Additive-Retaining Repair Sheet for Faster Tire Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tire repair methods require significant time and effort, such as removing and replacing tire parts, which is inefficient.
Innovation Solution
A repair sheet with a retaining layer having a breaking strength of 0.5 MPa or more and a breaking elongation of 5% or more, capable of retaining additives, is used to facilitate tire repair by attaching to the tire part and supplying additives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional tire repair methods are used (removing and replacing tread parts), then tire repair can be achieved, but significant time and effort are required
Solution Approach 1:
The invention extracts the essential repair function from the complex process of removing and replacing tread parts. Instead of physically removing the old tread and installing a new one, the repair sheet is applied to the existing tire surface, extracting only the necessary additive supply function while eliminating the time-consuming mechanical operations.
Solution Approach 2:
The repair sheet acts as an intermediary carrier that delivers additives to the tire rubber. Rather than directly modifying the tire structure through complex operations, the repair sheet mediates the repair process by supplying additives that restore tire performance, significantly reducing the time and effort required.
2Strength
If the retaining layer has high breaking strength, then structural integrity is maintained, but flexibility and ability to follow tire part may be reduced
Solution Approach 1:
The invention specifies parameter ranges for the retaining layer: breaking strength of 0.5 MPa or more and breaking elongation of 5% or more. These parameter changes define the optimal balance between strength and flexibility, allowing the layer to maintain structural integrity while adapting to tire deformations during use.
Solution Approach 2:
The retaining layer is composed of specific materials (thermoplastic elastomer, resin, or crosslinked rubber) that provide both required strength and flexibility. These composite material choices enable the layer to simultaneously achieve high breaking strength and sufficient elongation, resolving the contradiction between structural integrity and adaptability.
3Ease of operation
If simple repair sheet attachment is used, then processing effort is reduced, but adequate additive retention and supply may not be achieved
Solution Approach 1:
The retaining layer is designed with porous structure that enables it to retain additives while maintaining flexibility. The porosity allows the layer to hold sufficient additive quantity for effective tire treatment, while the overall simple attachment structure maintains ease of operation. The porous structure provides both additive retention capacity and operational simplicity.
