Two-Gang Low Voltage Bracket With Retractable Clamp Arms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional low voltage electrical component mounting devices require extensive time for installation due to the need for locating studs and preparing rectangular holes, which is inefficient and time-consuming.
Innovation Solution
A two-gang low voltage mounting bracket with a frame member and retractable clamp arms that can be easily mounted through a circular aperture, allowing for rapid installation of two components side by side with minimal wall preparation, using a standard hole-saw to create a circular hole and incorporating rotatable clamp arms that fit within the circular profile for easy insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional mounting devices are installed using rectangular holes and stud location, then secure mounting is achieved, but installation time increases significantly
Solution Approach 1:
The mounting device is divided into a front plate and a rearward extending peripheral wall with retractable clamp arms. The clamp arms can be independently positioned to engage with the wall surface, allowing the device to be mounted without requiring stud location or complex wall preparation.
Solution Approach 2:
The clamp arms are designed to be retractable and rotatable between extended and retracted positions. During installation, the clamp arms are extended to engage the wall for secure mounting, and can be retracted when not in use to maintain a compact profile within the circular opening.
2Ease of manufacture
If conventional mounting devices are used, then mounting is achieved, but wall preparation complexity increases
Solution Approach 1:
The mounting device features a substantially round peripheral wall that fits through a circular hole created by a standard hole-saw. This curved geometry simplifies wall preparation compared to rectangular holes, as circular holes can be easily cut with standard hole-saws and do not require precise alignment with wall studs.
3Device complexity
If single-component mounting devices are used, then simple device design is maintained, but productivity decreases
Solution Approach 1:
The mounting device is designed to accommodate two low voltage electrical components side by side within a single front plate. This allows two components to be mounted simultaneously through one circular opening, doubling the installation productivity compared to single-component devices while maintaining a relatively simple overall structure.

AI summary
A two-gang low voltage bracket that enables rapid mounting of one or two low voltage electrical components to a wall. The two-gang bracket includes a front plate with an opening therein and a circular peripheral wall surrounding the opening and extending from the rear surface of the plate. Mounting fasteners extend through oversize holes in the plate and include clamp arms rigidly secured to their ends. The circular peripheral wall is of a diameter that is slightly less than the diameter of a standard size hole-saw. The clamp arms can be rotated to either a retracted or extended position. The peripheral wall is provided with open areas or recesses to fully accommodate the clamp arms when retracted thereby enabling the peripheral wall and clamp arms to pass easily within the wall opening created by the standard size hole-saw.
