目的 针对目前视障人群自行服用液体药品非常困难的问题，设计出一种视障者液体药瓶。方法 运用QFD理论，对目标用户进行调研，得到符合信度要求的用户需求权重，通过专家小组将用户需求转化为技术特征，构建出视障者液体药瓶质量屋，得出技术特征排序以及它们之间的相关性，然后利用TRIZ理论将呈负相关的技术特征进行转化，选择相应的发明原理进行技术冲突的解决。结果 综合考虑技术冲突的解决以及重要的技术特征，设计出视障者液体药瓶。结论 通过QFD与TRIZ理论集成可以设计出使用效果良好的视障者液体药瓶，使得视障者能够独立使用本药瓶进行液体药物服用，解决了视障者服用液体药品困难的问题，增强了视障者生活自理能力，验证了QFD与TRIZ集成设计方法在产品创新设计中的有效性。

Aiming at the problem that it is very difficult for the visually impaired to take liquid medicine by themselves, the paper intends to design a kind of liquid medicine bottle for the visually impaired. The QFD theory is used to investigate the target users and get the weight of the user needs that meet the reliability requirements. The expert group transforms the user needs into technical characteristics and constructs the quality house of liquid medicine bottles for the visually impaired to obtain the technical characteristics ranking and the correlation. Then the TRIZ theory is used to transform the negative technical characteristics, choose the corresponding invention principle to solve the technical conflict. Considering the solution of technical conflict and the important technical characteristics, the liquid medicine bottle for the visually impaired is designed. Through the integration of QFD and TRIZ theory, a good liquid medicine bottle for the visually impaired can be designed for the visually impaired to take liquid medicine, enhance the self-care ability, and verify the effectiveness of QFD and TRIZ integrated design method in product innovation design.
