Rotatable Housing for High Voltage Device Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High voltage electrical equipment is cumbersome and heavy, making it difficult to align properly during installation on utility structures, often requiring heavy equipment for manipulation.
Innovation Solution
A rotatable cylindrical lower housing with a surrounding mounting bracket and anti-rotation fastener system allows for easy alignment and secure mounting on utility poles, enabling the housing to rotate freely while preventing unintended movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If high voltage electrical equipment is mounted onto utility structures, then the equipment can be installed and operated, but the equipment is cumbersome and heavy making it difficult to align properly during installation
Solution Approach 1:
The mounting bracket incorporates a rotatable housing that can freely rotate during installation to enable proper alignment with connecting equipment. The rotation capability allows installers to easily orient the heavy electrical device without requiring heavy lifting equipment, and after alignment is achieved, the housing can be secured in position.
2Ease of operation
If the housing is made rotatable to facilitate alignment, then ease of installation is improved, but the housing may unintendedly move or become unstable
Solution Approach 1:
The mounting bracket includes a fastening mechanism that can prevent rotation of the housing once proper alignment has been achieved. This preliminary anti-action ensures that the housing remains stable and secure during operation while still allowing rotation during the installation phase for alignment purposes.

AI summary
A rotatable lower housing (10) for a high voltage electrical circuit or other high voltage electrical device is provided that allows a cylindrically-shaped lower housing (10) to be rotatable with respect to a bracket (12) for mounting the lower housing onto a support structure (13). Embodiments that allow for the rotatable lower housing include a one-piece surrounding mounting bracket (12), an upper and lower band which completely surround the lower housing and which are attached to a bracket, and an integral surrounding I-slot which surrounds the lower housing and which receives a bracket for mounting the lower housing onto a support structure.
