【摘要】：由于當前我國的產(chǎn)品創(chuàng)新設(shè)計能力低下而使得我國在全球化的市場競爭中往往處于極為不利的嚴峻形勢。同時由于產(chǎn)品的創(chuàng)新主要集中在產(chǎn)品的概念設(shè)計階段，而概念設(shè)計階段由于其復(fù)雜性及難以操作性，因而需要高層次的創(chuàng)新方法與計算機技術(shù)的支持。 而發(fā)明問題解決理論（TRIZ）則可以借助其跨學(xué)科領(lǐng)域的知識與方法工具為設(shè)計師在產(chǎn)品概念設(shè)計階段的問題創(chuàng)新求解指明方向及快速有效地解決產(chǎn)品開發(fā)設(shè)計中的關(guān)鍵問題，得到創(chuàng)造性的問題解。但由于TRIZ理論主要用于概念設(shè)計階段的問題創(chuàng)新求解，即主要解決“怎樣做”的問題，而在“做什么”，，即在問題分析、定義與轉(zhuǎn)化方面則存在一定的不足。但通過對質(zhì)量功能展開（QFD）、層次分析法（AHP）、約束理論（TOC）、功能分析（FA）等方法的有效集成與合理應(yīng)用則可以解決“做什么”這一關(guān)鍵性問題。基于此，本文提出了集多種設(shè)計方法于一體的用于問題分析、定義及求解的產(chǎn)品概念設(shè)計過程模型，并以此為基礎(chǔ)開發(fā)出了計算機輔助產(chǎn)品創(chuàng)新設(shè)計系統(tǒng)平臺sust/MTGP。本文主要的研究內(nèi)容及結(jié)論如下： （1）研究了TRIZ理論的內(nèi)涵、體系結(jié)構(gòu)、及基于知識的問題求解工具在工程創(chuàng)新設(shè)計中的問題求解過程，并確定了技術(shù)沖突與物理沖突的判定方法，為TRIZ理論與其它創(chuàng)新方法的集成及系統(tǒng)平臺的構(gòu)建，特別是問題求解模塊的構(gòu)建奠定了基礎(chǔ)。 （2）構(gòu)建了基于多方法的概念設(shè)計問題分析與定義過程模型。通過對TRIZ、QFD、KJ法、AHP、TOC、FA、頭腦風(fēng)暴法（BS法）等多個設(shè)計理論與方法的研究，提出了用戶需求參數(shù)獲取、層次化歸類及用戶戰(zhàn)略需求參數(shù)抽取方法，技術(shù)系統(tǒng)內(nèi)在組件的功能作用關(guān)系分析、功能及其屬性定義方法，導(dǎo)致系統(tǒng)出現(xiàn)不良問題的核心“根原因”分析與挖掘方法模型，“理想解”設(shè)定及求解策略判定方法模型，并在這些方法模型的基礎(chǔ)上，構(gòu)建了系統(tǒng)化的概念設(shè)計問題分析與定義過程模型。 （3）開發(fā)了基于多方法的產(chǎn)品創(chuàng)新設(shè)計系統(tǒng)平臺。從方法集成與應(yīng)用集成兩方面對TRIZ理論與QFD、AHP、KJ法、TOC等創(chuàng)新方法的有機集成進行具體的研究，并對用戶的方案管理、知識庫擴充與更新、基于問題的創(chuàng)新求解過程等進行了詳細的研究。在此基礎(chǔ)上，構(gòu)建了以TRIZ理論為核心，集多種設(shè)計理論與方法于一體的創(chuàng)新型產(chǎn)品創(chuàng)新設(shè)計系統(tǒng)框架與邏輯體系，并應(yīng)用C#2010及SQL server2008開發(fā)出了包括導(dǎo)航模塊、問題分析與定義模塊、問題求解模塊、知識與方案管理模塊等在內(nèi)的產(chǎn)品創(chuàng)新設(shè)計系統(tǒng)平臺。 （4）基于本文開發(fā)的產(chǎn)品創(chuàng)新設(shè)計系統(tǒng)完成了對杏核去殼機的創(chuàng)新設(shè)計及方案管理。并通過該創(chuàng)新實例，全面介紹了軟件系統(tǒng)的運行和操作過程，同時也測試與驗證了該創(chuàng)新設(shè)計系統(tǒng)平臺的有效性及合理性。
[Abstract]:Because of the low ability of product innovation design in our country at present, our country is often in a very disadvantageous situation in the global market competition. At the same time, the product innovation is mainly concentrated in the conceptual design stage of the product. Because of its complexity and difficulty to operate, the conceptual design stage needs the support of high level innovation method and computer technology. And the theory of problem solving is Triz). It can point out the direction of the creative solution of the problem in the stage of product concept design and solve the key problems in the product development and design quickly and effectively with the help of the knowledge and method tools of its interdisciplinary field. But because the TRIZ theory is mainly used in the conceptual design stage of the problem innovation solution, that is, mainly to solve the "how to do" problem, and in "do", that is, in the problem analysis. There are some shortcomings in definition and transformation, but through the development of the quality function, the analytic hierarchy process (AHP) and the constraint theory (TOC). The effective integration and rational application of the methods such as function analysis (FAA) can solve the critical problem of "what to do". Based on this, this paper proposes a method for problem analysis which integrates various design methods. The product conceptual design process model is defined and solved, and the computer aided product innovation design system platform sustr / MTGPis is developed on the basis of this model. The main contents and conclusions of this paper are as follows: 1) the connotation, architecture of TRIZ theory and the process of problem solving based on knowledge based problem solving tool in engineering innovation design are studied, and the method of judging the conflict between technology and physics is determined. It lays a foundation for the integration of TRIZ theory with other innovative methods and the construction of system platform, especially the problem solving module. (2) A process model of conceptual design problem analysis and definition based on multi-method is constructed. Several design theories and methods, such as brainstorming method and BS method, are studied, and the methods of user requirement parameter acquisition, hierarchical classification and user strategic requirement parameter extraction are put forward. The analysis of the function relation, the definition method of function and attribute in the component in the technical system lead to the core "root cause" analysis and mining method model of the bad problem in the system. On the basis of these method models, a systematic process model of conceptual design problem analysis and definition is constructed. The platform of product innovation design system based on multi-method is developed. The TRIZ theory and QFD-AHP KJ method are analyzed from two aspects of method integration and application integration. The organic integration of TOC and other innovative methods is studied in detail, and the user's scheme management, the expansion and updating of knowledge base, the process of problem-based innovation and so on are studied in detail. An innovative product innovation design system framework and logic system with TRIZ theory as the core and a variety of design theories and methods integrated is constructed. The paper also develops a navigation module, a problem analysis and definition module, and a problem solving module by using C#2010 and SQL server2008. Product innovation design system platform including knowledge and scheme management module etc. Based on the product innovation design system developed in this paper, the innovative design and scheme management of apricot core de-hulling machine are completed. The operation and operation process of the software system are introduced comprehensively through this innovative example. At the same time, it also tests and verifies the validity and rationality of the innovative design system platform.
