The details in design are paid more and more attention to,some feminization design symbols are applied in the process of design,we analyze the design form with the feminization characteristics from the perspective of design shape semantics,understand the spirit of female charm,which brings the feeling of feminization design for us,and makes people feel warm,intimate and personalization.

The code of product morphologic semantics was studied,and the process of people\'s comprehension and operation to the product was analyzed from people\'s thinking habit and cognition behavior.

According to the process from collection of users requirements, conceptual design and detailed design, modeling to assembly, after the extraction and classification of the complicated domain knowledge, we put forward three layers of semantics as design semantics, modeling semantics and assembly semantics, so more domain knowledge can be used in the process of design and involved in the fi.

A Study of Computer Aided Form Design for Product Style;

The application of large-span pre-stressed truss shell system is introduced in complex form roof of Table Tennis Gymnasium for the 2008 Olympic Games——Beijing university gyms in detail,including roof form design of irregular curved surface,the characteristic of the roof structure system,loads calculation,initial tension analysis,static performance analysis,dynamic analysis and .

Based on the ergonomics alternant traits and the methods to set up contact points set or surface s form, the GA approach is brought forward for ergonomics form design the methods of genetic coding, initial colony forming, fitness function constructing and seed group selecting are discussed in detail.

Study of Electric Vehicle s Shape Design;

Considering the fuzziness of the evaluation criteria in product shape design,operational techniques of intelligent design are discussed.

Finally,a product family shape design system integration program was proposed and its software system was constructed.
