Prototypes have been identified as critical artifacts for generating and developing innovative products and thus stimulating economic growth. However, prototyping is also associated with a large sunk cost including the extensive time and resources required to make physical prototypes. While a wide variety of prototyping methods have been proposed to reduce the cost and time of prototype development and increase the likelihood of final product success, the majority of research to date has explored the impact of these methods using simplistic measures of the technical performance of a design. Just as it is not enough to measure the effectiveness of ideation methods only by the quantity of ideas produced, we argue that it is not enough to measure the effectiveness of prototyping frameworks through technical performance alone. Without this fundamental knowledge, we cannot understand the impact of prototyping methods on final design success or failure. Therefore, the purpose in this work is to explore the effects of a structured prototyping framework on a variety of design attributes, including user satisfaction, perceived value, technical quality, and ease of manufacturability. Specifically, the overarching research question this study seeks to answer is: what attributes of a final design are affected by the implementation of a prototyping framework? A partial factorial experimental design was used to collect data from designs produced by 77 student design teams; designs were analyzed using five robust product metrics derived from the literature. Results indicate that a structured prototyping framework can lead to improved overall design quality and that differences in the implementation of such a prototyping framework can affect the achievement of these design attributes. The findings of this work deepen our understanding of the relationship between prototyping methods and design refinement during the product development process.

X 框架的原型：探索结构化原型框架对功能原型的影响

原型已被确定为生产和开发创新产品从而刺激经济增长的关键人工制品。然而，原型制作也与大量的沉没成本相关，包括制作物理原型所需的大量时间和资源。虽然已经提出了各种各样的原型制作方法来降低原型开发的成本和时间并增加最终产品成功的可能性，但迄今为止的大多数研究都使用对原型技术性能的简单测量来探索这些方法的影响。设计。正如仅通过产生的想法数量来衡量构思方法的有效性是不够的，我们认为仅通过技术性能来衡量原型框架的有效性是不够的。没有这些基础知识，我们就无法理解原型制作方法对最终设计成功或失败的影响。因此，这项工作的目的是探索结构化原型框架对各种设计属性的影响，包括用户满意度、感知价值、技术质量和可制造性。具体而言，本研究试图回答的首要研究问题是：原型框架的实施会影响最终设计的哪些属性？部分析因实验设计用于从 77 个学生设计团队制作的设计中收集数据；使用从文献中得出的五个稳健的产品指标来分析设计。结果表明，结构化原型框架可以提高整体设计质量，并且这种原型框架的实施差异会影响这些设计属性的实现。这项工作的发现加深了我们对产品开发过程中原型方法和设计改进之间关系的理解。
