Wireless USB Data Transfer for Aircraft Database Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current database loading systems for aircraft, such as the DBU-5000, require physical insertion and removal of USB media for data transfer, leading to inefficiencies, vulnerability to virus contamination, and inability to update or monitor content remotely.
Innovation Solution
A wireless-enabled data transferring system using master and slave wireless USB elements that establish secure communication for data transfer between a storage device and an aircraft database loading unit, allowing for secure, remote, and efficient data updates without physical media transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If physical USB media is used for data transfer, then data can be transferred between storage device and aircraft system, but the media must be physically transported and inserted/removed which is time-consuming and inefficient
Solution Approach 1:
The patent replaces the mechanical USB media insertion/removal system with a wireless communication system. The wireless USB element establishes wireless communication channels to transfer data between the storage device and aircraft system, eliminating the need for physical media transport and manual insertion/removal operations.
Solution Approach 2:
The wireless USB element acts as an intermediary device that bridges the storage device and aircraft system through wireless communication. It manages the data transfer process, authentication, and communication protocols, replacing the direct physical connection requirement with an intermediate wireless communication layer.
2Reliability
If removable USB media is used, then data can be transferred, but the media is vulnerable to virus contamination and cannot be monitored from remote locations
Solution Approach 1:
The patent extracts the data transfer function from the physical USB media and relocates it to a wireless communication system. The wireless USB element separates the data transmission function from the physical storage media, allowing data to be transferred without requiring removable media that can carry viruses.
Solution Approach 2:
The wireless USB element enables remote monitoring and management capabilities where the system can receive feedback about data transfer status, authentication states, and system conditions. This allows for real-time monitoring and control of data operations without physical media handling.
3Ease of operation
If USB media is inserted into DBU, then data can be loaded, but the content cannot be updated while inserted and must be physically removed for updates
Solution Approach 1:
The patent implements a dynamic data transfer system where the wireless USB element can establish and maintain multiple communication channels simultaneously. This allows the system to update data content without physical removal, as the wireless connection enables continuous or intermittent data exchange while the system remains operational.
4Quantity of substance
If physical USB media is used, then data transfer is possible, but the USB drive has limited storage capacity and must be available for inspection
Solution Approach 1:
The wireless USB element provides multiple functions including data transfer, authentication, remote monitoring, and system management capabilities. It serves as both a communication interface and a management tool, replacing the single-function physical USB media with a multi-functional wireless system.
Data Source
AI summary
A wireless enabled data transferring system for transferring data from a storage device to a slave receiving system. The wireless enabled data transferring system includes a master wireless USB element connectable to a USB port of a storage device. A slave wireless USB element is connectable to a USB port of a slave receiving system. The master wireless USB element and the slave wireless USB element are operably connected to provide data transfer when i) power is applied, ii) the master wireless USB element and the slave wireless USB element are within a predetermined range, and iii) security authentication is established. The slave wireless USB element emulates the data in the storage device as local to the slave wireless USB element.
