中文摘要:

      目的 通过青少年视力保护产品需求的系统量化，剖析当前青少年视力保护产品供给端的痛点与机会点，以循证视域下的供需耦合为目标，探索青少年视力保护产品创新设计策略，形成缓解我国青少年近视高发问题的软硬件协同设计解决方案。方法 通过半结构化访谈、文本大数据,以及用户画像、用户旅程图等服务设计分析工具挖掘用户需求。以此为基础，利用Kano模型对用户需求进行属性归类，构建需求框架，并结合层次分析法(AHP)确定需求因子权重赋值。基于质量功能展开理论(QFD)形成青少年视力保护产品QFD质量屋，论证用户需求与产品特性关系，以层层递进的循证逻辑阐释青少年视力保护产品服务系统设计的创新方法。结果 视觉采集功能(Y1)与移动端应用(R6)在质量屋的综合权重较大，是确认产品形态的关键设计依据。结论 基于Kano-AHP-QFD模型的青少年视力保护产品循证设计工作流，提出了以可串联多应用场景的“可穿戴产品”为基本形态，软件、硬件、服务互联互通，线上与线下服务相结合的青少年视力保护产品系统解决方案，为靶向缓解青少年视力保护问题提供了新思路。

英文摘要:

      The work aims to dissect the pain points and opportunities on the supply side of current products through the systematic quantification of the demand for adolescent vision protection products, so as to explore innovative design strategies for adolescent vision protection products within an evidence-based framework, and form a collaborative solution involving both hardware and software to alleviate the high prevalence of myopia among Chinese adolescents. Through service design analysis tools such as semi-structured interviews, textual Big Data analysis, user personas and user journey maps, systematic user demands were explored. Building upon this foundation, the Kano model was used to categorize user demands, construct a demand framework, and determine the weighting of demand factors by employing the Analytic Hierarchy Process (AHP). Finally, based on the Quality Function Deployment (QFD) theory, a QFD "quality house" was developed for adolescent vision protection products to demonstrate the relationship between user demands and product features. A progressive evidence-based logic was employed to elucidate innovative methods for designing service systems for adolescent vision protection products. The comprehensive weight of the visual acquisition function (Y1) and the mobile application (R6) in the quality house was significant, serving as crucial design foundations to confirm the product form. In conclusion, based on the Kano-AHP-QFD model, the evidence-based design workflow for adolescent vision protection product proposes a systematic solution—a "wearable" basic form capable of being connected across multiple application scenarios, a integration of software, hardware, and online & offline services, providing new ideas targeting the alleviation of adolescent vision protection issues.
