Visual Protection Device Reducing Traumatic Stress via Spectral Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Visual protection devices for task forces, such as firefighters and emergency responders, fail to adequately mitigate the psychological impact of witnessing injured or mutilated individuals, as the vivid imagery of red blood and injuries can lead to long-lasting traumatic stress.
Innovation Solution
A visual protection device with a viewing lens that filters out or absorbs light with wavelengths of 640 nm or more, significantly reducing the perception of red light, thereby minimizing the imprinting of traumatic impressions, while allowing other colors and infrared light to pass through to maintain situational awareness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the viewing lens filters out red light to reduce psychological stress, then the psychological impact of traumatic scenes is reduced, but the ability to recognize hazard symbols and traffic signs may be compromised
Solution Approach 1:
The viewing lens applies different filtering characteristics to different wavelength ranges: it strongly filters red light (640-780nm) to reduce psychological stress, while maintaining transmission of other visible wavelengths and infrared radiation. This localized spectral filtering allows the lens to address the psychological harm specifically without compromising overall visual functionality or hazard detection.
Solution Approach 2:
The patent changes the optical parameters of the viewing lens by specifying precise wavelength ranges for filtering (640-780nm) and transmission (400-640nm). By controlling the spectral transmission characteristics through these parameter specifications, the lens achieves both psychological protection and maintained situational awareness for emergency responders.
2Object-affected harmful factors
If the viewing lens filters out red light to minimize traumatic impressions, then the imprinting of traumatic experiences is reduced, but the perception of blood and injuries becomes less vivid
Solution Approach 1:
The patent converts the harmful effect of red light visibility (which causes vivid traumatic impressions) into a beneficial filtering mechanism. By blocking red wavelengths, the lens reduces the psychological harm of traumatic memories while still allowing emergency responders to perform their duties effectively through maintained visibility of other critical visual information.
3Loss of time
If the viewing lens blocks red light to reduce psychological impact, then stress processing time is reduced, but the ability to perceive infrared radiation may be affected
Solution Approach 1:
The viewing lens segments the electromagnetic spectrum into different functional zones: it blocks the red visible range (640-780nm) to reduce psychological stress, while simultaneously transmitting infrared radiation (780nm and above) to maintain thermal perception capabilities. This spectral segmentation allows independent optimization of psychological protection and infrared detection.
