Abstract
The original crossbow was one of the most important weapons in ancient China. Since crossbows have diversified types and were widely used in ancient China after the Spring and Autumn Period (770-476 BC), the original crossbow should have many designs in different eras and regions. The aim of this work is to synthesize mechanism structures of the original crossbow. Based on the analyses of crossbows, the structural characteristics and design constraints of this device are concluded. Then, according to the concepts of generalization and specialization subject to the concluded design constraints, twelve feasible structures of mechanism that meet the technological standards of the subject’s time period are reconstructed.
