Solution Overview

Problem

Existing aircraft recording systems fail to reliably reconstruct onboard instrumentation due to low-quality video recordings and high storage requirements, leading to time-consuming and error-prone debriefing processes, 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 faithful reconstruction of onboard instruments without video, and includes a mission debriefing system to reproduce the instrumentation based on these parameters, reducing storage needs and improving debriefing efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If video recording is used to capture cockpit instrumentation, then visual documentation of instruments is achieved, but storage capacity requirements become excessively high and recording quality degrades

Engineering Contradiction:
Improveinstrumentation documentation qualityVSAvoidstorage capacity requirements
Core Design Contradiction:
Loss of informationVSQuantity of substance

Solution Approach 1:

The patent extracts only the essential instrument data parameters from the complex video recording, separating the critical instrumentation information from the redundant visual content. This allows storing only the necessary data points (flight parameters, instrument readings) without the bulk video footage, directly resolving the storage capacity issue while preserving documentation quality.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of copying actual video images of instruments, the system creates digital replicas of instrument data through structured parameter recording. The mission computer generates precise digital representations of instrument states, which can be reconstructed during debriefing without requiring the original video footage, thus eliminating storage constraints.

Inventive Principle:
Principle #26Copying

2Loss of information

If video recording is used to document cockpit instrumentation, then visual records are obtained, but reconstruction becomes time-consuming and error-prone

Engineering Contradiction:
Improveinstrumentation accuracyVSAvoiddebriefing time
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The system performs preliminary organization of instrument data during flight recording, structuring parameters and timestamps as they are captured. This pre-processed data is ready for immediate retrieval and reconstruction during debriefing, eliminating the need for time-consuming manual analysis of video footage and reducing reconstruction errors.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The mission computer acts as an intermediary between the flight instrumentation and the recording system. It directly interfaces with instrument sensors and processors, capturing data in a structured format that can be easily reconstructed, rather than relying on indirect video documentation that requires manual interpretation and increases error risk.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Quantity of substance

If only aircraft parameters are recorded for instrument reconstruction, then storage requirements are reduced, but faithful reconstruction of onboard instrumentation becomes unreliable

Engineering Contradiction:
Improvestorage capacityVSAvoidinstrumentation reconstruction accuracy
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The mission computer serves multiple functions: it controls flight operations, processes instrument data in real-time, and simultaneously records the data in a reconstruction-ready format. This multi-functionality ensures that the recorded parameters are both storage-efficient and sufficiently detailed for faithful instrument reconstruction, bridging the gap between compact storage and reliable reconstruction.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system transforms raw instrument data into optimized parameter representations that maintain reconstruction fidelity while reducing storage requirements. By changing the data format from verbose video descriptions to structured numerical parameters with precise timestamps, the system achieves both compact storage and reliable reconstruction capability.

Inventive Principle:
Principle #35Parameter changes
