Solution Overview

Problem

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 Solution

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.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stress or pressure

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

Engineering Contradiction:

Improvepressure distributionVSAvoidcustomized support for different body parts

Core Design Contradiction:

Stress or pressureVSAdaptability or versatility

Solution Approach 1:

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.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

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.

Inventive Principle:

Principle #3Local quality

2Stress or pressure

If foam blocks with internal cavities are used, then firmness control and pressure distribution are improved, but structural complexity increases

Engineering Contradiction:

Improvepressure distributionVSAvoidstructural complexity

Core Design Contradiction:

Stress or pressureVSDevice complexity

Solution Approach 1:

The cushioning structure is divided into multiple foam blocks, each containing internal cavities. This segmentation allows complex cavity structures to be manufactured independently and then assembled, reducing overall manufacturing complexity while maintaining pressure distribution benefits.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Internal cavities are nested within foam blocks, creating a hierarchical structure where smaller cavities are contained within larger foam sections. This nested design provides firmness control and pressure distribution without requiring external complex structures.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Adaptability or versatility

If a multi-layered structure with wrapper is used, then tailored support and pressure modulation are improved, but manufacturing complexity increases

Engineering Contradiction:

Improvetailored support for different body partsVSAvoidmanufacturing complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The multi-layered structure consists of separate foam sections that can be manufactured independently using standard foam molding processes. Each section is then assembled into a complete cushioning structure, simplifying manufacturing compared to creating a single complex multi-layered piece.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Multiple foam sections with different properties are merged into a single cushioning structure through assembly. This combining approach allows tailored support for different body parts while using standardized manufacturing processes for each component.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

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.
