Electrical Box Cover with Dual-Orientation Mounting Ears
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical boxes are often recessed within walls due to improper positioning during construction or renovation, making electrical devices inaccessible and requiring tedious and costly replacement of entire junction boxes to accommodate new fixtures.
Innovation Solution
The use of adapter covers with adjustable side walls and mounting ears that can be secured to existing junction boxes, allowing for easy installation of new devices by bridging the gap between different shaped junction boxes and fixtures, and optionally using masonry brackets for secure installation in masonry structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electrical boxes are mounted recessed within walls during construction or renovation, then the wall structure can be properly finished, but the electrical devices become inaccessible and require costly replacement of entire junction boxes
Solution Approach 1:
The cover plate assembly serves as an intermediary component between the recessed electrical box and the electrical device. It bridges the gap by providing a mounting surface that extends the electrical box to the wall surface, allowing devices to be mounted without replacing the entire junction box structure.
Solution Approach 2:
The solution segments the electrical mounting system into separate functional components: the existing electrical box (for wiring), the cover plate assembly (for device mounting), and the electrical device itself. This allows independent replacement or adjustment of the cover plate without disturbing the wired box.
2Adaptability or versatility
If multiple electrical devices with different shapes are to be accommodated, then versatility is improved, but the cover plate design becomes more complex
Solution Approach 1:
The cover plate is designed with universal features including multiple sets of mounting ears positioned at different locations and orientations, allowing a single cover plate design to accommodate various electrical devices such as outlets, switches, and thermostats with different mounting requirements.
Solution Approach 2:
The cover plate incorporates adjustable elements including side walls that can be positioned at different heights and mounting ears that can be selectively used based on the specific device requirements, providing adaptability without requiring multiple specialized cover plate designs.

AI summary
A cover plate for an electrical box includes a base plate and a plurality of side walls extending from the base plate. The plurality of side walls at least partially define a central opening. The plurality of side walls including a curvilinear wall and a set of opposing rectilinear walls. A first set of mounting ears extends from the plurality of side walls into the central opening. The first set of mounting ears are positioned to receive an electrical device in a first orientation. A second set of mounting ears extend from the plurality of side walls into the central opening. The second set of mounting ears are positioned to receive an electrical device in a second orientation.
