Rotating Camera Mount Assembly for Single-Person Overhead Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of surveillance cameras and other electronic devices on high or inaccessible mount surfaces is ergonomically challenging and inefficient, often requiring two people due to varying loads and potential misalignment during installation, especially in reverse directions.
Innovation Solution
A camera mount assembly with a base and mount that rotate relative to each other via a cam bolt and guide frame, allowing single-person installation and electrical connection, featuring a cam profile and bias spring for easy assembly and alignment, with integrated circuit boards and connectors for electrical and waterproof sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the installation unit is mounted below the base unit in reverse direction, then the camera can be installed on high or inaccessible mount surfaces, but the load felt by the installation person increases making it difficult to install with one person
Solution Approach 1:
The base unit is designed to rotate about a common axis between forward and reverse installation directions, transforming a static mounting structure into a dynamic one. This rotation allows the installation direction to be changed adaptively, enabling the system to work in both forward and reverse directions while maintaining manageable load characteristics through proper orientation selection
Solution Approach 2:
The mounting system is divided into separable components: the base unit fixed to the support surface and the installation unit holding the camera. These segments can be assembled and disassembled independently, allowing flexible configuration for different installation scenarios including high or inaccessible mount surfaces
2Ease of operation
If the installation person holds the base unit and assembles the installation unit, then the camera can be installed, but the panning part of the camera may turn causing installation difficulty
Solution Approach 1:
A guide frame with cam profile acts as an intermediary mechanism between the cam bolt and the mounting interface. This guide frame controls the relative movement and rotation during assembly, ensuring that the installation unit aligns precisely with the base unit while preventing unwanted panning part rotation through the constrained cam mechanism
Solution Approach 2:
The cam bolt and guide frame mechanism enables the installation unit to self-align with the base unit during rotation. As the installation person rotates the installation unit, the cam profile automatically guides the alignment process, eliminating the need for manual adjustment and ensuring precise alignment without requiring the installation person to hold and adjust multiple components simultaneously
3Ease of manufacture
If the mount rotates with respect to the base, then assembly is simplified, but the gap between base and mount varies requiring precise control
Solution Approach 1:
The cam profile is pre-designed with specific geometric characteristics that automatically control the gap variation during rotation. The cam profile shape is calculated in advance to ensure that as the cam bolt follows the cam profile during mount rotation, the gap between base and mount varies in a controlled manner that achieves proper alignment and assembly at the final position
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables single-person installation and simultaneous electrical connection and waterproofing of cameras, reducing installation difficulty and ensuring ergonomic efficiency.
Implementation Method 1
a cam bolt fixed to the other from among the mount and the base, wherein, based on the mount rotating with respect to the base, one side of the cam bolt is configured to move along the cam profile formed in the guide frame such that a size of a gap between the base and the mount varies
Implementation Method 2
a bias spring configured to provide a biasing force to the base and the guide frame such that, when the mount rotates with respect to the base during at least one portion of rotation of the mount, the gap between the mount and the base is maintained due to the biasing force
