摘　　要：为了提高秸秆微粉碎效率、降低粉碎粒度,文章应用发明问题解决理论(TRIZ)指导秸秆微粉碎机的概念设计。基于功能需求分析和科学效应确定秸秆微粉碎方法;通过因果链分析、九屏幕法、理想解IFR、系统功能分析、矛盾分析、功能裁剪和资源分析等TRIZ工具对粉碎机构、分级机构和入料机构进行创新设计。基于系统化结构化的TRIZ工具辅助产品概念设计,可以提供多维度的解题方向,提高设计质量和效率。Aiming at improving the micro-grinding efficiency of straw and reduce particle size in micro-grinding, Theory of Inventive Problem Solving(TRIZ) was applied to guide the conceptual design of straw micro-grinder. The method of straw micro-grinding was determined based on functional require analysis and scientific effect. TRIZ tools such as cause-effect chains analysis, 9 screen approach, Ideal Final Result, system function analysis, contradiction analysis, function trimming and resource analysis were applied on the innovative design of crushing mechanism,grading mechanism and feeding mechanism. Based on systematic and structured TRIZ tools in the product conceptual design, multi-dimensional problem solving directions are provided, and the efficiency and quality of design are improved.
