In view of the design scheme convergence in the process of product design, a method of product extension case rea-soning based on region semantic correlation is presented. In combination with product semantics and primitives theo-ry in extenics, the knowledge representation method in process of product design and convergence process of design cases were studied. In the convergence process, the semantic correlation function should be established first, and the evaluation method for convergence process of product family is presented. According to the semantic relevant web and partial correlation degree evaluation, the product extension case reasoning for product design can be achieved. This paper take a machine tool concept design as an example, and this method has a good effect in the design proses which can be a method reference for case reasoning in product design.
