Concealed Junction Box Cover for Convertible Lighting Fixtures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recessed lighting fixtures are not easily convertible to different types, such as hanging or spotlight fixtures, and conversion solutions often detract from the aesthetic appeal by being visible.
Innovation Solution
A junction box cover assembly comprising a cover plate, hub, and circular insert that allows for easy attachment and concealment of electrical wiring, enabling multiple lighting options while maintaining a flush and aesthetically pleasing installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If recessed lighting fixtures are installed in walls or ceilings, then lighting functionality is provided, but the fixtures cannot be easily converted to different types and conversion solutions are visible and detract from aesthetic appeal
Solution Approach 1:
The invention divides the lighting system into separate modular components: a junction box cover that remains permanently installed and aesthetic, and detachable adapter assemblies that enable different lighting fixture types. This segmentation allows easy conversion between lighting types by simply removing and replacing the adapter, without affecting the permanent installation or visual appearance of the wall or ceiling.
Solution Approach 2:
The invention introduces an intermediary adapter assembly that connects between the fixed junction box cover and various lighting fixture types. This adapter serves as a mediator that enables conversion functionality while remaining hidden behind the aesthetic cover, thus providing adaptability without visible complexity or aesthetic compromise.
2Adaptability or versatility
If conversion connectors and adapters are used to change lighting fixture types, then lighting versatility is achieved, but the connectors and adapters are visible and detract from aesthetic appeal
Solution Approach 1:
The invention implements a nested structure where the adapter assembly and lighting fixture are contained within or behind the aesthetic junction box cover. The adapter is positioned such that only the necessary functional portions extend through the cover, while the conversion mechanisms remain hidden, achieving versatility without compromising aesthetic simplicity.
Solution Approach 2:
The invention applies different qualities to different parts of the system: the junction box cover maintains a clean, aesthetic appearance suitable for visible surfaces, while the adapter assemblies provide the necessary mechanical conversion functionality in hidden or functional zones. This local differentiation allows aesthetic simplicity to be preserved while enabling fixture conversion.
3Illumination intensity
If recessed can-light fixtures are installed, then broad area lighting is provided, but conversion to hanging or spotlight fixtures is difficult and requires visible adapters
Solution Approach 1:
The invention creates a dynamic system where the lighting fixture type can be changed by simply detaching and reattaching adapter assemblies, rather than requiring complex conversion procedures. The adapter designs enable quick installation and removal, allowing the lighting system to adapt dynamically to different functional needs without difficult operations or visible hardware.

AI summary
A junction box cover assembly for attachment over an opening in an electrical junction box allows for a concealed connection to avoid detracting from the lighting fixture. The assembly includes a cover plate capable of being mounted to a junction box, the cover plate having an opening there through defined by a first threaded collar extending from the cover plate, a hub having a flange radially extending from a periphery of a second threaded collar defining a passage and configured to attach to the first threaded collar of the cover plate, and a circular insert detachably connected within the passage defined by the threaded collar, the circular insert having an opening for passing electrical wiring from the junction box through the passage, out the insert opening and to a light fixture. The cover plate and the radially extending flange somewhat sandwich a surface, such as drywall or wallboard, and the flange is configured to permit covering with spackling paste or joint compound to conceal the flange.
