Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for protecting eyes against radiation, such as laser and infrared attacks, are insufficient in blocking small beam diameters and do not meet the required standards for light transmittance, particularly in aviation and transportation, leading to potential eye damage and distraction.
Innovation Solution
A device with dual sensor arrangements and a fast, electronically or mechanically controlled closing mechanism that interrupts radiation by detecting its approach and closing the radiation passage opening within milliseconds, ensuring minimal disruption to the wearer's vision and compliance with ISO standards for light transmittance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a closing device is used to block radiation, then eye protection against radiation is improved, but light transmittance and clear vision are reduced
Solution Approach 1:
The external sensor arrangement detects incoming radiation before it reaches the eye and triggers the closing device to close in advance, blocking the radiation before it can cause damage. This preliminary detection and action allows the system to protect the eye while maintaining clear vision during normal conditions when no radiation is present.
Solution Approach 2:
The closing device transitions dynamically between open and closed states based on real-time radiation detection. During normal operation, the device remains open to allow clear vision and light transmittance. When radiation is detected by the sensor arrangements, the device rapidly closes to block the radiation, then reopens after the threat passes, optimizing both protection and vision clarity.
2Object-affected harmful factors
If the closing device remains closed to block radiation, then radiation protection is improved, but vision disruption and distraction increase
Solution Approach 1:
The closing device operates periodically rather than continuously - it closes only during the brief period when radiation is detected and reopens immediately after the radiation threat passes. This periodic operation minimizes vision disruption time while maintaining effective radiation protection, allowing the wearer to have clear vision most of the time.
Solution Approach 2:
The system replaces slow mechanical eyelid closure with an electronically controlled closing device that can open and close rapidly in response to radiation detection. This substitution enables the device to close for only the necessary duration to block radiation, significantly reducing vision disruption time compared to manual blinking or sustained closure.
3Device complexity
If a single sensor arrangement is used, then device complexity is reduced, but detection precision and reliability of radiation detection are insufficient
Solution Approach 1:
The sensor system is segmented into two distinct arrangements: an external sensor arrangement positioned away from the eye and an internal sensor arrangement positioned closer to the eye. This segmentation allows each sensor to perform a specific detection function - the external sensor detects incoming radiation first, providing early warning, while the internal sensor confirms radiation presence near the eye, together providing precise and reliable detection with reduced false alarms.
Solution Approach 2:
The external sensor arrangement acts as an intermediary between the incoming radiation and the internal sensor arrangement. It detects radiation first and provides early warning, allowing the system to prepare for closure. This intermediary detection layer improves overall detection precision by providing a two-stage verification process before triggering the closing device.

Function Achieved in This Case
Effectively blocks small beam diameters and high-intensity radiation, maintaining clear vision and adhering to safety standards by rapidly closing and reopening the radiation passage, thus providing enhanced protection against laser and infrared attacks while ensuring good color recognition and compliance with aviation and transportation standards.
Implementation Method 1
each sensor arrangement comprises a plurality of radiation sensors arranged one after the other, which are each arranged along a closed curve
Implementation Method 2
a closing device is arranged in such a way with respect to the radiation passage region, that an incident radiation passing through the radiation passage opening is either let pass through or completely closed or at least partially attenuated by a tinted surface
