Solution Overview

Problem

The installation and alignment of electrical boxes are time-consuming processes due to the lack of flexible and efficient mounting solutions.

Innovation Solution

An electrical installation bracket with telescoping capabilities and rails on its backside allows for adjustable placement and securement of electrical boxes along its length, featuring regularly spaced holes for screw mounting and bendable tabs for stabilization, enabling precise positioning and easy installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional electrical box mounting methods are used, then the mounting process is simple, but the installation and alignment are time-consuming

Engineering Contradiction:
Improveinstallation speedVSAvoidtime for alignment and mounting
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The bracket includes pre-formed rails and regularly spaced holes that are prepared in advance during manufacturing. These features allow the electrical box to be quickly positioned and secured without requiring time-consuming alignment operations during installation, directly reducing installation time while maintaining mounting simplicity

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If fixed-position mounting brackets are used, then the mounting location is precise, but the bracket lacks flexibility for various configurations

Engineering Contradiction:
Improveflexibility in mounting locationsVSAvoidprecision in box placement
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The bracket features multiple discrete mounting holes spaced at regular intervals along the rails, dividing the mounting options into distinct, pre-determined positions. This segmentation allows the electrical box to be precisely positioned at any of these predetermined locations while maintaining manufacturing simplicity, as the holes are formed during bracket manufacturing rather than requiring precise field measurements

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The bracket design allows the electrical box to be positioned dynamically at various locations along the rails by selecting different hole combinations for fastening. This provides adaptability for different configuration needs while maintaining precision through the regularly spaced, pre-manufactured hole pattern that ensures consistent positioning

Inventive Principle:
Principle #15Dynamics

AI summary

An electrical installation bracket includes a body that may telescope to allow the length of the bracket to be changed to accommodate installation in different configurations, for example to accommodate different spacing between mounting studs. The bracket has rails on a face that allow an electrical box to be positioned, by sliding, at any of a variety of locations along the length of the body. The body has holes in it for securing the box to the bracket at a desired location along the body, with a front of the box for example protruding through an opening in the body. The body includes ears on opposite sides of the opening, with mounting holes for mounting the bracket to studs or other structure (or other hardware or devices). The electrical installation bracket advantageously provides more flexibility in placement of electrical boxes, with pre-prepared holes available for securing boxes.
