Retreaded Tire RFID Tag Embedding for Peel-Resistant Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for mounting RFID tags on tires without pre-installed tags face issues such as peeling and intentional replacement, and the risk of damage due to strain concentration and radio wave interference from metal components.
Innovation Solution
A production method for retreaded tires that incorporates an RFID tag within a crosslinked rubber protector, positioned radially inward of the belt and with a shorter initial vulcanization time, ensuring the tag is fixed and protected from damage, maintaining a good communication environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an RFID tag is mounted on a tire after manufacturing, then information management capability is added, but the tag is susceptible to peeling and intentional replacement
Solution Approach 1:
The RFID tag is embedded in the uncured rubber composition before the tire curing process, allowing the tag to be automatically fixed and protected during tire manufacturing without requiring separate post-manufacturing operations
Solution Approach 2:
The RFID tag embedding process is merged with the tire curing process, where the rubber composition is applied to the tire surface, the RFID tag is embedded, and then the entire assembly is cured together in a single operation
2Reliability
If the RFID tag is placed near metal components for fixation, then the tag is securely fixed, but radio wave communication is interfered with
Solution Approach 1:
The rubber composition serves as an intermediary material between the RFID tag and the tire structure, providing both mechanical fixation and electromagnetic shielding that prevents radio wave interference while securing the tag in place
Solution Approach 2:
The rubber composition forms a flexible encapsulating layer around the RFID tag, isolating it from metal components and providing electromagnetic protection while allowing the tag to move with the tire deformation
3Reliability
If the RFID tag is positioned on the tread surface for easy access, then mounting is simplified, but the tag is exposed to strain concentration and damage
Solution Approach 1:
The rubber composition provides beforehand cushioning and protection to the RFID tag by encapsulating it within a flexible matrix that absorbs and distributes mechanical strains, preventing concentration of stress on the tag during tire deformation
Solution Approach 2:
The RFID tag is nested within the rubber composition which is itself applied to the tire surface, creating a hierarchical structure where the tag is protected inside the rubber layer rather than being exposed on the surface

AI summary
A method for producing a retreaded tire 2 includes a step of shaving a tread 104 from a tire 102, a step of attaching a tag member 30 to a formed surface BD made by shaving the tread 104, and a step of reconstructing a new tread 4. The formed surface BD is located radially outward of a maximum width position of the tire 2. The tag member 30 is located radially inward of an end of a belt 14. An initial vulcanization time t10 of a rubber composition for a protector 34 of the tag member 30 is shorter than an initial vulcanization time 110 of a rubber composition for the new tread 4.
