Information Supporting Technology Research Of Single Piece And Small Batch Product Innovation Design

Single-piece and small batch production enterprises design and produce products according to the needs of customers, so the design product is numerous in variety, and in a small number, it has varied specification, complex structure and relatively high technical requirements. In the production process, the orders of customers are frequently changed, and receiving orders time and the number of orders are difficult to be predicted as high-volume products. So it not only requires single-piece and small batch production enterprises can quickly give the product design when they receive the orders, but also requires they can quickly improve the designed product according to the requirements of customers after they interacted with the user. This raises a very high demand on product innovation design system.To improve the speed of the single-piece and small-batch product in innovating design, many kinds of knowledge representation ways KBE (Knowledge Based Engineering) based are used to show knowledge of the single-piece and small-patch product concerned the life cycle of the products. Various knowledge representation methods are limited and targeted. Therefore, different types of knowledge in different stages of products life cycle or in different applications should be expressed in different ways. The characteristics of knowledge should be comprehensive considered in the choice of knowledge representation in order to knowledge reasoning and knowledge maintenance.There will be many conflicts in the unit production's innovation, but it can be solved by TRIZ (Teoriya Resheniya Izobretatelskikh Zadatch) theory. According to the similarity calculation formula of similar factor, calculate the parameters one by one. The size of similar value determines that the value of similar elements is different, similar or identical. From that, 39 general engineering parameters are reorganized and grouped into 15 vector parameters, the primary TRIZ theory conflict matrixes are improved as 15 block conflict matrixes which supply the short-cut for designers to benefit the quick retrieve of contradiction analysis and the locking of range. We can introduce the TRIZ theory block conflict matrixes into the system of innovative design to set up the TRIZ theory suggestion base. In addition, the implemented process of the single-piece and small-lot products innovative design system is introduced, and fuzzy comprehensive evaluation system is proposed for the innovation.We developed an advanced and practical innovative design prototype system of single-piece and small-lot products with the model which is the combination of JAVA, Javabean and Servlet. Functional model and dynamic design of the innovative design system were analyzed, and build a Perfect database.
