However, due to incomplete documentation and loss of finished objects, most of the original machines cannot be verified and many of the inventions did not pass down to later generations. This book, based on the author’s re

An example regarding the conceptual design of planetary gear trains for infinitely various transmissions [1, 2] is adopted simply for the purpose of illustrating each step of the design methodology in detail.

,Su Song’s Escapement Regulator,ructure of an available design is analyzed, and the design constraints are concluded. The process of reconstruction design of Su Song’s escapement regulators is also illustrated. Finally, feasible escapement regulators of Su Song’s clock tower and modern mechanical clocks are compared.

Various atlases of generalized kinematic chains are introduced and provided as the inclusive data banks for the generation of feasible specialized chains. The concept of specialization is further presented for identifying all possible reconstruction designs. An example regarding the
