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

VSEngineering 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

Engineering Contradiction:
Improveglare from windshield reflectionsVSAvoidadjustability of camera position
Core Design Contradiction:
Object-affected harmful factorsVSAdaptability or versatility

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.

Inventive Principle:
Principle #15Dynamics

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.

Inventive Principle:
Principle #1Segmentation

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

Engineering Contradiction:
Improvereflective interferenceVSAvoidfixed orientation
Core Design Contradiction:
Object-affected harmful factorsVSStability of the object's composition

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.

Inventive Principle:
Principle #15Dynamics

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.

Inventive Principle:
Principle #10Preliminary action

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

Engineering Contradiction:
Improvedistance consistencyVSAvoidrepositioning capability
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

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.

Inventive Principle:
Principle #15Dynamics

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.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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.
