Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mud ring assemblies lack adjustability to accommodate varying wall thicknesses and orientations of electrical devices, leading to suboptimal installation and potential exposure of electrical components.
Innovation Solution
A round mud ring assembly comprising a base member, a raised member, a telescoping member, and drive members, allowing for adjustable extension and retraction to fit different wall thicknesses and orientations, ensuring secure installation of electrical devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed mud ring assembly is used, then the structure is simple and easy to manufacture, but it cannot accommodate varying wall thicknesses and orientations
Solution Approach 1:
The mud ring assembly incorporates a telescoping member with drive members that enable dynamic adjustment of the mud ring extension beyond the electrical box. This allows the assembly to adapt to varying wall thicknesses and orientations by moving between retracted and extended positions, transforming a static structure into an adjustable one that maintains adaptability while controlling complexity through mechanical linkage.
Solution Approach 2:
The telescoping member is positioned within the raised member, creating a nested configuration where one component fits inside another. This nesting approach allows the adjustable mechanism to be compact when retracted while still providing extension capability, effectively managing structural complexity by organizing components in a space-efficient hierarchical arrangement.
2Adaptability or versatility
If a fixed mud ring assembly is used, then the manufacturing process is simple, but installation flexibility for different orientations is limited
Solution Approach 1:
The mud ring assembly is divided into distinct functional segments: a base member with flange, a raised member with circular wall, a telescoping member with mounting tabs, and drive members. This segmentation allows each component to be manufactured separately using standard processes, then assembled together to provide installation flexibility for different orientations and wall thicknesses without requiring complex integrated manufacturing.
3Reliability
If the mud ring extends beyond the electrical box, then electrical components are concealed, but the structure becomes more complex
Solution Approach 1:
The telescoping member with drive members serves multiple functions: it extends the mud ring to conceal electrical components, adjusts to varying wall thicknesses, and accommodates different installation orientations. This multi-functionality ensures reliable concealment of electrical components while managing assembly complexity by having a single mechanism perform multiple tasks rather than requiring separate components for each function.

AI summary
A round mud ring assembly includes a base member, a raised member, a telescoping member and a plurality of drive members. The base member has a flange and a circular opening through the flange. The raised member extends from the base member and follows the circular opening in the flange to form a circular raised wall. The raised member has a plurality of mounting tabs extending from the raised wall toward a center of the circular opening. The telescoping member is positioned within the raised member and is movable within the raised member between a retracted position and an extended position. The telescoping member has a circular wall and a plurality of mounting tabs extending from the circular wall toward a center of the circular opening. The circular wall of the telescoping member includes a plurality of protective members. Each protective member is positioned in proximity to one of a mounting tab pairs. In this configuration, one of the plurality of drive members is operatively coupled to the mounting tabs of one of the mounting tab pairs, such that rotation of the drive members causes the telescoping member to move between the retracted position and the extended position.
