Solution Overview

Problem

Existing electric boxes are not versatile enough to be mounted on various types of wall structures, such as 2×4 lumber studs and ¾ inch furring strips, and face challenges when attached to steel studs, limiting their application in different building constructions.

Innovation Solution

A universally mountable low voltage box bracket with a rectangular open-ended design, featuring laterally extending mounting flanges and slide rails for adjustable positioning, along with an optional detachable conduit support plate, allowing secure attachment to different wall types and orientations, including 2×4 studs, ¾ inch furring strips, and steel studs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If electric boxes are designed for specific wall structures (e.g., 2×4 lumber studs), then they can be securely mounted to that specific structure, but they cannot be applied to other wall structures (e.g., 3⁄4 inch furring strips, steel studs)

Engineering Contradiction:
Improveadaptability to different wall constructionsVSAvoidcomplexity of bracket design
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The bracket is designed with multiple mounting configurations and attachment mechanisms that enable it to be universally applied to different wall structures including 2×4 lumber studs, 3⁄4 inch furring strips, and steel studs. The bracket incorporates adjustable features and multiple mounting orientations that allow a single design to serve multiple wall construction types, eliminating the need for different specialized brackets for each wall type.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If electric boxes are designed to accommodate only specific wall thicknesses, then the mounting structure is simpler, but they cannot be mounted to walls of variable thicknesses

Engineering Contradiction:
Improveadaptability to variable wall thicknessesVSAvoidease of installation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The bracket incorporates dynamic adjustment capabilities that allow it to adapt to variable wall thicknesses. The mounting mechanism includes adjustable components that can be positioned at different depths and angles, enabling the bracket to accommodate walls of varying thicknesses while maintaining secure attachment. This dynamic design allows installers to easily adjust the bracket configuration during installation without requiring complex tools or procedures.

AI summary

A universal electric box bracket adapted for use in walls of various constructions having opposed side walls interconnected by opposed end walls to define a fully open ended rectangular box. The opposed side walls include outwardly extending flanges by which the box bracket may be secured to a stud or furring strip in variable orientated positions. The opposed end walls have connected thereto a pair of spaced apart rails for slidably receiving a support plate for supporting an electrical conduit. The support plate is constructed so that it can be detachably secured when supported between the rails. The respective end walls are also provided with spaced apart fastener supports for holding in place a fastener which can be driven into a supporting stud or framing of a wall structure as an alternate manner of attachment.
