Abstract: In order to meet the individual needs of consumers, increase the efficiency and level in the stage of product design and innovation, and improve the innovation ability of design stage, this paper constructs an innovation knowledge service model based on data-driven product conceptual design. On the basis of review data and patent data, the model uses text mining and clustering analysis technology, provides the relevant knowledge service to the designers of products and the corresponding auxiliary support to the design process. Finally, an example is given to verify the validity of this model.

Key words: data-driven, product conceptual design, knowledge service

摘要： 为了满足消费者的个性化需求，提高产品概念创新设计阶段的设计效率和水平，同时提升设计阶段的创新能力，构建了数据驱动的产品概念设计创新知识服务模型。该模型基于产品的评论数据和专利数据等，运用文本挖掘和聚类分析等技术，向产品的设计者提供相应的知识服务，进而对设计过程提供相应的辅助支撑。最后，用实例验证了该模型的有效性。
