Modular Seating Cushion Design with Reduced Foam Usage
Here’s PatSnap Eureka !
Summary
Problems
Existing seating products rely heavily on foam for support, which can be inefficient in terms of material usage and design variability, particularly in pocketed spring assemblies used in seating cushions.
Innovation solutions
A seating cushion design featuring a pocketed spring assembly with a central matrix of interconnected pockets and perimeter pockets of varying dimensions and heights, allowing for modular and customizable support structures that reduce foam usage and enhance contouring and firmness effects.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If foam is used for support in seating products, then support function is provided, but material usage efficiency is reduced and design variability is limited
Why choose this principle:
The seating product is divided into modular pocketed spring units that can be independently configured. Each pocket contains an individual spring, allowing the support structure to be segmented into discrete, replaceable modules that provide both structural support and design flexibility without requiring extensive foam usage.
Principle concept:
If foam is used for support in seating products, then support function is provided, but material usage efficiency is reduced and design variability is limited
Why choose this principle:
Different regions of the seating product utilize springs with varying characteristics (coil diameter, wire gauge, pocket dimensions) to provide localized support properties. This allows different areas to have tailored support qualities while reducing the need for uniform foam padding throughout the entire product.

Abstract
A seating cushion with a pocketed spring assembly includes a plurality of interior strings of springs joined to each other. The interior strings of springs comprises a plurality of interconnected pockets. Each pocket contains at least one coil spring. The pocketed spring assembly forms a central matrix. The pocketed spring assembly further includes at least one perimeter string of springs. Each perimeter string of springs comprises a plurality of interconnected perimeter pockets. Each pocket of the central matrix has a maximum diameter or width of a first dimension and each pocket of the perimeter string of springs has a maximum diameter or width of a second dimension. The first dimension is greater than the second dimension.
