Automotive Lamp-Camera Assembly With Lens Light Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a camera is mounted to an automobile lamp, light from the lamp's source enters the camera, causing image distortion due to reflection from the lens, leading to a deterioration in image quality.
Innovation Solution
An assembly comprising a light source, camera, and a light blocking member made of a visible light impermeable material that surrounds the camera lens, positioned in close contact with a partition wall or edge, to block light emitted from the light source, and a housing with a hook coupling mechanism for secure integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the camera is mounted to the lamp for an automobile, then the lamp can assist driving by providing both illumination and image capture, but light from the light source enters the camera through reflection from the lens, causing image distortion and deterioration in image quality
Solution Approach 1:
The lamp assembly is segmented into distinct functional zones: a light source unit, a camera unit, and a light blocking member. The light blocking member is positioned between the light source and camera to prevent light from reaching the camera sensor, thereby eliminating image distortion while maintaining both illumination and imaging functions
Solution Approach 2:
A light blocking member is introduced as an intermediary element between the light source and the camera. This mediator component specifically blocks light paths that would otherwise cause reflection and image distortion, allowing both the light source and camera to function simultaneously without interfering with each other
2Manufacturing precision
If the light blocking member is provided to surround the camera lens, then light entering the camera is blocked, but the device complexity increases
Solution Approach 1:
The light blocking member is merged with the housing structure of the lamp assembly. By integrating the light blocking function into the existing housing rather than adding a separate complex component, the design achieves effective light blocking while minimizing increases in device complexity
Solution Approach 2:
The housing structure serves multiple functions: it provides structural support, contains the light source and camera, and incorporates the light blocking member to prevent light from reaching the camera. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents light from entering the camera, thereby maintaining image quality by effectively blocking light from the lamp's source, and provides additional protection against impact and vibration through the use of a synthetic rubber material for the light blocking member.
Implementation Method 1
a light blocking member which is provided to surround an outer side of a camera lens provided in the camera and which is configured to block at least a portion of light emitted from the light source
