Box Spring Structure With Firm Edge and Shock-Absorbing Center
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional box springs either provide a firm foundation but fail to absorb shock or absorb shock but lack a firm perimeter support, necessitating a solution that balances both requirements for optimal mattress support.
Innovation Solution
A box spring design featuring a framed edge for rigid perimeter support combined with a raised layer of coil springs or foam extending above the edge to provide active support and shock absorption for the mattress center.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a conventional box spring is made solely of a frame, then a flat firm structure is provided, but shock absorption capability is lost
Solution Approach 1:
The box spring is segmented into distinct functional zones: a rigid frame structure for perimeter support and a separate layer of coil springs for shock absorption in the center area. This segmentation allows each component to perform its specialized function without compromising the other.
Solution Approach 2:
Different parts of the box spring have different structural properties tailored to local needs: the perimeter area has a firm frame structure to support sitting, while the center area has a softer spring layer to absorb shock and provide comfort for lying.
2Loss of energy
If a conventional box spring has a frame with an upper layer of springs, then shock absorption is provided, but firm perimeter support is lost
Solution Approach 1:
The box spring structure is divided into a permanent rigid frame that remains fixed to provide perimeter support, and a separate spring layer that can be added or removed to provide shock absorption where needed.
Solution Approach 2:
The frame structure maintains firmness at the perimeter edges where sitting support is required, while the spring layer provides localized softness and shock absorption in the center area where comfort is needed.
3Loss of energy
If the box spring provides soft support for comfort, then shock absorption improves, but structural stability deteriorates
Solution Approach 1:
The box spring is segmented into a stable rigid frame that maintains structural integrity and a separate spring component that provides shock absorption, allowing the soft element to be added without compromising the stability of the underlying structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution offers a firm perimeter support for sitting and active, shock-absorbing center support for lying, enhancing overall mattress comfort and durability.
Implementation Method 1
a layer of coil springs rests on a base and extends a predetermined distance above the framed edge to provide active support and shock absorption to a center portion of the mattress
