Multi-Camera Assembly Layout for Compact Pan and Tilt
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surveillance cameras face limitations in miniaturization due to the need for spatial leeway to implement panning and tilting movements, resulting in increased product size and restricted spacing between camera assemblies.
Innovation Solution
A multi-camera assembly design featuring frame pans, a frame bottom, shaft pans, and elastic members that allow for smooth panning and tilting while reducing the overall height and size, with a stopper and protrusion mechanism for precise alignment and a compact interface layout.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If spatial leeway is provided for panning and tilting movements, then smooth panning operation is achieved, but product size increases
Solution Approach 1:
The frame pan is rotatably coupled within the housing, and the camera assembly is mounted within the frame pan, creating a nested structure that allows panning movement without increasing the overall product dimensions. The elastic member is nested between the frame pan and frame bottom, providing friction control within the existing structural envelope.
Solution Approach 2:
The elastic member modifies the friction parameter between the frame pan and frame bottom, allowing adjustable resistance during panning operation. By changing the elastic properties or pre-compression of the elastic member, the frictional force can be optimized to provide smooth operation without requiring additional spatial leeway.
2Ease of operation
If spacing between camera assemblies is increased, then panning movement is facilitated, but device complexity increases
Solution Approach 1:
The frame pan serves multiple functions: it supports the camera assembly, provides the panning rotation mechanism, and interfaces with the elastic member for friction control. This multi-functionality eliminates the need for separate structural components that would increase complexity while maintaining panning capability.
Solution Approach 2:
The coupling structure merges the frame pan, frame bottom, and elastic member into an integrated assembly where the elastic member is positioned between the frame pan and frame bottom to simultaneously provide friction control and structural support, reducing the number of separate components and simplifying the overall assembly.
3Volume of moving object
If interface location is optimized, then overall height is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The interface is positioned at the center of the shaft pan, creating a balanced and symmetrical configuration that distributes mechanical loads evenly. This equipotential positioning simplifies the manufacturing requirements by avoiding asymmetric stress concentrations, thereby reducing the actual precision requirements despite the compact height.
