Process innovation is of very great significance for a medical device enterprise to improve its ability to solve problems, lower cost and enhance patients’ comfort. In order to inspire designers to realize innovation design based on the actual conditions of the medical device enterprise, this paper has proposed a concept of process innovation design oriented Web-based process case base system model based on demand mining and conversion. The system conducts demand mining based on product enterprise competitiveness model and features of existence-presentation model, utilizes TQCSE and 5W2H1E analysis approaches to assist the medical device designers in locking demands, taking QFD iterative construction as an example, constructs a demand conversion model featuring transition from engineering features to process features, takes innovative methods as logic mainline, and utilizes browser/sever to erect process case search and exhibition models through realization technique and application flow. This paper has demonstrated case base backstage realization and management methods, showcased system interface and demonstrated its effectiveness in process design based on actual medical device cases.
