Reversible Junction Box Cover for Ceiling Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrical devices designed for suspended ceilings often do not fit or install properly in ceilings without sufficient space for utility structures, leading to compatibility issues and limited installation options.
Innovation Solution
The junction box assembly and light emitting panels are designed with a configurable junction box system that allows for flush-mounting in various ceiling types, including non-suspended ceilings, by providing adjustable space and routing channels for electrical conductors, enabling installation in both suspended and non-suspended ceilings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electrical devices are designed for suspended ceilings with sufficient space, then utility structures can be properly housed, but the devices cannot be installed in ceilings without sufficient space
Solution Approach 1:
The junction box is divided into a base portion and a cover portion that can be assembled together. The base portion is installed in the ceiling cavity while the cover portion extends into the finished ceiling space, segmenting the utility housing function from the mounting structure. This allows proper utility housing without requiring excessive ceiling cavity space.
Solution Approach 2:
The junction box design extends utility housing into the third dimension by having the cover portion protrude into the finished ceiling space. This dimensional transition allows the utility structures to be housed in a compact manner within the ceiling cavity while maintaining accessibility and proper spacing in the extended configuration.
2Volume of moving object
If electrical devices are designed with low-profile for non-suspended ceilings, then installation in limited space is enabled, but utility structures have insufficient space
Solution Approach 1:
The cover portion acts as an intermediary element that provides the necessary space for utility structures by extending into the finished ceiling space. This intermediary structure mediates between the limited ceiling cavity space and the required utility housing volume, allowing both constraints to be satisfied.
3Reliability
If electrical devices are designed for suspended ceilings, then proper utility housing is achieved, but the devices are not suitable for non-suspended ceilings
Solution Approach 1:
The junction box assembly is designed with universal adaptability to function in both suspended and non-suspended ceiling applications. The base portion provides universal mounting capability while the cover portion can be configured to accommodate different ceiling types, allowing the same device to serve multiple installation environments with proper utility housing in each case.

AI summary
A junction box assembly may include a junction box base and a junction box cover. The junction box base may define a junction box internal recess. The junction box cover may include a mounting flange, a cover barrier spaced from the mounting flange, and a wall extending between the mounting flange and the cover barrier and defining a junction box cover recess. The junction box cover may be configured to be alternatively coupled to a backing panel to form a junction box, such that either (1) the cover barrier of the junction box cover is received in the junction box internal recess and defines a first junction box space, or (2) the cover barrier is spaced from the backing panel and on a side of the backing panel opposite the junction box base and defines a second junction box space larger than the first junction box space.
