Gangable Electrical Box Bracket With Threaded Depth Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical boxes often require direct mounting to a single wall stud, limiting flexibility in installation and size adjustment, and lack adjustable mounting brackets for gangable configurations.
Innovation Solution
The electrical box assembly features a mounting bracket with a mounting plate, adjustment plate, and a threaded adjustment member that allows for adjustable positioning relative to a support surface, enabling gangable configurations and depth adjustments between 0.375 and 1.5 inches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mounting brackets are designed to be mounted to a single wall stud, then the mounting structure is simple, but the adaptability and flexibility of installation are limited
Solution Approach 1:
The mounting bracket is designed to perform multiple functions: it can be mounted to wall studs, extend to contact opposing walls, support electrical boxes, and provide adjustable positioning. This multi-functional design allows a single device to replace what would otherwise require multiple different components, thereby improving adaptability without proportionally increasing complexity.
Solution Approach 2:
The mounting bracket incorporates an adjustable mechanism that allows it to dynamically change its configuration during installation. The bracket can be adjusted to accommodate different depths and positions, transforming from a fixed structure to a dynamic one that adapts to various installation scenarios, resolving the contradiction between versatility and complexity.
2Adaptability or versatility
If electrical boxes are required to be mounted directly to wall studs, then the mounting process is straightforward, but the ability to create gangable configurations and adjust depths is limited
Solution Approach 1:
The mounting bracket incorporates a self-adjusting mechanism with threaded rods and locking features that allow the bracket to secure itself to the wall structure without requiring manual holding during assembly. The threaded adjustment members engage with the bracket body and wall anchors to automatically maintain positioning, eliminating the need for assistants to hold components in place during installation.
3Adaptability or versatility
If mounting brackets lack adjustable mechanisms, then the structure is simple, but the depth adjustment range is limited
Solution Approach 1:
The mounting bracket uses threaded adjustment members that allow continuous change of the mounting depth parameter. By rotating the threaded rods, the extension length of the bracket can be precisely adjusted within a range of approximately 0.375 to 1.5 inches, providing fine-tuned depth control while using a relatively simple mechanical threading mechanism rather than complex systems.

AI summary
An electrical box assembly includes a plurality of side walls. At least one of the plurality of side walls has a knockout configured to be removed to receive an electrical conductor. An end wall is releasably connected to the plurality of side walls. The end wall has a groove. A mounting bracket is connected to the end wall. The mounting bracket includes a mounting plate, an adjustment plate, and a threaded adjustment member received in the groove. Rotation of the adjustment member causes the mounting bracket to translate relative to the end wall.
