Inflatable Bed Sidewall Frame Structure Against Rollover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inflatable beds have complex structures and are not economical, with side walls prone to bulging and rollover, failing to meet user needs for simplicity and cost-effectiveness.
Innovation Solution
The inflatable bed features a simplified structure with left and right loop-shaped frames that connect to the upper, bottom, front, and rear pieces, forming joint lines to prevent bulging and rollover, along with a tensioning assembly and air valve for inflation control, eliminating the need for additional loop-shaped frame structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If loop-shaped frame structures formed by drawstrings are provided at the side walls to tighten the gasbag, then side wall bulging is prevented, but the structure becomes complex and less economical
Solution Approach 1:
The patent integrates the loop-shaped frame structure directly into the side walls of the inflatable bed body, merging the frame function with the bed structure itself. This eliminates the need for separate drawstring assemblies while maintaining the tightening and anti-bulging function, thereby reducing structural complexity and cost.
2Ease of manufacture
If conventional inflatable bed structures are used, then manufacturing is simple, but the bed cannot effectively prevent side rollover and has fewer functions
Solution Approach 1:
The integrated loop-shaped frame structure serves multiple functions: it prevents side wall bulging, provides anti-rollover stability, and contributes to the overall structural integrity of the inflatable bed. This multi-functional design enhances versatility without significantly complicating the manufacturing process.
3Device complexity
If the inflatable bed uses a simple structure, then it is more economical, but it cannot effectively prevent side wall bulging
Solution Approach 1:
The loop-shaped frame is merged into the side wall structure itself, creating a unified design that maintains structural integrity and anti-bulging performance while avoiding the need for additional separate components. This integration achieves reliability without increasing complexity.

AI summary
An inflatable bed includes a tensioning assembly and an air valve, and further includes an upper piece, a bottom piece, a left piece, a right piece, a front piece, and a rear piece which cooperatively form an inflatable chamber. A left loop-shaped frame and a right loop-shaped frame are provided at left and right sides of the upper piece, respectively. The tensioning assembly is connected to walls of the inflatable chamber, and the air valve is in communication with the inflatable chamber. The inflatable bed has the advantages of having a simple structure and being economical under the premise of being able to prevent side rollover.
