Developing health-related products to enhance quality of life for senior adults and working women

With the elderly population increasing, there is a growing need for products that can aid their daily activities, such as grocery shopping. To address this issue, this study applies the product design and development method to create a grocery shopping cart that can improve the shopping experience for senior adults. Through a survey, customer feedback was collected to identify the problems and requirements of senior adults during grocery shopping. The results were then used to create a new design by combining the existing product with functional components like a smartphone holder, fan/cooler, lift-up plate, sensor, and light. Several methods, including Quality Function Deployment and Bartlett's Test, were employed to ensure the usefulness and quality of the new design. Simulated force and material analyses showed that HDPE and stainless steel were suitable for the container part (basket) and foot supporter, respectively. The outcome of this study can be used as a guideline for mass production of the designed grocery shopping cart for senior adults, which can enhance their quality of life by providing a more comfortable and convenient shopping experience. Further revisions and improvements may be made based on feedback from users. Proper accomplishment of design under constraints can be facilitated with the assistance of product design and development (PDD). The development of a durable, flexible, and accessible briefcase-style bag for work-and-travel activities is presented in this study. The target customers are set as women who require specific details that lead to the comprehension of hidden issues by the designers. Key considerations for the bag's design include providing ample space and a strong body to store many items while preserving them in good condition. A solid-based baggage cover was applied to provide a shock-absorption structure. The bag’s size must not exceed 40cm x 20cm x 25cm. The weight of the bag and its contents was set at 4 kg, which is the main parameter for Finite Element Analysis (FEA). To ensure safety, force distribution around the bag was simulated. When a 1000 N external force or impact force was applied to the front/back area of the bag for a relatively short period, the developed bag remained usable without any cracks found. The main body of the bag is made of polycarbonate (PC) - Acrylonitrile Butadiene Styrene or ABS plastic material, which is durable and strong. The analyzed results can serve as key guidelines for manufacturers or customers to assist work-and-travel activities with happiness. Designing a bag under constraints requires careful consideration of various design elements and materials. With the utilization of product design and development (PDD), a bag that satisfies the unique needs of the target customers can be developed, providing a durable and flexible solution for work-and-travel activities.
