使用共用件開發是目前企業在產品開發上很常見的目標或過程，主要是在產品設計開發階段將繁瑣的生產組裝過程簡單化，縮短開發時程，降低成本提升生產效率，同時也減少客戶對新產品的適應學習時間讓產品更清楚明瞭、更容易上手使用。本研究的目的是找出產品共用元件設計的邏輯，應用質因數分解法與TRIZ法（39工程參數及40創新法則）做結合的創新手法，提出產品應用共用元件設計時可參考之流程，在應用共用元件設計時導入TRIZ創新原則，對於創作者而言也能在共用件有限的限制中產生更多的聯想與啟發，使得設計師在開發設計新產品時，能更具系統性的發展設計概念，並應用共用元件設計元素創造機能美學價值。本研究研究成果最後歸納出；五點設計規範，兩項設計矛盾，兩項設計矛盾的四點對策等開發依據並搭配應用TRIZ法產出兩件設計案並以此兩案參加設計競賽與進行模型製作；最後，並獲得了國內外共4項設計奬項，並進一步開模量產，也因此整合質因數與TRIZ於產品創作之可行性得到驗證。

The use of shared components development is a very ordinary object and process in product development. It is mainly to simplify the production process in the product design and development stage, shorten the development time, reduce the cost and improve the production efficiency. And it also reducing the experience and learning curve for customers; implement the product clearer and easier to apply and get starting. The purpose of this study is to find out the logic of the design in Shared components; applying the innovative approach by combining the factorization method with the TRIZ method (39 engineering parameters and 40 innovation rules). It importing and guiding the process of designing with the Shared components. Application of Shared components designed to import TRIZ principles of innovation, and the creator can also generating more inspiration and association in the limited conditions. In the development of new products designed, the designer could systematic developing the Concept further, and implicating the Shared components design elements to create functional aesthetic values. The research results are summarized in this paper. There are five design specifications, two design contradictions and two design contradictions. Eventually there are four countermeasures were developed and applied with TRIZ method to produce two design subjects. It also participated in the design competition and proceed to Model production. It received totally four design awards at home and abroad; not to mention the products progressing to the mass production stage at last. Integrating Decomposition and TRIZ research were verified by the feasibility of successfully product creation.
