Engineering Contradiction Analysis
1Adaptability or versatility
If a predefined light distribution is generated using multiple optical units assigned to different light sources, then different partial light distributions with light spots of different sizes can be formed, but the system complexity increases and energy optimization based on environmental conditions is insufficient
Solution Approach 1:
The patent segments the light distribution control into multiple independent optical units, each assigned to different light sources. Each optical unit can generate different partial light distributions with light spots of different sizes, which are then superimposed to form the complete light distribution. This segmentation allows independent control of each optical unit based on environmental parameters, enabling optimized light distribution without requiring complete system reconfiguration.
Solution Approach 2:
The control unit dynamically adjusts the light distribution by continuously monitoring environmental parameters (such as oncoming vehicles, light poles, road conditions) and generating corrected control signals in real-time. The system transitions from a static predefined light distribution to a dynamic optimized distribution that adapts to changing environmental conditions, improving adaptability while maintaining manageable system complexity through modular optical units.
2Use of energy by moving object
If the headlight emits maximum light to ensure visibility in all conditions, then lighting quality is maintained, but energy consumption increases unnecessarily in conditions requiring less light
Solution Approach 1:
The control unit changes the operational parameters of the light sources and optical units based on detected environmental conditions. When environmental parameters indicate sufficient ambient light or specific conditions (such as presence of oncoming vehicles, light poles, or specific road conditions), the control unit generates corrected control signals that reduce the intensity or adjust the distribution of light emitted. This parameter adjustment allows energy consumption to be optimized while maintaining adequate lighting quality for safe driving.
Solution Approach 2:
The system implements a feedback mechanism where the control unit continuously monitors environmental parameters and uses this information to generate corrected control signals that adjust the light distribution. The feedback loop ensures that light emission is optimized based on actual environmental conditions rather than operating at maximum capacity continuously, thereby reducing energy consumption while maintaining lighting quality where and when it is needed.
