To improve the efficiency of product eco-design and innovation, a theory of inventive problem solving (TRIZ) -based product eco-design approach integrating rule-based reasoning (RBR) and case-based reasoning (CBR) was put forward with respect to the characteristics of product eco-design. Product cases and design knowledge were represented through ontologies. An original design solution was selected from extant cases based on RBR and CBR and it was modified according to the results of reasoning and the design goal for new product, forming a preliminary design solution. Then improvable factors on eco-efficiency were selected, and a paradox matrix was constructed using TRIZ engineering parameters-eco-efficiency parameters correlating table. As a result, the improvements were solved through the paradox matrix and the technique system evolution theory. Furthermore, the case retrieval algorithm was studied and a TRIZ-based product eco-design system integrating RBR and CBR was established. Finally, a design case of three-phase squirrel cage induction motor was introduced to validate the effectiveness of this approach. The design cycle was shortened and meanwhile the ecology was improved.
