摘要

新產品開發有很大的比例注重在擴充同系列產品或改良現有產品的設計發展上，針對既有產品持續推出樣式變更(Model Change, 亦可稱產品改款)後的新產品，是常見的設計方式，故當執行樣式變更型新產品設計任務的管理時，需針對市場變化、競爭者能力、現有產品的表現等資訊加以分析管理，以輔助設計團隊運用相關資訊執行產品設計。
樣式變更型新產品的設計特色在於以既有產品為基，進行改良或擴充。針對改良所造成的系統衝突，可運用TRIZ(Theory of Inventive Problem Solving, 創新問題解決理論)協助解決。另外QDm(Quality Deployment for Market Pricing, 對應市場價格的品質展開) 是針對樣式變更型新產品開發的品質設計、價格設定、設計變更所帶來的成本企劃所發展的分析方法。整合此兩項技術，有益於樣式變更型新產品的設計。
本研究利用六標準差中的DMAIC(定義、評量、分析、改善、控制)概念來整合QDm技術以及 TRIZ理論，以發展一個『樣式變更型新產品的輔助設計流程』，並模擬一個輪椅設計例子來展示流程的應用。流程可協助設計團隊逐步得到設計所需的五項資訊，包括(1)新產品的主要設計概念、(2)新產品的品質改善目標、(3)新產品的價值評估、(4)新產品的預期製造成本資訊、以及(5)新產品的設計衝突解決建議，使用者可參考使用流程產出的這五類資訊。

Enterprises emphasize on expend a series of existing product or improving its function for new product development. Model Change is the most popular approach they used to develop a new product. In the model change process, we need to analyze the market change, competitor capability, and current product profitability in order to facilitate our design team.
The characteristic of Model Change is to improve the existed products. We can use TRIZ (Theory of Inventive Problem Solving) to resolve system conflict which occurs during the improvement process. Besides, QDm (Quality Deployment for Market Pricing) is an analysis approach which considers quality design, price, design change. It is good for Model Change to integrate these two approaches. In this research, we integrated TRIZ and QDm approaches to achieve the better new product design.
In this research, we use DMAIC (Define Measure Analyze Improve Control) concept of six-sigma to integrate TRIZ and QDm to develop a process named “Product Model Change Design Support Process”. An wheelchair model change design case study is discussed as well. This process could facilities design team obtain the following information: (1) main design concept (2)new quality elements (3)value evaluation (4) manufacturing cost (5)design conflict suggestion for product model change design.
