The work aims to integrate the concepts and principles of inclusive design into the service design based on the design direction of the aging social background and optimize the service design process from the perspective of inclusiveness, to improve the inclusiveness of service design and build an elderly-oriented medical service system with better experience. Through literature analysis, the research status of elderly-oriented service design, the inclusive design concept and its advantages to solve the aging problem were obtained. Through user research methods such as in-depth interviews and field surveys, a typical user journey map of elderly patients with chronic diseases was constructed and service pain points were sorted out and classified. Design opportunities were found out from the service contact points and the entire service process. The service contact points were optimized and designed systematically according to the summarized inclusive principle. The built medical service system was expressed through tools such as service blueprints. The service pain points improvement principles, elderly-oriented service pain points classification and elderly-oriented service design process based on inclusiveness and the inclusive evaluation method for service processes were proposed. The integration of inclusive design concepts can increase the inclusiveness of service design and improve the service experience of the elderly. The inclusive elderly-oriented service design provides an entry point for the service design research of the aging population and reference value for the design of elderly-oriented medical service processes.
