This research paper introduces a novel methodology for optimizing pressure dispersion in interactive bed systems, aiming to enhance sleep comfort while considering variegated body shapes and sleeping positions. By controlling the spring constant with precision, which is further optimized by a secondary differential filter, the proposed methodology assures ideal pressure distribution across the bed surface. At the heart of the proposed methodology lies the design of an interactive bed system that effectively responds to the unconscious postural shifts of the user during sleep. The implementation of a secondary differential filter in modulating the spring constant is an integral part of this approach, facilitating the crafting of a responsive bedding surface that promptly adapts to pressure alterations. The effectiveness of this novel method is verified through finite element method (FEM) analysis, which confirms successful pressure dispersion across the bed surface, an essential factor in enhancing sleep comfort. The research also proposes potential enhancements to this methodology, such as incorporating air-pressure control mechanisms, thereby introducing additional pressure control axes akin to those present in existing technologies. This study represents a significant stride forward in the advancement of interactive bed systems by presenting a new method for optimizing pressure dispersion, and hence, enhancing sleep comfort. The employment of FEM analysis not only validates the effectiveness of the proposed methodology but also highlights the potential for the future development of personalized and adaptive bedding solutions.
