The open innovation movement promotes the product design and development in the distributed knowledge resource environment, where the design entity solves the technical problems in the design and development by a large amount of services provided by the knowledge service resources outside the enterprise, and the publishing and the application of the knowledge services are mostly carried out through the Internet. The design knowledge service model based on the Internet is the key theoretical foundation of the product design based on the distributed knowledge resource environment. This paper reviews the studies of the design based on the distributed knowledge resources environment, and the product design mode in the distributed knowledge resources environment, and then analyzes the forms of the design knowledge in the distributed knowledge resources and the knowledge service classification system, finally proposes a model of the design knowledge service. Large scale applications show that the design knowledge service model proposed in this paper can well support the publication, the search, the matching and the integration of the knowledge services in the distributed knowledge resource environment.
