Solution Overview

Problem

Existing flexible conduits are prone to breaking under strong forces and may sag undesirably due to their rigid anchoring systems, which can be dangerous and unappealing, and lack adjustable disengagement forces and secondary support mechanisms.

Innovation Solution

A flexible conduit with a releasable connector system comprising a female and male member with biased plungers and detents, allowing adjustable force disengagement and secondary cable support to prevent breakage and accommodate movement, while maintaining support and flexibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If rigid anchoring rods are used to support the flexible conduit, then the conduit is securely supported, but the conduit may break under strong forces and cannot accommodate movement

Engineering Contradiction:
Improvesupport strengthVSAvoidconduit safety
Core Design Contradiction:
StrengthVSReliability

Solution Approach 1:

The anchoring system is divided into a rigid support structure and a separate releasable connector mechanism. The releasable connector includes a body, shaft, biased plunger, and detent that can disengage independently when subjected to excessive force, preventing conduit breakage while maintaining secure support during normal operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The releasable connector transforms the static rigid anchoring into a dynamic system that can adapt to force conditions. The biased plunger and detent mechanism automatically engages during normal operation to provide secure support, but disengages when excessive force is applied, allowing the system to respond dynamically to changing load conditions.

Inventive Principle:
Principle #15Dynamics

2Stability of the object's composition

If rigid anchoring rods are used to support the flexible conduit, then the conduit is securely supported, but the conduit is prevented from bending and flexing

Engineering Contradiction:
Improveconduit stabilityVSAvoidconduit flexibility
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The support system is segmented into a fixed mounting point and a movable releasable connector that attaches to the flexible conduit. This segmentation allows the conduit to maintain flexibility and bend as needed while the connector provides stability when engaged, and the ability to disconnect when flexibility is required.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system changes the support parameter from constantly rigid to conditionally rigid. During normal operation, the releasable connector provides stable support, but when movement or bending is required, the connector can be disengaged to restore full flexibility to the conduit system.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If the flexible conduit is allowed to move freely, then the conduit can accommodate thermal changes and vibration, but the conduit sags undesirably

Engineering Contradiction:
Improveconduit movement capabilityVSAvoidconduit sagging
Core Design Contradiction:
Adaptability or versatilityVSShape

Solution Approach 1:

The releasable connector creates a dynamic support system that transitions between engaged and disengaged states. When engaged, it provides upward support force to counteract gravity and prevent sagging. When disengaged, it allows the conduit to move freely to accommodate thermal expansion, contraction, and vibration without restriction.

Inventive Principle:
Principle #15Dynamics

4Reliability

If a releasable connector with biased plunger and detent is used, then the conduit can disengage under certain forces to prevent breakage, but the device complexity increases

Engineering Contradiction:
Improveconduit safetyVSAvoidconnector complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The releasable connector is designed as a self-actuating mechanism where the biased plunger automatically engages with the detent during assembly and self-disengages when excessive force is applied. This eliminates the need for external actuators, controls, or complex operation mechanisms, achieving conduit protection through a simple passive mechanical design.

Inventive Principle:
Principle #25Self-service

AI summary

A flexible conduit having a rigid portion, a flexible portion and a releasable connector secured to the rigid portion to support the flexible conduit. The releasable connector includes a male member and a female member. One of the two members includes at least one biased plungers and the other includes at least one detent. The plungers and detents are vertically spaced along the longitudinal axes of the members. A clevis may be used to secure the releasable connector to the rigid portion of the flexible conduit. A second support connected to the male and female members may be used. Also a method of supporting a flexible conduit with a releasable connector.
