Solution Overview

Problem

There is a need for voice and data recording systems on the ground to support incident and accident investigation for unmanned aerial vehicles (UAVs), as existing technologies do not adequately address the requirements for regulatory activities and safety analysis in civilian UAV operations.

Innovation Solution

Control station audio and data recording systems are implemented, comprising an audio packetizer processing unit, audio storage unit, and audio playback unit for capturing and storing audio communications, and a data processing unit, data storage unit, and data playback unit for recording and storing vehicle data, allowing for time-stamped and tagged data retrieval for analysis.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If ground-based voice and data recording systems are implemented for UAV operations, then incident investigation capability is improved, but system complexity increases

Engineering Contradiction:
Improveincident investigation capabilityVSAvoidrecording system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The recording system is divided into separate functional modules: audio packetizer processing unit for voice recording, data processing unit for telemetry data, audio storage unit, data storage unit, audio playback unit, and data playback unit. Each module performs a specific function, making the overall system more manageable and less complex while maintaining comprehensive incident investigation capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces control stations as intermediary devices that receive and process audio and data packets from UAVs before storing them. The control stations act as mediators between the UAVs and the final storage systems, simplifying the direct recording burden and enabling centralized management of recording operations across multiple platforms.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If comprehensive audio and data packet information is stored for multiple vehicles, then analysis thoroughness is improved, but data storage requirements increase

Engineering Contradiction:
Improveanalysis thoroughnessVSAvoiddata storage volume
Core Design Contradiction:
Loss of informationVSQuantity of substance

Solution Approach 1:

The system extracts and stores only essential information elements: audio packets containing voice communications with timestamps and vehicle identifiers, and data packets containing telemetry information with corresponding metadata. By extracting only the critical data elements needed for incident analysis rather than storing all possible data, the system maintains analysis thoroughness while managing storage requirements.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent transforms continuous audio and data streams into discrete packetized information with specific parameters (timestamps, vehicle IDs, packet types). This parameterization allows efficient storage and retrieval of key information points without storing entire continuous datasets, reducing storage volume while preserving analytical value.

Inventive Principle:
Principle #35Parameter changes
