古韓國欽敬閣漏為西元1438年由蔣英實根據天文觀察與計算時間所製作，主要功能為藉由水輪秤漏系統計時，及透過人偶舉牌與發聲報時。雖然有歷史文獻記載欽敬閣漏的外觀與功能，但內容並未提及內部構造，且無實物流傳，難以瞭解內部的機械組成。本研究以系統化的方法進行欽敬閣漏時辰顯示裝置的復原設計。首先，彙整當代韓國及鄰國之中國地區的科學發展、工藝技術、及其傳播與交流，探討古韓國天文和計時與報時裝置的發展，回顧欽敬閣漏的歷史記載以及近現代的復原設計。接著，在欽敬閣漏工作系統中，四層具有時辰顯示與報時功能的裝置，針對其中構造不明的部分，藉由顏氏古機械復原方法，進行可行機構的構造合成。首先以歷史文獻回顧歸納設計規格，其後利用一般化鏈圖譜，依照設計需求與限制進行特殊化，合成出所有符合當代科學理論與技術方法的可行機構。本研究產生6種欽敬閣第一層裝置的可行機構、2種的第二層機構、2種的第三層機構與2種第四層機構。而後每層挑選其一可行機構進行參數設計，並建構3D模型並進行運動模擬。最後，將每層時辰顯示裝置各取一組製作原型機，驗證運動特性及復原設計的可行性。

Heumgyeonggaknu is a water clock made by Jang Yeong-Sil in 1438 in Korea. Based on astronomical observation, the functions of this water clock include time-keeping through a water wheel and telling the hours through a set of automata puppets. However, this device was not preserved. Although the external appearance and the functions are described in ancient literature, the internal structure is unknown. In this study, the automata puppets of the Heumgyeonggaknu time-telling devices by a systematic design approach. Based on the development of science and technology in China and Korea, the historical records of Heumgyeonggaknu and the modern restoration designs, the development of ancient Korean timekeeping devices is discussed. The reconstruction designs are made through Yan’s methodology for ancient mechanisms. At first, the design specifications of the Heumgyeonggaknu time-telling devices are concluded from the review of historical documents. Then, based on the atlas of generalized chains, specialization is implemented according to design requirements and constrains. All feasible designs of Heumgyeonggaknu time-telling devices that meet the scientific theories and techniques of the subject’s time period are synthesized. As a result, six feasible mechanisms are synthesized for the automata puppets on the first floor, while two mechanisms are generated for the puppets on the second, third and fourth floors of the water clocks, respectively. Then, feasible mechanisms of each floor are selected for parameter design. And, the computer-aid virtual models and motion simulation are proposed. Finally, a set of prototypes were made for each floor of time-telling devices to verify the movement characteristics and the feasibility of the presented reconstructed designs.
