Retread Tire RFID Placement for Retreading Durability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need to improve the usefulness of tires by embedding a communication device in a position that considers the retreading process.
Innovation Solution
A retreaded tire with a communication device, such as an RFID tag, is embedded at specific positions within the tire structure that avoid interference and damage during retreading, ensuring continuous use and improved maintainability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a communication device is embedded in a tire, then the tire's functionality and traceability are improved, but the device may be damaged or interfered with during retreading processes
Solution Approach 1:
The patent positions the communication device in the radial direction between the tread and belt layers, and in the width direction outside the tread width, creating a three-dimensional placement that avoids interference from retreading operations while maintaining tire functionality
Solution Approach 2:
The communication device is embedded in the green tire before the tread is attached, allowing the device to be positioned in a protected location that avoids damage during subsequent retreading processes
2Stability of the object's composition
If a communication device is embedded in a tire at a conventional position, then the tire structure is maintained, but the device cannot withstand retreading processes
Solution Approach 1:
The patent specifies precise positional coordinates for the communication device in both radial and width directions, placing it in a region that maintains tire structural integrity while being excluded from retreading operation zones
Solution Approach 2:
The patent creates a localized protected region for the communication device by positioning it outside the tread width and between specific radial layers, giving this local area different functional properties (protected vs. processed)
3Ease of operation
If the communication device is positioned close to the tread surface, then it is easily accessible, but it is vulnerable to damage during retreading
Solution Approach 1:
The patent uses three-dimensional positioning with the device located between the tread and belt layers radially, and outside the tread width laterally, creating spatial separation from harmful retreading operations while maintaining operational accessibility
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The communication device remains functional and easily maintainable throughout multiple retreading cycles, enhancing the tire's usefulness and productivity.

AI summary
A tire comprises: a belt composed of one or more belt layers; a main groove on a tread surface; and a communication device embedded at a position that is inward in a tire radial direction from a groove bottom of the main groove, outward in the tire radial direction from an inner surface of an innermost belt layer in the belt, and outward in a tire width direction from a minimum width belt layer in the belt, wherein a tire radial outer side of the communication device is not covered with the belt.
