Tire Pressure Sensor Protocol Locking via Pressure Threshold
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire pressure sensor devices face errors and mistaken settings due to non-directional wireless transmission, leading to incorrect configuration of communication protocols during installation.
Innovation Solution
A method where the tire pressure sensor device is installed and started, with the main control processor matching detected tire pressure values to a reference value, allowing protocol adjustments only if the pressure is below the reference, and locking the protocol once the standard pressure is reached, preventing further alterations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless transmission is used for setting the tire pressure sensor device, then the setting operation can be performed remotely and conveniently, but error setting or alteration of setting by mistake may occur during the setting operation
Solution Approach 1:
The system applies preliminary anti-action by implementing a confirmation mechanism before finalizing the communication protocol setting. When a setting signal is received, the system sends a confirmation request to verify the operator's intent, and only proceeds with the setting change after receiving explicit confirmation. This prevents accidental or erroneous settings while maintaining the convenience of wireless operation.
2Adaptability or versatility
If the tire pressure sensor device accepts wireless setting signals continuously, then the device can be configured flexibly, but the device may receive setting signals intended for other devices and be altered by mistake
Solution Approach 1:
The system employs feedback by implementing a two-way communication protocol where the sensor device responds to setting signals with confirmation requests. The setting tool must receive and process these feedback signals before the actual setting change occurs. This feedback loop ensures that only intentional settings are applied while preventing interference from signals intended for other devices.
Solution Approach 2:
The confirmation mechanism acts as an intermediary between the setting signal reception and the actual setting application. Rather than directly applying settings upon reception, the system introduces a verification step that mediates the setting process, ensuring that only confirmed settings are implemented and preventing erroneous alterations.
3Adaptability or versatility
If the communication protocol can be altered after installation, then the device can be reconfigured for different applications, but the existing setting may be altered by mistake
Solution Approach 1:
The system implements dynamic setting management where the communication protocol can be changed during the warranty period through confirmed wireless operations. The confirmation mechanism enables controlled adaptability, allowing legitimate reconfiguration while preventing accidental changes. This dynamic approach balances reconfiguration capability with setting stability.

AI summary
A tire pressure sensor device setting method includes the step of: installing the tire pressure sensor device in a tire and starting it up, the step of enabling the main control processor (10) to match the detected tire pressure value with a predetermined tire pressure reference value, the step of enabling the main control processor (10) to accept a wireless signal from the receiver (17) for altering the communication protocol of the tire pressure sensor device if the detected tire pressure value is greater than the tire pressure reference value, and the step of stopping the main control processor from receiving a wireless signal from the receiver so that the communication protocol of the tire pressure sensor device is locked up to finish the installation.
