Abstract: To meet the requirements of product variable design by structure transplantation, part variable model and its regeneration technology were studied. With the mergence of information such as function, geometry and semantics of part and its basic structures, part variable model structure was defined. Basic part variable structure was determined by recursive subdivision of the basic part structure. Heritage, derivation or mapping approaches of the attribute information of the part variable model were proposed and regeneration of part variable model was realized. These laid foundation for product variable design. Finally，a prototype was developed and testified in the application of part variable design of oil filter base.

Key words: variable design, structure transplantation, variable model, regeneration, structure division, basic variable structure
