Innovative Cushioning Structures for Optimal Pressure Distribution
Here’s PatSnap Eureka !
Summary
Problems
Existing cushioning structures, such as mattresses and chairs, often fail to optimally distribute pressure without peak pressure points and lack effective ventilation and customized support for different body parts.
Innovation solutions
A body cushioning pad composed of foam blocks with internal cavities to control firmness and a bi-dimensional latticed contact mat with compressible studs for pressure distribution, allowing for maximum contact surface and ventilation, while a multi-layered structure with a wrapper provides customizable support and pressure modulation.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If a single foam body with parallel channels is used, then pressure distribution is improved, but ventilation effectiveness and customized support for different body parts deteriorate
Why choose this principle:
The foam body is divided into multiple independent foam sections, each with its own channels and apertures. This segmentation allows each section to be independently designed for specific body parts (head, torso, limbs) while maintaining overall pressure distribution functionality.
Principle concept:
If a single foam body with parallel channels is used, then pressure distribution is improved, but ventilation effectiveness and customized support for different body parts deteriorate
Why choose this principle:
Different foam sections have different channel configurations, aperture sizes, and foam densities tailored to specific body parts. For example, the head section may have larger apertures for ventilation while the torso section has optimized channel patterns for pressure distribution, providing customized support throughout.

Abstract
The invention discloses a body cushioning pad, a body contact mat and a multi-layered cushioning structure composed of the body cushioning pad and the body contact mat. The cushioning pad consists of a plurality of foam blocks, each provided with an internal cavity having a predetermined size and shape to control the firmness of the block and means for maintaining the foam blocks as a unit. The body contact mat is a bi-dimensional latticed structure of spaced-apart studs made of a compressible material linked together by flexible linking elements. The multi-layered cushioning structure comprises both the cushioning pad and the body contact mat, and a wrapper to wrap the cushioning pad and the contact mat together.
