摘　　要：为了开拓设计思路、产生创新产品方案,将设计知识有效融入产品的概念设计过程中,提出一种融合设计过程与设计知识的产品概念设计方法。定义了基于产品—功能—结构的过程模型和知识模型,利用逐层映射行为、回溯映射行为、检索行为和存储行为支持设计过程和设计知识的融合。在产品域,通过基于组合权重的双层灰色关联分析法得到待改进产品的相似产品集;在功能域,使用功能相似度算法和功能操作方法得到新产品功能架构;在结构域,利用形态学矩阵生成多种概念方案,提出基于粗数的逼近理想解排序法,并定义了综合约束指数,对方案进行定性和定量评价、得到最优方案。利用所提方法获得了一种新型美容补水仪的概念方案,从而验证了该方法的可行性。Aiming at effectively integrating design knowledge into the conceptual design process of products,aproduct concept design method by integrating design process and design knowledge was proposed,which could assist designers to explore design ideas and generate innovative product solutions.The process model and knowledge model based on product-function-structure were defined.Through level to level mapping behavior,backtracking mapping behavior,retrieving behavior and storing behavior,the integration of design process and design knowledge was realized.In the product domain,the similar product set of product to be improved was obtained by double level grey relational analysis based on combined weight.In the function domain,the function structure of new product was obtained by function similarity algorithm and function operation method.In the structure domain,the morphology matrix was used to generate new product conceptual solutions,and the technique for order preference by similarity to an ideal solution based on rough number was proposed,and composite constraint index were defined to evaluate solutions qualitatively and quantitatively.Thus the optimal solution could be acquired.The conceptual solution of new water compensator was gained to verify the validity of proposed product conceptual design method.
