Abstract

Negative attitudes toward aging make seniors have negative feelings in a variety and psychological aspects. Senior assistive reading products can help seniors read on their own, facilitate lifelong learning, and maintain the acquisition of new knowledge. Aging in learning can keep seniors linked to society. In the study of QFD (Quality Function Deployment), Web crawler was utilized to collect product evaluation data (JD.com/approx. 30 000 and Amazon/approx. 15 000) to form an evaluation vocabulary. Then, the customer requirements of senior assistive reading products were identified and converted into design requirements by combining the scenario hypothesis analysis. Next, the KJ was used to categorize customer requirements and design requirements, and 104 valid questionnaires from senior citizens over 60 years old were surveyed in order to calculate the importance of customer requirements and then the importance of customer requirements was converted into the importance of design requirements by the independent matching point method to construct the House of Quality for product. Finally, the physical contradictions, technical contradictions and object-field models of TRIZ (Theory of Inventive Problem Solving) were introduced to analyze the product in depth, and the product design contradictions were solved by the separation principle, invention principle, and standard solution system. The design strategies and practical solutions for senior assistive reading products were proposed via the QFD-TRIZ model. Integrating the QFD-TRIZ correlation model and analyzing the research around senior assistive reading products provide specific indicators for future senior assistive reading products design, expand the scope of QFD-TRIZ methodology in the research of product design for seniors, and build a logical and systematic design research model.
