Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tire pressure monitoring systems (TPMS) require manual and individual programming of sensors, which is error-prone, time-consuming, and inefficient due to different transmission formats used by various automobile manufacturers.
Innovation Solution
A TPMS wheel unit or programming tool that records and replays transmissions, identifying and updating only changing data, allowing for cloning without specific protocol programming and eliminating the need for scan tools, thereby supporting multiple protocols and resolutions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual and individual programming of TPM sensors is performed, then the transmission format can be customized for each automobile manufacturer, but the programming process becomes error-prone, time-consuming, and inefficient
Solution Approach 1:
The patent applies the copying principle by capturing and storing reference transmission data from a first TPM sensor, then replaying this recorded data to program a second TPM sensor. This eliminates manual programming by creating a reusable template that can be copied across multiple sensors, significantly improving programming efficiency while maintaining format accuracy.
Solution Approach 2:
The system performs preliminary action by pre-capturing and storing the reference transmission data in memory before the actual programming of the second sensor occurs. This advance preparation allows the programming process to be rapid and automated, eliminating the need for time-consuming manual configuration each time a sensor needs to be programmed.
2Reliability
If manual programming of TPM sensors is performed, then specific protocol requirements can be met, but the process becomes error-prone and time-consuming
Solution Approach 1:
By copying the exact reference transmission data that is already known to be protocol-compliant, the system ensures that the programmed sensor will follow the same correct protocol format. This eliminates human error in manual programming while maintaining full protocol compliance, as the copied data is replayed exactly as captured from a working sensor.
Solution Approach 2:
The system uses self-service by automatically capturing, storing, and replaying transmission data without requiring manual intervention. The TPM programming device autonomously performs the programming task by replaying the recorded reference data, eliminating the need for operators to manually configure each sensor and thereby reducing both errors and programming time.
3Adaptability or versatility
If different transmission formats are used by various automobile manufacturers, then compatibility with specific vehicles is achieved, but the programming complexity increases
Solution Approach 1:
The programming device achieves universality by being able to program TPM sensors for multiple different automobile manufacturers and transmission formats. By storing reference data for various protocols and replaying the appropriate one based on the target vehicle type, the single device can serve multiple functions across different manufacturers, reducing the need for multiple specialized programming tools.
Data Source
AI summary
A first data transmission and a second data transmission from a TPMS monitor are received and stored. The first data transmission and the second data transmission are compared and at least one changing portion of the data transmission is identified based upon the comparison. Sensed data is received from a tire pressure sensor. A data resolution is determined and a third data transmission formed. The at least one changing portion of the third data transmission is replaced with the sensed data according to the resolution. The third data transmission is transmitted including the sensed data.
