Ventilated Foam Pillow Structure for Heat and Sweat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pillows and mattresses with spring or foam inserts fail to effectively manage sweat and heat due to inadequate breathability, leading to sweat accumulation and discomfort.
Innovation Solution
A breathable head or body support design featuring a foam insert with open cavities and spring elements that allow for ventilation, combined with air-permeable fabric and a corrugated surface, to dissipate heat and prevent perspiration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spring insert or foam insert is used in pillows or mattresses, then support and comfort are provided, but breathability is insufficient leading to sweat accumulation
Solution Approach 1:
The patent introduces cavities with spring elements within the foam insert, creating a porous structure that enables breathability while maintaining support. The cavities allow air circulation and heat dissipation, preventing sweat accumulation while the spring elements provide the necessary support function.
Solution Approach 2:
The foam insert is segmented into multiple cavities distributed throughout its structure. Each cavity contains spring elements, creating a modular design that combines support functionality with ventilation channels, thereby resolving the contradiction between support and breathability.
2Area of stationary object
If the head or body support compresses the pillow or mattress, then contact area is established, but sweat secretions are promoted due to inadequate ventilation
Solution Approach 1:
The patent adds a three-dimensional ventilation structure within the two-dimensional contact area. The cavities extend vertically through the foam insert, creating channels that allow air flow in the vertical dimension while maintaining horizontal contact area, thus dissipating heat without reducing contact.
3Device complexity
If traditional foam inserts are used, then simplicity of structure is maintained, but internal ventilation is not achieved
Solution Approach 1:
The foam insert is divided into multiple cavities, each containing spring elements. This segmentation creates internal ventilation channels while maintaining a relatively simple overall structure that can be manufactured using standard foam molding techniques.
Solution Approach 2:
The introduction of cavities creates a porous structure within the foam insert, enabling internal ventilation and heat dissipation while preserving the fundamental simplicity of the foam-based design.
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 design provides effective ventilation and heat dissipation, reducing perspiration and ensuring comfort by maintaining a cooler surface area through automatic internal ventilation and direct heat dissipation.
Implementation Method 1
the spring elements are loaded or unloaded when the head or body moves on the pillow or mattress, whereby the respective cavity is reduced/enlarged, which in particular causes automatic ventilation of the insert
Implementation Method 2
air-permeable fabric is attached to the side areas of the block-like foam body, which fabric in particular promotes air circulation through the pillow core
Implementation Method 3
the upper side of the block-like foam body be of corrugated design

AI summary
The head bed (1) has a bedtick (2) with a block-shaped foam body (3) including a cavity (4), and a set of spring units (5) arranged in the cavity. The spring units have stiffness for preventing sealing of the cavity for automatic interior ventilation of the head bed during compressive stress. The cavity has channels extending transverse to a couch direction, where the channels are opened at side walls and at the body.
