Abstract Symmetry breaking phenomena exist in many mechanical products. Based on an analysis of the variation in physical features in several design examples, mechanical symmetry breaking concept systems that consist of general requirements, working principles, and cross-scale mechanical structures are established from the macro to micro levels and in both machine assembly and the design of parts. The connection between symmetry breaking and product requirements is systematically studied. Eight design principles using symmetry breaking to achieve mechanical functions, performance, and constraints are proposed. The method and process of applying symmetry breaking in mechanical concept design are described. These principles, method, and process are then used in the concept design of a gear chain. With symmetry breaking characters, the transmission stability of the newly innovated gear chain is greatly improved, compared with traditional ones.
