Research on Product Gene Modeling for Variant Design

The concept of product gene in variant design is proposed after a systematic study of the simiarities between variant design process and genetic engineering. Product gene modeling and gene operation supporting the variant are defined. Product gene includes the basic geometry elements representing the products' functions and constructions and the constraint relations between geometry elements. The operations of cutting, copying, replacing, variation and combination of the product gene realize the dynamic transfer of variant information and support the product variant design. Power-head in horizontal directional drilling is given as an example, which demonstrates that the approach is obviously helpful for quick of design variant product.
