Pocket Spring Mattress Structure With Air-Pumping Cushion Pockets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mattresses with pocket coil springs suffer from indentation well effects, trampoline-like cushioning, poor airflow, heat retention, and durability issues due to sheet cushioning materials, leading to discomfort, health hazards, and increased shipping costs.
Innovation Solution
A mattress design featuring pocket springs with coil and cushion pockets that allow for air circulation and independent action, eliminating the need for additional cushioning layers, thereby reducing indentation issues, improving airflow, and enhancing durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If sheet cushioning material is used above pocket coil springs, then initial loading softness and sleeper feel are improved, but indentation well effect occurs and comfort deteriorates
Solution Approach 1:
The sheet cushioning material is divided into individual pocketed portions, each enclosing a coil spring. This segmentation prevents the lateral force transmission that causes indentation wells while maintaining the cushioning benefits at each individual spring location.
Solution Approach 2:
The harmful lateral force transmission property is extracted from the cushioning system by eliminating the continuous sheet structure that connects adjacent springs, while retaining the beneficial vertical cushioning function through the pocketed construction.
2Object-affected harmful factors
If sheet cushioning material is used, then localized high pressure points are reduced, but trampoline effect increases and comfort decreases
Solution Approach 1:
The cushioning material is segmented into individual pockets that move independently with each spring, eliminating the trampoline effect caused by continuous material while maintaining pressure distribution benefits.
Solution Approach 2:
The pocketed cushioning material allows each section to move dynamically and independently with its corresponding spring, preventing the static trampoline effect of continuous material while maintaining adaptive pressure distribution.
3Ease of operation
If sheet cushioning material is used, then softer sleeper feel is achieved, but heat retention increases and health hazards occur
Solution Approach 1:
The pocketed construction creates porous spaces between individual cushion pockets that allow air circulation, reducing heat retention while maintaining the soft cushioning feel through the fabric material itself.
Solution Approach 2:
Segmenting the cushioning material into separate pockets creates ventilation channels that facilitate heat dissipation while preserving the soft tactile properties of the fabric material.
4Ease of operation
If multiple sheets of cushioning material are used, then sleeper comfort is improved, but device complexity and shipping cost increase
Solution Approach 1:
The cushioning material and coil spring support system are merged into a single integrated pocketed construction, eliminating the need for separate cushioning layers while maintaining comfort through the combined structure.
Solution Approach 2:
The pocketed cushioning material serves multiple functions simultaneously: it provides vertical cushioning, enables spring independence, facilitates airflow, and eliminates the need for additional separate cushioning layers.

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 provides improved comfort, reduced heat retention, increased durability, and cost-effective shipping by eliminating the need for additional cushioning layers, while also minimizing health hazards associated with dust and microorganisms.
Implementation Method 1
Each of the first and second cushion pockets comprises a pocket and a first resilient member disposed in the pocket of the cushion pocket
Implementation Method 2
Each cushion pocket is free standing and not connected with each other thereby creating a pumping action upon depression of the first pocket spring and/or the second pocket spring that produces circulation of air within the mattress

AI summary
The present invention is a spring unit for a mattress comprising first and second pocket springs. Each of the first and second pocket springs comprise a coil pocket comprising a pocket and a coil spring disposed in the pocket and a cushion pocket comprising a pocket and a first resilient member disposed in the pocket of the cushion pocket. Each cushion pocket is engaged with and acting only upon the corresponding coil pocket. Substantially the entire side of the pocket of the coil pocket of the first pocket spring is engaged with substantially the entire side of the pocket of the coil pocket of the second pocket spring. Each cushion pocket is free standing and not connected with each other thereby creating a pumping action upon depression of the first pocket spring and/or the second pocket spring that produces circulation of air within the mattress.
