In order to solve the problems of low efficiency and slow delivery of the integrated packaging design for engine parts, a design method based on the concept of constraint satisfaction was introduced. By adopting order quantity, container size, parts size and placement method, packaging material specifications and other boundary conditions as constraints, the package scheme of engine parts was designed, based on which, the stack performance check and optimization process was formed. This design method improved the design efficiency of packaging engineers and could be used as the basic logic of engine assembly packaging agile design system.
