Solution Overview

Problem

Existing camera base plates require the camera to be detached from accessories for battery replacement, which is inconvenient.

Innovation Solution

A camera base plate with a rotatable wrench connected via a damping assembly, allowing the battery compartment opening to be adjusted without detaching the camera, facilitated by a damping assembly that includes a shaft, connecting members, washers, and elastic members for smooth operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a camera is rigidly mounted to a vehicle, then image stability is improved, but the mounting structure complexity and difficulty of adjustment increase

Engineering Contradiction:
Improveimage stabilityVSAvoidmounting structure complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The mounting system is divided into separate functional components: a base plate with mounting holes for rigid attachment, a camera assembly with adjustable positioning mechanisms, and independent fastening elements. This segmentation allows the base plate to provide stable mounting while the adjustable components enable easy camera positioning without increasing overall structural complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mounting system incorporates adjustable and removable components that transition between fixed and movable states. The base plate provides a stable fixed foundation, while the camera assembly can be dynamically adjusted to different positions and angles, then securely fixed. This dynamic capability allows easy installation, adjustment, and removal without complex permanent structures

Inventive Principle:
Principle #15Dynamics

2Stability of the object's composition

If a camera is rigidly mounted to a vehicle, then image stability is improved, but ease of operation for adjustment and removal increases

Engineering Contradiction:
Improveimage stabilityVSAvoidease of adjustment and removal
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The system separates the stable mounting function (base plate with holes) from the adjustment function (camera assembly with positioning mechanisms). This allows the camera to be easily attached, adjusted, and removed from the stable base plate without compromising image stability during operation

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mounting system enables dynamic adjustment of the camera position and angle during installation, then transitions to a fixed stable state during operation. The adjustable components allow easy manipulation and positioning, while the secure fastening ensures stability once mounted

Inventive Principle:
Principle #15Dynamics

3Stability of the object's composition

If a camera is rigidly mounted to a vehicle, then mounting stability is improved, but adaptability to different mounting locations decreases

Engineering Contradiction:
Improvemounting stabilityVSAvoidadaptability to different mounting locations
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The base plate is designed with multiple mounting holes in various positions and orientations, allowing the same base plate to be universally mounted to different vehicle surfaces (flat or curved) using different hole configurations. This multi-functionality provides adaptability to various mounting locations while maintaining stable attachment through the rigid base plate structure

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The present disclosure discloses a camera base plate, which includes a plate body and a wrench. The plate body is defined with a battery avoiding port corresponding to an opening of a battery compartment of a camera. The battery avoiding port extends along a thickness direction of the plate body. The wrench is rotatably connected to the plate body through a damping assembly, and the wrench defines a part of a side wall of the battery avoiding port. In the present disclosure, the wrench can rotate to be gradually opened so as to define a gap in the battery avoiding port. After the plate at the opening of the battery compartment of the camera is fully opened, a portion of the plate extends into the gap, thereby the plate can be opened completely, such that the battery can be removed or placed without detaching the camera from the camera base plate.
