TPMS Display Device Multi-Protocol Sensor Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tire pressure monitoring systems (TPMS) are limited by their inability to communicate and function across different original equipment manufacturer (OEM) protocols, leading to compatibility issues between OE and aftermarket systems, which restricts their effectiveness in monitoring tire conditions uniformly across vehicles.
Innovation Solution
A tire pressure monitoring device equipped with a processor that selects and converts signals from sensors using different communication protocols based on vehicle-specific or tire-specific information, allowing it to receive and display temperature and pressure data from sensors of various OEMs, and includes a power unit compatible with vehicle power sources like USB ports.

Engineering Contradiction Analysis
1Reliability
If conventional TPM systems use specific OEM protocols for communication, then the system can function reliably with its designated sensors, but the system cannot communicate or function with sensors from other manufacturers
Solution Approach 1:
The TPM display device is designed to support multiple communication protocols simultaneously, enabling it to communicate with sensors from different OEMs. The device includes a database of protocols from multiple manufacturers and can select appropriate protocols based on sensor identification, making the system universally compatible while maintaining reliable communication with each sensor type.
Solution Approach 2:
The TPM display device acts as an intermediary between sensors with different OEM protocols and the user interface. It receives data from various sensor protocols, converts and standardizes the information, and presents unified tire condition data to the user, mediating between incompatible communication systems.
2Ease of operation
If the TPM system is designed to work with a specific OEM's sensors, then the communication function is optimized for that manufacturer, but the system cannot display or process data from sensors of other manufacturers
Solution Approach 1:
The TPM display device dynamically adapts its communication protocol based on the detected sensor type. Upon receiving a sensor signal, the system identifies the OEM protocol being used and automatically switches to the appropriate communication mode, enabling seamless operation with different manufacturer sensors without manual configuration.
Solution Approach 2:
The system changes communication parameters such as protocol type, data format, and processing methods based on the detected sensor manufacturer. This parameter adaptation allows the same hardware to efficiently communicate with diverse sensor types while maintaining optimized performance for each protocol.

AI summary
A tire pressure monitoring device includes a display, a receiver, a memory, and a processor. The receiver is configured to receive a first signal from a first sensor and a second signal from a second sensor. The memory stores a first and second communication protocols corresponding to the first and second sensors, respectively. The processor is in communication with the display, the receiver, and the memory and is configured to perform operations. The operations include selecting the first and second communication protocols based on the first and second signals, respectively, converting the first and second signals into first and second sets, respectively, of at least one of temperature data or pressure data corresponding to a first tire, and transmitting the first set and the second set of at least one of temperature data or pressure data to the display.
