目的 促进生猪养殖业的标准化和规模化发展，提高育肥猪出栏均匀度和养殖效率，结合用户需求和动物福利理念，设计一种生猪自动称量分栏设备。方法 综合运用AHP、QFD和TRIZ等3种设计方法，首先收集用户需求并通过AHP进行需求决策分析，明确需求优先级;接着运用QFD分析用户需求与技术要求之间的关系，确定技术要求的重要性;最后应用TRIZ理论分析并解决设计矛盾，指导产品设计过程。结果 在3种方法的指导下，完成了自动称量分栏设备的创新设计。设计方案有效提升了设备的功能性和智能化水平，还显著改善了用户体验和操作效率。结论 基于该流程进行养殖设备的创新设计，可以切实关注到用户需求和动物福利，提升设备的实用性和适配性，为现代化生猪养殖业的技术进步和设备更新提供了有效的设计思路和理论支持，有望推动畜牧业的健康可持续发展。

In order to promote the standardization and large-scale development of pig breeding, improve the uniformity of fattening pig farrowing and breeding efficiency, the work aims to design an automatic pig weighing and dividing equipment by combining the user's demands and the concept of animal welfare. The three design methods of AHP, QFD and TRIZ were comprehensively applied. Firstly, user's demands were collected and analyzed by AHP for decision-making, and the priority of the demands was clarified. Then, QFD was applied to analyze the relationship between user's demands and technical requirements and determine the importance of the technical requirements. Finally, TRIZ theory was applied to analyze and solve the design contradictions and guide the design process of the product. Under the guidance of the three methods, the innovative design of the automatic weighing and dividing equipment was completed. The design solution effectively enhanced the functionality and intelligence level of the equipment, and also significantly improved the user experience and operational efficiency. The innovative design of breeding equipment based on this process can pay practical attention to user's demands and animal welfare, improve the practicality and adaptability of the equipment, provide effective design ideas and theoretical support for the technological progress and equipment update of the modern pig breeding industry, and is expected to promote the healthy and sustainable development of the animal husbandry industry.
