Inflatable Bed Support Structure to Reduce Side Wall Bulging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inflatable beds and mattresses with large heights often experience side wall bulging and deformation, leading to reduced stability and aesthetic issues, and existing solutions complicate manufacturing and do not fully address these problems.
Innovation Solution
An inflatable bed design featuring a top sheet, bottom sheet, side walls, first tensioning structures, and support structures, where the tensioning structures are arranged in the air chamber to limit bulging and deformation, and the support structures are positioned longitudinally along the side walls to enhance stability.

Engineering Contradiction Analysis
1Length of moving object
If the height of the inflatable bed is increased, then the comfort for users is improved, but the side walls become susceptible to bulge and deform
Solution Approach 1:
The inflatable bed is divided into multiple independent air chambers (first air chamber, second air chamber, third air chamber) separated by partition walls. This segmentation allows each chamber to independently support the structure, preventing side wall bulging while maintaining overall height and comfort.
Solution Approach 2:
Reinforcement ribs are introduced as intermediary structural elements between the air chambers and side walls. These ribs act as mediators that transfer and distribute the internal air pressure evenly, preventing localized bulging while maintaining the required bed height.
2Shape
If a middle sheet is arranged between the top sheet and bottom sheet to reduce bulging, then the side wall deformation is slightly improved, but the manufacturing process becomes more complicated
Solution Approach 1:
The reinforcement function is merged into the side wall structure itself through integrated reinforcement ribs that are formed as part of the side wall during manufacturing. This eliminates the need for separate middle sheets while maintaining side wall stability, thereby simplifying the manufacturing process.
Solution Approach 2:
The side wall structure is designed to perform multiple functions: it provides structural support, prevents bulging, and maintains air pressure distribution simultaneously through the integrated reinforcement ribs. This multi-functionality eliminates the need for additional components like middle sheets.
3Length of moving object
If the height of the inflatable bed is increased, then the comfort is improved, but the stability deteriorates and the bed is susceptible to roll over
Solution Approach 1:
The bed is divided into multiple air chambers that act as independent support units. This segmentation distributes the load and enhances overall structural stability, preventing roll-over while maintaining height for user comfort.
Solution Approach 2:
Reinforcement ribs serve as intermediary elements that connect the air chambers to the side walls and provide additional structural support. These ribs increase the moment of inertia of the side walls, enhancing resistance to rolling while allowing the bed to maintain its height.
