Air Spring Mattress Structure for Long-Term Comfort Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mattresses face challenges in maintaining long-term comfort and stability due to the lack of resilient behavior in homogeneous materials like polyurethane foam and latex, which eventually deform, and metal spring mattresses require a balance between stiffness and user weight, while bed frame structures are prone to damage from wear and tear, insect infestation, and warping.
Innovation Solution
The use of air springs with cavities to provide support, allowing for the addition of extrinsic materials like foam or perfume, and a bed frame structure with metal reinforcement and a polymer outer layer for enhanced durability and aesthetics, featuring a compressor system for adjustable pressure and a platform for mattress support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If homogeneous materials like polyurethane foam and latex are used for mattresses, then long term stability is provided, but resilient behavior is lost and comfort diminishes over time
Solution Approach 1:
The mattress combines polyurethane foam base with metal spring units to create a composite structure that provides both long-term stability from the foam and resilient behavior from the springs, resolving the contradiction between stability and reliability
2Reliability
If metal springs are used in mattress construction, then resilient behavior and comfort are improved, but load carrying capacity is reduced and springs fatigue under heavy loads
Solution Approach 1:
The combination of metal springs and polyurethane foam creates a composite system where the foam provides structural support for heavy loads while the springs provide resilience and comfort, overcoming the limitations of pure metal spring construction
3Ease of manufacture
If conventional bed frame structures are used, then ease of manufacture is maintained, but structural integrity is compromised due to wear and tear, insect infestation, and warping
Solution Approach 1:
The bed frame uses powder-coated metal components with modified surface properties through powder coating, providing resistance to corrosion, insect infestation, and warping while maintaining ease of manufacture through standardized metal fabrication processes
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 air spring system offers long-term comfort and stability without fatigue, while the reinforced bed frame structure maintains structural integrity and aesthetic appeal, allowing for easy assembly and disassembly, and adjustable pressure for varying support levels.
Implementation Method 1
The mattress includes an air mattress with a plurality of compressible and expandable members extending upwardly from the base. The expandable members have a cylindrical shape with a flat top that can be adjusted vertically by increasing the pressure therein.
Implementation Method 2
a bed frame structure with metal reinforcement and a polymer outer layer for enhanced durability and aesthetics

AI summary
The invention provides a mattress comprising an array of air springs, each in communication with a supply of air for selectively varying the air pressure within said spring, so as to provide a resilient body against which a user may recline; an aperture in an upper surface of each air spring, providing access to a cavity within said spring, said cavity open to ambient pressure and sealed from the air supply.
