Dynamic Orthotic Device With Rotating Pressure Points

The patent applies the dynamics principle by transforming the static orthotic device into a dynamic one. The device includes rotating disks with spherical balls that change their position and orientation during walking, causing the pressure application point to move dynamically across the foot sole. This dynamic adjustment prevents pressure overload on the same spot while maintaining structural simplicity for easy manufacture.

The patent implements periodic action through the rotating disks that cycle the spherical balls through repeated motion patterns during each walking cycle. The balls periodically change position under the foot sole, creating alternating pressure points that prevent localized overload. This periodic movement is achieved through the gear mechanisms and spring-biased arms that automatically reset and reposition the balls with each step.

The patent applies segmentation by dividing the rotating assembly into multiple independent spherical balls distributed across several rotating disks. Each ball operates independently within its own cavity, and the disks can rotate independently of each other. This segmentation allows the complex dynamic pressure distribution function to be achieved through multiple simple, identical units rather than one complex mechanism, thereby reducing overall manufacturing complexity.

The patent implements universality through the use of identical spherical balls and standardized rotating disk assemblies that can be manufactured using the same processes. The gear-toothed members and spring-biased arms are designed as universal components that work across all balls and disks. This multi-functionality approach allows a single design template to serve multiple purposes, reducing the variety of manufacturing processes needed and thereby reducing overall device complexity.
