Abstract: Combined with the methods of network and on-the-spot user investigation, user behavior simulation analysis, and functional system analysis, this paper analyzed the problems in the usage of luggage case, utilized TRIZ innovation and invention theory to convert the problems into TRIZ standard problems. The design research was conducted by adopting the corresponding principles of invention measures, combined with the actual usage of luggage case, and the rationality of the design was verified by the Jack simulation. As a result, the existing problems of luggage case were resolved, and the innovative design solution of luggage case was obtained. Through the simulation analysis and function analysis of user behavior habits, combined with TRIZ invention principles, the luggage case design process and users’ usage model were optimized, thus improving users’ experience. 

Key words:  , luggage case, TRIZ, user behavior, functional analysis, innovative design
