系統化之產品設計過程其步驟包含有設計問題之瞭解，就需求條件轉換成設計規格，再由要求之功能推衍出設計之構想，接著依構想之功能轉換成具體之幾何形狀，經評估後挑選可行性較高的雛型設計作必要之分析及模擬，直至完成各零組件之細部設計。
其中由抽象之設計功能推導出具體之結構及機構，多憑設計者之創意能力。但設計者之創意能力常變化難測，因此該過程是最不易掌握之步驟。TRIZ是一種系統化的創意設計方法，依其39個參數、40個創新法則、76種標準解答、物質-場分析等分為不同的部份，本研究嘗試結合QFD、創造性機構設計及TRIZ方法，引申統合為”系統化TRIZ方法”，以有系統之步驟推導出可能之雛形構想，作為後續之結構分析、機構拓樸設計及機構模擬之依據。並以一個應用案例，驗證各相關設計方法之聯貫性，作為提昇設計自動化之參考。

The process of systematic design includes understanding design task, creating design concepts, generating primitive design layouts, evaluating each layout and selecting an appropriate layout to complete the details of each component and assembly. Among the design process, generating design concepts and primitive layouts depend on the creativity of the designer. However, a designer would hardly create new design concepts if no systematic innovative process can be followed.
The research will try to employ the TRIZ method, an inventive method, step by step to generate new design concepts for a design problem. To extend the TRIZ method, the “Integrated TRIZ method” will link to other design methods, such as QFD, Problem Formulation, as the problem definition generator. Then the sorted problem can be imported into the process of the Integrated TRIZ Method to create new designs. In this research working special effort would be needed to develop possible results by creative mechanism design when the Integrated TRIZ Method is applied to the field of mechanical design.
A case study of a rock-climbing tool, chock, has been used to demonstrate the process of Integrated TRIZ Method. Several conceptual designs can be generated step by step and the corresponding geometric models are constructed by using a CAD software (i.e. I-DEAS). The study has shown the capability of a systematic innovative design method for creating design concepts. Furthermore, the creative design process can be envisaged as the basis for design automation in the future.
