Solution Overview

Problem

Conventional electrical boxes are limited in design, requiring separate installations for electrical devices on opposite sides of a wall, which can lead to inefficiencies in wiring and increased material usage due to the need for multiple boxes and additional wiring runs.

Innovation Solution

A configurable electrical box with a central divider and cord clamps allows for the securement and connection of electrical devices on both sides of a structural wall within a single box, enabling coaxial placement and daisy-chaining of devices with a single wiring run, while maintaining separate chambers for high and low voltage supplies.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate electrical boxes are installed on both sides of a wall, then each side can have its own electrical device, but the wiring complexity and material usage increase due to multiple boxes and additional wiring runs

Engineering Contradiction:
Improvedual-sided device accessVSAvoidwiring complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines two separate electrical boxes into a single multi-use electrical box with a dividing wall, allowing electrical devices to be installed on both sides of a wall while using one unified structure. This merging eliminates the need for separate boxes and reduces wiring complexity by providing integrated wire access points and cord clamps on both sides of the dividing wall.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If separate electrical boxes are installed on both sides of a wall, then each side can have its own electrical device, but the number of materials and installation steps increase

Engineering Contradiction:
Improvedual-sided device accessVSAvoidnumber of boxes
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent merges two separate electrical boxes into one multi-use box that can accommodate electrical devices on both sides of a wall. The single box structure includes a dividing wall with cord clamps and wire access points on both sides, reducing the quantity of boxes from two to one while maintaining dual-sided functionality.

Inventive Principle:
Principle #5Merging (Combining)

3Quantity of substance

If a single electrical box is used for both sides of a wall, then material usage is reduced, but the box structure becomes more complex

Engineering Contradiction:
Improvenumber of boxesVSAvoidbox structure
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent divides the single electrical box into two separate chambers using a dividing wall, allowing each chamber to house an electrical device independently. The dividing wall includes integrated cord clamps and wire access points on both sides, providing organized wire management while maintaining a relatively simple overall box structure that can be manufactured as a single piece or assembled from simple components.

Inventive Principle:
Principle #1Segmentation
