In order to improve the designer's service design management of past knowledge and user evaluation, the swarm intelligence service design system is realized by the technology of artificial intelligence and management. In this paper, CBR (Case-Based Reasoning) and Kansei engineering service design principles are used as the preliminary research framework, web crawler technology is used to collect user comments, and artificial intelligence knowledge map is used as the evaluation vocabulary database to realize the management of service design knowledge. Through TRIZ reasoning and principle arrangement, it is the main basis for design creativity output. KANO research method is used to determine the user requirements and test the output design function. The results of Kano test is ideal, and this research method has a certain reference significance. Knowledge graph has a considerable effect on knowledge management of domain service design, and the creative output can be based on certain traceable reasoning, which meets the rapid development needs of future service design.
