Single-Wire Data Burning for Tire Pressure Monitoring Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tire pressure monitoring systems require two data lines for data transmission and reception, increasing port installation costs and complicating the data burning process, as they need to be initialized properly before programming can begin.
Innovation Solution
A method for burning data into a tire pressure monitoring device using a single wire for electrical connection between a burning tool and the device, enabling two-way communication and reducing the number of required ports through a series of microprocessor instructions and clock calculations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two data lines are used for data transmission and reception, then reliable communication can be achieved, but port installation cost increases and device complexity increases
Solution Approach 1:
The patent combines transmission and reception functions into a single data line. The burning tool and tire pressure monitoring device each have a single data line that serves both for sending and receiving data, eliminating the need for separate dedicated transmission and reception lines. This merging reduces the number of ports required while maintaining bidirectional communication capability.
Solution Approach 2:
The single data line is designed to be universal, serving multiple functions including data transmission, data reception, and device control. The same physical line is used for different communication purposes at different times, making the system more versatile and reducing hardware requirements.
2Reliability
If two data lines are used for data transmission and reception, then data burning can be performed, but the burning process becomes inconvenient and productivity decreases
Solution Approach 1:
The system performs preliminary initialization through the single data line before data burning begins. The burning tool can send initialization commands and receive status information beforehand, ensuring the device is ready for programming without requiring separate setup procedures or additional port configurations.
Solution Approach 2:
The single data line enables real-time feedback during the data burning process. The tire pressure monitoring device can send status information, confirmation signals, and error reports back to the burning tool through the same line used for data transmission, allowing for immediate verification and error handling without interrupting the burning workflow.
