Systems for internal airbed structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional airbeds face issues with internal tensioning structures that add weight, bulk, and rigidity, making them cumbersome to fold and store, and do not provide a desired appearance or prevent over-inflation effectively.
Innovation Solution
An internal structure comprising a sheet or plurality of connection strips attached to the top and bottom surfaces of the air mattress, forming a web-like configuration that maintains the airbed's shape, prevents over-inflation, and reduces lateral movement between surfaces, while being lightweight and easy to store.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional internal tensioning structures (strips with strands of string or wire) are used, then the airbed achieves its intended shape and prevents over-inflation, but the airbed's overall weight increases and it becomes cumbersome to fold up and store
Solution Approach 1:
The patent replaces conventional rigid tensioning strips with a flexible mesh sheet made of thin film material. The mesh sheet is attached to the inner surfaces of the airbed's top and bottom walls, forming a lightweight yet effective tensioning structure that maintains the airbed's shape without adding significant weight or bulk when deflated.
2Stability of the object's composition
If conventional internal tensioning structures (strips with strands of string or wire) are used, then the airbed achieves its intended shape and prevents over-inflation, but the airbed becomes cumbersome to fold up and store
Solution Approach 1:
The mesh sheet is made of flexible thin film material that can be easily folded and compressed when the airbed is deflated, significantly improving storage ease compared to rigid conventional tensioning structures.
3Stability of the object's composition
If rigid internal structures are used, then the airbed maintains its shape effectively, but the appearance and foldability are compromised
Solution Approach 1:
The mesh sheet is constructed from flexible film material that conforms to the airbed's contours and can be easily folded, improving both appearance and storage characteristics compared to rigid conventional structures.
4Stability of the object's composition
If conventional internal structures are used, then shape maintenance is achieved, but the structure adds bulk and weight that complicates transportation
Solution Approach 1:
The mesh sheet is made of lightweight thin film material that provides effective shape maintenance while adding minimal weight to the airbed, significantly improving portability compared to conventional rigid tensioning structures.

AI summary
An air mattress (100) comprises an internal structure (200) for helping the air mattress (100) maintain a desired geometric shape when inflated and for preventing shearing of the top and bottom surfaces (110, 115) of the mattress (100). The internal structure (200) comprises a plurality of connection strips (210) or a mesh web (610) that are attached to a plurality of top surface connection points (215) and bottom surface connection points (225).
