Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If LED light sources are used for vehicle illumination, then service life and energy efficiency are improved, but the ability to adjust local luminance for self-adaptive lighting is insufficient
Solution Approach 1:
The patent divides the illumination system into multiple independently controllable LED light sources arranged in arrays. Each LED or group of LEDs can be controlled individually to adjust local luminance, enabling self-adaptive lighting patterns while maintaining the overall illumination function.
Solution Approach 2:
The patent implements dynamic control of LED luminance through circuit boards that can independently adjust the brightness of each LED light source. This dynamic adjustment capability allows the system to adapt to different driving conditions and avoid dazzling oncoming vehicles while maintaining adequate illumination.
2Illumination intensity
If high beam illumination is used to ensure desirable illumination, then illumination intensity is improved, but dazzling to oncoming drivers occurs
Solution Approach 1:
The patent applies local quality by allowing different regions of the illumination pattern to have different luminance levels. When an oncoming vehicle is detected, the system reduces luminance in the direction of the oncoming vehicle while maintaining high luminance in other areas, thus avoiding dazzle while preserving illumination effectiveness.
Solution Approach 2:
The patent changes the luminance parameter of individual LED light sources dynamically based on the presence of oncoming vehicles. By adjusting the luminance parameter locally rather than uniformly, the system eliminates dazzle while maintaining overall illumination intensity.
3Adaptability or versatility
If matrix LED self-adaptive headlamp with local luminance control is implemented, then self-adaptive requirement is met, but device complexity increases
Solution Approach 1:
The patent segments the control system into modular circuit boards that interface with arrays of LED light sources. This segmentation allows for scalable implementation where the complexity is distributed across multiple independent control units rather than requiring a single complex control system.

Implementation Method 1
light emitted by the LED light source in the upper row is incident into the lens after being reflected by the upper reflection mirror, and light emitted by the LED light source in the lower row is incident into the lens after being reflected by the lower reflection mirror
