Aircraft Data Exchange Device Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for exchanging data between a ground-based storage system and an aircraft's onboard storage system are inefficient, leading to prolonged immobilization of the aircraft on the ground and high costs due to slow data transfer via communication networks and risks of outdated data when using USB sticks or hard discs.
Innovation Solution
A method involving synchronization of data through a communications network, followed by coupling with the aircraft's local internal network for direct data transfer, ensuring authentication and secure data exchange, allowing for rapid and reliable data updates without relying on third-party communication links.

Engineering Contradiction Analysis
1Speed
If data transfer is performed via communication networks (Wi-Fi, 3G/4G, satellite), then data exchange can be achieved, but the transfer speed is too slow and causes prolonged aircraft immobilization on the ground
Solution Approach 1:
The data transfer process is segmented into two distinct phases: (1) preliminary synchronization of the data exchange device with the ground-based storage system via communication network before aircraft arrival, and (2) rapid direct synchronization between the data exchange device and onboard storage system via USB connection after aircraft arrival. This segmentation allows the time-consuming network transfer to occur beforehand, while the actual aircraft data exchange uses fast direct connection.
Solution Approach 2:
The data exchange device performs preliminary data synchronization with the ground-based storage system through the communication network before the aircraft arrives. This preliminary action ensures that the latest data is already available in the data exchange device, so that when the aircraft connects, only a quick verification and minimal transfer are needed, dramatically reducing immobilization time.
2Ease of operation
If wireless communication links of third party operators are used for data transfer, then data exchange can be achieved, but significant costs are incurred to the operators
Solution Approach 1:
The data transfer operation is divided into two segments with different cost structures: (1) preliminary synchronization using communication network (incurs cost but done before aircraft arrival), and (2) main data transfer using USB connection (no third-party cost). This segmentation shifts the cost-bearing operation to occur before the aircraft arrives, making the actual aircraft data exchange cost-free.
Solution Approach 2:
The data is copied to the data exchange device in advance through the communication network. This copy is then used for rapid transfer to the aircraft via USB connection, eliminating the need to pay for transferring the same data through expensive wireless links during aircraft operations.
3Speed
If data transfer is performed via USB stick or hard disc, then fast transfer speed is achieved, but there is a risk that the data do not correspond to the last updated version
Solution Approach 1:
The system implements automated feedback mechanisms including data comparison protocols that verify whether the data in the data exchange device matches the latest version in the ground-based storage system, and confirmation protocols that ensure the aircraft receives the correct data version. This feedback ensures data accuracy while maintaining fast transfer speeds.
Solution Approach 2:
The data exchange device automatically performs preliminary synchronization with the ground-based storage system before the aircraft arrives, ensuring that the latest data version is already available. This preliminary action eliminates the risk of transferring outdated data while maintaining fast USB transfer speeds during the actual aircraft data exchange.

AI summary
A method for exchanging data between a storage system on the ground-based and an onboard storage system of an aircraft is provided. The method includes a first step for synchronization of a set of data contained in the ground-based storage system with a corresponding set of data of a storage memory of a data exchange device, through a communications network, a step for coupling the data exchange device to a local internal network of the aircraft connected to the storage system, and then a second step for synchronization of the set of data of the storage memory with a corresponding set of data of the onboard storage system, through the local internal network.
