The work aims to design a bathroom cabinet that meets the actual needs of the elderly, so as to help them better in their daily life. With Quality Function Deployment (QFD) theory and Analytic Hierarchy Process (AHP) method as theoretical support, a theoretical model of House of Quality (HOQ) was constructed for the design of bathroom cabinet suitable for the elderly, and the design practice of the bathroom cabinet was carried out based on this. Firstly, through field interviews and observation methods, the behavior status and need information of the elderly were obtained, and the KJ method was used to cluster and refine the needs to obtain the hierarchical structure of user needs. Then, the AHP method was used to calculate the weight value of each layer of needs. Next, the HOQ theory was adopted to convert the needs of users into the design features of the bathroom cabinet suitable for the elderly. Finally, according to the design features, a design scheme of bathroom cabinets suitable for the elderly that could meet the needs of the elderly best was obtained. This method can dig out the most urgent needs of users, make the designed products more scientific and reasonable, and better help the elderly to cope with the troubles caused by aging. At the same time, it also has important reference significance for the design and research of similar products.
