia. Currently vanillin is mostly produced via chemical synthesis. A de novo synthetic pathway for heterologous vanillin production from glucose has recently been implemented in baker's yeast, Saccharamyces cerevisiae. In this study we aimed at engineering this vanillin cell factory towards improved productivity and thereby at developing an attractive alternative to chemical synthesis. Expression of a glycosyltransferase from Arabidopsis thaliana in the vanillin producing S. cerevisiae strain served to decrease product toxicity. An in silico metabolic engineering strategy of this vanillin glucoside producing strain was designed using a set of stoichiometric modelling tools applied to the yeast genome-scale metabolic network. Two targets (PDC1 and GDH1) were selected for experimental verification resulting in four engineered strains. Three of the mutants showed up to 1.5 fold higher vanillin β-D-glucoside yield in batch mode, while continuous culture of the Δpdc1 mutant showed a 2-fold productivity improvement. This mutant presented a 5-fold improvement in free vanillin production compared to the previous work on de novo vanillin biosynthesis in baker's yeast. Use of constraints corresponding to different physiological states was found to greatly influence the target predictions given minimization of metabolic adjustment (MOMA) as biological objective function. In vivo verification of the targets, selected based on their predicted metabolic adjustment, successfully led to overproducing strains. Overall, we propose and demonstrate a framework for in silico design and target selection for improving microbial cell factories.

Verifying Architectural Design Rules of the Flight Software Product Line

Ganesan, Dharmalingam; Lindvall, Mikael; Ackermann, Chris; McComas, David; Bartholomew, Maureen

2009-01-01

This paper presents experiences of verifying architectural design rules of the NASA Core Flight Software (CFS) product line implementation. The goal of the verification is to check whether the implementation is consistent with the CFS architectural rules derived from the developer's guide. The results indicate that consistency checking helps a) identifying architecturally significant deviations that were eluded during code reviews, b) clarifying the design rules to the team, and c) assessing the overall implementation quality. Furthermore, it helps connecting business goals to architectural principles, and to the implementation. This paper is the first step in the definition of a method for analyzing and evaluating product line implementations from an architecture-centric perspective.

Choosing Beauty and Feeling Good: How Attractive Product Design Increases Self-Affirmation

Directory of Open Access Journals (Sweden)

Townsend Claudia

2015-11-01

Full Text Available Consumers construct and maintain self-concepts through the use of branded consumer products. Yet product choice not only reflects an actual or desired image of the self but can also directly influence a person’s sense of self and even boost self-esteem. The aesthetics of a product is an attribute that has the power to transform how consumers perceive themselves. The mere act of choosing a beautiful product over a less good-looking one affirms people’s sense of self - who they are and what their values are. It goes beyond personal image building and self-presentation; its impact is also turned inwards. Choice of high design works as a unique form of affirmation. It works unconsciously, and high design may even be a particularly powerful form of affirmation precisely because its relationship to the self and one’s values is not obvious. And design is more powerful than other features in this respect. Comfort and ease of use, taste and brand do not have the same self-affirming quality as design. It is not simply that “treating” oneself or going for the pleasurable option has an affirming effect; it is specific to the choice of aesthetics.

Energy Productivity of the High Velocity Algae Raceway Integrated Design (ARID-HV)

Energy Technology Data Exchange (ETDEWEB)

Attalah, Said; Waller, Peter M.; Khawam, George; Ryan, Randy D.; Huesemann, Michael H.

2015-06-03

The original Algae Raceway Integrated Design (ARID) raceway was an effective method to increase algae culture temperature in open raceways. However, the energy input was high and flow mixing was poor. Thus, the High Velocity Algae Raceway Integrated Design (ARID-HV) raceway was developed to reduce energy input requirements and improve flow mixing in a serpentine flow path. A prototype ARID-HV system was installed in Tucson, Arizona. Based on algae growth simulation and hydraulic analysis, an optimal ARID-HV raceway was designed, and the electrical energy input requirement (kWh ha-1 d-1) was calculated. An algae growth model was used to compare the productivity of ARIDHV and conventional raceways. The model uses a pond surface energy balance to calculate water temperature as a function of environmental parameters. Algae growth and biomass loss are calculated based on rate constants during day and night, respectively. A 10 year simulation of DOE strain 1412 (Chlorella sorokiniana) showed that the ARID-HV raceway had significantly higher production than a conventional raceway for all months of the year in Tucson, Arizona. It should be noted that this difference is species and climate specific and is not observed in other climates and with other algae species. The algae growth model results and electrical energy input evaluation were used to compare the energy productivity (algae production rate/energy input) of the ARID-HV and conventional raceways for Chlorella sorokiniana in Tucson, Arizona. The energy productivity of the ARID-HV raceway was significantly greater than the energy productivity of a conventional raceway for all months of the year.

Productivity and energy efficiency

Energy Technology Data Exchange (ETDEWEB)

Lovins, H. [Rocky Mountain Inst., Snowmass, CO (United States)

1995-12-31

Energy efficient building and office design offers the possibility of significantly increased worker productivity. By improving lighting, heating and cooling, workers can be made more comfortable and productive. An increase of 1 percent in productivity can provide savings to a company that exceed its entire energy bill. Efficient design practices are cost effective just from their energy savings. The resulting productivity gains make them indispensable. This paper documents eight cases in which efficient lighting, heating, and cooling have measurably increased worker productivity, decreased absenteeism, and/or improved the quality of work performed. They also show that efficient lighting can measurably increase work quality by removing errors and manufacturing defects. The case studies presented include retrofit of existing buildings and the design of new facilities, and cover a variety of commercial and industrial settings. Each case study identifies the design changes that were most responsible for increased productivity. As the eight case studies illustrate, energy efficient design may be one of the least expensive ways for a business to improve the productivity of its workers and the quality of its product.

