Airbed Internal Support Wall for Shape Stability Under Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inflatable airbeds experience shape distortion and loss of structural stability when a user sits or lies on them, leading to discomfort due to increased internal pressure, and existing solutions either make the airbed heavy or cumbersome or increase production costs by using multiple chambers.
Innovation Solution
An internal support system comprising side support beams and an internal support wall that attaches to the top and bottom panels of the airbed, providing structural stability and preventing deformation by creating a visual impression of stacked horizontal chambers while allowing air to pass through for inflation.

Engineering Contradiction Analysis
1Stability of the object's composition
If internal structures are added to prevent shape distortion, then structural stability is improved, but weight increases making the airbed heavy and cumbersome
Solution Approach 1:
The internal support structure is divided into multiple discrete components: side support beams positioned between side panels, internal support walls extending vertically, and corner support walls. This segmentation allows the structure to provide stability through distributed support points rather than a single heavy framework, reducing overall weight while maintaining structural integrity.
Solution Approach 2:
The support structure utilizes thin-walled inflatable chambers and panels rather than rigid heavy materials. The side support beams, internal support walls, and corner support walls are constructed as flexible inflatable elements that provide structural stability through air pressure rather than dense material, significantly reducing weight while preventing shape distortion.
2Stability of the object's composition
If multiple horizontal chambers are stacked to prevent shearing forces, then structural stability is improved, but production cost increases and the airbed becomes more cumbersome to inflate
Solution Approach 1:
Multiple functions are merged into a single integrated support structure. The side support beams, internal support walls, and corner support walls work together as a unified system within one inflatable chamber, providing shear resistance and shape stability without requiring multiple separate chambers. This consolidation simplifies manufacturing and reduces costs while maintaining structural performance.
Solution Approach 2:
The internal support structure performs multiple functions simultaneously: side support beams prevent wall bowing, internal support walls maintain vertical structure, corner support walls reinforce edges, and the integrated system resists shearing forces. This multi-functionality eliminates the need for separate chambers for each support function, reducing production complexity and cost.
