目的 为解决当前市面上助眠产品对青年用户群体情感需求关注不足、缺乏针对性的问题，运用感性工学与TRIZ相关研究方法，设计一款针对青年用户群体的助眠仪。方法 首先，建立基于感性工学与TRIZ理论的助眠仪创新设计流程，收集筛选感性词汇与样本，运用感性工学构建助眠仪设计要素与感性意象的判断矩阵;其次，采用主成分分析法对数据降维，确定影响助眠仪感性判断的主要因素，分析归纳样本得到待满足设计需求特征;最后，使用冲突理论对助眠仪进行创新设计。结果 在创新设计流程的指导下，科学高效地开发设计了符合用户感性需求的助眠仪。结论 助眠仪创新设计实例表明，应用感性工学与TRIZ能科学有效地将用户情感需求转化为设计元素，并能进行符合目标用户需求的创新设计，同时，该设计流程能在相关产品进行创新设计时提供思路与方法。

The work aims to design a sleep aid for the youth user group by applying the relevant research methods of Kansei engineering and TRIZ, in order to solve the problem of insufficient attention to the emotional needs of the youth user group in the current market. Firstly, the innovative design process of sleep aid based on Kansei engineering and TRIZ theory was constructed, the perceptual vocabulary and samples were collected and screened, and the Kansei engineering was used to construct the judgment matrix of design elements and perceptual images of sleep aid. Secondly, the principal component analysis was used to reduce the dimensionality of the data, determine the main factors affecting the perceptual judgment of the sleep aid and analyze the samples to get the characteristics of the design needs to be met. Finally, the conflict theory was adopted to carry out the innovative design of the sleep aid device. Under the guidance of innovative design process, a sleep aid that met users' perceptual needs was developed scientifically and efficiently. The example of innovative design of sleep aid shows that the application of Kansei engineering and TRIZ can effectively transform users' emotional needs into design elements, and can carry out innovative design that meets the needs of target users. At the same time, the design process can provide ideas and methods for innovative design of related products.
