Pocketed Column Cushions for Pressure Redistribution and Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cushions fail to effectively distribute pressure and provide adequate support and alignment for the body, often resulting in discomfort and pain due to high pressure points and inadequate cushioning.
Innovation Solution
The development of cushions featuring deformable members made of gel or elastomeric materials configured as columns within pockets formed in a support material, allowing for buckling under pressure to redistribute load and provide improved cushioning and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If conventional cushion materials are used, then the cushion structure is simple, but pressure distribution is inadequate and high pressure points occur
Solution Approach 1:
The cushion is divided into multiple independent pockets, each containing a deformable member. This segmentation allows each pocket to independently respond to localized pressure, improving overall pressure distribution while maintaining a manageable structural complexity through modular design.
Solution Approach 2:
The deformable members are designed to change their physical parameters (shape, volume, stiffness) in response to applied pressure. They transition from a rigid state to a deformable state, allowing them to adapt to varying pressure conditions and body contours, thereby improving pressure distribution.
2Reliability
If deformable members are added to improve pressure equalization, then cushioning performance improves, but device complexity increases
Solution Approach 1:
The deformable members are constructed using flexible gel or elastomeric materials that can deform under pressure. These flexible materials provide reliable cushioning performance by conforming to body shapes and redistributing pressure, while their material-based flexibility reduces the need for complex mechanical structures.
Solution Approach 2:
The cushion combines different materials (support material for structural integrity, gel or elastomeric materials for deformability) to achieve both reliable cushioning performance and controlled complexity. The composite structure allows each material to perform its specialized function.
3Stress or pressure
If deformable members are configured to buckle at threshold load, then pressure redistribution is improved, but manufacturing complexity increases
Solution Approach 1:
The deformable members are designed with dynamic buckling characteristics that activate at specific pressure thresholds. This dynamic response allows automatic pressure redistribution without complex control systems, as the buckling behavior is inherent to the member's structural design and material properties.
Solution Approach 2:
The deformable members automatically perform pressure redistribution through their buckling mechanism when threshold loads are reached. This self-service capability eliminates the need for external control systems or complex manufacturing processes, as the pressure management function is built into the member's design.
4Reliability
If gel or elastomeric materials are used for deformable members, then cushioning and shock absorption improve, but material cost increases
Solution Approach 1:
Gel or elastomeric materials are used specifically in the deformable members where shock absorption and cushioning are most needed, rather than throughout the entire cushion. This localized application of premium materials maximizes shock absorption performance while controlling overall material costs.

AI summary
Cushions include a plurality of pockets formed from a support material and a deformable member comprising a deformable polymer material disposed in each pocket of the plurality of pockets. The support material may comprise at least one of a fabric and a film. Each of the deformable members may be configured as a column having a column axis. Methods of forming cushions include forming a plurality of deformable members, forming a plurality of pockets from a support material, and disposing each of the deformable members of the plurality of deformable members in each of the pockets of the plurality of pockets. The deformable members may be configured so that each of the deformable members is isolated from the other deformable members by the support material.
