Abstract:	摘要電腦鍵盤係屬國內技術成熟產業之一，近年來隨著個人電腦興起成長和沒落衰退的狀況，售價、利潤亦隨著個人電腦波動，而電腦鍵盤產於國內本屬勞力密集產業之一，在於工資、廠房、土地等多種因素考量之下，國內許多電腦鍵盤製造商則多移往中國大陸或東南亞國家進行生產製造，因此國內至2000年後電腦鍵盤產值急遽下滑。在新一代輸入法技術發展仍未見成熟之際，如何提振國內電腦鍵盤產業，使其產業能夠在創第二春，為一項重要課題。研究將鎖定筆記型電腦鍵盤，探討有關拉拔結構設計與製作相關問題，企圖瞭解筆記型電腦鍵盤機構工程，就目前研發過程所遇到新式規格需求時，結構設計和製作所產生的矛盾衝突問題。研究過程中，先經由實際訪談方式，釐清出：一、運動方式：拉拔受力方向與組裝施力方向是相反的。二、結構設計：作用力與反作用力兩者關係。三、製作模式：保有本體結構完整與尺寸準確度。等三項矛盾問題。再透過創新解題理論（Theory of Inventive Problem Solving，TRIZ），進行矛盾問題分析並提出解題概念，以確立解題方向。分析過程中將運用TRIZ理論40項原則（Principles）中：分隔（Segmentation）、萃取（Extraction）、局部特性（Local quality）、預先的反作用（Prior counteraction）等法則進行有關結構設計分析。製作模式分析則是以：事先緩衝（Cushion in advance）、等位性（Equipotentiality）、回饋（Feedback）等理論法則進行。最後將分析確立過的解題概念，透過實驗進行驗證出：一、葫蘆夾（Hook）結構應具備：事先緩衝（Cushion in advance）、等位性（Equipotentiality）、回饋（Feedback）、預先的反作用（Prior counteraction）等特性。二、結構設計部分：應注意葫蘆夾結構，頸部長短與開口大小及反變形厚度等結構設計。三、為保有葫蘆夾結構完整性，選擇非強迫脫模製作方式。且實際拉拔驗證比對數值也與規格需求相符。經由TRIZ理論，改善筆記型電腦鍵盤拉拔規格，確可滿足業界研發需求，擴大TRIZ應用於鍵盤相關領域，是否有更大效益可為後續研究探討。關鍵字：創新解題理論（TRIZ）、矛盾矩陣（Contradiction Matrix）、鍵盤拉拔結構（Pull Force Structure）。 AbstractThe manufacture of computer keyboard is one of the developed industries in Taiwan. Recent years, owing to the prosperity and recession of personal computer, the selling price and profit of computer keyboard are also fluctuated. It causes the domestic keyboard production one of the highly concentrated labor industries. Many manufacturers of computer keyboard transfer their factories to Mainland China or southeastern Asia countries due to various factors such as, employees’ salary, factory building and land so on, and that is why domestic computer keyboard industry has rapidly slumped since 2000. The development of new computer input method is still under construction, therefore how to promote domestic computer keyboard industry and create another value are an important matter.The research undertake notebook keyboard and confer the problems of pull force structure design problems. To understand what is the contradiction of structure design and the produce difficulties to engineers when they are creating a new standard, by interviewing experts to clarify：First、the motion mode: the direction of pull force and assembly is contrary. Second、structure design: the relationship between propulsion and reaction. Third、the produce mode: to keep the substance completely and the size exactly so on three contradiction problems. To analyze conflicting problems and bring up the concepts to solve the problem via TRIZ, It apply Segmentation、Extraction、Local quality、and Prior counteraction so on in the measures of forty rules of TRIZ. The produce mode analyzing is by using Cushion in advance、Equipotentiality、and Feedback and so on in theory. Finally, use experiments to test and verify the solved concept that has been analyzed. First: Hook structure should have Cushion in advance、Equipotentiality, Feedback、Prior counteraction qualities. Second: the part of structure design should pay attention to the length of neck, the dimension of mouth, and against out of shape hook structure design. Third: In order to keep hook structure integrity, engineers should choose non-force of separating tooling of production. The realistic numerical analysis of pull force proof is consistent to the required standard. Implement TRIZ to improve the pull force quality of notebook keyboard, and to cater new requirements of industry, and to be a reference for industry, government, and academy are the contributions. Keywords: Contradiction Matrix、Pull Force Structure、TRIZ。
