Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual copying of flight instructions from EFB to FMS is used, then data transfer can be performed, but the crew workload increases and time is lost during flight preparation
Solution Approach 1:
The patent replaces the manual mechanical copying process with an automated optical recognition system. The EFB generates optical symbols (QR codes or barcodes) containing flight instruction data, which the onboard optical reader automatically scans and transfers to the FMS, eliminating manual typing and copying operations.
Solution Approach 2:
The patent uses optical symbols as digital copies of flight instruction data. Instead of manually copying text data, the system creates compact optical representations (QR codes, barcodes) that contain all necessary flight information, enabling rapid automated transfer from ground EFB to onboard FMS.
2Reliability
If manual data entry is used, then flight instructions can be transferred, but input errors occur and crew efficiency decreases
Solution Approach 1:
The patent replaces manual data entry with automated optical recognition and data transfer. The optical reader automatically scans and transfers flight instructions to the FMS, eliminating human typing errors and improving both accuracy and ease of operation.
Solution Approach 2:
The system performs self-service data transfer where the optical reader automatically reads and transfers flight instructions without requiring crew intervention for data entry. The FMS automatically processes the received data, reducing crew workload and improving operational ease.
3Productivity
If optical symbol generation and reading system is implemented, then data transfer speed increases and workload decreases, but system complexity increases
Solution Approach 1:
The patent uses compact optical symbols (QR codes, barcodes) as efficient data carriers. These optical copies encode flight instruction data in a condensed format that can be rapidly read and processed, achieving high transfer speeds without requiring complex communication infrastructure.
Solution Approach 2:
The patent introduces optical symbols as an intermediary medium between the ground EFB and onboard FMS. This intermediate optical carrier format simplifies the overall system architecture by providing a universal, easily implementable data transfer mechanism that balances speed and complexity.
