Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aircraft recording systems fail to reliably reproduce onboard instrumentation due to low-quality video recordings, storage capacity limitations, and the time-consuming, error-prone process of reconstructing instrumentation, especially in training environments where accurate and quick reconstruction is crucial.
Innovation Solution
A recording and replay system that records processed aircraft parameters using a mission computer with an operational flight program, allowing for the faithful reconstruction of onboard instruments through a mission data recorder and debriefing system, without relying on video recordings, thereby providing accurate and efficient data retrieval and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video recording is used to capture cockpit instrumentation, then visual documentation is provided, but the recording quality is low and storage requirements are high
Solution Approach 1:
The invention extracts only the essential instrument data parameters from the complex video recording, separating the critical information (instrument readings, alerts, warnings) from the redundant visual content. This extraction process reduces storage requirements while maintaining the ability to accurately reproduce instrumentation.
Solution Approach 2:
Instead of copying actual video images of instruments, the system creates digital replicas of instrument data by capturing and storing structured parameter information. This digital copying method enables faithful reproduction of instrumentation without the storage burden of video files.
2Reliability
If video recording is used to document cockpit instrumentation, then visual evidence is captured, but the reconstruction process is time-consuming and error-prone
Solution Approach 1:
The system performs preliminary structuring and organization of instrument data during the recording phase, preparing the information in advance for easy retrieval and accurate reconstruction. This preliminary action eliminates the need for time-consuming manual analysis during reconstruction.
Solution Approach 2:
The invention replaces the manual mechanical process of video analysis and instrumentation reconstruction with an automated digital system that retrieves and reproduces instrument data directly from stored parameters, significantly reducing time and eliminating human error.
3Reliability
If camera-based systems are used to record cockpit instruments, then visual documentation is provided, but the view may be blocked or blurred
Solution Approach 1:
The system introduces an intermediary digital data representation layer between the physical instruments and the recording medium. Instead of directly capturing visual images that can be obstructed, the system captures instrument parameter data through electrical/ digital interfaces, eliminating the problem of visual obstruction.
4Measurement precision
If detailed instrument data is recorded for accurate reproduction, then faithful reconstruction is achieved, but storage requirements increase
Solution Approach 1:
The system changes the form and organization of stored data from continuous video streams to discrete, structured instrument parameters. This parameter transformation enables efficient compression and storage while preserving the precision needed for accurate instrumentation reproduction.
