目的 探索设计驱动的功能创新过程，利用该过程满足用户对不同产品意义的追求，从而提升企业产品的竞争力。方法 首先，明确设计驱动功能创新的原理、特点以及实现所需的基本过程。其次，通过分析不同类型产品意义实现的方式，以及产品用户和应用场景在产品意义发掘中的作用，总结出产品意义发掘的三种模式。根据产品意义发生变化时产品功能变化的相关特点，总结出适用于设计驱动的功能创新技术。最终，形成设计驱动的功能创新过程模型。结论 设计驱动的产品功能创新过程模型可以分阶段地指导设计人员进行功能的创新设计，包括如何提出新的产品意义以及如何对产品功能系统进行调整，为产品功能的创新提供了需求拉动和技术推动之外的新思路。

This paper aims to explore the process of design-driven function innovation, and use this process to satisfy users' pursuit of different product meanings to enhance the competitiveness of products designed by enterprises.The paper first clarifies the principle, characteristics and basic process of design-driven function innovation. Then the paper summarizes three patterns to unearth product meaning by analyzing the ways of realizing different types of product meaning and the role of product users and application scenarios in unearthing product meaning. According to the characteristics of product function transformation brought about by the changes in product meaning, the paper summarizes the suitable design-driven function innovation technology. Finally, based on the above, the paper proposes a design-driven function innovation process model. The verification of an example proved that the design-driven product function innovation process model can guide designers to carry out the function innovation design in stages, including how to propose new product meaning and how to revise the product function system, which can provide new ideas different from demand-pull and technology-push for product function innovation.
