Temporary Tire Bead RFID Label for Long-Range Warehouse Reading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The handling of large TBR tires in warehouses and production lines is inefficient due to the need for manual reading of RFID devices, which requires operators to step away from forklifts and move readers close to each tire, leading to time wastage and potential damage to temporary RFID devices.
Innovation Solution
A tire with a temporary identification label that supports a readable RFID device, positioned on the tire's bead core to avoid shielding and allow for distant reading, reducing the need for manual intervention and enhancing reading efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an identification label with a temporary RFID device is applied on the tread of the tire, then the RFID device can be read from a greater distance compared to incorporated RFID devices, but the clamp made of metal can cover and shield the RFID device, or even destroy it
Solution Approach 1:
The identification label is moved from the tread surface to the bead core region of the tire, changing the spatial dimension and position. This relocation places the RFID device inside the tire structure where it is protected from external metal clamps while maintaining readable access through the tire materials.
Solution Approach 2:
The RFID device is nested within the tire structure at the bead core region, embedded inside the tire rather than placed on the external surface. This nesting protects the RFID device from external shielding objects like clamps while allowing electromagnetic signals to penetrate through the tire materials for reading.
2Reliability
If two identification labels are applied on the tread at approximately 90° relative to one another, then at least one identification label remains free when the stack is laterally clamped, but this solution doubles costs
Solution Approach 1:
The identification label is relocated from the tread surface to the bead core region, changing its spatial position. This single repositioning eliminates the need for multiple labels while ensuring continuous reading availability, as the internal position is not blocked by lateral clamping operations.
Solution Approach 2:
The single identification label at the bead core serves multiple functions: it provides reliable RFID reading capability regardless of clamp position, reduces manufacturing costs by eliminating the need for duplicate labels, and simplifies the application process while maintaining operational reliability.
3Loss of information
If operators use a manual reader to read RFID devices, then they can access tire information, but operators have to step off the forklift and move the reader close to each tire, leading to time wastage
Solution Approach 1:
The manual reading process is replaced with an automated reading system. The RFID reader is integrated into the forklift or handling equipment, automatically detecting and reading the identification labels on tires without requiring operators to manually approach each tire, thereby eliminating time wastage while maintaining information access.
Solution Approach 2:
The RFID reading system operates autonomously without requiring manual intervention. As tires are moved or positioned by the forklift, the integrated reader automatically detects and reads the identification labels, allowing the system to serve itself in terms of data collection without operator involvement in the reading process.
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
This solution enables efficient and distant reading of tire RFID devices, reducing handling time and minimizing the risk of RFID device damage, while maintaining cost-effectiveness and ease of manufacturing.
Implementation Method 1
RFID devices (wherein RFID stands for 'Radio Frequency Identification'—typically transponders), which allow items of information, such as the identification, the features and the story of the tire, to be communicated from a distance

AI summary
A tire comprises a toroidal carcass, which has a central cavity and at least one body ply, which is partially folded onto itself and, hence, laterally has two turn-ups, each having an edge of the body ply resting against an intermediate portion of the body ply. Two annular beads are each surrounded by the body ply and having a bead core and a bead filler. An identification label is fixed in a removable manner, for example by gluing, and arranged in the area of an annular bead and supports a temporary RFID device, which can be read from a distance.
