Apparatus and system for dynamically correcting posture

The patent applies the dynamics principle by replacing fixed-shape seating assemblies with a dynamic foundation member comprising multiple sections (front, central, lateral, rear) that can independently move and rotate. These sections are connected through joints allowing relative movement, enabling the seating surface to dynamically adapt to body movements while maintaining structural integrity, thus resolving the contradiction between adaptability and complexity.

The patent segments the foundation member into multiple independent sections (front section, central sections, lateral sections, rear section) that can move and rotate relative to each other. This segmentation allows each section to independently respond to body movements, providing adaptive support without requiring an overly complex monolithic structure.

The patent applies local quality by making different sections of the foundation member have different thicknesses and flexibility characteristics. The central sections have different thickness profiles than the lateral sections, allowing each region to provide specific support functions - the central sections support the pelvic area to prevent gluteal spreading while the lateral sections provide lateral stability, thus achieving pelvic stability without excessive complexity.

The foundation member is segmented into multiple sections with varying thicknesses and flexibility. The central sections are configured with specific thickness profiles to support the pelvic area and maintain the lordotic curve, while lateral sections provide different support characteristics. This segmentation allows targeted support functions without requiring a uniformly complex structure throughout.

The patent applies dynamics by making the seating surface dynamic rather than statically contoured. The foundation member sections can move and rotate to distribute pressure dynamically across the seating surface, preventing concentrated high pressure points under the ischial tuberosities while maintaining comfort through continuous adaptation to body shape.

The patent changes the parameter of surface geometry from fixed contoured shapes to dynamically variable surfaces. The foundation member sections can alter their relative positions and orientations, changing the contact surface geometry in real-time to distribute pressure evenly and prevent harmful pressure concentrations under the ischial tuberosities.
