Based on the investigation and analysis of the status for difficulties of parking in old residential areas, the paper aims to use service design methods to explore the parking service innovative design and guide practice in old residential areas. An integrated service design model is established, where desktop research and field investigation are adopted to determine the typical research object; service blueprint is used to analyze the behavior and demand of the main stakeholders; KJ method is employed to deeply analyze the parking service problem and find out service contradiction; and TRIZ approach is utilized to optimally solve the service contradiction. According to the corresponding design of specific case output, it takes the service problem of parking scheduling as the main entry point to establish the intelligent parking service system of old residential area. The system functions, including cloud management, cloud planning and cloud maintenance are proposed to optimize the parking service process. It optimizes the parking service process of old residential areas according to system perspective, and provides reference for service design-driven parking service innovation of old residential areas in China.
