Tire Sidewall Lateral Deformation for Inner Surface Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for accessing and repairing the inner surface of a tire face challenges due to the curvature of the tire sidewall, which restricts access for tools and requires support to resist applied forces during operations like buffing or patch application.
Innovation Solution
A method and apparatus that laterally deform the tire sidewall by constraining the bead and sidewall from moving towards each other, using an inclined member to increase the sidewall's curvature, allowing easier access and better support for operations by maintaining the sidewall in a flatter, more laterally expanded configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the tire sidewall maintains its natural curved configuration, then the tire structure remains intact and stable, but access to the inner surface is restricted and tools cannot be effectively introduced
Solution Approach 1:
The sidewall is dynamically deformed from its static curved configuration into a laterally expanded configuration using an inclined member and actuating device. This dynamic transformation allows the sidewall to transition between its natural stable state and a deformed state that provides improved access to the inner surface for repair operations.
Solution Approach 2:
The physical parameters of the sidewall are changed by laterally expanding it, which alters its curvature and orientation. This parameter change transforms the sidewall from a tightly curved configuration that blocks access to a more open, laterally expanded configuration that facilitates tool introduction and inner surface operations.
2Ease of manufacture
If tools are introduced into the tire cavity to perform operations on the inner surface, then repair functions can be performed, but forces are applied to the sidewall that require support to prevent deformation
Solution Approach 1:
The inclined member acts as an intermediary between the actuating device and the sidewall. It provides a controlled interface that applies lateral force to expand the sidewall while maintaining stability during repair operations. The inclined member supports the sidewall in its deformed configuration, preventing unwanted deformation when tools apply forces to the inner surface.
Solution Approach 2:
The sidewall is laterally expanded and supported in advance before repair operations begin. This preliminary action creates a stable, accessible configuration that can withstand the forces applied during subsequent buffing, patch application, or sensor installation without deforming during the actual repair process.
3Ease of operation
If the bead and sidewall are allowed to move freely toward each other, then the tire maintains its compact natural form, but the sidewall cannot be laterally deformed to improve access
Solution Approach 1:
The constraining function is extracted as a separate, dedicated component rather than being integrated into the main deformation mechanism. The bead constraining member is a distinct element that specifically prevents the bead and sidewall from moving toward each other, allowing the inclined member and actuating device to focus on lateral deformation without complexity from combined functions.

Function Achieved in This Case
The lateral expansion of the tire sidewall increases access to the inner surface, allowing for more effective tool introduction and improved resistance during operations, enhancing the performance of tire repair and maintenance tasks.
Implementation Method 1
