Innovative Design Based On The Triz Theory Giant Cam

The economical competition has become the international competitive focus and important impetus. The development for new product is important for enterprise having market advantage.The "trial and error" method is well known in traditionally creative design and in scientific investigations. This process is similar to artist' s invention, and primarily decided by the inspiration and experience. While TRIZ thought creation is not inspiration, and has laws for solving problems. TRIZ is a powerful tool solving creative design in product concept design. In manufacturing, TRIZ is significant to creative design for developing product.In this paper, during the creative design of Giant Cam product, TRIZ theory is adopted in concept design, so does CAD in detailed design. Many research works are done such as TRIZ theory, the creative design in concept design of Giant Cam, the detailed design and modeling, data exchange, Engineering Database.During the creative design, firstly the product' s characteristic and evolution are to be analyzed. Then the system technology has to be forecasted to make sure if the product needs innovation. If it needs innovation, then design contradiction is analyzed. If it belongs to technical contradiction, then using TRIZ "39 standard features" to describe this contradiction and in matrix-table selecting suggested inventive principles. If the suggested inventive principles do not solve the problem, then design contradiction is analyzed again. If design contradiction belongs to physical one, then analyzing it' s type and selecting separating principles. Then according to the process of solving technical contradiction to solving physical problem. After using TRIZ tools to carry out in the creative design of Giant Cam, a series of Giant Cam are created whose working width is 1000mm and working angle has O?10? 20?30?40?50?60 degrees. It is effective to solve the problem in creative design avoiding the disadvantage using "trial and error* method.On the basis of modeling Giant Cam, the method of modeling is discussed, so does the selection of software. The concept of Template is put forward. The Template is only for customer or RD to see product' s shape or to carry out functional test. The Solidworks system is selected to model Giant Cam and other Cams.In order to keep the CAD models to be used for other people or for CAE, CAM software, it is required to select appropriate file of data exchange. For drawings, it is recommended to use DXF as file of data exchange; for models having complicated surface, using IGES; for models not having complicated surface, using STEP. Using STEP as data exchange standard, the models of Giant Cams and other Cams are converted from SolidWorks to UG? CATIA?I-DEAS.In this thesis, the managing system for product engineering database is developed in Windows 2000. In this software, it can be accomplished to browse data, append data, delete data and modify data. Moreover it has interface to SolidWorks system. In this system, product non-geometric and geometric data are to be stored and managed separately. For non-geometric data, it is stored relevantly in database. For geometric data, it is stored in computer' s physical address in files according to the type of product.Adopting TRIZ tools to carry out the creative design of Giant Cam, the concept prototype is obtained in short time. So using TRIZ tools, it can shorten periods of product innovation, increase level of product innovation, enhance the product competitive. Through the application of adopting CAD for detailed design, it can be concluded that the CAD system can increase the efficiency in detailed design, shorten design time; that selecting appropriate data exchange file can effectively transfer product data; thatmanaging system for product engineering database can increase the efficiency for managing the engineering database of product.
