The work aims to deeply study the service process of employee medical examination, construct the product service system of physical examination vehicles for enterprise employees, and output the corresponding scheme design to solve the problems of complex process, a large cost of time and inconvenient communication after the physical examination of enterprise employees. Firstly, through research and analysis of the current situation, needs and behaviors of the target population for physical examination, the theories and methods of product service system design were applied to summarize and condense the design strategies for the service system of the medical examination vehicles. Secondly, by combining the service blueprint, system diagram and service touchpoints in service design, the needs of stakeholders in the service system were integrated, and the product service system of the physical examination vehicles was constructed to guide the design of the hardware and information system of the physical examination vehicles. Based on the results of the preliminary study, the spatial layout and planning of the physical examination vehicles, ergonomic analysis, and the design output of the physical examination APP optimize the physical examination service process for enterprise employees to a certain extent, explore the optimization mode of physical examination, and improve the physical examination experience of users.
