Ceiling Fan Brace Bracket Assembly for Easier Electrical Box Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of electrical boxes to ceiling fan braces is challenging due to difficulties in aligning screws with threaded holes, especially in dark attic environments, and the presence of protruding screws reduces wiring space and creates abrasive surfaces.
Innovation Solution
A ceiling fan brace bracket assembly with a channel and lip design, featuring press-fit screws and nuts that securely attach the electrical box, reducing abrasive surfaces and facilitating alignment, and a raised ridge for increased rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional brackets with multiple protruding screws are used to attach electrical boxes to ceiling fan braces, then the electrical box can be securely attached, but the number of abrasive surfaces increases and wiring space is reduced
Solution Approach 1:
The bracket is divided into multiple components: a main body with channel, separate lips that fold into position, and integrated screw holes. This segmentation allows the bracket to secure the electrical box effectively while minimizing protruding elements into the box interior, thus reducing abrasive surfaces and wire congestion while maintaining attachment reliability
Solution Approach 2:
The lips are nested within the bracket body during storage and transportation, folding into the channel. During installation, they are folded outward to engage with the electrical box. This nesting approach reduces the number of separate protruding screw components that would otherwise extend into the electrical box, minimizing abrasive surfaces while maintaining secure attachment
2Ease of operation
If the channel opens upward toward the attic, then installation is easier with better visibility, but the design complexity increases
Solution Approach 1:
The lips are integrated as part of the bracket body rather than being separate components, folding into the channel during manufacturing. This merging reduces the number of separate parts and simplifies the overall design while maintaining the upward-opening channel configuration that provides installation advantages from the attic side

AI summary
A ceiling fan brace bracket assembly with a bracket, at least two holes, at least one first screw, and at least one second screw. The bracket has a channel that opens toward a bottom of the bracket and at least one lip that extends along the channel. The channel is sized and shaped to extend around a ceiling fan brace. The at least two holes extend through the at least one lip, and each of the at least two holes is configured to align with a corresponding screw hole in an electrical box. The at least one first screw is a press-fit screw and is configured to extend downward through a first hole of the at least two holes. The at least one second screw is configured to extend upward through a second hole of the at least two holes.
