Abstract

To improve the age-appropriateness and functionality of crutches for the elderly and enhance user satisfaction, an integrated model based on TRIZ and KANO model is constructed to optimize the crutches. Through the technology maturity forecasting module based on the patent analysis in TRIZ, patent search and analysis can be conducted by means of SooPat so that the life cycle and the invention direction of the product can be determined. Based on the KANO model, a Si-Di four-quadrant diagram can be obtained. The obtained user requirements can be divided into four categories, which are must- be requirements, one-dimensional requirements, attractive requirements, and indifferent requirements. Using a Likert scale, we rated all one-dimensional requirements and attractive requirements, calculated the average score of each requirement, and obtained the ranking of the requirements according to their importance. The results show that the TRIZ and KANO integrated model can optimize the existing crutches for the elderly and provide better guidance for the innovative design of crutches for the elderly.

基于TRIZ和KANO集成模型的老年人拐杖创新设计

为了提高老年人拐杖的年龄适宜性和功能性，提高用户满意度，构建了基于TRIZ和KANO模型的拐杖优化集成模型。通过TRIZ中基于专利分析的技术成熟度预测模块，借助SooPat进行专利检索和分析，从而确定产品的生命周期和发明方向。基于KANO模型，可以得到Si-Di四象限图。得到的用户需求可以分为四类，即必须的需求、一维需求、有吸引力的需求和无关紧要的需求。我们使用李克特量表对所有一维需求和吸引力需求进行评分，计算每个需求的平均分，并根据其重要性得出需求的排名。结果表明，TRIZ与KANO集成模型可以对现有老年拐杖进行优化，为老年拐杖的创新设计提供更好的指导。
