| Popis: | 92 TRIZ (is the abbreviation in Russian meaning ”the Theory of Inventive Problem Solving” ) can be defined a method of resolving problems during designing process. It holds that any invention of design could be achieved through resolving contradictions. Thus, first, it asks design engineers to search contradictions between the objects of design and suit them to the 39 engineering parameters and find the principle through referring to the contradiction matrix of TRIZ. Second, according to the suggestion, design engineers proceed to look for their own solution to achieve the objects. In other words, TRIZ can help design engineers to resolve design problem by providing an explicit direction to improve. It can reduce time for searching, avoid wasting resource and enhance the quality. However, there are two problems in using TRIZ: (1) How to determine “improve” and “aggravation”? (2) How to make “improve” and “aggravation” corresponding to any one of the 39 engineering parameters objectively and separately. Because of two problems, design engineers must determine them subjectively. So, it will expect to develop an objective and regulative method to help using TRIZ. There are two models in this thesis: (1) Contradictions extraction model: Using the correlation matrix in the house of quality of QFD to search the contradiction of twin design parameters. (2) Inductive decision model: Building an objective and individual decision model to help making “improve” and “aggravation” corresponding to any one of the 39 engineering parameters through using clustering method and decision tree. |
