Automotive Sensor Module for RFID Service Component Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in verifying whether a service component element installed in an automotive system, such as a filtration system, is genuine or authorized, as non-genuine components can allow contaminants to pass through, potentially damaging downstream components.
Innovation Solution
The implementation of an antenna-based sensor package that communicates with a close-range communication reader to authenticate service component elements by comparing their tag information with a list of verified genuine components, triggering warnings if a non-genuine component is detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If service component elements are replaced periodically to remove contaminants, then filtration effectiveness is maintained, but the risk of installing non-genuine components increases
Solution Approach 1:
The system performs preliminary authentication of the service component element before it is installed in the filtration system. The sensor module reads the tag on the service component element and verifies its authenticity against genuine component data, preventing non-genuine components from being installed in the first place
Solution Approach 2:
The system provides feedback about the authenticity of the installed service component element to the operator. The display device shows whether the component is genuine or non-genuine, and can alert operators to replace non-genuine components, creating a closed-loop verification system
2Reliability
If authentication systems are implemented to verify service component authenticity, then component genuineness is ensured, but system complexity increases
Solution Approach 1:
The authentication functionality is extracted into a separate, standalone sensor module that can be independently added to the filtration system. This modular approach allows the authentication system to be implemented without redesigning the entire filtration system, reducing overall complexity
Solution Approach 2:
The sensor module is designed with multi-functionality, serving both as a standard sensor component and as an authentication device. By integrating tag reading capabilities into a commonly installed sensor module, the system avoids adding separate dedicated authentication hardware, thereby reducing complexity

AI summary
Systems and methods for determining, using service component authenticity detection contained in a sensor module, whether an authorized or genuine service component element is installed in an automotive system are described. The authorized service component determination may be based on close-range communication technology such as radio frequency identification (“RFID”) technology. An antenna in the sensor module may read the tag information from installed service component elements in a nearby service component and send any detected information into a filtration monitoring system. The filtration monitoring system or a remote diagnostic system analyzes the returned data (or absence thereof) to determine if a genuine (i.e., authorized, OEM approved, etc.) service component element is installed or not.
