Solution Overview
Problem
Conventional static illumination systems for vehicles fail to effectively project light beams in changing environments, such as when direction, elevation, or speed shifts, leading to inadequate path illumination.
Innovation Solution
An adaptive illumination system featuring an optical element that moves around an optical axis to redirect light beams in the azimuth plane, combined with a detection system to adjust light direction based on environmental attributes, using a high irradiance white light source and optical components like relay lenses and curved mirrors to collimate and converge light beams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional static illumination system is used, then the system structure is simple, but the illumination coverage is insufficient in dynamic environments
Solution Approach 1:
The patent implements an adaptive illumination system where the optical element can rotate around the optical axis to dynamically adjust the light beam direction in the azimuth plane. This dynamic mechanism allows the headlight to adapt to changing environmental conditions and vehicle steering angles, resolving the contradiction between maintaining simple structure and achieving sufficient illumination coverage in dynamic environments.
Solution Approach 2:
The optical element serves multiple functions: it redirects light beams to adjust illumination direction, works with the detection system to adapt to environmental conditions, and maintains compatibility with the existing headlight structure. This multi-functionality approach enhances illumination coverage without proportionally increasing system complexity.
2Adaptability or versatility
If an adaptive illumination system with moving optical element is implemented, then the illumination adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent combines the detection system and the adaptive optical element into an integrated illumination system. The detection system detects environmental attributes, and this information is used to control the optical element's rotation, creating a unified adaptive system that improves illumination adaptability while managing overall system complexity through functional integration.
Solution Approach 2:
The control system acts as an intermediary between the detection system and the optical element. It processes environmental data and translates it into appropriate optical element positioning commands, enabling adaptive illumination without requiring direct complex mechanical linkages between sensing and actuation components.
3Adaptability or versatility
If the optical element rotates to change light beam direction, then the adaptability to dynamic environments is improved, but the mechanical complexity increases
Solution Approach 1:
The patent replaces complex mechanical linkages with an optical-based redirection mechanism. The optical element rotates on a simplified axis to change light beam direction in the azimuth plane, using optical principles rather than complex mechanical steering mechanisms to achieve the same adaptive illumination effect.
