Double-Layer Inflatable Bed with Oblique Ring for Bed Cover Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Double-layer inflatable beds require complex manufacturing processes, high production costs, and often experience issues with bed covers slipping off due to the lack of a special structure for secure placement.
Innovation Solution
A double-layer inflatable bed design featuring a middle piece with an oblique ring and lateral pieces connected through tensioning structures, allowing for a recessed connection that facilitates easier bed cover placement and optimized production efficiency and cost reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an upper inflatable bed and a lower inflatable bed are spliced together using connecting members, then a double-layer inflatable bed is formed, but the manufacturing process becomes complicated and production cost increases
Solution Approach 1:
The patent merges the upper and lower inflatable beds into a single integrated structure where the lateral piece forms a continuous wall between the two air chambers. This eliminates the need for separate connecting members and reduces manufacturing steps while maintaining structural stability.
Solution Approach 2:
The lateral piece serves multiple functions simultaneously: it forms the boundary of the upper air chamber, the boundary of the lower air chamber, and provides the connection between the two layers. This multi-functionality reduces the number of components needed and simplifies the manufacturing process.

3Ease of manufacture
If traditional inflatable bed structure is used, then manufacturing is simpler, but bed cover slips off causing inconvenience
Solution Approach 1:
The patent applies a specific structural feature (the recessed connection formed by the lateral piece) at the location where the bed cover needs to be secured. This local structural modification prevents the bed cover from slipping off while maintaining overall manufacturing simplicity.
4Ease of manufacture
If traditional inflatable bed structure is used, then manufacturing is simpler, but production efficiency is lower
Solution Approach 1:
The patent merges the upper and lower inflatable beds into a single integrated structure where the lateral piece forms a continuous wall between the two air chambers. This eliminates the need for separate connecting members and reduces manufacturing steps while maintaining structural stability.
Solution Approach 2:
The lateral piece serves multiple functions simultaneously: it forms the boundary of the upper air chamber, the boundary of the lower air chamber, and provides the connection between the two layers. This multi-functionality reduces the number of components needed and simplifies the manufacturing process.

AI summary
An inflatable bed is provided, comprising: a first piece, a middle piece having a middle master piece and an oblique ring piece having an inner edge connected to the middle master piece, and a second piece; a first lateral piece connected to the first piece and to an outer edge of the oblique ring piece; and a second lateral piece connected to the middle piece and to the second piece. A first air chamber is defined by the first piece, the middle piece, and the first lateral piece. A second air chamber is defined by the middle piece, the second piece, and the second lateral piece.
