Adjustable Camera Holder Ring for Windshield Glare Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera mount systems for vehicle-mounted cameras often suffer from glare issues due to reflections on the windshield, and they may not provide sufficient flexibility in adjusting the camera's orientation and axial position to avoid glare effectively.
Innovation Solution
A camera arrangement comprising a camera head, a camera holder ring, and a camera holder base, where the holder ring is movable along the interaction portion of the camera head until tightened by the receptacle orifice, allowing for axial translation and orientation adjustments to avoid glare.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the camera is mounted on the windshield using a fixed ball-socket mount, then the camera orientation is stable, but glare from windshield reflections interferes with the imaging
Solution Approach 1:
The holder configuration transforms a fixed mounting system into a dynamic, adjustable one. The camera head can be positioned at multiple locations along the holder's length and rotated to different orientations before being locked in place, allowing optimization of the camera's position and angle to avoid glare while maintaining stable mounting.
Solution Approach 2:
The holder is designed as a separate component that divides the camera mounting system into adjustable segments. The camera head can be detached and repositioned at different locations along the holder, enabling independent adjustment of position and orientation to eliminate glare interference.
2Object-affected harmful factors
If the camera head is fixed in a specific orientation, then the field of view is stable, but the camera cannot be repositioned to avoid glare
Solution Approach 1:
The mounting system allows the camera head to be dynamically repositioned and reoriented during installation and maintenance, then locked into a stable fixed position. This provides both the flexibility to avoid glare and the stability needed for consistent field of view during operation.
Solution Approach 2:
The camera head can be preliminarily positioned and oriented during the mounting process to optimize its location and angle for avoiding glare. Once the optimal position is found, the holder is tightened to fixate the camera, preserving both the anti-glare positioning and operational stability.
3Measurement precision
If the distance between the imaging unit and the visual target is kept constant, then measurement accuracy is improved, but the camera cannot be repositioned to optimize field of view
Solution Approach 1:
The holder allows dynamic adjustment of the camera head's position along its length and orientation angle, enabling optimization of both the distance to the target and the field of view coverage. Once optimized, the position is fixed to maintain measurement precision during operation.
Solution Approach 2:
The holder provides additional degrees of freedom by allowing movement along the holder's length (axial dimension) in addition to rotational adjustment. This enables independent optimization of both distance and orientation parameters to achieve both measurement precision and optimal field of view.

AI summary
A camera arrangement comprises a camera head (100), a camera holder ring (108) and a camera holder base (120). The camera head (100) has an imaging unit and an interaction portion (104) with constant cross section. The camera holder ring (108) has an inner surface (110) configured to fit onto the interaction portion (104) of the camera head (100), and the camera holder base (120) has a receptacle orifice (122) dimensioned to receive the camera holder ring (108) fitted onto the interaction portion (104) of the camera head (100) and grip an outer surface of the holder ring (108).The receptacle orifice (122) has a tightening function (124, 126) such that its dimensions may be reduced so as to fixate the camera holder ring (108) and the camera head (100) in relation to the camera holder base (120), and thereby to fixate an orientation of the camera in relation to the camera holder base (120). The camera holder ring (108) is configured to be movable along a length of the interaction portion (104) until the tightening function of the receptacle orifice (122) has been actuated.
