Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video cameras are used to detect vehicles and record evidence, then evidence capture is possible, but 24/7 operation and high quality prosecutable evidence generation are deficient
Solution Approach 1:
The patent replaces traditional mechanical/video-based detection systems with laser-based detection technology. The laser system can operate continuously in all weather conditions and lighting scenarios, enabling 24/7 reliable operation while capturing high-quality evidence through precise laser ranging and imaging capabilities that overcome the limitations of conventional video cameras.
2Reliability
If device-based lockouts and in-vehicle technology are implemented, then distracted driving instances may be reduced, but universal applicability is limited due to opt-in requirements
Solution Approach 1:
The patent introduces an external laser detection system as an intermediary that operates independently of vehicle-based technologies. This external system can detect and record distracted driving behavior without requiring installation inside vehicles or driver consent, thereby achieving universal applicability while maintaining reliable detection capabilities through the laser-based observation and measurement system.
3Measurement precision
If narrow band filtering and flash illumination are used to penetrate windshields, then image quality for detection is improved, but device complexity increases
Solution Approach 1:
The patent employs parameter changes by utilizing specific narrow wavelength bands for laser illumination that can penetrate windshield materials effectively. By selecting and tuning the laser wavelength parameters to match the transmission characteristics of automotive glass, the system achieves high-quality images through the windshield without requiring complex multi-component systems, as the laser parameters themselves are optimized for this specific penetration function.

AI summary
A method for detecting an infringement by vehicle operator is described. The method comprises detecting a vehicle; receiving one or more image of at least a part of the vehicle operator; automatically analysing with a neural network the one or more captured received image to detect an infringing act; and providing the one or more captured received images comprising the detected infringing act to thereby detect the infringement. Also described are a system, a device, a computer system and a computer program product all for detecting an infringement by a vehicle operator. The device may comprise one or more flash for illuminating the vehicle or a part thereof with light at a narrow band and one or more camera comprising a narrow band filter that lets through only the wavelengths of light produced by the one or more flash.
