A kano model-based design for age-friendly shopping carts in large commercial malls

With the growing aging population, improving the shopping experience and safety of elderly users in malls is increasingly important. This study applies the Kano model to design an age-friendly shopping cart based on the needs of 100 older adults. Their demands were categorized into functional, safety, and experiential aspects. The Better–Worse coefficient analysis prioritized key features to guide product development. The findings offer practical strategies to enhance elderly users’ autonomy and satisfaction in shopping environments.
