Solution Overview
Problem
Existing inflatable beds with multiple air chambers have a cumbersome and inefficient manufacturing process due to the need for through holes in the inclined pull strap, which weakens the structure and shortens the service lifetime.
Innovation Solution
A novel inflatable bed design featuring a closed annular pull strap with broken portions in the weld seam, allowing for one-step welding and communication between air chambers, enhancing tensile strength and manufacturing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If through holes are provided on the inclined pull strap to communicate multiple air chambers, then the air chambers can be in communication, but the manufacturing process becomes cumbersome and the tensile strength is weakened
Solution Approach 1:
The patent merges the functions of the pull strap and the air chamber communication structure into a single integrated component. The pull strap itself forms the communication channels between air chambers without requiring separate through holes, simplifying the manufacturing process to one-step welding while maintaining chamber communication capability.
Solution Approach 2:
The pull strap serves multiple functions simultaneously: it strengthens the bed body structure, provides communication between air chambers, and acts as a structural support element. This multi-functionality eliminates the need for separate components and reduces manufacturing complexity.
2Adaptability or versatility
If through holes are provided on the inclined pull strap, then the air chambers can be in communication, but the tensile strength is weakened and service lifetime is shortened
Solution Approach 1:
The communication channels are integrated into the pull strap structure itself rather than being created as separate through holes. This merging maintains the structural integrity and tensile strength of the pull strap while still enabling air chamber communication.
Solution Approach 2:
The pull strap is segmented into multiple regions that form communication channels, allowing air flow between chambers while maintaining the overall structural strength of the strap through strategic placement of these segments.
3Adaptability or versatility
If through holes are provided on the inclined pull strap, then the air chambers can be in communication, but the manufacturing efficiency is reduced
Solution Approach 1:
The pull strap and communication structure are merged into a single component that can be welded in one step, eliminating the need for separate hole-making operations and significantly improving manufacturing efficiency.
Solution Approach 2:
The communication channels are pre-formed as part of the pull strap structure before assembly, allowing for one-step welding and eliminating subsequent processing steps, thereby improving manufacturing productivity.
4Ease of manufacture
If a single air chamber is used, then the production process is simple and manufacturing is easy, but the bed is easy to collapse at edges and use effect is not ideal
Solution Approach 1:
The single air chamber is segmented into multiple air chambers that work together to provide both manufacturing simplicity and edge stability. The segmented structure distributes support across multiple chambers while maintaining overall structural integrity.
Solution Approach 2:
Multiple air chambers are merged into a unified structure with integrated pull straps, combining the benefits of multi-chamber stability with simplified manufacturing processes through one-step welding technology.
