Abstract

The work aims to solve the mobility problem of the disabled elderly at home and improve their quality of life. A design strategy based on SET-AHP-FBS was constructed. Firstly, the user needs were researched and analyzed through SET analysis to find the design gap of the product; Secondly, the AHP was applied to determine the need weights and the fuzzy comprehensive evaluation method was used to validate the reasonableness of the hierarchical model, and then the user needs were transformed into the product functions respectively; Finally, based on the FBS model, the mapping of the product from functions and behaviors to the structure was realized, so as to determine the product's various structural modules, and finally output of the design scheme. The design strategy based on SET-AHP-FBS had the feasibility of forming a precise and effective mapping relationship between user needs and product functions, and reducing the influence of subjective factors in the design process. It can comprehensively solve a series of problems encountered by the disabled elderly in their daily lives, such as mobility, toileting, etc. At the same time, it effectively improves the problem that the existing products often fail to accurately grasp the core needs of the users, and also provides a new design idea for the research of similar products.
