As an innovation method to improve the degree of ideality in TRIZ,trimming has been applied in the field of product innovation and design,which can effectively solve the problem of product innovation.To better carry out the research on trimming method,the main relevant literature at home and abroad was studied and analyzed,and the concepts and main research contents related to trimming were systematically sorted out.The relevant concepts such as trimming definition and trimming process were introduced.Based on the keyword co-occurrence mapping of relat-ed literature at home and abroad,combined with the specific content of the literature,the existing research on trim-ming mainly focused on:the selection of trimming components,the search of resources for useful function allocation after determining the trimming components,the optimization of the trimming process,software implementation of the trimming method and application of the trimming method.The problems and shortcomings of the existing trim-ming method were put forward to provide reference for the future research and application of the trimming method.
