Rotating Vehicle Headlight for Curve Illumination Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle headlights fail to provide adequate illumination when navigating curved roads, leading to dark regions that can compromise driver visibility and safety.
Innovation Solution
An adaptive illuminating headlight system featuring a stator and rotor structure with a driver, light emitting unit, and optical assembly that rotates to maintain a consistent illumination pattern, eliminating dark regions by adjusting the light beam based on the vehicle's posture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed orientation illumination pattern is used in conventional headlights, then the structure is simple, but the illumination cannot adapt to vehicle body tilt angle on curved roads, creating dark regions
Solution Approach 1:
The patent implements a dynamic illumination system where the light emitting unit can rotate relative to the headlight housing. The rotor structure with carrying surface allows the light source to change its orientation dynamically, enabling the illumination pattern to adapt to vehicle body tilt angles on curved roads while maintaining a relatively simple overall structure
Solution Approach 2:
The headlight is divided into stationary and rotatable parts. The light emitting unit is separated into a rotor structure that can independently rotate, allowing the illumination function to be decoupled from the fixed headlight housing. This segmentation enables adaptive illumination without requiring the entire headlight assembly to be complex
2Adaptability or versatility
If multiple fill lights are added to provide auxiliary lighting for corners, then the illumination coverage is improved, but the volume of the headlight increases
Solution Approach 1:
Instead of adding multiple static fill lights that would increase headlight volume, the patent uses a single rotatable light emitting unit that can dynamically redirect illumination to corner areas. The rotation capability allows one light source to cover multiple zones including corners, achieving the same illumination coverage benefit without the volume penalty of multiple light sources
Solution Approach 2:
The rotatable light emitting unit serves multiple functions: it provides main beam illumination, corner lighting, and adaptive illumination for curved roads. By making one light source multi-functional through rotation, the system eliminates the need for separate fill lights, maintaining compact headlight volume while achieving comprehensive illumination coverage
