Research And Realization On The Object-Oriented Variant Design Method Of Configuration Products

Under the production mode of Mass Customization, new demands of product design have been required due to customers'individual needs and rapid changes in the market. How to respond to customer needs and market changes are the main tasks which are concerned and studied in every enterprise. As regards, this thesis promotes a variant design method based on product configuration. Under the support of parametric design method, product configuration design technique, and object-oriented product design technology, the principles, processes and methods of product configuration design technique supporting the variant design are expounded, product family table as an intermedium. The principles and methods of product structure variant design and product variant design in detail are researched based on the product configuration, and also the principles and methods of web-based product variant design are studied. At last, a prototype system of product variant design is developed, considering the needs of enterprises.First, with the combination of product variant design requirements, a number of key technologies of object-oriented configuration product variant design method are researched and analyzed, including product parametric design technology, product configuration design technique and object-oriented product design method, which establishes the foundations of theoretical research and practical application for product configuration design and product variant design.Furthermore, the framework of product configuration design is promoted, the rules of product configuration design are expounded based on the product family table, the interfaces between product configuration members are analyzed, and the basic flow of product configuration design is given.Moreover, based on the product configuration design, the product structure variant design, variant design in detail and web-based variant design technique are all researched. The product structure variant design is achieved through modular hierarchical structure and module coding technology. The passing and driving of parameters in product variant design in detail are realized with the hierarchical association of tabular layouts of article characteristics and product configuration parameters based on the parametric design technology. The structure, basic principles and methods of web-based product variant design are expounded, and the three-dimensional visualization of client-side models is enabled through the eDrawings browser.Finally, with the combination of application needs, a variant design prototype system is developed on the SolidWorks platform, and an application example of gear product is given to illustrate the working process and verify the feasibility of the research work.
