Advancing sustainable health: Design and optimization of high-performance inflatable structures through theoretical and experimental approaches

In response to the increasing demand for sustainable practices to address challenges in aging populations, this study advances sustainable healthcare by focusing on fall prevention strategies. A mathematical model was developed to simulate the dynamics of human body motion during falls, establishing a framework for designing effective preventive measures. Investigating the properties of nylon fabrics, we identified 20-denier (20D) fabric as optimal for air-resistance airbags due to its minimal pore size and extensive coverage area of 93.89 %, ensuring high air retention and resource efficiency. Our analysis of material characteristics, geometries, sizes, and inflation levels revealed that enhanced fabric coverage significantly improves the airbag's structural integrity and protective efficiency. Static compression tests demonstrated the airbags' capacity to safely withstand forces up to 26 N without compromising mobility, adhering to cleaner production principles by reducing waste through injury prevention. Dynamic impact tests confirmed the airbags’ ability to absorb a full 5 Joule impact within 1.2 s, effectively preventing ground contact and providing substantial cushioning. By integrating air-resistance technology into wearable safety devices, this research highlights a sustainable approach to enhancing elderly mobility, reducing healthcare burdens, and minimizing environmental impacts through preventive care.
