Pivotable Mud Ring Support for Flush Electrical Device Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mud rings for electrical devices lack adjustable and secure mounting solutions, making it difficult to position electrical devices flush with walls and ceilings, and they do not provide easy access for installation and maintenance.
Innovation Solution
A mud ring system comprising a base member, a cover, and an insert, where the cover is pivotable and includes a latch for securing the insert to the electrical device, with actuators allowing for adjustment and alignment of the insert relative to the cover, enabling secure and adjustable mounting of electrical devices to junction boxes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a traditional fixed mud ring is used, then the structure is simple, but the electrical device cannot be adjusted to achieve flush mounting with walls and ceilings
Solution Approach 1:
The mud ring incorporates a pivotable cover that can rotate between a closed position (for installation) and an open position (for access), transforming a static structure into a dynamic one. This dynamic feature enables the electrical device to be mounted flush with walls and ceilings while maintaining structural simplicity through the hinge mechanism
Solution Approach 2:
The mud ring is divided into distinct segments: a base member, a pivotable cover, and an insert. This segmentation allows each component to perform its specific function independently—the base provides structural support, the cover provides adjustable access, and the insert secures the electrical device—thereby achieving precise mounting without excessive overall complexity
2Ease of operation
If the cover is made pivotable for easy access, then maintenance access is improved, but the securing reliability may be compromised
Solution Approach 1:
The cover is designed to be dynamically pivotable via a hinge, allowing it to rotate between closed and open positions for easy access during installation and maintenance, while still maintaining structural integrity when closed
Solution Approach 2:
The latch mechanism is pre-configured to automatically engage with the fastener when the cover is in the closed position, securing the cover before any maintenance activity begins. This preliminary securing action ensures reliability is maintained without requiring additional steps
3Reliability
If a latch mechanism is added to secure the cover, then the securing reliability is improved, but the device complexity increases
Solution Approach 1:
The latch is positioned and configured to automatically engage with the fastener when the cover is closed, performing the securing action preliminarily before any maintenance or operation begins. This eliminates the need for separate securing steps while maintaining a relatively simple structure
Solution Approach 2:
The latch mechanism is integrated into the cover structure itself, merging the securing function with the existing cover component rather than adding a completely separate mechanism. This reduces overall device complexity while still providing reliable securing

AI summary
A mud ring supports an electrical device with respect to a junction box. The mud ring includes a base member configured to be coupled to the junction box; a cover coupled to the base member for movement between a first position and a second position, the cover including an opening; and an insert positioned in the opening and supported for movement relative to the cover, the insert configured to be coupled to the electrical device.
