由于当前技术机会识别方法难以支撑不断涌现的技术创新需求,文章提出了基于专利挖掘与形态分析的技术机会识别路径,并以3D打印机为例对其进行应用分析。通过专利信息服务平台对3D打印机专利进行检索及聚类,判别打印机喷头、打印技术以及打印材料3种要素的类别,进而构建了形态矩阵,结合熵权法筛选出技术创新机会。计算分析结果显示切换式多色打印机头、激光烧结、复合材料的组合为最佳方案。
Due to the difficulty in supporting the emerging technological innovation demand due to the current technology opportunity identification methods, this paper proposes a technology opportunity identification approach based on patent mining and morphological analysis, and applies the 3D printer as an example. Through the patent information service platform, 3D printer patents are searched and clustered to identify the types of printer print head, printing technology and printing materials. Then the morphological matrix is constructed, and the opportunity of technological innovation is screened by using the entropy weight method. Calculation results show that switching multicolor printer head, laser sintering, the combination of composite materials for the best solution.
