Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tire pressure monitoring systems are limited in their ability to seamlessly integrate and communicate with different original equipment manufacturer (OEM) and aftermarket protocols, leading to compatibility issues and inefficient sensor management.
Innovation Solution
A system and method that programmatically assigns and manages communication protocols to tire pressure sensors, allowing for the transmission of multiple protocols and determining the status of the power source and memory based on these protocols, enabling compatibility with various OEM and aftermarket systems, and includes features like protocol retrieval from a database and payment processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional TPM systems use specific communication protocols for each OEM or aftermarket system, then protocol compatibility within each system is maintained, but the system cannot seamlessly integrate and communicate with multiple different OEM and aftermarket protocols
Solution Approach 1:
The system enables a single TPM sensor to perform multiple communication functions by storing and executing multiple different communication protocols in its memory. The sensor can be programmed with various OEM and aftermarket protocols, allowing it to adaptively communicate with different receiver systems without requiring separate dedicated sensors for each protocol type.
Solution Approach 2:
The system introduces dynamic protocol selection where the communication protocol is not fixed but can be changed and updated. The TPM sensor can receive protocol updates and switch between different protocols based on the requirements of different receiver systems, making the system flexible and adaptable to various communication standards.
2Adaptability or versatility
If multiple communication protocols are stored and managed in the TPM sensor, then protocol versatility is improved, but the memory requirements and power consumption increase
Solution Approach 1:
The system pre-loads and stores multiple communication protocols in the TPM sensor's memory during manufacturing or initial programming. This preliminary action allows the sensor to have multiple protocols readily available without requiring large amounts of memory to be allocated dynamically, as the protocols are prepared in advance and stored efficiently.
3Reliability
If the system determines status of power source and memory based on communication protocols, then accurate sensor management is achieved, but the processing time and energy consumption increase
Solution Approach 1:
The system implements feedback mechanisms where the status of the power source and memory is continuously monitored and determined based on the active communication protocol. This feedback allows the system to adaptively manage resources, ensuring accurate sensor management while optimizing processing efficiency by only performing status determinations when necessary.

AI summary
A system for programming a tire pressure sensor includes data processing hardware and memory hardware in communication with the data processing hardware. The memory hardware stores instructions that when executed on the data processing hardware cause the data processing hardware to (i) transmit at least one communication protocol to the tire pressure sensor, and (ii) determine a status of at least one of a power source of the tire pressure sensor or a memory of the tire pressure sensor based on the at least one communication protocol.
