Solution Overview
Problem
The existing tire pressure monitoring systems require a complex and costly learning phase when replacing defective sensors, necessitating a visit to a garage for relearning and reprogramming, which is time-consuming and inefficient.
Innovation Solution
A method and device that allow the recording and transfer of a defective sensor's unique identifying number and communication protocol to a new sensor, enabling direct programming and eliminating the need for a learning phase, using low-frequency radio waves and a portable electronic tool to read and store the information, and configure the new sensor without onboard diagnosis system access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a new sensor is installed to replace a defective sensor, then the sensor functionality is restored, but a complex learning phase is required to reprogram the vehicle's onboard system
Solution Approach 1:
The patent applies preliminary action by pre-programming the replacement sensor with the same identification number and communication protocol as the defective sensor before installation. This allows the sensor to be immediately recognized by the vehicle's onboard system without requiring a time-consuming learning phase, thus restoring functionality while eliminating the time loss.
Solution Approach 2:
The patent uses copying by transferring the identification number and communication protocol data from the defective sensor to the replacement sensor. This copying process ensures that the replacement sensor is identical in terms of system recognition, allowing it to seamlessly take over the defective sensor's role without requiring reprogramming of the vehicle's onboard system.
2Adaptability or versatility
If a learning phase is implemented to reprogram the vehicle system, then the new sensor is recognized, but the process requires access to onboard diagnosis systems and specialized equipment
Solution Approach 1:
The patent uses copying to transfer the identification number and communication protocol from the defective sensor to the replacement sensor. This eliminates the need for complex onboard diagnosis systems and specialized programming equipment, as the replacement sensor is already configured to be recognized by the vehicle's standard system.
Solution Approach 2:
The patent applies self-service by enabling the replacement sensor to be pre-configured with the necessary identification and protocol information before installation. This self-configuration allows the sensor to be immediately recognized by the vehicle's onboard system without requiring external programming equipment or complex reprogramming procedures.
3Ease of manufacture
If the sensor's identification number is changed during replacement, then a unique identifier is assigned to the new sensor, but the vehicle system must undergo relearning to recognize the new identifier
Solution Approach 1:
The patent uses copying by transferring the identification number from the defective sensor to the replacement sensor. This maintains the same unique identifier in the system, allowing the vehicle's onboard system to continue recognizing the sensor without requiring relearning, thus simplifying the replacement operation and maintaining high productivity.
Solution Approach 2:
The patent applies preliminary action by pre-configuring the replacement sensor with the same identification number as the defective sensor before installation. This preliminary configuration ensures that the replacement operation is simple and quick, while the vehicle system continues to recognize the sensor without requiring time-consuming relearning procedures.
4Reliability
If a garage visit is required for sensor replacement and reprogramming, then proper equipment is available, but the process becomes costly and time-consuming
Solution Approach 1:
The patent uses copying to transfer the identification number and communication protocol to the replacement sensor before installation. This eliminates the need for a garage visit with specialized equipment, allowing the replacement to be performed quickly and accurately without vehicle downtime, while maintaining reliability through proper sensor configuration.
Solution Approach 2:
The patent applies preliminary action by pre-configuring the replacement sensor with the necessary identification and protocol information before the replacement operation. This allows the replacement to be performed quickly without requiring a garage visit or vehicle downtime, while ensuring accuracy through proper pre-configuration of the sensor.

AI summary
The invention relates to a method of replacing a defective sensor (100) of a surveillance system for monitoring in particular the pressure of the wheels of a vehicle (V) of the type of that comprising: wireless sensors (100) disposed in each wheel and a receiver; a unique identifier number being assigned to each sensor (100) thus making it possible for the receiver to identify the signal. This method is noteworthy in that it consists in: removing the defective sensor (100); identifying and logging the unique identifier number of the defective sensor (100); identifying and logging the communication protocol used on the vehicle; assigning said unique identifier number to a new virgin sensor (200, 200′) with neither assigned communication protocol nor assigned identifier number and simultaneously; programming the new sensor (200, 200′) so that it utilizes said communication protocol. The invention also relates to the device D and the sensor 200 making it possible to implement same. Applications: detection of data available inside the wheels of a vehicle.
