Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire pressure monitoring systems face challenges such as magnetic interference from steel wheels, the need for a separate magnet for calibration, and the requirement for additional tools, which can lead to system inoperability and increased costs.
Innovation Solution
A modular tire pressure monitor system module that includes a stand-alone tool with functionality for transmitting, receiving, resetting, diagnosing, and simulating tire pressure sensor signals, allowing for communication with the vehicle's electronic control unit and enabling accurate tire location identification without the need for a separate magnet, and compatible with various vehicle types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a magnet is used for calibration to initiate tire pressure monitor system, then the system can identify tire locations, but magnetic interference from steel wheels causes system inoperability
Solution Approach 1:
The patent removes the magnet component from the calibration tool, extracting the source of magnetic interference from the system. The calibration process is redesigned to use RF communication instead of magnetic fields, eliminating the harmful magnetic interference from steel wheels while maintaining the ability to initiate and calibrate tire pressure monitor systems.
Solution Approach 2:
The patent replaces the mechanical/magnetic calibration approach with an electronic/RF-based system. Instead of using a magnet to physically interact with the tire monitor, the system uses RF signals transmitted from a calibration tool to communicate with the tire pressure sensors and initiate calibration through wireless communication, substituting magnetic field interaction with electromagnetic wave communication.
2Ease of operation
If a separate magnet and additional tools are required for calibration, then tire location identification can be achieved, but device complexity and cost increase
Solution Approach 1:
The patent combines the calibration functionality with the existing tire pressure monitor system. The calibration tool integrates RF transmission, reception, and processing capabilities within a single unified system that communicates with both the vehicle's electronic control unit and the tire pressure sensors, eliminating the need for separate magnet and additional calibration tools.
Solution Approach 2:
The calibration tool is designed with multi-functionality, serving as both a diagnostic device and a calibration instrument. It can transmit calibration signals, receive tire pressure data, identify tire locations, and communicate with the vehicle's electronic control unit, replacing multiple specialized tools with a single universal device.
