Air bed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air beds are unstable and prone to deformation due to insufficient supporting capability, which complicates processing and increases costs, while dividing them into multiple air chambers enhances stability but raises production difficulties and costs.
Innovation Solution
An air bed design featuring an upper sheet, lower sheet, left and right side sheets, first and second structural pull belts, where the sheets form a single air chamber with the pull belts ensuring stability and supporting performance, simplifying the manufacturing process and reducing material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the air bed is divided into multiple air chambers to improve supporting capability, then stability is improved, but processing difficulty increases and production efficiency decreases
Solution Approach 1:
The patent divides the air bed into multiple independent air chambers that are connected through a common bottom sheet. Each air chamber can be independently inflated and deflated, providing stable supporting capability while allowing simple processing through modular construction. The bottom sheet serves as a shared component that connects all chambers without requiring complex assembly.
2Stability of the object's composition
If the air bed is divided into multiple air chambers to improve supporting capability, then stability is improved, but production cost increases
Solution Approach 1:
The patent merges the bottom walls of multiple air chambers into a single common bottom sheet. This shared bottom sheet reduces the total amount of material required compared to constructing separate bottom walls for each chamber. The bottom sheet is designed to accommodate all air chambers while minimizing material usage and simplifying production.
3Stability of the object's composition
If structural pull belts are added to improve stability, then supporting capability is improved, but device complexity increases
Solution Approach 1:
The patent places structural pull belts at specific critical locations within the air bed, such as at the corners and along the edges of the air chambers. This localized placement provides maximum structural support where needed most, enhancing stability without requiring pull belts throughout the entire structure. The selective positioning minimizes added complexity while achieving the desired supporting capability.
