Dynamic Pelvic Seating Orthosis for Lordotic Posture Support

The patent applies the dynamics principle by replacing fixed-shape seating assemblies with a flexible membrane structure that can dynamically change its configuration in response to body movement. The membrane's inherent flexibility allows it to adapt continuously to varying body positions without requiring mechanical adjustment mechanisms, thus achieving dynamic adaptability while maintaining structural simplicity.

The patent utilizes parameter changes by varying the flexibility characteristics of different regions of the membrane. By creating zones with different flexibilities, the membrane can selectively conform to specific body contours while providing support in other areas, enabling dynamic adaptation through material property variation rather than mechanical complexity.

The patent applies local quality by transitioning from uniform thickness members to a membrane with spatially varying flexibility characteristics. Different regions of the membrane are designed with specific flexibility properties to address local anatomical requirements - providing support where needed while allowing conformity in other areas, thereby achieving effective posture correction and gluteal spreading prevention.

The patent employs composite material principles by creating a membrane structure with non-uniform flexibility distribution. This can be achieved through varying material composition, thickness, or structural characteristics across the membrane surface, combining different material properties in a single integrated structure to simultaneously achieve manufacturability and therapeutic effectiveness.
