Problem
Current laser event recorders are inadequate for aviation purposes as they may not provide accessible data in the event of a crash and are not readily available to pilots, with existing systems lacking wireless transmission capabilities to central servers for comprehensive analysis.
Innovation Solution
A laser event recorder equipped with an image sensor, processing unit, and wireless transceiver that identifies laser illumination, records event characteristics, and sends data to a central server, allowing for analysis even if the device is destroyed, and can be integrated into smartphones for accessibility and cost-effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If laser event data is stored locally in the recorder device, then data is available for immediate access, but data may be lost if the device is destroyed in a crash and cannot be accessed by external systems
Solution Approach 1:
The patent introduces a wireless transceiver as an intermediary component that enables communication between the laser event recorder and external systems. This allows data to be transmitted wirelessly to ground stations or other receivers, ensuring data persistence even if the aircraft recorder is destroyed, while maintaining the local storage capability for immediate access.
2Measurement precision
If specialist laser detection equipment is used, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent applies the universality principle by using a standard image sensor that serves multiple functions: capturing normal visual scenes and detecting laser events through pixel saturation analysis. This eliminates the need for specialized laser detection hardware while maintaining detection capability, thereby reducing device complexity and cost without sacrificing measurement precision for laser event detection.
Solution Approach 2:
The patent uses a copy of the visual scene captured by the image sensor to detect laser events. By analyzing the saturation pattern in the captured image data, the system can identify laser events without requiring dedicated laser detection sensors, thus simplifying the overall device architecture while maintaining detection accuracy.
3Reliability
If fixed storage systems are used in aircraft, then data security is improved, but accessibility to recorded data is reduced
Solution Approach 1:
The patent introduces dynamic data transmission capabilities through the wireless transceiver, allowing the system to adapt between secure local storage and flexible wireless data transmission. This dynamic approach enables data to be securely stored locally when needed while also allowing easy accessibility through wireless communication when required, resolving the contradiction between security and accessibility.
