Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional narrow-cell air cells in air mattresses suffer from insufficient internal pressure and are prone to air cell inversion and bending due to their design, which affects user comfort and support.
Innovation Solution
The air cell device features an air cell with upper and lower connection segments having curved portions that cross each other, partitioning the interior into three chambers, and an air transfer unit for controlled inflation and deflation, allowing for even weight distribution and preventing bending or inversion.

Engineering Contradiction Analysis
1Area of stationary object
If narrow air cells are used to maximize contact area with user's body, then the contact area is improved, but the air cells are prone to inversion and bending due to insufficient internal pressure
Solution Approach 1:
The air cell interior is divided into multiple chambers by partition walls extending from the bottom to the top surface. This segmentation provides internal structural support that prevents the narrow air cell from inverting or bending under user weight, while still maintaining the narrow profile for maximum body contact area.
Solution Approach 2:
The air cell utilizes a flexible membrane structure with integrated partition walls that maintain structural integrity through internal division. The flexible shell design allows the narrow air cell to withstand compression forces from user weight without inverting, while the thin film construction enables close conformity to the user's body surface.
2Strength
If high air cells are used to provide sufficient support, then the support capability is improved, but the overall thickness of the air mattress increases
Solution Approach 1:
Multiple internal chambers created by partition walls provide distributed support structures within a compact height. Each chamber acts as an independent support element, collectively providing sufficient load-bearing capacity without requiring increased overall air cell height, thus maintaining a thin air mattress profile.
Solution Approach 2:
Instead of increasing height (vertical dimension) for support, the invention utilizes internal partitioning that creates support structures in the horizontal plane. The partition walls extend vertically but the support mechanism is achieved through the two-dimensional arrangement of multiple chambers, providing strength without increasing the third dimension (thickness).
