Tire Innerliner RFID Mounting to Prevent Curing Blisters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The embedding of RFID tags and antennas within the innerliner of tires can lead to blister formation due to trapped air or gases during the curing process, compromising the structural integrity and safety of the tire.
Innovation Solution
Attaching an RFID tag and antenna to the surface of the tire's innerliner within a rubber substrate, which is perforated to allow gas escape and coated with adhesives to secure the components, thereby preventing blister formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RFID tags and antennas are embedded into the green tire prior to curing, then electronic data collection capability is improved, but air or gases become trapped causing blisters to form during curing
Solution Approach 1:
The patent applies preliminary action by creating perforations in the rubber substrate before embedding the RFID tag and antenna. These perforations serve as pre-established escape pathways that prevent gas accumulation during the subsequent curing process, thereby eliminating the blister formation problem while maintaining electronic data collection capability
Solution Approach 2:
The patent extracts the harmful trapped air and gases from the system by providing escape pathways through the perforations in the rubber substrate. This allows the gases to be removed from the enclosed space during curing, preventing blister formation while preserving the RFID functionality
2Strength
If RFID tags and antennas are embedded deep within the innerliner, then attachment security is improved, but blisters form around the embedded components compromising structural integrity
Solution Approach 1:
The patent applies local quality by creating localized perforations specifically around the RFID tag and antenna embedding area within the rubber substrate. This localized approach provides gas escape pathways exactly where needed - around the embedded components - while maintaining secure attachment and preserving the overall structural integrity of the innerliner
Solution Approach 2:
The patent segments the rubber substrate by creating multiple small perforations distributed around the RFID tag and antenna. This segmentation allows gas to escape through multiple small pathways rather than requiring a single large opening, thereby maintaining both attachment security and structural integrity while preventing blister formation

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method ensures the secure attachment of RFID tags and antennas on the tire's surface, reducing the risk of blister formation and maintaining the structural integrity and safety of the tire during the curing process.
Implementation Method 1
the rubber substrate allows the RFID tag and antenna to be securely attached to the innerliner of the tire... by attaching the RFID tag and antenna to the surface of the innerliner of the tire, the risk of blisters forming around the RFID tag and antenna that could impact the structural integrity of the tire is eliminated
Implementation Method 2
coated with adhesives to secure the components, thereby preventing blister formation

AI summary
Disclosed are various approaches to depositing an RFID tag or chip within a rubber substrate. A radio frequency identifier (RFID) chip encapsulated with an adhesive or adhesion promoter is attached to the rubber substrate. Then, a wire antenna is attached to the rubber substrate and inductively coupled to the RFID tag. The wire antenna can be encapsulated with an adhesive or adhesion promoter. The wire antenna can also be arranged longitudinally along the rubber substrate in a plurality of loops with at least one of the plurality of loops placed around the RFID tag.
