Anti-collapse inflatable mattress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pull-up inflatable mattresses are prone to collapse due to connection failures between the pull strap and the mattress body, leading to a shortened service life.
Innovation Solution
An anti-collapse inflatable mattress design featuring a top sheet, side sheet, and bottom sheet with a first vertical partition layer formed by intersecting support frames in an X shape, along with additional vertical and composite partition layers, which distribute traction forces and prevent deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pull strap is connected to the mattress body at a concentrated point, then the mattress is easy to inflate and deflate, but the connection is prone to breakage causing collapse
Solution Approach 1:
The patent divides the single concentrated connection point into multiple distributed connection points arranged in an array pattern. The pull strap connects to multiple attachment points on the mattress body, distributing the mechanical stress across several locations rather than one concentrated point, thereby preventing connection breakage while maintaining ease of operation
Solution Approach 2:
The patent transitions from a single-point (0D) or line (1D) connection to a two-dimensional array distribution of connection points. This spatial distribution across the mattress surface allows the pull strap to engage multiple points simultaneously, converting a concentrated force into a distributed force system that enhances connection reliability
2Weight of moving object
If the mattress structure is simplified for easy carrying, then portability is improved, but the mattress becomes prone to collapse
Solution Approach 1:
The mattress is divided into multiple independent air chambers separated by internal partitions. Each chamber acts as an independent structural unit that maintains shape and prevents collapse. The segmentation allows the mattress to remain lightweight while gaining structural stability through the distributed chamber system
Solution Approach 2:
The patent uses flexible inflatable chambers and thin-walled air pockets to provide structural support. These flexible elements maintain the mattress shape when inflated and can be folded or compressed when deflated, enabling portability without sacrificing structural integrity during use
3Stability of the object's composition
If support structures are added to prevent collapse, then structural stability is improved, but the device complexity increases
Solution Approach 1:
The patent uses pressurized air chambers and pneumatic support structures to maintain mattress shape and prevent collapse. The inflatable chambers provide structural support through internal air pressure, eliminating the need for rigid frames or complex mechanical support systems while maintaining anti-collapse capability
Solution Approach 2:
The patent changes the physical state of the support structure from solid/rigid to gaseous/inflated. By using air-filled chambers that can be inflated to the required pressure, the mattress gains structural stability without adding permanent weight or complex mechanical components, keeping the device simple when deflated

AI summary
An anti-collapse inflatable mattress includes: an inflatable mattress body, which includes: a top sheet, a side sheet, and a bottom sheet that together define an inflatable cavity; the anti-collapse inflatable mattress further includes: a vertical partition layer disposed in the inflatable cavity and including: a first support frame and a second support frame that are disposed in a cross manner; and top portions of the first and second support frames are connected to the top sheet; bottom portions of the first and second support frames are connected to the bottom sheet; and the first support frame and the second support frame intersect in an X shape to form the vertical partition layer disposed between the top sheet and the bottom sheet. The anti-collapse inflatable mattress has a reasonable structure, strong practicality, convenient use, safety, and can prevent from collapse and extend its service life.
