RFID Mesh Label Structure for Tire Vulcanization Bonding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Adhesive-based RFID labels used on rubber-based articles, such as tires, tend to detach during vulcanization and subsequent use due to mechanical stress and flexing, leading to operational issues and inability to maintain identification over the lifetime of the article.
Innovation Solution
RFID mesh labels with a face layer, an RFID layer, and a mesh backing treated with reactive coatings that bond with the rubber during vulcanization, creating a non-flexing zone and ensuring the label remains integral to the tire, allowing for durable and long-lasting identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive-based RFID labels are applied to green rubber-based articles, then identification capability is provided, but the labels detach during vulcanization and subsequent use due to mechanical stress and flexing
Solution Approach 1:
The patent changes the physical and chemical parameters of the label structure by transitioning from a flexible adhesive label to a rigid mesh backing structure with reactive coating. This parameter change enables the label to withstand vulcanization temperatures and mechanical stress, resolving the detachment issue while maintaining identification reliability throughout the article's lifetime
Solution Approach 2:
The patent employs a composite material structure consisting of mesh backing, reactive coating layer, and RFID elements. This composite design combines the structural integrity of mesh materials with the bonding capability of reactive coatings, creating a label that remains attached during vulcanization and throughout the article's service life
2Stability of the object's composition
If the mesh backing is rigid to create non-flex zones, then label stability during flexing is improved, but the label may not conform to the curved surface of the tire
Solution Approach 1:
The patent applies local quality by making only the backing structure rigid while keeping the RFID elements and face layer flexible. This localized rigidity provides structural stability and creates non-flex zones where needed, while allowing other portions to conform to the tire's curved surface, thus resolving both contradictions
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 RFID mesh labels remain attached and operable throughout the tire's lifetime, providing reliable identification and information during production, distribution, and use, while withstanding high temperatures and mechanical stress.

AI summary
An RFID mesh label configured to be integrally incorporated within a vulcanized tire and to further provide unique identifier(s) and/or other information about the vulcanized tire during and/or post-vulcanization, the RFID mesh label including a face layer configured to be positioned adjacent or flush to an outer surface of the vulcanized tire; an RFID layer positioned underneath the face layer, the RFID layer having an RFID device that is configured to provide unique identifier(s) and/or other information about the vulcanized tire upon being read with an RFID reader; and a mesh backing overlying the RFID layer and adapted to be integrally incorporated in a vulcanized tire after subjecting a green tire to a vulcanization process.
