Solution Overview

Problem

Conventional cushioning systems lack effective distribution of compressive forces and comfort, particularly in applications like mattresses and seating, where varying load distribution and isolation are required.

Innovation Solution

The implementation of tiered void cells with a base portion and a plunger portion connected by a living hinge, allowing for telescopic collapse under compression, which enables independent movement of each tier and efficient force distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional cushioning systems use close-coupled springs or foam structures, then structural simplicity is maintained, but compressive force distribution and comfort are insufficient

Engineering Contradiction:
ImprovecomfortVSAvoidstructure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The cushioning system is divided into multiple independent pocketed spring assemblies, each containing individual springs that can move independently. This segmentation allows each spring to respond to localized pressure, improving comfort and force distribution while maintaining overall structural organization through the pocketed configuration.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If uniform cushioning structures are used throughout, then manufacturing simplicity is maintained, but varying load distribution and isolation requirements cannot be met

Engineering Contradiction:
Improveload distribution adaptabilityVSAvoidmanufacturing simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The system employs pocketed spring assemblies that can be configured with varying spring rates, densities, and arrangements in different zones. This allows local customization of cushioning characteristics to match specific load distribution requirements and isolation needs, while each pocketed unit remains a standardized manufacturable component.

Inventive Principle:
Principle #3Local quality

AI summary

The disclosed technology includes tiered void cells which provide protection, comfort, and stability during compression. The tiered void cells may be arranged in vertically stacked columns and include a stroke whereby tiers of a void cell can telescope into adjacent tiers of that void cell, as well as telescope into adjacent tiers of adjacent void cells in a column. Implementations described and claimed herein include a cushioning system comprising an array of tiered void cells, wherein each tiered void cell includes a base portion, a plunger portion, the plunger portion to collapse into the base portion under compression of the cushioning system, and a living hinge elastically connecting an inner perimeter of the base portion to an outer perimeter of the plunger portion.
