Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting arrangements require additional holes in ceilings or walls for installation and often necessitate the use of tools for assembly, which can be inconvenient and time-consuming.
Innovation Solution
A lighting arrangement comprising a mounting ring with a circular wall and locking arms that can be interconnected with a luminaire without the need for additional holes, using a standard junction box, allowing for tool-free assembly by rotating the components relative to each other.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional holes are made in ceilings or walls for installation, then lighting fixtures can be mounted securely, but mounting surfaces are damaged and installation becomes more complex
Solution Approach 1:
The mounting ring is nested within the standard junction box, utilizing the existing opening without requiring additional holes in the ceiling or wall. The mounting ring's circular wall fits inside the junction box while its tabs extend outward to engage with the housing assembly, providing secure mounting while preserving the mounting surface.
2Reliability
If traditional lighting fixtures are installed using tools and multiple holes, then secure mounting is achieved, but installation time increases and convenience decreases
Solution Approach 1:
The mounting ring is divided into functional segments: a circular wall for structural support, tabs for engagement, and locking arms for securing the housing assembly. This segmentation allows each component to perform its specific function independently, enabling tool-free assembly through simple rotational motion while maintaining secure mounting.
Solution Approach 2:
The locking arms are designed to move from an initial position to a locked position through rotational motion. This dynamic mechanism transforms the static mounting process into a simple rotational action, reducing installation complexity and time while ensuring secure engagement between the mounting ring and housing assembly.
3Manufacturing precision
If traditional lighting fixtures require tools for assembly, then precise alignment is achieved, but ease of operation decreases and installation becomes more difficult
Solution Approach 1:
The tabs and locking arms feature asymmetric geometries with specific engagement surfaces and profiles. This asymmetry ensures that the housing assembly can only be installed in the correct orientation, providing precise alignment automatically during the rotational assembly process without requiring tools or complex alignment procedures.
4Adaptability or versatility
If standard junction boxes are utilized without modifications, then adaptability to existing installations is improved, but mounting options become more limited
Solution Approach 1:
The mounting ring serves multiple functions: it provides structural support, enables secure engagement with the housing assembly, facilitates tool-free installation through rotational motion, and ensures precise alignment. This multi-functionality allows the simple mounting ring structure to replace complex traditional mounting systems while maintaining compatibility with standard junction boxes.

AI summary
A lighting arrangement can include a mounting ring and a luminaire. The mounting ring can extend along a central longitudinal axis and have a plurality of tabs, a circular wall, and a plurality of locking arms. Each of the plurality of tabs can define a mounting aperture and the circular wall can interconnect the plurality of tabs. Each of the plurality of locking arms can project from the circular wall and include a circumferential portion extending about the axis. The luminaire can have a housing assembly and a light emitter and a plurality of posts. The mounting ring and the luminaire can be interconnected by moving the posts past distal ends of the locking arms along the axis and then rotating the mounting ring and the luminaire relative to one another in a first angular direction about the axis.
