Staggered Reinforcement Ends in Tire Repair Patches
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tire repair patches often detach from the tire due to separation along their edges, particularly in high stress areas like the shoulder and sidewall, leading to air loss and reduced durability.
Innovation Solution
A tire patch with a staggered arrangement of reinforcement endings, where adjacent pairs of reinforcements are axially offset, providing additional stability and resistance to separation, and potentially featuring undulations or alternating patterns to enhance edge reinforcement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional tire repair patches are used with aligned reinforcement endings, then the patch can be easily manufactured and applied, but the patch becomes prone to separation and detachment at the edges in high stress areas
Solution Approach 1:
The reinforcement endings are arranged in a staggered asymmetric pattern rather than being aligned symmetrically. This asymmetry creates interlocking geometry between adjacent reinforcements, preventing edge separation and improving patch reliability in high stress areas without significantly complicating the manufacturing process
Solution Approach 2:
The reinforcement structure is segmented into multiple discrete endings that are offset from each other. This segmentation allows each reinforcement to independently resist separation forces, and the collective staggered arrangement creates a more robust edge structure that maintains attachment reliability
2Duration of action of stationary object
If the patch is designed to resist separation in high stress areas, then durability is improved, but the manufacturing process becomes more complex
Solution Approach 1:
The staggered asymmetric arrangement of reinforcement endings provides inherent resistance to separation forces in high stress areas, extending patch durability. The asymmetry is achieved through simple offset positioning during manufacturing, avoiding complex multi-step processes while maintaining enhanced durability
Solution Approach 2:
The staggered reinforcement arrangement provides localized quality enhancement at the patch edges where separation is most likely to occur. This local structural modification improves durability at critical areas without requiring complex changes to the entire patch structure or manufacturing process

AI summary
A tire patch for repairing an associated vehicle tire includes a patch body configured to overlay a portion of the associated vehicle tire, and a plurality of reinforcements received at least partially within the patch body, each reinforcement of the plurality having a first ending and a second ending, wherein the plurality of reinforcements are arranged to provide a staggered arrangement of the first endings.
