Abstract: Based on biological engineering ideas and methods, for product innovation design, it researches and discusses on gene of case product. Defining and dividing the population of case product, it builds a model of population of case produce and describes the gene of product, to establish the hierarchy tree of decompose and the gene tree of population on case product, and expresses the gene of the population of case product. This method of product gene acquisition and expression contributes to specify, accumulate and reuse of design knowledge. Combining lock handle product as instance, it describes the acquisition and expression of product gene for details.

Key words: creative design, case product, population, product gene
