Solution Overview

Problem

Existing electrical box mounting systems, especially when installed at high positions, require complex and hazardous procedures involving tools and intermediate components, increasing difficulty and risk during installation.

Innovation Solution

An electrical box with a mounting assembly comprising clips and tabs that securely engage a mounting bracket without tools, allowing for easy rotation and secure attachment, and a hanger clip system with a lever for horizontal adjustment, facilitating safe and simple installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Weight of moving object

If electrical boxes are mounted at high positions using traditional methods, then the electrical box can be installed in elevated locations, but the installation process becomes complex and hazardous requiring tools and intermediate components

Engineering Contradiction:
Improveinstallation complexityVSAvoidinstallation hazards
Core Design Contradiction:
Weight of moving objectVSObject-affected harmful factors

Solution Approach 1:

The mounting assembly is integrated directly into the electrical box structure, merging the box and mounting components into a single unit. This eliminates the need for separate intermediate mounting components and tools, allowing installers to simply hang the box on the bracket without complex assembly procedures or additional tools.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The electrical box is designed with self-contained mounting features (clips and tabs) that automatically engage with the mounting bracket. The tabs fold over the bracket flanges and the clips secure the box to the bracket through simple manual manipulation, making the installation process self-serviceable without requiring external tools or intermediate components.

Inventive Principle:
Principle #25Self-service

2Reliability

If traditional mounting components are used, then the electrical box can be secured to the bracket, but additional intermediate components increase assembly complexity

Engineering Contradiction:
Improvemounting securityVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The mounting assembly is integrated directly into the electrical box structure, merging the box and mounting components into a single unit. This eliminates the need for separate intermediate mounting components and tools, allowing installers to simply hang the box on the bracket without complex assembly procedures or additional tools.

Inventive Principle:

3Strength

If tools and intermediate components are required for mounting, then secure attachment can be achieved, but the installation process becomes more difficult and time-consuming

Engineering Contradiction:
Improveattachment strengthVSAvoidinstallation ease
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The electrical box is designed with self-contained mounting features (clips and tabs) that automatically engage with the mounting bracket. The tabs fold over the bracket flanges and the clips secure the box to the bracket through simple manual manipulation, making the installation process self-serviceable without requiring external tools or intermediate components.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The mounting assembly incorporates movable tabs that can be folded from a first position to a second position to transition between open and closed channel configurations. This dynamic feature allows the installer to easily open and close the mounting channels during installation without requiring tools, while still providing secure attachment when closed.

Inventive Principle:
Principle #15Dynamics

AI summary

A bracket mountable electrical box having a mounting assembly or device that can secure the electrical box to a mounting bracket. The mounting assembly or device can include one more arms that can define at least a portion of a channel that can receive the mounting bracket. The channel can be selectively closed, or at least partially deformable, in a manner that can assist in retaining the engagement between the mounting bracket and the mounting assembly or device, and thus the electrical box. Such configurations can accommodate securing the electrical box to the mounting bracket without at least the use of additional tools.
