Tyre Module Position Assignment Using RFID Tire Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire pressure monitoring systems for commercial vehicles face challenges in accurately and efficiently assigning tire modules to their respective positions on the vehicle.
Innovation Solution
A method involving vehicle tires with transponders containing identification codes and RFID chips, where the vehicle drives past a receiving device to read and store these codes, allowing for automatic and secure assignment of tire modules to specific positions using a central data memory and radio communication for data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual assignment methods are used to assign tire modules to tire positions, then the assignment process can be completed, but the process is time-consuming and prone to errors
Solution Approach 1:
The patent replaces manual mechanical assignment processes with an automated electronic identification system. Transponders embedded in tires and receiving devices that read these transponders automatically identify and assign tires to positions, eliminating manual intervention and significantly reducing assignment time while improving accuracy.
Solution Approach 2:
The tire modules self-identify through embedded transponders that contain unique identification codes. When a tire is mounted on the vehicle, the transponder automatically transmits its identification to the receiving device, which then automatically assigns the tire to the correct position without requiring manual input or intervention.
2Extent of automation
If transponders with RFID chips are embedded in each tire, then automatic identification and assignment can be achieved, but the device complexity increases
Solution Approach 1:
The transponder system serves multiple functions: it provides unique tire identification, stores tire information, enables automatic position assignment, and facilitates tire change detection. This multi-functionality justifies the added complexity by consolidating what would otherwise require multiple separate systems into a single integrated component.
Solution Approach 2:
The transponder acts as an intermediary between the tire and the vehicle's monitoring system. It contains the identification information and communicates it to the receiving device, serving as a bridge that enables automatic recognition and assignment without requiring direct complex interaction between the tire and vehicle systems.
3Ease of operation
If the vehicle drives past receiving devices for transponder reading, then assignment can be performed without stopping the vehicle, but the assignment process takes longer at high speeds
Solution Approach 1:
The system uses periodic scanning of transponders as the vehicle passes receiving devices at regular intervals. The receiving devices continuously scan for transponders, and when a transponder is detected, the assignment process is triggered. This periodic action allows the system to function effectively at various vehicle speeds without requiring the vehicle to stop.
