Wireless Tyre Pressure Error Indication for Aircraft Wheels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft tyre pressure monitoring systems require manual checks, which are time-consuming, and existing automated systems still face inefficiencies due to the need to travel between wheels for measurement, and there is a lack of clear error indication in case of device failure.
Innovation Solution
A tyre monitoring system with wireless communication interfaces, indicators, and processors that allow for error detection and indication by non-response to commands, enabling fail-safe operation and efficient data sharing among devices to identify and address errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual tyre pressure checking is used, then measurement accuracy is maintained, but time consumption increases
Solution Approach 1:
The patent replaces manual mechanical pressure checking with an automated wireless sensor system. Sensors mounted on wheel hubs continuously monitor tyre pressure and transmit data wirelessly to a control device, eliminating the need for manual gauges and reducing check time while maintaining measurement accuracy through electronic sensing.
Solution Approach 2:
The tyre pressure monitoring system operates autonomously without requiring manual intervention. Sensors automatically measure pressure, process data locally, and transmit information wirelessly, enabling the system to serve itself and providing continuous monitoring without human involvement in the measurement process.
2Loss of time
If automated wireless sensing is implemented, then measurement time is reduced, but error detection capability deteriorates
Solution Approach 1:
The control device receives wireless transmissions from sensors and provides feedback by displaying status indicators. When a sensor fails to transmit or sends erroneous data, the system detects the anomaly and displays an error status, creating a closed-loop feedback mechanism that maintains reliability while using automated sensing.
Solution Approach 2:
Instead of having sensors actively report errors, the system inverts the approach by expecting regular successful transmissions and treating failures to communicate as error conditions. This inversion simplifies error detection by using the absence of expected data as the error indicator.
3Measurement precision
If individual wheel measurement is performed, then measurement precision is maintained, but operational efficiency decreases
Solution Approach 1:
The patent combines multiple individual tyre monitoring functions into a single integrated wireless network. All wheel sensors communicate simultaneously through a common wireless protocol to a central control device, merging individual measurement operations into a unified system that maintains precision while improving operational efficiency through parallel data collection.

AI summary
A tyre monitoring device and method is described in which an error in a tyre monitoring device can be detected and indicated. A tyre monitoring device comprises an indicator and a wireless communication interface. A method of operating the tyre monitoring device comprises: receiving an instruction to measure a tyre pressure via the wireless communication interface; measuring a tyre pressure; determining an error status of the tyre pressure monitoring device; and responsive to a determination that the error status is not indicative of an error, activating the indicator to provide an indication based on the tyre pressure.
