Solution Overview

Problem

Junction boxes often face installation challenges in architectural structures with limited space and small access holes, leading to interference with fixtures and structural obstacles.

Innovation Solution

A bendable and articulable housing for junction boxes that allows the first and second ends to articulate with respect to each other, featuring a hinge mechanism and detents to manage articulation angles, enabling the junction box to navigate through tight spaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional rigid junction box is used, then the structural integrity and electrical connection reliability are ensured, but the junction box cannot be installed in confined spaces with small access holes

Engineering Contradiction:

Improveadaptability to confined spacesVSAvoidstructural rigidity

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The junction box housing is divided into multiple segments that can articulate relative to each other, allowing the housing to bend and conform to confined spaces while maintaining structural integrity through controlled articulation points

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The housing transitions from a static rigid structure to a dynamic articulable structure with hinge mechanisms and detents, enabling the junction box to adapt its shape during installation to navigate through small access holes and elbow-shaped turns

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If the junction box is made articulable to navigate tight spaces, then installation in confined spaces is enabled, but the device complexity increases

Engineering Contradiction:

Improveability to navigate tight spacesVSAvoidhousing mechanism complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The housing is segmented into movable sections connected by hinges, allowing articulation through standardized components rather than complex custom mechanisms, simplifying manufacturing and assembly

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Detent mechanisms are pre-configured in the housing to automatically guide and limit articulation angles during installation, eliminating the need for complex control systems or manual positioning procedures

Inventive Principle:

Principle #10Preliminary action

AI summary

Junction apparatus for providing power to a fixture is provided. The apparatus includes a housing having a first end that is configured to house a line power termination and a second end that is configured to house a load power termination. The first and second ends, or, alternatively, a longitudinal axis of the first end and a longitudinal axis of the second end, or, alternatively, an axis of the first end and an axis of the second end are configured to articulate with respect to each other.
