The CWE is a platform that allows geographically dispersed team members to collaborate over the Internet to conduct the total furniture design process. Resources such as: design data, product simulation models, materials, marketing information, client’s requirements etc. are integrated into the CWE and shared with all the participants within the total furniture design process. In the construction of the infrastructure of the CWE, secondary development of CAD tools is used to control and modify parametrically the product sample models, as well as picking up the internal design data of the cad tools to store it into the external relational database to allow access to other participants. Multiple types of data stored in the database are structured in order to be easily accessible and searchable. Extensible Markup Language (XML) and its applications, are adopted as neutral file formats, thus allowing different CAD data to inter-translate in a convenient and safe manner. An example of this is Scalable Vector Graphic (SVG), which is used for 2D engineering drawings. Web services are the core technology which enables distributed and cross-platform resources to be shared as services. 3D models of furniture can be viewed and navigated in the integrated virtual environments based on Extensible 3D (X3D)

A lifecycle assessment approach has been utilized throughout the total design process of the green lighting product. In this paper, the sustainable design through the product lifecycle is presented first, then prototype of the product and the LCA conducted using a software package are given, followed by testing results, which prove the successful development of the product

The global lighting market is expected to have over 100 billion euros’ revenue by 2020 (McKinsey & Company 2012), and the introduction of Light Emitting Diode (LED) technology in the lighting sector is leading to a rapid growth of LED-based lighting products. By 2020, it is predicted that the LED-based lighting market share will be almost 70% of the total lighting market (McKinsey & Company 2012). However, lighting products also cause a negative impact on the environment during all the product life cycle stages, especially during the use stage. To date, there are no in-depth studies that have researched how to reduce the environmental impact caused by LED-based lighting products; therefore, research in this area is needed. This research aims to contribute to the body of knowledge in this area by studying the following issues: 1) What the key product-related features are that influence the environmental impact of LED-based l...

This is mainly the result of a lack of a widely agreed and recognized definitions’ framework of these types of disciplines and their research methods and outcomes. This paper will begin by attempting to define: Design, design-based disciplines, and industrial design in particular; then it will carry on defining and comparing their specific and currently used research methods and outcomes (supported by examples of past research projects), in order to illustrate their differences in relation to industrial design research. Finally, all this information will be synthesised in a generic definitions’ framework of similar design-based disciplines. The final aim of this framework will be to be used as a reference for academics (researchers/educators) and professionals (design practitioners) in industrial design, in order to help them to differentiate between similar design-based disciplines and their research methods and outcomes, for academic (evaluation) and professional (designers’ roles) purposes

To meet such a demand, a toolbox for design and manufacture of LED lighting products has been developed. In this paper, the demand for the types of tools suitable for the toolbox is discussed first, which is based on semi-structured survey results. The toolbox content and the integration of the tools into the LED product development process are then presented. The description of the integration is focused on computer aided tools, due to the restriction on the length of this paper. A case study is provided to illustrate the integration process.

Designers play a vital role in resolving this problem -their decisions affect product manufacturing, distribution, use, and disposal -and hence they must be aware of the positive and negative impacts of their design decisions. Sustainable product design education is key to developing the knowledge, skills, and responsibility required for future generations of product designers and their educators to make informed and responsible decisions within their practice, and also enhance the social and environmental performance of their creations and effectively communicate the value of such decisions within a commercial context. In this article, we present insights and challenges in contemporary sustainable product design education in higher education. We document the experiences of six academics involved in teaching and researching sustainable product design in the United Kingdom, Australia, Denmark, the Netherlands, and the United States. We hope to provide a useful reference for academics seeking to adopt sustainable product design practices in their existing programs, develop new sustainable product design education programs, or reflect on their own existing product design practice.

However, these have not been implemented and adopted by industry as much as they should. A better understanding of real-world industrial eco-design and development processes, and the eco-design tools applied during these, could inform the development of more effective and applicable eco-design methods and tools, for generic as well as for specific product categories (e.g., LED lighting products). This paper addresses this issue by describing and examining a real-world process followed to design and develop a LED lighting product by a lighting manufacturer, via case study research. The case study involved direct participatory observation to gather the data and provided new insights about the stages of the design and development process, as well as the tools applied, which were examined and discussed to inform the improvement of existing methods and tools, or the development of be...

The paper discusses the benefits and the practicality of using human-power as a domestic energy source to power electrical and electronic devices and explores the benefit of its use in a more diverse perspective for possible change in behaviour and energy savings for improved sustainability in the society. The economic and sustainability gains of using Human-Powered Products (HPPs) are investigated. Two studies have been conducted, the first is a study which involves assessing the environmental impact of a human-powered products via Life Cycle Assessment (LCA); and the second is a case study called Home User Study (HUS), where the technology is experimentally tested. The humanpowered system is used to explore the real benefits and life-cycle analysis towards assessing the sustainability of such products. The Home User Study (HUS) has been conducted to explore the in-situ use of human-powered systems using a new prototype that has been built and deployed. The study has used a monitoring device to measure the outcome of the interaction between the user and human-powered products. The results interestingly have revealed various other forms of benefits beyond renewable energy that could add extra motives for using human-powered products, such as health benefits. The paper also puts an emphasis on the opportunity of using Human-Powered Products which can be perceived as a great viable solution against counter measuring social issues such as physical inactivity and increasing sedentary behaviour. The results of the theoretical study indicate that Human-Powered Products (HPP) do not offer significant financial savings. The results of the HUS indicate that using human-powered products for health prospective outweigh the benefit gained from the prospective of energy savings and renewable energy. Based on the findings of this study, the paper suggests an approach that shows how the implementation of Human-powered systems could provide the opportunity to 2 sustainable energy generation and energy savings, but in all cases they can be retained through a motivational drive in improving the health benefit via encouraging physical activities.

Although there are tools and methods available for reducing the environmental impact of lighting products, it is a challenging task to integrate them throughout the product development process. To overcome the challenge, this research developed an approach to integrate tools/methods relevant for the eco-design through product development process to reduce the environmental impact of lighting products. Six types of methods, such module design, and 30 tools, such as lifecycle assessment software packages, are considered in the integrated approach. The product specification with eco-constrains is established for implementation at each design stage to ensure the product eco-features. The approach was applied in the development of an LED table lamp which was then assessed in comparison with a benchmark LED lamp regarding environmental lifecycle impact and lighting...

This is illustrated using a real-life example, where the environmental impact of a lighting product manufactured by a lighting manufacturer is assessed with Simapro (LCA-based software). After the illustration, the limitations of LCA are discussed.

Product designers and manufacturers have to be aware of these, because some of these are mandatory in some countries (e.g. EU countries) and others can contribute significantly to reduce the environmental and social impact of products, thus making the products more sustainable. The chapter begins by providing a general introduction about regulations, directives and standards and their importance. It then continues with a description of the main directives, regulations and standards that are relevant to sustainable design and manufacturing. Finally it is explained how directives, regulations and standards are applied in design and development processes.

One of the most effective and feasible approaches to reduce their environmental impact is eco-design. However, there are not comprehensive and updated systematic methods to eco-design lighting products. This chapter presents an effective comprehensive eco-design integrated approach to design lighting products. The approach integrates eco-design guidelines, life cycle assessment, finite element analysis, lighting driver selector and experimental methods into the product development process. The approach is demonstrated with a case study based on the design of a luminaire with low environmental impact produced by a lighting manufacturer. The advantages and disadvantages of the methods/tools involved in the approach are discussed. This approach contributes to the body of knowledge in the area of methods and tools to support designers to design lighting products with lower envi...
