摘要

平面單自由度連桿組已被應用於義手機構之設計多年，但其缺點在於僅能使義手產生單一的握持動作。本文之目的為演示一個具有可切換握持動作以及鎖定握持構形功能之專利義手機構的創新設計過程。一種稱為發明問題解決理論(TRIZ)的系統化創新方法被應用於義手機構之預期功能的概念設計上。TRIZ中的矛盾矩陣及物質－場分析被有效地運用以產生這些創新概念。同時，本文使用Working Model(上標 ®) 3D軟體以進行該專利義手機構之具體化模型的運動模擬。模擬的結果顯示該專利義手機構確可產生預期的兩種不同之握持動作。

Planar linkages with one degree of freedom have been applied to prosthetic hands in the past years, but only one gripping configuration can be performed by these designs. This paper demonstrates the conceptual design processes for a patented prosthetic hand, which has the functions for switching the gripping forms and locking the gripping configuration. A systematically innovative methodology called the Theory of Inventive Problem Solving (TRIZ) is employed to generate the concepts for the desired functions. The skills of Contradiction and Substance-Field Analysis in TRIZ are effectively applied in this study. Also, motion simulation for an embodiment of the proposed prosthetic hand is given by using the Working Model(superscript ®) 3D software. The simulating results show that the design is applicable to perform two different gripping forms for hand prostheses.
