摘　　要：针对产品设计过程中存在的问题,将TRIZ与可拓学结合,提出一种TRIZ与可拓学交叉融合求解方法:利用可拓学简化问题、提取矛盾、拓展原理,采用TRIZ理论获得矛盾的原理解决方案、可拓模型拓展,最后应用可拓优度评价求解方案.进一步利用这种交叉融合方法求解实际问题:对于现有叉车中液压升降机构液压油泄露和效率偏低的问题,提出基于卷簧片的半自动手推叉车设计方案,对于卷簧片升降机构中存在的问题,提出倒圆加强板提高强度,并进行了升降机构的实验验证.To solve some difficult problems in the design praers,a cross integration method,based on the integration of TRIZ and the extension theory,is established,in which the problem simplification,contradiction seeking,principle extension are used by Extenics,the principle of contradiction solution,model extension are developed by TRIZ,and the scheme is evaluated by extension superiority evaluation method.Furthermore,the cross integration is used to solve the practical problems,namely the hydraulic oil leakage and low efficiency problems long existed in forklift hydraulic lifting mechanism,and the design scheme of the semi-automatic hand forklift based on tape spring shell is proposed.To counteract the problem in the tape spring lifting mechanism,the inverted circular plate is designed to improve its strength.Lastly the verification experiment on this mechanism is conducted.
