Intermediary Data Transfer for Short-Range Tyre Monitoring Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft tyre pressure monitoring systems face inefficiencies in data transmission due to limited wireless communication range, which can lead to security vulnerabilities and increased time required for manual pressure checks, especially in high-speed environments like aircraft landing gear.
Innovation Solution
A method and system utilizing an intermediary device for data transfer between tyre monitoring devices separated by distances greater than their maximum wireless communication range, employing short-range wireless communication protocols like NFC or RFID for secure key distribution and data transfer, and a control device for coordinating the movement of the intermediary device to facilitate data exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If direct wireless communication is used between tyre monitoring devices, then communication simplicity is maintained, but communication security deteriorates due to limited wireless range requiring extended transmission
Solution Approach 1:
The patent introduces a mobile device as an intermediary to transfer data between tyre monitoring devices. The mobile device receives data from one tyre monitoring device via short-range wireless communication (NFC/RFID) and transmits it to another tyre monitoring device, enabling secure key distribution and data exchange without requiring direct long-range communication between monitoring devices.
2Productivity
If manual tyre pressure checking is performed, then system simplicity is maintained, but time consumption increases due to wheel-by-wheel measurement
Solution Approach 1:
The patent enables configuration data and encryption keys to be copied from one tyre monitoring device to another through the mobile device intermediary. This allows rapid provisioning of multiple monitoring devices without manual configuration of each device individually, significantly reducing setup time while maintaining system security through encrypted short-range communication.
3Reliability
If short-range wireless communication (NFC/RFID) is used for data transfer, then communication security is improved, but communication range deteriorates requiring physical movement of devices
Solution Approach 1:
The patent makes the mobile device dynamic by moving it between different tyre monitoring devices located on various wheels of the aircraft. This dynamic approach allows secure short-range communication to occur at multiple locations without requiring the monitoring devices themselves to be moved or accessible, as the mobile device travels to each location to perform data transfer.

AI summary
A method of copying data from a first device to a second device, each device comprising a wireless communication interfaces having a maximum range, is disclosed. The first device and the second device are separated by a distance greater than the maximum range. The method comprises: transmitting, by the first device, the data to a third device positioned within the maximum range of the first device; receiving the data at the third device and storing the data in a memory of the third device; moving the third device to a physical location within the maximum range of the second device; and transmitting, by the third device, the data to the second device.
