Inflatable Bed with Integrated Backrest Using Merged Sheet Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inflatable beds with integrated backrests have complex structures and high production costs, often resulting in poor aesthetics and stability issues.
Innovation Solution
The design incorporates an upper sheet with a planar and oblique portion, a lateral confining sheet forming an inflatable chamber, and internal sheets that connect the upper and lower sheets to create a stable backrest while simplifying the structure and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If an integrated backrest structure is used in inflatable beds, then the overall aesthetics and stability are improved, but the structure becomes more complex and production cost increases
Solution Approach 1:
The patent merges the backrest structure with the main body of the inflatable bed by forming the backrest from the same inflatable chamber. The lateral confining sheet extends to form both the side wall of the bed and the backrest, creating an integrated structure that improves stability and aesthetics while reducing structural complexity compared to separate backrest designs
Solution Approach 2:
The lateral confining sheet serves multiple functions: it forms the side wall of the inflatable bed, provides structural support, and extends to form the backrest. This multi-functional design eliminates the need for separate components, reducing production cost and structural complexity while maintaining stability
2Shape
If an integrated backrest structure is used in inflatable beds, then the overall aesthetics are improved, but the structure becomes more complex and production cost increases
Solution Approach 1:
The backrest is merged with the main body through the continuous lateral confining sheet, creating a seamless integrated appearance that improves overall aesthetics while avoiding the complexity of separate backrest components and their associated connection structures
3Device complexity
If a separate backrest is used in inflatable beds, then the structure is simpler, but the overall aesthetics and integration are poor
Solution Approach 1:
The lateral confining sheet is extended to form both the side wall and the backrest in a continuous integrated structure, achieving good overall aesthetics and integration while maintaining relatively simple construction through the use of a single confining sheet component
4Ease of manufacture
If traditional inflatable bed structures are used, then production cost is lower, but stability and backrest support are insufficient
Solution Approach 1:
The backrest is formed as part of the same inflatable chamber as the main body, using the same lateral confining sheet and internal structure. This integrated approach provides improved backrest support stability through unified structural reinforcement while avoiding the need for separate expensive components
Solution Approach 2:
The lateral confining sheet extends in the vertical dimension to form the backrest, creating additional structural support in the height direction. This dimensional extension provides enhanced backrest stability without requiring additional horizontal components, maintaining cost-effectiveness

AI summary
An inflatable bed is provided including an upper sheet, a lower sheet, a lateral confining sheet and a first internal sheet. The lateral confining sheet connects the upper sheet and the lower sheet to define an inflatable chamber. The upper sheet has a planar portion and an oblique portion. The planar portion of the upper sheet is connected to the lower sheet by means of the first internal sheet. The lateral confining sheet comprises a circumferential portion and an extension portion extending upward along an end of the circumferential portion. The extension portion and the oblique portion of the upper sheet are connected to form a backrest of the inflatable bed, and the backrest is internally provided with a second internal sheet which is used for connecting the oblique portion of the upper sheet to the extension portion of the lateral confining sheet. The inflatable bed may further include a third internal sheet, a fourth internal sheet and a fifth internal sheet which are regionally arranged in an inner part to form an integrated backrest.
