The work aims to find the design method of kitchen furniture with the best combination of functions for people with lower-limb disabilities under the guidance of user behavior and demand. Firstly, initial demands of users were collected and clustered according to Kano model to determine the category and importance of each demand and screen out the key demands affecting user satisfaction. Then, the fuzzy behavior stage was used to decompose the using process of kitchen, and the user behavior scenario in each stage was obtained. Next, the general demands obtained from emotional hierarchy theory and the individual demands obtained from the scenarios of each behavior stage were considered in combination, and targeted analysis was carried out to position product design elements. Finally, design points were summarized and applied in design practice. By combining the above research methods to develop kitchen furniture design for people with lower limb dysfunction, the real demands of users can be grasped fully and the relationship between user demands and design elements is established, which effectively solves the problems encountered by people with lower-limb disabilities when using traditional kitchens, makes them participate in social life equally, and also provides certain methodological basis for similar designs.
