Overlapping Water Sport Panel Joint for Waterproof Flexibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water sport article joints face challenges in maintaining flexibility and insulation when panels of varying thicknesses are coupled, leading to increased water penetration and reduced durability due to stitching errors and misalignment.
Innovation Solution
A joint structure is designed with an overlapping interface where panels of varying thicknesses are attached using adhesive bonding, blind stitching, and/or taping, reducing stitching errors and enhancing waterproofness and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If panels of varying thicknesses are attached using conventional stitching methods, then the joint can be formed, but stitching errors and misalignment occur leading to increased water penetration
Solution Approach 1:
An intermediary adhesive layer is introduced between the panels to mediate the bonding process. The adhesive fills gaps and aligns panels of varying thicknesses, preventing stitching errors and ensuring proper alignment, thereby reducing water penetration through the joint.
Solution Approach 2:
The bonding method transitions from purely mechanical (stitching) to a combination of chemical (adhesive bonding) and mechanical methods. This parameter change allows for better accommodation of thickness variations and improves both alignment and waterproofness.
2Adaptability or versatility
If panels of varying thicknesses are attached, then flexibility and insulation can be maintained, but the joint durability is reduced due to misalignment
Solution Approach 1:
The adhesive acts as an intermediary that compensates for thickness differences without compromising durability. It provides a flexible bond that maintains the flexibility benefits of varying panel thicknesses while ensuring proper alignment and long-term joint reliability.
3Reliability
If adhesive bonding is used to attach panels, then waterproofness is improved, but the complexity of the joint structure increases
Solution Approach 1:
The invention merges adhesive bonding with stitching methods into a hybrid joint structure. This combination achieves superior waterproofness while the stitching provides structural reinforcement, balancing complexity with performance benefits.

AI summary
A water sport article (200) is provided. The water sport article includes a joint (208, 301, 702, 802) formed between a first panel (302, 704, 804) having a greater thickness than a second panel (306, 706, 806). The joint includes an overlapping interface (303, 707, 808) between the first and second panels where one or more of adhesive bonding (402, 708), blind stitching (502, 714, 810), and taping (602, 604, 812, 820) is used to attach the first and second panels at the overlapping interface.
