The work aims to provide users with a more comfortable and reasonable toilet assisted rising scheme to solve the problem of inconvenient rising encountered by the elderly with decreased physical function in using the toilet. Based on the principle of barrier-free design, the characteristics of user behavior were analyzed, and the user demand-centered toilet design was put forward. Kansei Engineering was regarded as a method to obtain user demands and technical demands. The user demands were divided into the first level and the second level, and the AHP was used to build the demand hierarchy analysis model. Then, the quality requirements of the toilet products were classified and sorted out. The house of quality was constructed and the body of the house was the correlation analysis of user demands and product quality requirements, and the roof part was the negative correlation analysis of product technical demands. The targeted design of contradictory technical points were found out and combined with the TRIZ theoretical conclusions, the solutions were proposed. The innovative design of the existing toilet can improve the safety, effectiveness, ease of use and comfort of the toilet and provide reference for the innovation of sanitary ceramic products.
