Welding process for producing an inflatable product
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for attaching tensioning structures to inflatable products do not effectively prevent weldable contact between different portions of the structures, leading to potential defects and reduced durability.
Innovation Solution
The use of a high-power, high-frequency welder with an upper and lower die system, along with an isolating member, to simultaneously weld tensioning structures to both sheets of the inflatable product while preventing direct contact between the welded portions, ensuring secure attachment without fusion between the first and second portions of the tensioning structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If tensioning structures are welded to both sheets simultaneously without isolation, then productivity is improved, but welding precision deteriorates due to unintended fusion between portions
Solution Approach 1:
An isolating member is introduced as an intermediary element positioned between the first and second portions of the tensioning structure during the welding process. This mediator prevents direct contact and unintended fusion between the portions while allowing simultaneous welding to both sheets, thus maintaining both productivity and precision
2Manufacturing precision
If isolating members are used to prevent weldable contact, then welding precision is improved, but device complexity increases
Solution Approach 1:
The isolating member is designed to be removable after the welding process completes. The temporary nature of the isolating member during welding reduces long-term device complexity while maintaining welding precision during the critical manufacturing stage
3Manufacturing precision
If traditional sequential welding is used, then welding precision is maintained, but productivity decreases
Solution Approach 1:
The isolating member is pre-positioned between the tensioning structure portions before the welding process begins. This preliminary action enables both welding operations to proceed simultaneously without interference, improving productivity while maintaining the precision that would otherwise require sequential operations

AI summary
A welding process of an inflatable product is provided that includes using isolating members (6) between first and second portions of weldable tensioning members (4) to resist the first and second portions of the weldable tensioning structures being welded together during welding of the first portions to a first sheet (5) of weldable material and welding of the second portions to a second sheet (7) of weldable material.
