Twist-Light Mounting System for Lighting Fixtures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Decorative screws used to attach canopy covers to mounting plates in lighting fixtures can damage or strip electrical wires, posing a fire hazard.
Innovation Solution
A twist-lock mounting system that eliminates the need for visible screws by using a canopy cover that is slidably engaged with a mounting plate, secured via a set screw to prevent twisting and dislodging, and features interlocking wings and a track channel for secure attachment without damaging wires.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If decorative screws are used to attach the canopy cover to the mounting plate, then the attachment strength is improved, but the electrical wires can be damaged or stripped creating a fire hazard
Solution Approach 1:
The patent removes the harmful decorative screws from the attachment mechanism between the canopy cover and mounting plate. Instead, it uses a twist-lock mechanism with interlocking features that provide secure attachment without penetrating the canopy cover, thereby eliminating wire damage while maintaining attachment strength
Solution Approach 2:
The patent introduces a twist-lock mechanism as an intermediary between the canopy cover and mounting plate. This mechanism includes interlocking wings and a track channel that engage through rotational movement, providing a secure connection without direct screw penetration into the canopy cover that could damage wires
2Object-affected harmful factors
If a twist-lock mechanism with interlocking wings and track channel is used, then the wire damage risk is eliminated, but the device complexity increases
Solution Approach 1:
The patent combines multiple functions into a single integrated twist-lock mechanism. The interlocking wings, track channel, and set screw work together as one unified system that provides both attachment and anti-rotation functions, reducing the need for separate components and simplifying the overall mounting process
Solution Approach 2:
The patent employs a dynamic twist-lock mechanism where the canopy cover rotates to engage the interlocking wings with the track channel. This rotational engagement provides a simple yet effective locking action that secures the canopy cover without requiring complex fastening procedures

AI summary
A twist-lock mounting system for lighting fixtures includes a mounting plate and a canopy cover. The mounting plate that is secured to a junction box includes a plate body, a first wing, and a second wing. The canopy cover that encloses the electrical wire and electrical connections includes a cover body and a track channel. The first wing and the second wing are laterally connected to the plate body. The first wing is diametrically opposed to the second wing about the plate body. The track channel is perimetrically connected around the cover body. The first wing and the second wing are inserted into the track channel via a pair of access gaps and slidably engaged within the track channel. As a result, the track channel and the cover body are able to enclose the plate body, the first wing, and the second wing.
