Adjustable Camera Holder Ring for Windshield Glare Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera holder configurations for vehicles suffer from glare interference due to reflections on windshields and lack of flexibility in orientation and axial positioning, which prior solutions have not adequately addressed.
Innovation Solution
A camera arrangement with a camera head, holder ring, and holder base that allows for adjustable orientation and axial translation, using a movable holder ring with a tightening mechanism to secure the camera's position, and optional guiding features for precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a ball-socket mount with vacuum clamp is used to mount the camera on the windshield, then the camera can be securely fixed, but the camera cannot be adjusted for orientation and axial position
Solution Approach 1:
The holder ring is designed to be movable along the interaction portion of the camera head before tightening, enabling dynamic adjustment of the camera's axial position and orientation. After adjustment, the receptacle orifice is tightened to fixate the camera in the desired position, transforming the system from static to dynamically adjustable.
Solution Approach 2:
The mounting mechanism is divided into separate functional components: a movable holder ring for positioning, a receptacle orifice for tightening, and an interaction portion for engagement. This segmentation allows independent adjustment of position and orientation before final fixation.
2Object-affected harmful factors
If the camera is mounted close to the windshield to reduce glare, then the field of view is improved, but the camera may still experience reflection interference
Solution Approach 1:
The movable holder ring enables the camera to be positioned at different axial distances from the windshield surface. This dynamic positioning capability allows optimization of the camera's location to minimize glare and reflection interference while maintaining a clear field of view.
Solution Approach 2:
The axial position parameter of the camera relative to the windshield can be varied by moving the holder ring along the interaction portion. This parameter change allows finding the optimal mounting distance that reduces harmful reflections while preserving imaging quality.
3Adaptability or versatility
If a spherical joint with collar and cup is used to couple the camera accessory, then the camera can be mounted on various surfaces, but the positioning precision and stability are insufficient
Solution Approach 1:
The holder ring provides initial adjustability for positioning the camera with precision on various surfaces. The subsequent tightening of the receptacle orifice locks the position, combining the benefits of adaptability with high positioning precision and stability.
Solution Approach 2:
The camera position and orientation are adjusted preliminarily by moving the holder ring before tightening. This preliminary positioning action ensures precise alignment and stable mounting on various surfaces before the final fixation is applied.

AI summary
A camera arrangement comprises a camera head, a holder ring and a holder base. The camera head has an imaging unit and an interaction portion with constant cross section. The camera holder ring has an inner surface configured to fit onto the interaction portion of the camera head, and the camera holder base has a receptacle orifice dimensioned to receive the camera holder ring fitted onto the interaction portion of the camera head and grip an outer surface of the holder ring. The receptacle orifice has reduced dimensions due to a tightening function to fixate the camera holder ring and the camera head in relation to the camera holder base, and thereby to fixate an orientation of the camera in relation to the camera holder base. The camera holder ring is movable along a length of the interaction portion until the tightening function of the receptacle orifice has been actuated.
