The work aims to design a new type of pineapple peeling machine in combination with the characteristics of pineapple, in order to simplify the peeling process of pineapple, improve the peeling efficiency, reduce the waste caused by peeling and meet the needs of pineapple processing. An innovative design model based on QFD and TRIZ was established. The user needs were analyzed and sorted out in QFD method and the quality house was established to determine key design elements. Then, TRIZ theory was applied to transform design elements into design technical contradictions. The problems were solved based on 40 invention principles. The solution to the technical contradiction and innovative design of the pineapple peeling machine enabled the pineapple peeling machine to be applied to different pineapples, which reduced cutting time and pulp waste and maintained the complete and beautiful shape of pineapple. The innovative design model of QFD and TRIZ can meet the user needs in the design process, shorten the innovation design time and improve the design efficiency, thus providing a new design idea for the design of pineapple peeling machine and playing an important role in the rapid development of pineapple processing industry.
