古中國簧片掛鎖是一種兼具機械和藝術的物品。雖然簧片掛鎖的機構特徵較為簡易，但其中蘊含的製造技術和文化意涵都有其獨特的價值。本研究以迷宮鎖為主題，結合榫接的工藝，開發出具有教育意義和趣味性的科學教具。首先從鎖具的發展做介紹，了解古中國簧片掛鎖的構造和類型，其中包括鎖體、鎖栓、簧片、鎖孔和鑰匙等。並對研究中使用到的榫接法，進行簡易的描述。接著針對紙、壓克力和木板三種材料，進行迷宮鎖教具的研究和開發。為了能夠不使用螺絲和膠水讓鎖具做組合，本研究應用榫接法的技巧，設計屬於各個材料的組合形式。從紙結構開始設計，參考現有產品中的卡榫設計，加以改良成適合紙鎖具結構的卡榫設計。說明設計前後的對比，知道紙鎖具的設計演變。接著介紹利用壓克力，設計另一副鎖具，描述設計中所遇到的問題以及解決方式。將原先按照紙鎖具模型簡易設計出的版本，和最終設計的版本做對照，了解壓克力鎖具是如何做設計改良的。描述使用木板設計鎖具時，將現有的榫接法和壓克力鎖具的構型做融合，並描述如何設計形狀尺寸和改良原先設計。本研究在最後針對鎖具的開鎖過程，找出鎖孔幾何設計和鑰匙的特性。利用坐標軸和鑰匙相對於鎖孔的平移與旋轉運動的定義，合成出兩面鎖孔面的各種可能的最小鎖孔方式，再從中整理出相似的鑰匙移動情況，進一步說明兩者之間的關聯性。本研究的成果，可以針對需求做不同的變化，讓古中國鎖具能更進一步的貼近大眾，增加鎖具的趣味性。

Ancient Chinese reed padlocks are both mechanical and artistic objects. Although the mechanism of the reed padlock is relatively simple, the manufacturing technology and cultural connotation of the reed padlock have their unique value. In this study, the theme of the maze lock is combined with the mortise and tenon joint technology to develop a science teaching tool with educational significance and fun. First, we will introduce the development of locks, and learn about the structure and types of reed padlocks in ancient China, including the lock body, bolt, reed, hole, and key. A brief description of the mortise and tenon joint method used in the study is also given. Then, the research and development of the maze lock was carried out for three materials: paper, acrylic, and wood. In order to make the lock assembled without screws and glue, this study applied the mortise and tenon joint technique to design the assembly form of each material. The design starts from the paper structure, and the latch design is modified to fit the paper lock structure by referring to the latch design of the existing products. It explained the contrast between before and after the design, and learn the evolution of the design of paper lock. Then, it introduced the design of another pair of locks using acrylic and describe the problems encountered in the design and how to solve them. Compare the original simple design of the paper lock with the final design to see how the acrylic lock was improved. The study describes how the existing mortise and tenon joint method is integrated with the acrylic lock configuration when designing the lock using the wooden board, and how the shape and size are designed and improved from the original design. Finally, the study identifies the geometry of the lock hole and the characteristics of the key with respect to the unlocking process of the lock. Using the definitions of translational and rotational movements of the cursor axis and the key relative to the lock hole, various possible minimum locking patterns were synthesized for the two faces of the lock hole, from which similar key movements were compiled to further illustrate the correlation between the two. The results of this study can be used to make different variations to meet the needs, so that the ancient Chinese locks can be further approached to the public and increase the interest of locks.
