Solution Overview
Problem
Current tire pressure monitoring systems (TPMS) require manual intervention for sensor type identification and communication protocol adaptation, leading to inefficiencies and incompatibilities across different vehicle brands and models, necessitating specific readers and operator expertise.
Innovation Solution
A reading bench equipped with an optical sensor for vehicle identification, a radio communication unit, and an electronic module that automatically detects and adapts to the communication protocol of TPMS sensors by analyzing the vehicle's license plate and database information, allowing for automatic detection and adaptation of communication parameters such as transmission power and protocol.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual readers are used for TPMS sensor reading, then operator control and sensor type identification are possible, but operation time increases and compatibility across different vehicle brands is limited
Solution Approach 1:
The reading bench automatically identifies the vehicle brand, model, and sensor type through optical character recognition of the license plate and database lookup, eliminating the need for manual sensor type identification by the operator. The system self-configures the appropriate communication protocol and reading parameters based on the identified vehicle characteristics.
Solution Approach 2:
The system performs preliminary identification of the vehicle and sensor type before the actual reading process begins. By recognizing the license plate and querying the database in advance, the reading bench pre-configures all necessary communication parameters and protocols, so that when the reading process starts, no manual intervention or time-consuming configuration is needed.
2Adaptability or versatility
If multiple manual readers are equipped for different manufacturers, then compatibility with various vehicle types is improved, but device complexity and cost increase
Solution Approach 1:
The reading bench is designed as a universal system that can read TPMS sensors from any vehicle brand and model. Instead of requiring separate dedicated readers for different manufacturers, this single device automatically adapts to different vehicle types by recognizing the license plate, querying the database for vehicle-specific parameters, and configuring the appropriate communication protocol dynamically.
Solution Approach 2:
The reading bench dynamically adjusts its operation mode, communication protocol, and reading parameters based on the identified vehicle characteristics. The system transitions from a static, manufacturer-specific configuration to a dynamic, vehicle-adaptive configuration, allowing one device to perform the functions of multiple dedicated readers.
3Ease of operation
If manual positioning and communication configuration is used, then precise sensor reading is possible, but ease of operation decreases and operator expertise is required
Solution Approach 1:
The system automatically determines the optimal reading position, communication protocol, and parameters by analyzing the vehicle type and sensor characteristics through database lookup. This eliminates the need for operators to manually configure complex communication settings or precisely position equipment, while the system maintains accurate sensor readings through automated parameter optimization.
4Reliability
If radio transmission power is increased for reliable communication, then communication reliability improves, but energy consumption and electromagnetic pollution increase
Solution Approach 1:
The reading bench dynamically adjusts the radio transmission power parameter based on the specific sensor type, vehicle characteristics, and communication conditions identified through the database lookup. Instead of using a fixed high power setting, the system optimizes the transmission power to the minimum level required for reliable communication with each specific sensor, thereby reducing energy consumption and electromagnetic pollution while maintaining communication reliability.
