Proceeding from the industrial design, the conceptions of product design gene are studied, the knowledge structure of product design gene is analyzed, the hybridization and variability technology of design gene is researched, and the innovation design method based on pan-ethnic group design gene is proposed. And the feasibility and effectiveness of this new method are discussed.

A design thought based on ergonomics constraint is introduced to machine tool operating components design in this paper, and a design method of machine tool operating components is researched and provided which is realized by applying database technology and Secondary development technology based a '3D entity parameterized modeling software system platform. This method tests and verifies instrumentalizing the knowledge about industrial design and ergonomics.

The keys of product development are how to distinguish the optimal designs from the bad designs at the early design stage and how to reduce the iterative error rate. Hence the evaluation method for product design schemes is important for decision making in the design process. Using the information axiom of axiomatic design, this paper combines analytic hierarchy process with fuzzy evaluation. Taking Haier U-home products as an example, this paper makes up the evaluation index of products by product s four elements, and also concludes the index information calculation formula based on information axiom. It comprehensive considerate the weight of various indexes and supply gives the calculation formulae of information content of evaluation indexes and the evaluation and decision making method for design schemes. So that it can provide a scientific decision basis and get a good foundation for the automation process ofproduct design.

From the perspective of combination principles, product form is divided into several modules for extracting profile curves; applying Genetic Algorithm (GA), product form chromosomes are coded in tree structure, through crossover and mutation operators to generate new programs; the method of product semantics is introduced into the process of evolutionary computation to enhance the interactivity of evolutionary computation by fuzzification, in which designer can decide the orientation from the selected products and guarantee the results can reflect the designer's innovative ideas. With Visual Basic and Rhinoceros platform a product form innovative design system is developed.

This paper focused on the area of simulation of man-machine applications, using JACK ergonomic software, and have a detailed analysis of sight of domain, and comfort of human-computer design factors to achieve a auxiliary design. The paper combines the emergency communications vehicles emergency communication vehicle cabin man-machine design examples to verify the effectiveness of the proposed method.
