The research described in this paper focuses on the development of Internet technology for web conceptual design on the basis of shared knowing and representation of design artifacts. The shared representation of design artifacts results in special type of knowledge considered as different interpretations of functional meaning and content of each artifact. Being defined as multiple Function Means patterns (FM-patterns) these interpretations are created by distributed designers for own purposes. When designing the product, individual knowledge of designers is combined to infer new knowledge. In order to illustrate the proposed approach, web-interface for creating FM-patterns and rules for functional, behavioral and design coupling design artifacts are described.
