Solution Overview

Problem

Existing electrical conduit fittings lack effective mechanisms for securely and removably retaining electrical conduits during installation, particularly in press connections, which can lead to misalignment and improper connection.

Innovation Solution

The introduction of a conduit retainer within the electrical conduit fitting that releasably grips and removably retains the conduit, providing axial alignment and secure positioning before press connection, using deformable barbs and resilient detents to ensure proper engagement and sealing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional conduit fittings without retainers are used, then the device complexity is reduced, but the reliability of conduit retention and alignment deteriorates

Engineering Contradiction:

Improveconduit retention and alignmentVSAvoidfitting structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The conduit retainer is installed in the fitting before the conduit is inserted, establishing a preliminary gripping mechanism that automatically engages with the conduit to prevent misalignment and ensure proper positioning during the connection process

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The conduit retainer acts as an intermediary component between the fitting and the conduit, providing a mechanical interface that grips the conduit and transmits alignment forces, thereby improving retention reliability without requiring complex integration of the fitting itself

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If a conduit retainer with deformable barbs and resilient detents is added, then the ease of operation for secure retention is improved, but the device complexity increases

Engineering Contradiction:

Improveconduit insertion and retentionVSAvoidretainer mechanism

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The retainer incorporates deformable barbs and resilient detents that dynamically adjust during conduit insertion, allowing the components to flex and conform to the conduit surface for secure gripping, then maintain constant retention pressure without requiring complex adjustment mechanisms

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The resilient detents and deformable barbs automatically engage with the conduit upon insertion and self-adjust to provide optimal gripping force, eliminating the need for manual adjustment or complex control systems while ensuring reliable retention

Inventive Principle:

Principle #25Self-service
