Inflatable Product Welding With Isolating Members for Tensioning Structures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for attaching tensioning structures to inflatable products made of weldable plastics do not effectively prevent weldable contact between different portions of the structures, leading to potential defects and reduced product integrity.
Innovation Solution
A method involving high-power, high-frequency welding of tensioning structures to inflatable sheets using an upper and lower die system with isolating members positioned between the structures to prevent weldable contact, ensuring that only the intended portions of the tensioning structures are welded to the sheets while maintaining the structural integrity of the inflatable product.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If tensioning structures are welded to both sheets simultaneously without isolation, then productivity is improved, but manufacturing precision deteriorates due to unintended weldable contact between portions
Solution Approach 1:
An isolating member is introduced as an intermediary element positioned between portions of tensioning structures during the welding process. This isolating member prevents unintended weldable contact between portions while allowing the welding operation to proceed, thus maintaining both productivity and precision
2Manufacturing precision
If isolating members are positioned between tensioning structure portions, then welding precision is improved, but device complexity increases
Solution Approach 1:
The isolating member serves as a simple intermediary component that can be easily positioned and removed, providing precise welding control without significantly complicating the overall device or process
3Productivity
If high-power high-frequency welding is used, then productivity is improved, but harmful factors increase due to potential defects from unintended contact
Solution Approach 1:
The isolating member is positioned in advance between portions of the tensioning structures to prevent unintended weldable contact before the high-power high-frequency welding process begins, thereby eliminating the source of potential welding defects

AI summary
A welding process of an inflatable product is provided that includes using isolating members between first and second portions of weldable tensioning members 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 of weldable material and welding of the second portions to a second sheet of weldable material.
