The work aims to optimize the current process of DOT laser engraving, address issues such as complex control and high cost of existing tire DOT laser engraving equipment, improve the production efficiency, control the production cost, and enhance user satisfaction in terms of safety. The Kano model was employed to analyze and extract user requirements, to obtain subjective weights for each requirement element. By combining the entropy weight method, subjective factors influencing user requirements were minimized, and objective importance of the requirement elements was determined through prioritization. According to the integrated model of Kano-entropy weight method, the subjective factors of user requirements were eliminated, and a design scheme of tire DOT laser engraving intelligent equipment was produced. The final scheme was reasonable, safe and reliable, and basically met the user requirements. The product development process based on the Kano model and entropy weight method effectively improves the accuracy of extracting user requirement elements in the design process and emphasizes the coupling relationship between user requirements and product functionalities. This provides new insights for the design of tire engraving equipment.
