Lighting Arrangement Tool-Free Mounting Ring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting fixtures require additional holes to be drilled into ceilings or walls for installation, and often necessitate the use of tools for assembly, which can be inconvenient and damaging to the mounting surface.
Innovation Solution
A lighting arrangement that includes a mounting ring with a circular wall and locking arms, allowing direct attachment to a standard junction box without additional holes and tool-free assembly, utilizing a mechanism where posts are rotated and slid along specific surfaces for secure interconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional holes are drilled into ceilings or walls for installation, then secure mounting of lighting fixtures is achieved, but damage to the mounting surface increases and installation complexity increases
Solution Approach 1:
A mounting ring serves as an intermediary component between the lighting fixture and the ceiling/junction box. The mounting ring attaches to the junction box using existing mounting holes, while the lighting fixture attaches to the mounting ring via locking arms and posts, eliminating the need to drill additional holes in the ceiling surface.
Solution Approach 2:
The mounting system is divided into separate functional components: a mounting ring that interfaces with the junction box, locking arms that provide secure attachment, and posts that engage with the lighting fixture housing. This segmentation allows each component to perform its specific function while minimizing damage to the mounting surface.
2Reliability
If tools are used for assembly of lighting fixtures, then secure interconnection of components is achieved, but installation convenience decreases and installation time increases
Solution Approach 1:
The locking arms are designed to automatically engage with the posts through a simple rotational motion, creating a secure interconnection without requiring tools. The spring-loaded mechanism provides automatic locking when the lighting fixture is properly positioned on the mounting ring.
Solution Approach 2:
The locking arms incorporate spring-loaded mechanisms that provide dynamic engagement and disengagement. The springs allow the locking arms to flex during installation and maintain constant contact force, ensuring secure connection while enabling easy release when needed.
3Object-affected harmful factors
If complex mounting mechanisms are used to avoid drilling holes, then damage to mounting surface is minimized, but device complexity increases
Solution Approach 1:
The mounting ring serves multiple functions: it attaches to the junction box using existing holes, provides a mounting surface for the lighting fixture, incorporates locking arms for secure connection, and includes positioning features to guide installation. This multi-functionality reduces the need for additional components while minimizing ceiling damage.

AI summary
A lighting arrangement can include a mounting ring, a luminaire, locking arms, and posts. The mounting ring can extend along a central longitudinal axis. The luminaire can have a housing assembly and a light emitter. The locking arms can each include a circumferential portion extending about the central longitudinal axis. The circumferential portions can each extend from a first end to a second end distal relative to the first end and each can have an upper face and a lower face. The mounting ring and the luminaire can be interconnected by moving the posts past the second ends along the central longitudinal axis, rotating the mounting ring and the luminaire relative to one another about the central longitudinal axis to slide the posts along one of the upper and lower faces.
