Inflatable Air Cushion Structure With Integrated Warming Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inflatable air cushions lack a warming function, allowing ground moisture to infiltrate, causing discomfort to users.
Innovation Solution
Incorporation of a warming layer between the upper and lower surface layers of the air cushion, with through holes aligned with bonding portions to prevent interference with the inflation process, using materials like warming cotton or aluminum foil to maintain warmth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a warming layer is added to the cushion body, then the warming function is improved, but the device complexity increases
Solution Approach 1:
The warming layer is nested within the cushion body structure, positioned between the upper and lower surface layers. This nesting approach integrates the warming function into the existing cushion structure without requiring separate external warming devices, thereby improving warmth while controlling structural complexity.
Solution Approach 2:
The warming layer is specifically positioned at the contact surface where users lie, providing localized warming where it is most needed. This targeted approach ensures the warming function is applied precisely to the area requiring it, rather than heating the entire cushion uniformly.
2Productivity
If through holes are provided in the warming layer, then the inflation process is improved, but the warming effectiveness may be reduced
Solution Approach 1:
The warming layer is designed with through holes, transforming it into a porous structure. This allows air to pass through during inflation while the surrounding warming material maintains thermal insulation. The porous design enables the warming layer to serve dual functions: facilitating rapid inflation and providing sustained warmth.
Solution Approach 2:
The warming layer is constructed as a thin film structure that can be easily penetrated by air during inflation. This thin film design allows quick inflation through the through holes while the film itself retains enough thermal properties to provide warming effect, balancing inflation speed and thermal effectiveness.
3Temperature
If the warming layer is positioned between the upper surface layer and the first connecting portion, then the warming function is improved, but the bonding connection complexity increases
Solution Approach 1:
The bonding connection is segmented into multiple bonding portions distributed between the upper and lower surface layers. This segmentation allows the warming layer to be positioned at the optimal location for warmth while the bonding portions are distributed to handle the structural connections, simplifying the overall bonding process by breaking it into manageable sections.
Solution Approach 2:
The first connecting portion of the pull strap serves as an intermediary element that bridges the warming layer and the upper surface layer. This intermediary structure facilitates the bonding connection between layers while maintaining the warming layer's position, reducing the complexity of direct bonding between the warming layer and surface layers.
