Tire Innerliner RFID Assembly With Perforated Rubber Substrate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The embedding of RFID tags and antennas within the innerliner of tires during the manufacturing process can lead to air or gas trapping, causing blisters that compromise the structural integrity and safety of the tire.
Innovation Solution
Attaching the RFID tag and antenna to the surface of the tire's innerliner within a rubber substrate, which is perforated to allow gas escape and uses an adhesive or adhesion promoter to secure the components, reducing the risk of blister formation during the curing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the RFID tag and antenna are embedded into the green tire prior to curing, then electronic data collection capability is improved, but air or gas becomes trapped causing blisters that compromise structural integrity
Solution Approach 1:
The invention separates the RFID tag assembly from the tire curing process by providing it in a separate removable carrier. The carrier allows the RFID tag to be positioned and attached to the tire surface without being embedded into the tire structure, thus avoiding trap air pockets while maintaining electronic functionality.
Solution Approach 2:
The RFID tag is extracted from the embedding process and provided as a separate component on a removable carrier. This allows the tag to be attached to the tire surface without being incorporated into the cured tire structure, eliminating the cause of blisters while preserving the electronic data collection function.
2Duration of action of stationary object
If the RFID tag and antenna are embedded into the green tire, then the tag remains attached for the life of the tire, but blisters form during curing that compromise safety
Solution Approach 1:
The RFID tag is attached to the tire surface in advance using a removable carrier before the curing process begins. This preliminary attachment allows the tag to be in place for data collection while avoiding the embedding step that causes blister formation during curing.
Solution Approach 2:
A removable carrier acts as an intermediary between the RFID tag and the tire surface. The carrier enables initial attachment and positioning during manufacturing, then can be removed after curing to prevent interference with the final tire structure and eliminate blister formation.
