Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a conventional visible-light high beam system is used to illuminate the road for vision systems during night driving, then the illumination range is sufficient, but it causes glare to preceding or oncoming vehicles
Solution Approach 1:
The patent changes the wavelength parameter of the light source from visible light to infrared light. The infrared matrix lamp emits infrared light that illuminates the road and targets for vision systems without causing glare to human drivers, as infrared light is invisible to the human eye. This parameter change resolves the contradiction by maintaining illumination effectiveness while eliminating the harmful glare effect.
2Area of stationary object
If all infrared light sources in the infrared matrix lamp are turned on to provide comprehensive illumination, then the illumination coverage is maximized, but the energy consumption increases
Solution Approach 1:
The patent divides the illumination system into multiple independently controllable infrared light sources arranged in a matrix pattern. Instead of illuminating the entire road uniformly, the system segments the illumination task and activates only specific light sources corresponding to detected targets or regions of interest. This segmentation allows the system to maintain comprehensive illumination coverage when needed while reducing energy consumption by activating only necessary light sources in other scenarios.
Solution Approach 2:
The infrared matrix lamp controller dynamically adjusts which infrared light sources are activated based on real-time detection data from radar and vision systems. The system transitions between different illumination states (full illumination, partial illumination, or no illumination) depending on the driving situation, target distance, and environmental conditions. This dynamic control optimizes the balance between illumination coverage and energy consumption.
3Measurement precision
If the infrared matrix lamp controller activates infrared light sources based on precise relative position information, then the illumination precision is improved, but the device complexity increases
Solution Approach 1:
The infrared matrix lamp controller is designed to perform multiple functions: it receives and processes position information from radar systems, processes target detection data from vision systems, calculates the appropriate illumination pattern, and controls the activation of individual infrared light sources. By making the controller multi-functional and integrating these capabilities into a single device, the system achieves precise illumination control without proportionally increasing overall device complexity.
