Snap-In Junction Box Bracket for Secure Overhead Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting brackets for electrical boxes lack a secure and modular solution for attaching junction boxes to various support structures, particularly in overhead applications, where they need to be easily secured and adaptable to different types of boxes and structural supports.
Innovation Solution
A snap-in mounting bracket with a body portion and a locking portion, featuring pair of locking arms that extend from the body and are receivable within openings in the junction box, allowing for secure attachment to different support structures and enabling modular compatibility with various junction box types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mounting brackets are used for electrical boxes, then installation is possible, but the attachment is not secure enough for overhead applications and lacks adaptability to different support structures
Solution Approach 1:
The mounting bracket is designed with a universal body portion that can accommodate multiple types of support structures (ceiling joists, metal studs, wooden studs, I-joists) through different attachment features, while the locking portion provides secure overhead attachment. This multi-functional design allows the same bracket to work across various installation scenarios without requiring multiple specialized brackets.
2Ease of operation
If existing mounting methods are used, then electrical boxes can be installed, but the process is time-consuming and lacks a secure locking mechanism
Solution Approach 1:
The locking arms are pre-configured in the locking portion to automatically engage with the body portion upon insertion. This preliminary positioning allows the bracket to be quickly installed by simply inserting the locking portion into the electrical box, with the locking mechanism activating automatically without requiring separate fastening steps or tools.
Solution Approach 2:
The locking mechanism is designed to be self-actuating through spring-loaded locking arms that automatically engage with the body portion when the locking portion is inserted into the electrical box. The spring force provides automatic locking without requiring manual intervention, tools, or additional fasteners, making the installation process both quick and secure.
3Adaptability or versatility
If non-modular mounting brackets are used, then simple manufacturing is possible, but adaptability to different junction box types is limited
Solution Approach 1:
The mounting bracket is divided into two distinct functional segments: a body portion for attaching to support structures and a locking portion for securing to the electrical box. This segmentation allows each part to be optimized independently for its specific function while maintaining overall simplicity in manufacturing through potential integral formation of the two segments.

Function Achieved in This Case
The solution provides a secure, adaptable, and modular attachment system for junction boxes to support structures, ensuring reliable installation in overhead applications and accommodating different types of boxes and supports, with the locking mechanism creating tension for enhanced stability.
Implementation Method 1
The first and second locking arms are moveable relative to each other to engage the second locking arm with the first locking arm to lock the second locking arm to the first locking arm and secure the mounting bracket to the junction box

AI summary
A mounting bracket attaches a junction box to a support structure. The mounting bracket includes a body portion and a locking portion attached to the body portion. The body portion includes at least one attachment feature for attaching the mounting bracket to a support structure. The locking portion includes first and second locking arms that extend from the body portion. At least one of the locking arms is receivable within an opening in the junction box. The first and second locking arms may be moveable relative to each other to engage the locking arms, lock the second locking arm to the first locking arm, and secure the mounting bracket to the junction box when the first locking arm is received in the opening in the junction box.
