Engineering Contradiction Analysis
1Speed
If linear brightness control is used to adjust illumination based on environmental changes, then the system responds quickly to environmental changes, but the brightness changes abruptly causing driver distraction and visual fatigue
Solution Approach 1:
The patent applies parameter changes by transitioning from linear to nonlinear brightness control functions. The controller adjusts the brightness parameter of light sources using a nonlinear function that maps environmental brightness changes to illumination adjustments, ensuring smooth transitions that prevent driver distraction while maintaining responsive adaptation to environmental conditions.
2Manufacturing precision
If high resolution light source control is implemented to accurately control light beams, then illumination precision is improved, but the system complexity increases
Solution Approach 1:
The patent applies universality by implementing a unified nonlinear dimming function that serves multiple purposes: it controls brightness transitions smoothly, adapts to various environmental conditions, and works across different light source types. This single nonlinear control mechanism replaces the need for complex individual control systems for each light source, reducing overall system complexity while maintaining high precision light beam control.
