Research On The Theory Of Inventive Problem Solving And Its Application For The Product Design

Design theory provides the theoretical basis for design activities and guides human designers how to accomplishing design, and plays an important role in product development. The goal of this dissertation is to study The Theory of Inventive Problem Solving and apply it on product design, and make designers get rid of the dependence of design experience and achieve the structured method for innovative product concept. The main content as following:1. The theory of inventive problem solving consists of many methods, tools and Algorithms to solve technique problem and achieve innovation development. The foundation, basic concept and method of TRIZ are analyzed, and then the problem solving flow is given based the comprehensive analysis. The advantage of TRIZ compared the traditional innovative thinking method is pointed out, which is how to achieve the best problem solution quickly.2. The concept design is the first step of product design. The concept, characteristics and development trends of concept design are analysed. Based on the analysis, a intergrated design model is given used the TRIZ tools, every application step is researched particularly, some tools are improved depend the special information. At last, a case is given to test the fessibility of model.3. The relations and difference between the axiomatic design theory and TRIZ is compared in detail, and an integration model is established based the two theories. Using the TRIZ tools to find the generic solution, design axiom to verdict the badness or goodness of the solution, the model combined both the strong points of the two theories. Case analysis showed the feasibility and could shorten the searching time markedly.4. Gone with the product become same, only depend on the faction innovation is not enough to win in the furious market competition. So, the emotional design becomes a new product design direction and method to win the competition. The basic characteristics of emotional design and customer mind of buying product are analysed, pointed out the intergartion of TRIZ and the theory of emotional design is good direction for innovation design.5. Along with the coming of information revolution, the application of MIS becomes universal, but the chaos of many concepts also is appeared and makes the company difficult to choose appropriate MIS software. Based on the direct force, Micro and Macro levels, the evolution trend of MIS is analysed used the TRIZ technology system evolution law, a direction of software is given clearly.
