Latex Foam Pillow with Multi-Layer Design to Reduce Heat Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Latex foam pillows provide excellent support but often retain heat and are costly, leading users to seek alternatives that balance comfort and heat management.
Innovation Solution
A pillow design featuring a latex foam layer and an additional flexible foam component, with the latex foam layer forming one longitudinal edge and the flexible foam layer forming the other, creating a continuous outer layer that surrounds an internal foam layer, allowing for varied support surfaces and enhanced air flow through columnar voids and a breathable outer cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a latex foam pillow is used, then support and orthopedic correctness are improved, but heat retention increases
Solution Approach 1:
The pillow is divided into multiple foam layers with different properties: a latex foam layer for support and a visco-elastic foam layer for heat management. This segmentation allows each layer to perform its specialized function, resolving the contradiction between support and heat retention
Solution Approach 2:
The pillow combines two different foam materials (latex foam and visco-elastic foam) into a composite structure. The latex layer provides support while the visco-elastic layer provides pressure relief and heat management, together resolving the contradiction between support strength and temperature control
2Strength
If a latex foam pillow is used, then support is improved, but cost increases
Solution Approach 1:
The pillow applies latex foam only where maximum support is needed (one longitudinal edge and portion of second edge), while using more cost-effective visco-elastic foam for other areas. This local quality approach maintains support performance while reducing overall cost
Solution Approach 2:
The invention varies the density and thickness parameters of different foam layers to optimize performance. By adjusting these parameters, the pillow achieves adequate support with less expensive foam configurations rather than requiring expensive high-density latex throughout
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 pillow offers customizable support and comfort by varying the density and hardness of foam layers, while the air flow features reduce heat retention, providing a more comfortable and cost-effective sleeping experience.
Implementation Method 1
The latex foam layer, the internal foam layer, and the additional foam component (or flexible foam layer) are each generally comprised of a foam that is capable of suitably distributing the pressure from a user's body
Implementation Method 2
the latex foam layer defines a plurality of columnar voids that extend through the latex foam layer and are in fluid communication with the internal foam layer to allow for an increased amount of air to travel through and dissipate heat away from the internal foam layer

AI summary
A pillow is provided that includes a latex foam to provide comfort and support to the body of a user. The pillow includes a latex foam layer connected to at least one additional foam component. An internal foam layer is also included in the pillow, with the latex foam layer and the additional foam component disposed about the internal foam layer.
