In view of the lack of systematic innovative design theories and methods in the field of light industry equipment, the paper aims to use TRIZ theory to guide the innovative design in the field of light industry equipment. The research status of TRIZ theory, in-depth knowledge acquisition based on TRIZ, development of computer-aided innovation system based on TRIZ and application of TRIZ in light industry in China were sorted out and analyzed. The research deficiency of TRIZ in light industry equipment field is summarized, and the research prospect of innovative design in light industry equipment field is put forward. The focus of future research on innovative design in light industry equipment field is pointed out, and the research framework of innovative design is constructed to provide methods and ideas for carrying out innovative design of light industry equipment.
