Solution Overview

Problem

Existing electrical connectors do not efficiently secure two flexible metal conduits or armored cables to a single elongated, solid or rigid tubing/conduit, requiring installers to use connectors not designed for this configuration.

Innovation Solution

A dual or duplex connector with U-shaped clamping brackets and a locking screw mechanism that securely affixes two flexible conduits or cables to one end and allows easy mounting to a single elongated tubing/conduit, enabling rapid and efficient assembly by a single operator.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single flexible metal conduit or armored cable is securely mounted to a junction box or outlet box using prior art connectors, then the mounting is secure and reliable, but there is no capability to mount two flexible metal conduits or armored cables to a single elongated solid or rigid tubing/conduit

Engineering Contradiction:
Improvecapability to mount two flexible conduits to single rigid conduitVSAvoidsecure mounting
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The connector is divided into multiple functional segments: a body portion for receiving the rigid conduit, and multiple clamping brackets (at least two) for independently securing flexible conduits or cables. This segmentation allows the connector to handle multiple flexible conduits simultaneously while maintaining secure mounting for each individual conduit through dedicated clamping mechanisms.

Inventive Principle:
Principle #1Segmentation

2Productivity

If installers use connectors not designed for mounting two flexible conduits to a single rigid conduit, then the installation can be completed, but the process is inefficient and requires multiple connectors

Engineering Contradiction:
Improveinstallation efficiencyVSAvoidnumber of connectors required
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The connector merges multiple mounting functions into a single integrated device. The body portion and multiple clamping brackets work together as one unit to secure both the rigid conduit and multiple flexible conduits simultaneously, eliminating the need for installers to use multiple separate connectors and reducing installation steps.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The connector is designed with multi-functionality to accommodate various conduit types and configurations. The body portion can receive elongated solid or rigid tubing/conduits, while the clamping brackets can secure multiple flexible metal conduits or armored cables, making the single connector applicable to diverse installation scenarios.

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

3Reliability

If traditional mounting methods are used for flexible metal conduits to rigid conduits, then secure mounting is achieved, but the process is time-consuming and requires multiple steps

Engineering Contradiction:
Improvesecure mountingVSAvoidmounting time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The clamping brackets are pre-positioned on the body portion and configured to receive flexible conduits or cables. The locking mechanisms are pre-assembled in the correct positions, allowing installers to quickly secure multiple conduits without requiring complex assembly steps during installation, thereby reducing mounting time while maintaining secure attachment.

Inventive Principle:
Principle #10Preliminary action

AI summary

A dual or duplex conduit/cable connector is constructed for receiving two separate and independent flexible conduits and/or armored or metal clad cables and enabling the two conduit/cables to be securely affixed to one end of the connector. In order to assure efficient assembly of the two flexible metal conduits and/or armored or metal clad cables to the duplex connector, the connector preferably incorporates a clamping bracket associated therewith.
