Sustainable design is an important design strategy for people to establish a healthily developmental circular economy. With the development, product design fields have changed accordingly, many successful product designs were created for sustainable effects with innovative design methods, including the designs of end-of-life treatment, product life cycle, and product-service system (PSS). There were some design solutions in design cases ranging from product itself or offered services, and these sustainable product designs utilized existing or new skills and technologies, utilizing resources and materials which were manufacturable and maintained to benefit locally, to achieve benefits on the various aspects of sustainability e.g., social, environmental, and economic. Analyzing and evaluating these design methods applied in typical design cases, assisted to summarize effective design approaches and strategies in sustainable product design. Some values behind the design were thus recognized based on the evaluated criteria which were used to judge product quality. The findings indicated the relevant design interventions in response to the design solutions could influence to reach sustainability, thereby assisting designers and researchers to learn closely.
