Layered Tire Repair Patch Sizing for Reliable Damage Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional repair patches for vehicle tires require a large number of different dimensions to be manufactured and stocked, leading to complex production processes and user complexity due to extensive damage tables, resulting in increased effort and reduced reliability.
Innovation Solution
A repair patch with adjustable external dimensions and intermediate layers, where the number and size of layers are determined by a dimension quotient based on the damaged area, simplifying production and application by reducing the number of required semi-finished products and streamlining damage tables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large number of repair patches with different dimensions are manufactured and kept in stock, then reliable repair for all tire damage sizes is ensured, but production complexity and inventory requirements increase significantly
Solution Approach 1:
The patent applies universality by designing a single repair patch that can serve multiple damage sizes through adjustable intermediate layers. The patch can be configured with different numbers and dimensions of intermediate layers to match various damage areas, allowing one patch design to fulfill multiple repair functions that previously required many different patch types.
Solution Approach 2:
The patent applies segmentation by dividing the repair patch into multiple intermediate layers that can be selectively removed or adjusted. This segmentation allows the patch to be adapted to different damage sizes by configuring the number and dimensions of intermediate layers, eliminating the need to manufacture and stock many different complete patch types.
2Adaptability or versatility
If a large number of different semi-finished products are kept for production, then all damage scenarios can be covered, but manufacturing effort and time increase
Solution Approach 1:
The patent applies dynamics by making the patch configuration adjustable rather than fixed. The number and dimensions of intermediate layers can be dynamically adapted to match the specific damage size, allowing a single production line to produce patches for various damage scenarios without requiring multiple dedicated production lines for different patch types.
3Reliability
If complex damage tables with many patch types are used, then all damage areas can be matched, but user complexity and selection difficulty increase
Solution Approach 1:
The patent applies parameter changes by using a dimension quotient (ratio between patch external dimensions and damaged area dimensions) as the key selection criterion. Instead of navigating complex tables with many patch types, users only need to calculate this simple ratio and select the corresponding patch configuration, significantly simplifying the selection process while maintaining accurate matching.

AI summary
The invention relates to a repair patch for an elastomer material, in particular for a vehicle tire, to the use of the repair patch, and to a method for repairing a vehicle tire. The repair patch has a cover layer 10, a connection layer 30 to be placed on a damaged area 60 of the elastomer component 40, and at least one intermediate layer 20 which is arranged between the cover layer and the connection layer. The repair patch 1 has outer dimensions such that a dimension quotient which is formed at least by means of at least one size parameter of the damaged area 60 lies within a specified value range, and the number of intermediate layers 20 depends on the at least one size parameter of the damaged area 60.
