Adaptive Headlight Rotor Assembly for Curve Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional vehicle headlights lack the ability to adjust their illumination patterns to adapt to a vehicle's tilt angle, leading to dark regions when driving on curved roads, which can impair visibility and increase the risk of accidents.
Innovation Solution
An adaptive illuminating headlight system that includes a stator structure, a rotor structure, a driver, a light emitting unit, and a control unit, where the rotor structure rotates relative to the stator structure to adjust the illumination pattern based on the vehicle's posture, ensuring consistent frontal illumination without the need for auxiliary lights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed orientation illumination pattern is used in traditional headlights, then the structure is simple, but the illumination cannot adapt to vehicle tilt angle changes, causing dark regions on curved roads
Solution Approach 1:
The patent implements a rotatable illumination assembly that can dynamically adjust its orientation angle relative to the vehicle body. The rotation mechanism allows the illumination pattern to tilt in response to vehicle posture changes, transforming a static fixed-orientation system into a dynamic adaptive system that maintains proper light distribution on curved roads
Solution Approach 2:
The patent integrates the driver and control unit into the rotor structure, creating a nested configuration where control components are housed within the rotating assembly. This nesting approach reduces overall device complexity by consolidating multiple components into a compact integrated unit while maintaining adaptability functionality
2Adaptability or versatility
If fill lights are arranged to provide auxiliary lighting for corners, then illumination adaptability is improved, but the volume of the headlight cannot be reduced
Solution Approach 1:
Instead of using additional static fill lights, the patent employs a single rotatable illumination assembly that dynamically adjusts its orientation to provide corner lighting when needed. This dynamic approach eliminates the need for multiple auxiliary light sources, reducing headlight volume while maintaining corner lighting capability through angular adjustment
Solution Approach 2:
The rotatable illumination assembly serves multiple functions: it provides main forward illumination and simultaneously acts as a fill light for corners by adjusting its orientation. This multi-functional design eliminates the need for separate dedicated corner lighting components, reducing overall headlight volume while maintaining adaptability
