Inflatable Product Welding With Isolating Members for Clean Tensioning Joints
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 an isolating member positioned between the structures to prevent weldable contact, ensuring that only the intended portions of the tensioning structures are welded to the sheets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If tensioning structures are welded to inflatable sheets using high-power high-frequency welding, then secure attachment is achieved, but unwanted weldable contact between different portions of the structures occurs causing defects
Solution Approach 1:
An isolating member is positioned between portions of the tensioning structures during the welding process. This intermediary component prevents unwanted weldable contact between different portions of the tensioning structures while allowing the intended welding to proceed, thereby eliminating defects and ensuring product integrity without compromising attachment strength
2Reliability
If isolating members are positioned between tensioning structures to prevent unwanted welds, then product integrity is enhanced, but device complexity increases
Solution Approach 1:
The isolating members are positioned between portions of the tensioning structures before the welding process begins. This preliminary action ensures that unwanted weldable contact is prevented from the outset, eliminating the need for complex real-time control mechanisms during welding and simplifying the overall process while maintaining product integrity

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.
