Double-layer inflatable bed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing double-layer inflatable beds have high material consumption and cost due to the need for isolation layers between the two inflatable beds.
Innovation Solution
A double-layer inflatable bed design featuring two main layers, two annular peripheral layers, at least one annular connecting layer, and two annular blocking layers, which define a main air chamber and two peripheral air chambers without a middle isolation layer, reducing material usage and cost while enhancing structural strength and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If two inflatable beds are stacked and fixedly connected with isolation layers between them, then structural strength and stability are improved, but material consumption and cost increase
Solution Approach 1:
The patent merges the isolation layer function into the peripheral layers themselves. The peripheral layers serve dual purposes: providing structural support and acting as isolation barriers between the upper and lower inflatable beds. This eliminates the need for separate isolation layers, reducing material consumption while maintaining structural strength.
Solution Approach 2:
The peripheral layers are designed to perform multiple functions simultaneously: they provide structural support for the inflatable bed, act as isolation layers between stacked beds, and define the boundary of the air chamber. This multi-functionality reduces the total number of components needed and lowers material consumption.
2Reliability
If isolation layers are added between stacked inflatable beds, then stability and reliability are improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The isolation function is merged into the peripheral layers that are already necessary for structural support. By combining the isolation function with the existing peripheral layers, the patent avoids adding separate isolation components, thereby maintaining stability while reducing structural complexity.
Solution Approach 2:
The patent extracts the isolation function from being a separate component and integrates it into the peripheral layers. This extraction simplifies the overall structure by eliminating redundant components while maintaining the necessary stability between stacked beds.
3Reliability
If more material is used to create separate isolation layers, then safety and structural integrity are improved, but cost increases
Solution Approach 1:
The peripheral layers are designed to serve multiple functions including structural support, isolation, and safety. By making these layers multi-functional, the patent ensures safety and structural integrity are maintained while avoiding the need for additional material-consuming isolation layers.
Solution Approach 2:
The safety and isolation functions are merged into the peripheral layers. This integration ensures that the same structural components that provide support also provide safety and isolation, eliminating the need for separate material-consuming components.

AI summary
A double-layer inflatable bed includes two main layers arranged in a thickness direction of the double-layer inflatable bed, two annular peripheral layers, annular connecting layers, and two annular blocking layers. The two annular peripheral layers are connected to the two main layers respectively, the two annular peripheral layers are both connected to the annular connecting layers, and the two annular blocking layers are connected to the two main layers respectively; and ends of the two annular blocking layers away from the main layers are both connected to the annular connecting layers, wherein the two main layers and the two annular blocking layers together define a main air chamber, and the two main layers, the two annular peripheral layers, the annular connecting layers, and the two annular blocking layers together define two peripheral air chambers disposed adjacent to each other in a thickness direction of the double-layer inflatable bed.
