Cross-Flow Mesh Pillow Structure for Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pillows with limited breathability retain heat, leading to discomfort due to increased temperature when in contact with a person's body.
Innovation Solution
A pillow design featuring a cover layer with separate and spaced mesh portions that allow for cross-flow of air between the interior volume and the external atmosphere, enhancing airflow and reducing heat buildup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the outer layer fabric is made with limited breathability, then the structural integrity and support are maintained, but heat is retained leading to increased temperature and discomfort
Solution Approach 1:
The cover layer is segmented into multiple zones with different breathability characteristics. The body portion has lower breathability for support, while the head portion includes mesh portions with higher breathability for heat dissipation. This segmentation allows each zone to perform its specific function without compromising the overall pillow structure.
Solution Approach 2:
Different regions of the cover layer are assigned different fabric properties. The head portion features mesh portions with high breathability to manage heat and moisture, while the body portion maintains lower breathability for structural support. This local differentiation of material properties optimizes both comfort and support functions.
2Productivity
If mesh portions are added to the cover layer, then breathability and airflow are improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The mesh portions are integrated directly into the cover layer construction rather than being added as separate components. The mesh fabric is incorporated during the quilting or stitching process, merging the breathability function with the structural layers. This integration simplifies manufacturing compared to adding separate mesh inserts.
Solution Approach 2:
The cover layer incorporates porous mesh fabric in the head portion to enable airflow. The mesh structure provides inherent breathability without requiring additional active components or complex mechanisms. The porous material naturally facilitates heat and moisture management through passive air circulation.
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 maintains a comfortable temperature by facilitating airflow through the mesh portions, which are integrated into the cover layer to improve breathability and prevent undesirable heat retention.
Implementation Method 1
The interior volume is in fluid communication with the external atmosphere via the first and second mesh portions

AI summary
A pillow and a pillow cover are provided. The pillow and pillow cover include a cover layer defining an interior volume, the cover layer having a first side facing outward substantially in a first direction, a second side facing outward substantially in a second direction, opposite to the first direction, and a perimeter formed at a boundary of the first side and the second side. The cover layer includes a body portion, a first mesh portion and a second mesh portion formed separately and spaced apart from the first mesh portion. The pillow includes a filler material disposed in the interior volume. The interior volume is in fluid communication with the external atmosphere via the first and second mesh portions.
