Vehicle Lighting Assembly With Adjustable Beam Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lighting assemblies are unable to adjust the orientation of light rays in horizontal and vertical planes while maintaining a reduced overall dimension, particularly when positioned at the front of a motor vehicle.
Innovation Solution
A vehicle lighting assembly with an optical assembly that includes a movable mirror and/or prism system, allowing adjustable orientation of light rays in horizontal and vertical planes, and a frame that houses the optical components separately from the light source and lens, enabling miniaturization and integration of additional features like Lidar or Radar devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional lighting assembly structures are used, then lighting function is achieved, but the overall dimensions cannot be reduced and light ray orientation cannot be adjusted
Solution Approach 1:
The lighting assembly is divided into separate functional modules: a fixed module containing the light source and lens, and a movable module containing the optical assembly (mirror and/or prism) that can independently adjust light ray orientation. This segmentation allows the lighting function to be maintained while enabling orientation adjustment without proportionally increasing overall dimensions.
Solution Approach 2:
The optical assembly is made movable relative to the light source and lens, allowing dynamic adjustment of light ray orientation in horizontal and vertical planes. The movable module can rotate or pivot to change the direction of reflected or refracted light, providing adaptability while keeping the fixed module compact.
2Adaptability or versatility
If light source and optical components are integrated in the same frame, then structure is simplified, but additional functionalities cannot be integrated
Solution Approach 1:
The assembly is segmented into a fixed module (light source and lens in first frame) and a movable module (optical assembly in second frame). This modular structure allows different functionalities to be integrated in different modules without increasing overall structural complexity, as each module remains relatively simple and self-contained.
Solution Approach 2:
The separated modular structure enables the lighting assembly to perform multiple functions: primary lighting through the light source and lens, light orientation adjustment through the movable optical assembly, and potential integration of additional functionalities (such as sensors or communication devices) in either module without interfering with core lighting operations.
