傳統的產品設計方式，大都依據工程師個人的主觀判斷來進行，使得產品在未來 生產或銷售上充滿著不確定性，輕者造成產品成本的提高，嚴重者導致整個開發的失敗。 因此本研究試圖提出一個以顧客需求發展產品概念，並結合電腦輔助設計（CAD），電腦輔 助工程分析（CAE）， 以及電腦輔助製造（CAM）之樣品製作（Prototyping），所架構出來 的一套產品設計自動化系統。首先利用電腦網路即時地蒐集顧客意見，再配合品質機能展開 （QFD）將顧客的需求轉換成設計參數的工程規格，然後以參數式設計的觀念，將工程規格 自動繪出產品立體圖形，為了提高視覺效果，再將這些立體線架構圖輸出到動畫軟體進行產 品外觀模型的模擬。 本系統主要目的是希望降低研發成本，縮短研發時間，提高產品的品質以符合顧客需求，並 能在以後市場需求改變的情況下，快速地得出新的設計方案。

　　　　　The traditional product design method is implemented generally based on the engineer's personal judgement. This subjective method can create uncertainties in the production and marketing, either increases the product cost or retards the entire project. This research intends to propose a needs-based product design framework coupled with computer aided design, computer aided engineering, and computer aided manufacturing to form an automatic product design system. First of all, the customers' needs are extracted from remote terminals located at distribution centers, and transferred to the R&D division via computer network. The collected needs are next transformed into the engineering design specification using quality function development. To graphically display the product, the design specification is connected to the parametric autolisp program. Up to this stage, the market desires have been successfully converted into a three dimensional object. If vision enrichment is necessary, this object can be exported to the animation software, such as 3D Studio to render the surface texture and simulate the working conditions. This automatic product design system can reduce R&D cost, shorten product design cycle, improve product quality, and most importantly, rapidly adapt to the market change.
