Tyre Monitoring Data Relay Using a Mobile Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft tyre pressure monitoring systems require manual data transmission, which is time-consuming due to the need to travel between wheels, and lack secure data distribution methods for sensitive information like configuration data and encryption keys.
Innovation Solution
A method and system utilizing a third intermediary device with short-range wireless communication to transfer data between tyre monitoring devices beyond their individual communication ranges, enhancing security by requiring physical proximity and using different wireless technologies for secure key exchange and data distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual tyre pressure checking is performed, then measurement precision is maintained, but loss of time increases due to travel between wheels
Solution Approach 1:
The patent introduces an intermediary device that acts as a mobile data carrier between tyre monitoring devices. This intermediary stores data temporarily and enables transfer between devices that are beyond direct communication range, thereby eliminating the need for physical travel to each wheel while maintaining secure data transmission.
Solution Approach 2:
The patent creates copies of tyre monitoring data in the intermediary device's memory. The original data remains in the tyre monitoring device while a copy is stored in the intermediary, allowing simultaneous access and transfer without affecting the source data or requiring physical movement to the actual tyre location.
2Productivity
If wireless data transmission is used for tyre pressure monitoring, then productivity is improved by reducing manual checking time, but reliability decreases due to potential data interception
Solution Approach 1:
The intermediary device serves as a secure relay point for data transmission. By routing data through this controlled intermediary rather than direct peer-to-peer wireless communication, the system maintains productivity while adding a layer of security - the intermediary can verify and manage data transfers, reducing interception risks.
Solution Approach 2:
The patent extracts sensitive data transmission from the public wireless domain by using short-range wireless communication (such as NFC) that requires physical proximity. This extracts the security vulnerability from the system, allowing high-speed data transfer while limiting interception to only those in immediate physical contact with the device.
3Reliability
If short-range wireless communication is used for secure data transfer, then reliability is improved by limiting interception risks, but device complexity increases due to multiple wireless interfaces
Solution Approach 1:
The intermediary device is designed with multi-functionality, incorporating both short-range wireless communication capabilities and data storage functions in a single device. This universal approach allows the same device to handle secure communication and data buffering, reducing overall system complexity despite the addition of short-range wireless interfaces.
Data Source
AI summary
A method of copying data from a first device to a second device, each device including 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 includes: 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.
