长期产品创新模型通过进化选择隐喻来描述产品的轨迹，在进化选择隐喻中，产品设计向主导设计收敛。产品创新文献倾向于基于产品物理架构的轨迹描述，而忽略了对功能架构的考虑。本文通过识别描述产品功能的基序，提供了一种新的方法来解释产品创新的生命周期。功能基序是产品多代设计中经常出现的功能块。功能图案的集合定义了产品的功能架构。使用一些关键的例子，从缝纫机的创新，本文说明了图案的出现作为检测的基础上出现的主导设计。分析了177年来与缝纫机相关的专利，以确定功能图案，这些图案表征了向主导设计的演变和趋同。结果表明，图案不改变，在很长一段时间内，一旦一个占主导地位的设计出现，即使组件继续改变。这一观察证实了主导设计作为技术框架的观点，但驳斥了设计在渐进式变革时代不再重要的观点。这些图案完善了我们对设计如何在产品创新过程中沿着特定路径演变的理解。
Models of long-term product innovation depict the trajectory of products through an evolutionary selection metaphor in which product designs converge toward a dominant design. The product innovation literature favors trajectory descriptions based on the physical architecture of products while neglecting to account for the functional architecture. This paper offers a new way to explain the life cycle of product innovation by identifying motifs that describe a product's functions. Functional motifs are recurrent function blocks across multiple generations of designs for a product. A collection of functional motifs defines the functional architecture of the product. Using some key examples from innovations in sewing machines, the paper illustrates the occurrence of motifs as the basis for detecting the emergence of a dominant design. Patents related to the sewing machine over 177 years are analyzed to identify functional motifs characterizing the evolution and convergence toward a dominant design. Results show that motifs do not change over long periods once a dominant design emerges, even though components continue to change. This observation confirms a view of dominant designs as a technological frame but refutes the notion that design no longer matters in the era of incremental change. These motifs refine our understanding of how designs evolve along a particular path over the course of product innovation.
