Abstract: The principle and strategy on systematic design of mechanical products are presented. It is suggested that the surroundings, lateral relation, and the experiencing track of the design object should be taken into account for systematic design. To improve the competency of mechanical products, not only the main system but also its subsystems should be optimized. It is necessary to establish the complex model conceming subsystem properties and their influence on main system before the optimal design of mechanical system. For optimization of certain subsystem, the property factors of the sub-structure, which greatly influence the whole system’s performance, should be selected to constitute the multi-object function. When certain property of the whole system is to be enhanced, the sub-structures, which greatly influence the specific property of the whole system, should be ameliorated.
