Tyre Life Cycle Management via Embedded RFID and Sensor Fusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for managing the life cycle of tires, such as using bar codes, two-dimensional codes, and RFID chips, are ineffective due to wear and tear, power source limitations, and misreading issues, making real-life cycle and intelligent management of tires impossible.
Innovation Solution
An apparatus comprising a tire state detector and a data processor that detects tire state parameters, generates life cycle management information by correlating identity identifiers, usage scenarios, and date, using low-frequency excitation signals, pressure, temperature, and acceleration sensors, and integrates bar code, two-dimensional code, and RFID chip information for comprehensive tire management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bar code or two-dimensional code is used for tyre identification, then the identification can be implemented, but the code is easily worn on the tyre surface resulting in inability to be recognized in later stages
Solution Approach 1:
The identification code is embedded within the tyre structure during manufacturing, nested inside the tyre rather than placed on the surface. This protects the code from wear and tear while maintaining accessibility for reading throughout the tyre's service life.
Solution Approach 2:
The identification code is pre-installed and protected within the tyre structure before the tyre enters service. This preliminary embedding ensures the code remains intact and readable throughout the entire tyre lifecycle, avoiding the wear problems of surface-applied codes.
2Adaptability or versatility
If low-frequency RFID chip is used for tyre identification, then the chip can be integrated with the tyre, but the chip lacks power source and relies on tool stimulation requiring close proximity or inside access to read
Solution Approach 1:
The RFID chip operates frequency is changed to high-frequency or ultra-high-frequency range, which enables passive chips to be read from greater distances without requiring physical access to the chip location, thus improving ease of reading while maintaining integration benefits.
3Ease of operation
If high-frequency or ultra-high frequency RFID chip is used, then the reading distance is extended, but multiple tyres may be stimulated causing misreading
Solution Approach 1:
The system applies local quality by providing individualized identification codes and implementing selective reading strategies for each tyre position and scenario, enabling precise identification even when multiple tyres are in the reading field, thus resolving the misreading issue while maintaining extended reading distance.
4Ease of operation
If manual reading device is used for tyre identification, then the device can read the identification, but real life cycle management and intelligent management of tyre cannot be achieved
Solution Approach 1:
The system implements automated feedback loops where tyre identification and state data are continuously collected, processed, and used to trigger appropriate management actions. This automation enables real-life cycle management and intelligent decision-making without relying on manual reading devices.
Solution Approach 2:
The tyre management system operates autonomously by automatically detecting, reading, and processing tyre identification and state information, then making management decisions without human intervention. This self-service capability achieves real-life cycle management and intelligent operation.