Development of the design of standardized units for the production of artificial radionuclides

International Nuclear Information System (INIS)

Auger, J.P.

1976-01-01

The production of artificial radionuclides began more than 20 years ago and has seen continuous growth at the rate over 20% a year. Technology has had to be adapted constantly to this growth in order to guarantee production and at the same time ensure the safety of personnel. The Department, which started its career in underground workings at Chatillon and then moved to the Saclay hot laboratories, is now housed in a building designed specially for the production of artificial radionuclides and equipped with standard production units. The first generation of standard units was sufficient to handle production which had begun to grow. Subsequently, thanks to the experience gained, there came into being a second generation of standardized units perfectly adapted to the new production requirements. The paper describes the evolution of design solutions between the first and the second standard, relating to contained cells, cell containment, remote control, interchangeability of cells, ventilation, waste discharge systems and repair of internal equipment. A highly positive evaluation can be made of the experience gained from the present standard. (author)

An analysis of the benefits of ethnography design methods for product modelling

Science.gov (United States)

Butlewski, M.; Misztal, A.; Belu, N.

2016-08-01

The essence of modelling is to reflect the studied piece of reality in such a way that best describes the selected elements of the designed system. A model is used in design to optimize the structure and parameters of the constructed object and is a tool for assessing the quality of construction, eliminating weak links and ensuring adequate safety components. In view of the aim of modelling, it can be divided into functional modelling, showing the complexity of the object, and reliability modelling, specifying its states at variable threshold values. In design, modelling allows for significant savings in resources that would otherwise be spent because of problems appearing at the prototype stage, but also during production or in the course of using the product. In the practice of ergonomic design many problems could be avoided if early enough in the design process the values of parameters and their relations would be taken into account through modelling. On the other hand, the modelling process can be costly and time-consuming to carry out, and against the currently pervasive lean production it is a highly undesirable factor. Therefore, the modelling process should be supported with the use of appropriate cognitive techniques namely ethnography design, which would determine inadequacies of existing models as well as indicate the equivalent conditions for modelling. The justification of the use of this technique results both from the possibility of providing additional information, as well as the opportunity to “test” the phenomena affecting the design process. Ergonomic modelling tests developed solutions towards their adaptation to users’ anthropometric, biomechanical and psychomotor characteristics, as well as behaviour patterns. However, knowledge of the latter and achieving a sufficient ergonomic and functional quality of proposed solutions often requires the use of the ethnography design approach. The aim of this article is to test the practical

A methodological approach for designing and sequencing product families in Reconfigurable Disassembly Systems

Directory of Open Access Journals (Sweden)

Ignacio Eguia

2011-10-01

Full Text Available Purpose: A Reconfigurable Disassembly System (RDS represents a new paradigm of automated disassembly system that uses reconfigurable manufacturing technology for fast adaptation to changes in the quantity and mix of products to disassemble. This paper deals with a methodology for designing and sequencing product families in RDS. Design/methodology/approach: The methodology is developed in a two-phase approach, where products are first grouped into families and then families are sequenced through the RDS, computing the required machines and modules configuration for each family. Products are grouped into families based on their common features using a Hierarchical Clustering Algorithm. The optimal sequence of the product families is calculated using a Mixed-Integer Linear Programming model minimizing reconfigurability and operational costs. Findings: This paper is focused to enable reconfigurable manufacturing technologies to attain some degree of adaptability during disassembly automation design using modular machine tools. Research limitations/implications: The MILP model proposed for the second phase is similar to the well-known Travelling Salesman Problem (TSP and therefore its complexity grows exponentially with the number of products to disassemble. In real-world problems, which a higher number of products, it may be advisable to solve the model approximately with heuristics. Practical implications: The importance of industrial recycling and remanufacturing is growing due to increasing environmental and economic pressures. Disassembly is an important part of remanufacturing systems for reuse and recycling purposes. Automatic disassembly techniques have a growing number of applications in the area of electronics, aerospace, construction and industrial equipment. In this paper, a design and scheduling approach is proposed to apply in this area. Originality/value: This paper presents a new concept called Reconfigurable Disassembly System

Reprint of Design of synthetic microbial communities for biotechnological production processes.

Science.gov (United States)

Jagmann, Nina; Philipp, Bodo

2014-12-20

In their natural habitats microorganisms live in multi-species communities, in which the community members exhibit complex metabolic interactions. In contrast, biotechnological production processes catalyzed by microorganisms are usually carried out with single strains in pure cultures. A number of production processes, however, may be more efficiently catalyzed by the concerted action of microbial communities. This review will give an overview of organismic interactions between microbial cells and of biotechnological applications of microbial communities. It focuses on synthetic microbial communities that consist of microorganisms that have been genetically engineered. Design principles for such synthetic communities will be exemplified based on plausible scenarios for biotechnological production processes. These design principles comprise interspecific metabolic interactions via cross-feeding, regulation by interspecific signaling processes via metabolites and autoinducing signal molecules, and spatial structuring of synthetic microbial communities. In particular, the implementation of metabolic interdependencies, of positive feedback regulation and of inducible cell aggregation and biofilm formation will be outlined. Synthetic microbial communities constitute a viable extension of the biotechnological application of metabolically engineered single strains and enlarge the scope of microbial production processes.
