百花钟是一件精巧的钟表，制作于世纪，现藏于中国北京故宫博物院。由于它的历史价值，它通常不能被拆卸和检查，因此时钟的内部机制是未知的。本研究提供了一个系统的设计方法，以重建时钟中的五个自动机，即时间保持，音乐播放，鸭子游泳，鲜花盛开，和数字姿态。对于前两种自动机，根据对当时已知技术习俗和实践的分类和分析，推断出可行的机械结构。共提出了七个可行的机制，时间保持自动机，而三种可能的机制，音乐播放自动机。对于其余的自动机，相关机构的结构特征和设计约束，通过系统的运动分析。利用泛化和特化的概念，为鸭子游动自动机综合了7种可行机制，为开花自动机和图形姿态自动机综合了6种可行机制.所提出的方法以流程图的形式正式化。总体而言，目前的研究结果表明，所提出的方法提供了一个有用的方法来重建未知的机械设备的内部工作。
The Blossoming Flower Clock is an ingenious timepiece made in the 18th century and now preserved in Beijing Palace Museum, China. It generally cannot be disassembled and examined due to its historical value, and hence the inner mechanisms of the clock are unknown. This study provides a systematic design approach for reconstructing the five automata in the clock, namely time keeping, music playing, ducks swimming, flowers blossoming, and figures posturing. For the first two automata, practicable mechanical structures are inferred based on a classification and analysis of known technological customs and practice at the time. A total of seven feasible mechanisms are proposed for the time-keeping automaton, while three possible mechanisms are presented for the music-playing automaton. For the remaining automata, the structural characteristics and design constraints of the associated mechanisms are derived by means of a systematic motion analysis. By applying the concepts of generalization and specialization, a total of seven feasible mechanisms are synthesized for the ducks-swimming automaton, while six mechanisms are presented for the flowers-blossoming automaton and figures-posturing automaton. The proposed methodology is formalized in the form of a flow chart. Overall, the present results suggest that the proposed method provides a useful approach for reconstructing the unknown internal workings of mechanical devices.
