Tire Electronic Device Data Reading via Restricted Bit Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire identification methods, such as serial numbers and DOT numbers, are prone to damage from natural agents and wear, and can be fraudulently altered, making it difficult to manage fleets of vehicles effectively.
Innovation Solution
An electronic device integrated into the tire stores data in a restricted range of bits, allowing for reliable decoding of the serial number and manufacturing week number, which are protected from damage and alteration, and can be encoded using a specific format to simplify the manufacturing process and facilitate data management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data are stored in traditional sidewall markings, then identification is possible, but the data are vulnerable to damage from natural agents, wear, and fraudulent alteration
Solution Approach 1:
The patent creates a digital copy of the identification data stored in an electronic device (RFID tag, data matrix code, or acoustic label) embedded in the tire, replacing the physical sidewall markings. This electronic copy maintains all identification information (serial number, DOT number, manufacturing dates) in a protected digital format that cannot be damaged by natural agents or wear affecting rubber surfaces
Solution Approach 2:
The patent introduces an electronic data storage device as an intermediary between the tire and the identification system. This intermediary stores all identification data electronically and can be read by appropriate devices, eliminating the need for direct reading of vulnerable sidewall markings while providing a protected medium that resists environmental damage
2Reliability
If sidewall markings are used for identification, then tire identification is possible, but the markings can be fraudulently altered by moulding a new layer of rubber
Solution Approach 1:
The patent replaces physical sidewall markings with an electronic digital copy of the identification data. This electronic copy stored in RFID tags, data matrix codes, or acoustic labels cannot be fraudulently altered by adding rubber layers, as the data is stored in a protected electronic medium that requires specialized equipment to modify, making fraud significantly more difficult
Solution Approach 2:
The patent substitutes the mechanical sidewall marking system (molded into rubber) with an electronic data storage and retrieval system. This replacement eliminates the vulnerability to mechanical fraud (molding new rubber layers) by using electronic media that are not susceptible to such physical manipulation
3Reliability
If comprehensive tire data are stored in electronic devices, then reliable identification is achieved, but the device complexity increases
Solution Approach 1:
The patent uses universal electronic data storage formats (RFID tags, data matrix codes, acoustic labels) that can store multiple types of tire identification data (serial number, DOT number, manufacturing dates) in a standardized manner. These multi-functional electronic devices replace multiple separate identification systems, reducing overall complexity while maintaining comprehensive data storage
Solution Approach 2:
The patent combines multiple identification data elements (serial number, DOT number, manufacturing dates) into a single electronic data storage device embedded in the tire. This merging of multiple identification functions into one integrated electronic system reduces complexity compared to having separate physical markings for each data element
Data Source
AI summary
A method is provided for reading data relating to a tire, in which the data is stored in an electronic device integrated into the tire, and in which the tire is identified by a serial number and a manufacturing week number. A storage unit of the electronic device includes a data storage zone having a storage range formed of a number of bits. The storage range is also referred to as a restricted range, and the number of bits of the restricted range is less than or equal to 38. According to the method, the data stored in the restricted range is read, and the data read from the restricted range is decoded in order to determine the serial number and the manufacturing week number of the tire.
