Nowadays, most companies are faced

Nowadays, most companies are faced with the challenge of creating products with lessenvironmental impact in order to develop a more sustainable society. Green design is one of the most important ways to cope with this challenge. A green design method is defined as a practical tool to reduce the environmental impact of a product at the early design stage. The traditional design method and processes place too much emphasis on the functional design and optimizing module design, ignoring which systems and parts have the opportunity to introduce related green concepts, such as green materials, green energy saving, and green processes at the beginning of the design, and thus missing the opportunity to be a good green product. The proposed green design method isdeveloped based on the extension method and the three Green DNAs. It has specific decomposing rules and transforming approaches, which can assist designers in solving green design problems. Clear operating principles and detailed steps are also provided for green product design in practical applications. In addition to the concept of Green DNAs, this innovative green design method provides designers with the opportunity to develop green modulars and to consider product disassembly during the process of decomposing and recomposing analysis. From the above practical case study, we canfind that this innovative method is indeed feasible and effective. We thus hope that this innovative green design method may contribute to the development and design of green products for companies. At present, this innovative method still has a major problem in that it cannot assist designers in generating detailed design solutions. In future works, we will thus aim to improve the process of idea generation by combining the extension method and TRIZ theory to develop a novel green design method. This is important, as good products must be green products in the future, when the real power of green design can be seen throughout the world.
