摘　　要：为了提高产品生态设计效率和创新效率,针对产品生态设计的特点,提出一种基于发明问题解决理论(TRIZ)融合规则推理(RBR)和案例推理(CBR)的产品生态设计方法.该方法采用本体表示产品案例和设计知识,根据规则和案例推理选择案例作为原始方案,结合推理结论和新产品设计目标对原始方案进行修改,形成初步设计方案;选择可改善的生态效率要素,利用TRIZ工程参数与生态效率要素关联表构建矛盾矩阵,运用矛盾矩阵和技术系统进化理论等TRIZ工具进行求解.研究了案例检索的算法,构建基于TRIZ融合规则和案例推理的产品生态设计平台,并通过三相鼠笼式异步电动机的设计案例验证该方法的有效性,缩短了设计周期并改进了产品的生态性.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 apreliminary 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 TRIZbased product eco-design system integrating RBR and CBR was established.Finally,a design case of threephase squirrel cage induction motor was introduced to validate the effectiveness of this approach.The design cycle was shortened and meanwhile the ecology was improved.
