Tire Pressure Monitor Tool Protocol Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire pressure monitoring systems face challenges such as the need for a separate magnet for calibration, which can be lost, interference from steel wheels, and the requirement for a separate tool for interfacing with tire pressure monitor systems, leading to inefficiencies and inoperability.
Innovation Solution
A handheld tire pressure monitor system tool that stores communication protocols and allows users to input vehicle data to identify and communicate with tire pressure monitor systems, determining the appropriate protocol for communication with the vehicle's electronic control unit and enabling calibration and diagnostic procedures without the need for a separate magnet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate magnet is used for calibration, then the tire pressure monitor system can be calibrated, but the magnet can be lost causing the system to become inoperable
Solution Approach 1:
The patent combines the calibration magnet function directly into the tire pressure monitoring system tool itself, eliminating the need for a separate magnet. The tool integrates both the calibration capability and the diagnostic/communication functions in a single device, preventing loss of calibration components while maintaining all necessary functions.
Solution Approach 2:
The tire pressure monitor system tool is designed to perform multiple functions: it serves as both the calibration tool (replacing the separate magnet) and the diagnostic/communication tool for interfacing with the vehicle's electronic control unit. This multi-functional design eliminates the need for multiple separate tools and components.
2Adaptability or versatility
If a separate tool is used for interfacing with tire pressure monitor systems, then communication can be established, but it requires additional tools and increases complexity
Solution Approach 1:
The tool is designed with universal communication capabilities that can interface with various tire pressure monitor systems and vehicle electronic control units. It stores multiple communication protocols and can adapt to different vehicle makes and models, eliminating the need for separate diagnostic tools while maintaining broad compatibility.
Solution Approach 2:
The tool acts as an intermediary device between the vehicle's electronic control unit and the user/external systems. It translates and communicates data between different protocols and formats, enabling seamless integration and communication without requiring additional specialized tools.
3Strength
If steel wheels are present, then the vehicle structure is strong, but they cause interference with the calibration process
Solution Approach 1:
The patent replaces the traditional magnetic calibration method with an electronic/communication-based calibration approach. Instead of using a magnet that must physically interact with the tire pressure sensor (which is blocked by steel wheels), the system uses electronic communication protocols to calibrate and communicate with the sensors, eliminating the interference problem caused by steel wheels.
