在產品概念設計階段，設計者會將設計問題轉換成產品所能達成的功能來思考，尋找符合功能要求之可能解答，再從其中挑選具可行性者進行細部設計或改良。但此過程往往依靠設計者的靈感或經驗，是整體設計中最不易掌握的步驟。
　　為了達到輔助設計之目的，本研究以VB環境建立概念設計輔助系統，針對產品螺絲起子，應用功能分析與型態學圖表法進行其功能分解與概念合成，將符合功能之設計概念存入系統資料庫中。系統依照評估法則將使用者定義之功能權重轉換至設計概念中，成為量化的選擇標準，並判斷各概念合成的可行性，最後提供使用者合適的設計解答。此外，資料庫內的圖文資訊可連結設計軟體以實體模型展示，將有助設計者進行後續的設計變更或細部設計之工作。

　　For a design task, the designers would tackle the design problem by decomposing the task requirements into a function structure. Based on the decomposed functions, the primitive design concepts to match the desired functions may then be generated. After synthesis, analysis and evaluation of the possible solutions, the most promising and feasible design layout will be chosen for determining its details. However, the step of conceptual design is more indefinite than other steps in the whole design process and is usually influenced by the subjective views and experience of the designer.
　　To assist a designer to generate design concepts, under VB environment this study developed a computer-aided design system that employ function analysis and morphological chart method to accomplish function decomposition and concept synthesis. A database collects the design concepts that satisfy specific functions. The user then assigns weighting factor to each required function. An evaluation method uses TRIZ method together with the affiliated weighting factor to determine the priority of all possible design concepts. This priority order plays as the criterion for searching the solution among the design concepts that meet the functions. The user will then obtain a most favorite and feasible solution. Furthermore, the design information stored in the database with geometry and description can be exported as solid model between CAD systems. It will be helpful for the engineering activities to be followed such as design modification or detail design.
