Pilot Vision Protection Against Laser Threats
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to effectively protect pilots from laser threats during critical phases of flight, as current regulatory measures and laser protection goggles are inadequate in preventing distraction or permanent harm from various colored laser beams.
Innovation Solution
A selectively filtered vision protection system with a frame and pivotable light control film or louvers that restricts light from entering the pilot's field of view, adjustable between modes to allow unrestricted viewing when no threat is detected and to block hazardous light during threats, using a detection module to activate the filter mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional laser protection goggles are used, then pilots are protected from laser threats, but vision clarity and field of view are degraded due to opacity
Solution Approach 1:
The patent employs a dynamic filter system that can change its light transmission properties in real-time. The filter transitions between clear and opaque states based on laser threat detection, allowing pilots to maintain clear vision during normal operations while automatically gaining protection when threats are detected. This dynamic adaptability resolves the contradiction between protection and vision clarity.
Solution Approach 2:
The system changes the optical parameters of the filter (transparency, light transmission) in response to detected laser threats. By modifying the filter's transmission characteristics dynamically rather than maintaining a fixed opaque state, the system provides protection only when necessary, preserving vision clarity during normal flight conditions.
2Object-affected harmful factors
If regulatory measures and restrictions are implemented, then laser attacks may be discouraged, but effectiveness is insufficient against intentional and accidental shining
Solution Approach 1:
The protection system is self-activating through automatic laser detection and filter engagement. Rather than relying on external regulatory compliance or pilot awareness, the system autonomously detects laser threats and implements protection, ensuring reliable operation regardless of human factors or regulatory enforcement.
Solution Approach 2:
The system incorporates a feedback mechanism where laser detection triggers filter activation. The detection module continuously monitors for laser threats, and upon detection, signals the filter to transition to a protective state, creating a closed-loop system that reliably responds to threats.
3Object-affected harmful factors
If a pivotable light control film is used, then light blocking capability is improved, but device complexity increases
Solution Approach 1:
The pivotable light control film introduces a simple mechanical degree of freedom that enables effective light blocking when activated. The pivoting mechanism allows the filter to transition between positioned states for blocking and repositioning, providing enhanced protection capability with relatively simple mechanical movement rather than complex multi-component systems.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively reduces the impact of laser threats by blocking hazardous light while maintaining clear vision for pilots, even during critical flight phases, without the opacity issues of traditional laser protection methods.
Implementation Method 1
The privacy filter regulates the angle of the field of view of the user in at least on orthogonal plane. The viewing angle is selected to prevent light transmitted from a light source from being viewed by the user.
Implementation Method 2
The system may further comprise a detection module for detecting an output from the light source. Detecting the output from the light source may generate a first signal that is transmitted to the hinge mechanism to move into the first position.

AI summary
Provided is a selectively filtered vision protection system for defense against aircraft laser threats. The system comprises a viewing device having a frame supporting a transparent viewing surface. The frame is configured to be positioned on the face of a user such that the user may see through the viewing surface. A selective filter is positioned adjacent to the viewing surface such that the angle of the field of view of the user is regulated in at least one orthogonal plane. The viewing angle is selected to prevent light transmitted from a light source, located outside of the viewing angle, from being viewed by the user. The selective filter is configured to operate in a first mode for transmitting light unrestricted through the viewing surface, and a second mode to regulate the angle of the field of view of the user in at least one orthogonal plane.
