Solution Overview

Problem

Conventional surveillance cameras face challenges in securing sufficient spacing between camera modules for panning, leading to increased product size and limitations in miniaturization.

Innovation Solution

A multi-camera assembly is designed with a plurality of camera modules, frame pans, a frame bottom, a shaft pan, and elastic members to facilitate smooth panning, reduce module size, and improve interface locations for a compact structure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If spacing between camera modules is increased to enable smooth panning, then panning performance is improved, but product size increases

Engineering Contradiction:
Improvepanning smoothnessVSAvoidproduct size
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

The patent introduces an elastic member that enables dynamic adjustment of spacing between camera modules. The elastic member allows the modules to move closer during panning operation while maintaining smooth rotational movement, and returns to original position when panning is completed. This dynamic mechanism resolves the contradiction by providing panning smoothness without requiring permanently increased product size.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the spacing parameter between camera modules from a fixed value to a variable value that adjusts during panning operation. The elastic member enables the spacing to change dynamically - decreasing during panning for smooth operation and increasing when idle to minimize overall product size. This parameter change approach allows the system to optimize both panning performance and compactness at different operational states.

Inventive Principle:
Principle #35Parameter changes

2Volume of moving object

If camera module size is reduced to secure panning spacing, then product compactness is improved, but panning angle is limited

Engineering Contradiction:
Improvecamera module sizeVSAvoidpanning angle
Core Design Contradiction:
Volume of moving objectVSAdaptability or versatility

Solution Approach 1:

The elastic member enables dynamic spacing adjustment that allows smaller camera modules to achieve larger effective panning angles. As modules rotate, the elastic member compresses and extends, permitting greater angular displacement than would be possible with fixed rigid mounting. This dynamic mechanism allows reduced module size while maintaining or even increasing the achievable panning angle range.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent segments the rigid connection between frame pan and camera modules by introducing the elastic member as a flexible connection element. This segmentation allows each camera module to be smaller while the elastic connection compensates for the reduced individual module capabilities through flexible movement, thereby maintaining the overall panning angle requirement.

Inventive Principle:
Principle #1Segmentation

3Volume of moving object

If interface location is improved to reduce overall height, then product compactness is enhanced, but structural complexity increases

Engineering Contradiction:
Improveoverall heightVSAvoidinterface location
Core Design Contradiction:
Volume of moving objectVSDevice complexity

Solution Approach 1:

The patent relocates the interface from a side-positioned configuration to a top-positioned configuration on the frame pan. This dimensional change in interface location allows the overall height of the product to be reduced, as the interface now utilizes the vertical space above the camera modules rather than extending the side profile. The structural complexity increase is minimal, involving primarily the repositioning of interface components to the top surface of the frame pan.

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