Tyre Bead RFID Label Placement for Stacked Tyre Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing RFID-based identification systems for tyres are inefficient and costly due to the need for multiple temporary labels, shielding issues, and manual operation, which leads to time wastage and potential damage to RFID devices during handling.
Innovation Solution
A tyre with integrated permanent RFID devices and removable temporary RFID devices positioned on the bead core, allowing efficient reading from a distance using a single antenna, even when stacked, and reducing the need for multiple labels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If an identification label with a temporary RFID device is applied on the tread of the tyre, then the reading distance is increased, but the RFID device can be shielded or destroyed by metal clamps during handling
Solution Approach 1:
The temporary identification label with RFID device is extracted from the tread area and repositioned to the bead core area, removing it from the zone where metal clamps contact the tyre during forklift handling, thus preventing shielding and physical damage while maintaining readable access
2Reliability
If two identification labels are applied on the tread at 90° to each other, then the RFID devices are protected from shielding by clamps, but the costs are doubled
Solution Approach 1:
The identification label is moved from the two-dimensional tread surface to the bead core area, utilizing a different spatial dimension and location that is not interfered with by lateral clamping operations, allowing a single label to suffice without requiring redundant labels
3Measurement precision
If the forklift operator manually reads each tyre's RFID device, then accurate identification is achieved, but time is wasted and manual intervention is required
Solution Approach 1:
The system enables automated identification where the RFID reader on the forklift automatically reads the temporary RFID devices on the tyres without requiring the operator to manually approach and read each tyre, allowing simultaneous reading of multiple tyres and eliminating manual intervention time
4Measurement precision
If the antenna of the reader is moved around the stack of tyres, then all temporary RFID devices can be read, but the operation becomes complex and time-consuming
Solution Approach 1:
The identification labels are pre-positioned on the bead core area where they will be naturally visible to the reader antenna during normal forklift operation, eliminating the need for subsequent manual repositioning or movement of the antenna to access different faces of the tyre stack
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
Enables efficient, automated, and cost-effective identification of stacked tyres with reduced risk of damage, enhancing reading distance and reducing manual intervention.
Implementation Method 1
so-called 'smart' tyres were developed, which are provided with 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 tyre, to be communicated from a distance

AI summary
A tyre (2) having : a toroidal carcass (8), which has a central cavity (6) and consists of at least one body ply (9), which is partially folded onto itself and, hence, laterally has two turn-ups, each having an edge of the body ply (9) resting against an intermediate portion of the body ply (9); two annular beads (10), each surrounded by the body ply (9) and having a bead core and a bead filler (12); and an identification label (19), which is fixed in a removable manner by means of gluing, is arranged in the area of an annular bead (10) and supports a temporary RFID device (20), which can be read from a distance.
