Abstract: With the development of network technology, collaboration on the Internet becomes widespread. With the method of knowledge collision model, the ability of communication and collaboration among the operators distributed on different locations can be improved. In this paper the concept of "knowledge collision" is interpreted, and its structure and method are analyzed. And then a system named KCBVWS（knowledge collision based virtual workshop system） is presented, which combines the methods of KM （knowledge manage） and the metasynthesis. The following expatiates on the components, architecture, and feature of KCBVWS. The application and prospect of KCBVWS are also discussed at the end of the paper.
