目的 设计一款可满足用户需求的家用折叠座椅，以减少座椅在小户型的室内空间面积占用率。方法 对现有折叠座椅的设计结合TRIZ理论进行分析，通过需求层次分析法即AHP法，确定用户与产品之间的关系，得出折叠座椅功能需求指数的目标层1个、一级指数6个和二级指数15个，进而计算出各功能指数的权重值，并进行了一致性检验，确定用户亟须解决的产品设计需求问题。并运用TRIZ理论的40项发明原理解决该问题。结果 AHP层次分析法与TRIZ理论的结合，可精准分析用户的喜好，为家用折叠座椅的设计指明设计重点，从而设计出适合的座椅。

The paper aims to design a household foldable seat that can meet the needs of users, so as to reduce the occupancy rate of seats in the indoor space of small apartments. The design of the existing foldable seat was analyzed in combination with TRIZ theory, and the relationship between users and products was determined through the analytic hierarchy process (AHP) method. One target layer, six primary indices and fifteen secondary indices of the functional demand index of the folding seat were derived, and then the weight values of each functional index were calculated, and a consistency test was carried out to determine the product design requirements that users need to solve urgently. And 40 invention principles of TRIZ theory were applied to solve this problem. The combination of AHP method and TRIZ theory can accurately analyze the user's preferences and specify the design focus for the design of household foldable seats, so as to design suitable seats.
