本論文主要研究發展一套筆記型電腦樞紐軸承之理論模式及創研流程,以達到發展樞紐軸承之創新研發為主要目標。本文利用本體論的觀念來建立樞紐軸承之知識結構,達到知識整合和知識再利用之目的。並將群組的概念套用於TRIZ 及 QFD中,對品質及技術衝突矩陣進行改善,找出相對惡化工程參數之解決方法,作為在創新研發上的一個思考邏輯。在決定樞紐軸承創研的新結構概念後,本文進而利用座標系之定義、設定及座標轉換,了解傳動機構之座標系在座標系統中的運動相對關係,推演出傳動機構之力學分析;再針對凸輪接觸面變化設計、啟動斜角原理,驗證模擬凸輪接觸面與扭力值角度。 本文以15.4吋筆記型電腦樞紐軸承實際實驗的量測扭力值報告與本文所建立的模擬扭力值相比較,以驗證本文的創新理論模式是可接受,進ㄧ步將實例及12.1吋筆記型電腦樞紐軸承新設計的接觸面積與升程高度設定,合成所需的扭力曲線;並舉實例說明凸輪磨擦面積變化設計與扭力值的關係,探討設計與製造結合之理論與分析。本研究成果將有助於了解筆記型電腦樞紐軸承理論模式及創新研發分析,為筆記型電腦樞紐軸承結構提供一個完整理論方向。
The study mainly develops a theoretical model for the hinge of notebook computer, and introduces the innovation process so as to achieve the main goal of exploring the innovative research and development (R&D) of hinge. The study uses the concept of ontology to establish the knowledge structure of hinge in order to attain the purposes of integration and reuse of knowledge. Meanwhile, the concept of clustering is employed in TRIZ and QFD to improve the quality and technology conflict matrix, and find out the solution of worsening engineering features, which serve as a thinking logic in innovative R&D. After a new structural concept for the innovation of hinge is determined, the study further uses the definition and setting of coordinate system and the coordinate transformation to understand the relative relationship between the coordinate system of driving mechanism and its movement in coordinate system. The mechanics analysis of driving mechanism is deduced. Furthermore, focusing on the changed design of the cam contact surface and the principle of starting bevel, the study proves and simulates the cam contact surface and the torsion angle. This study compares the torsion force value measured in the actual experiment of the hinge of a 15.4-inch notebook computer with the simulated torsion force value established by this study in order to prove that the innovative theoretical model is acceptable. Furthermore, the study presets the newly designed contact area and lift height for the actual case and the hinge of a 12.1-inch notebook computer. They are then synthesized as a required torsion force curve. There are examples taken to explain the relationship between the changed design of cam friction area and torsion force value. The study investigates the theories and analysis with the combination of design and manufacturing. The research results of the study shall be helpful in understanding the theoretical model for the hinge of notebook computer, and in analyzing the innovative R&D. They shall provide a complete theoretical direction for the hinge structure of notebook computer.
