The approach consists of numerical analysis and three-dimensional simulation within an advanced CAE package. The numerical analysis secures the localised contact, which provides mathematical models and a numerical calculation procedure to determine the modification parameters for the PLTC. With the three-dimensional simulation, the tooth contact pattern at any instant and the moving direction of the localised contact area can be predicted; moreover, the interference between the modified tooth surfaces can be detected, and, hence, it can be avoided at design stage. The simulation proves that the PLTC is much less sensitive to the errors arising from manufacturing and assembly, which is beneficial for achieving a high transmission quality and cutting down the time and efforts spent in production and assembly.

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...

To incentivise consumers’ recycling/reusing behaviours and enhance their environmental awareness, a novel ICT-based system for recycling and eco-shopping has been developed in this paper. The recycling of EoL products is conducted based on information-communication technologies to remotely monitor and manage the recycled products (such as electronics or household bio-wastes), enabling consumers’ recycling process over the Internet. Consumers are awarded the eco-credits, which can be used for various forms of eco-incentives, such as shopping discounts, tree planting donations, and exchanges for theatre and museum tickets. The eco-costs reflect the environmental impact of a product throughout its life cycle. The consumer is informed about the eco-costs through eco-shopping, which are displayed on a payment receipt. Both ...

Overview of this book is given with brief information of the 16 chapters. The scope of sustainable product development is presented. The sustainable product development process is detailed with explanation of the sustainable product development through the product lifecycle and its objective, as well as a three-tiers approach for sustainable product design. The integration of methods and tools through the product development process is described, and all the tools and methods presented in other chapters of this book are relevant to this integrated approach. At the end, the novel contributions of this book are highlighted.

This research conducted a structured review addressing sustainable product innovation, including sustainable product development and service, environmental and socio-economic impacts, communication of the sustainable product innovation to consumers via ecolabelling and declarations, and sustainability benchmarking. The review revealed that current research in sustainable product development and service focuses more on environmental and economic aspects, but the social aspect has not been given enough attention, and the interconnection between product development and service needs to be further addressed. Systematic sustainable innovation, considering the whole life cycle of the product to control and improve overall sustainability in the early product development stages should be paid more attention. To overcome the gaps, a framewor...

The ecological impact of a product can be measured with a numerical value called eco-point (EU H2020 CIRC4Life Project 2018), eco-score or eco-cost (von Geibler 2014). In this book, the ‘eco-point’ is used as a reference of the ecological impact values of products. In addition to the ‘eco-point’, the eco-point approach presented in this chapter also includes ‘eco-debit’ to show the customer’s negative ecological impact resulted from the products purchased, ‘eco-credit’ to credit customers’ positive behaviour of recycling end-of-life products, ‘eco-shopping’ for consumers to gain the ecological information of the products to be purchased, and ‘consumer eco-account’ to record consumers’ ecological footprints. The eco-accounting (or ‘ecological accounting’) infrastructure presented in this chapter includes the eco-point approach and the implementation of the eco-points, eco-debits and eco-credits, and their applications in sustainable production, eco-shopping, recycle/reuse and consumer eco-accounts. In this chapter, the eco-point approach is presented first, followed by the presentation of eco-accounting framework. To implement the eco-accounting framework requires large amount of dynamic data processing and management, and various information technologies, which are further presented in Chap. 6.

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...

Thus, integration of tools, methods, techniques for sustainability into design processes is becoming essential to design greener products. This paper presents a novel environmental impact assessment of lighting products’ conducted at the design stage, with the support of Life Cycle Assessment methods and related tools including Software Simapro. Two lighting products are used in the assessment, the results showed that one of the lighting products had less (total) impact on the environment than the other one, the main difference of impact between both products was located at the manufacturing phase, and their transport and use phases have higher impact within the life-cycle of the products.

In this paper, the related concept and eco-incentive scheme are introduced first; the infrastructure of the mobile application system is presented; and the process of system development is detailed. The mobile system infrastructure consists of three layers: a database server; communication and integration; and four functional modules including user registration and login, obtaining eco-credits, spending/donating eco-credits, and viewing eco-credit history. Multiple mobile development techniques are utilised to implement the mobile application system. A case study was conducted, demonstrating...

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...
