Solution Overview

Problem

Existing centralizers for pipe tools require labor-intensive installation and removal, are limited in size adaptability, and fail to maneuver effectively through bends and turns, leading to increased material and labor costs, job duration, and frustration.

Innovation Solution

A centralizer apparatus with a truncated bi-cone shape that can be installed from the side of a guide hose, adaptable for various sizes, and designed to maneuver through bends and turns with reduced snagging, using interchangeable finger sets and optional rubberized gripping elements for enhanced clamping.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional centralizers are used that require attachment to the end of the guide hose, then the centralizer can provide stable centering, but the installation and removal process becomes labor-intensive and increases job duration

Engineering Contradiction:
ImproveInstallation easeVSAvoidJob duration
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The centralizer is divided into modular components including interchangeable finger sets that can be quickly changed without removing the entire centralizer from the guide hose, enabling rapid adaptation to different hose diameters and reducing installation time

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The centralizer incorporates flexible fingers that can dynamically adjust their position and configuration to accommodate different guide hose diameters and navigate bends, providing both ease of installation and stable centering through adaptive geometry rather than fixed rigid structures

Inventive Principle:
Principle #15Dynamics

2Reliability

If multiple centralizer sizes are maintained for different guide hose diameters, then each centralizer can provide optimal centering for its specific size, but material costs and inventory complexity increase

Engineering Contradiction:
ImproveCentering accuracyVSAvoidSize adaptability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The centralizer design incorporates interchangeable finger sets that can be configured to accommodate multiple guide hose diameters, allowing a single centralizer body to perform multiple sizing functions and eliminating the need to maintain separate centralizers for each hose size

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

Solution Approach 2:

The flexible finger configuration allows the centralizer to dynamically adapt its internal diameter to match different guide hose sizes, providing optimal centering accuracy across multiple diameters through a single versatile device rather than requiring multiple fixed-size centralizers

Inventive Principle:
Principle #15Dynamics

3Reliability

If rigid centralizer structures are used to maintain stable centering, then centering precision is improved, but the ability to maneuver through bends and turns is reduced

Engineering Contradiction:
ImproveCentering stabilityVSAvoidManeuverability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The centralizer employs flexible fingers that can bend and deform as the guide hose navigates turns and bends, allowing the centralizer to maintain its centering function while adapting to the changing geometry of the piping system, thus preserving both stability and maneuverability

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The centralizer incorporates flexible finger elements that can deform and conform to the curvature of bends in the guide hose, enabling the rigid centering function to operate effectively even when the overall structure must flex to navigate turns

Inventive Principle:
Principle #30Flexible shells and thin films

4Ease of operation

If the centralizer has a tight-fitting design to reduce snagging, then maneuverability through bends is improved, but the ability to provide adequate clamping force is reduced

Engineering Contradiction:
ImproveManeuverabilityVSAvoidClamping force
Core Design Contradiction:
Ease of operationVSForce

Solution Approach 1:

The flexible fingers can dynamically adjust their clamping force by deforming under load, allowing the centralizer to maintain adequate holding force on the guide hose while still permitting the necessary flexibility to navigate bends without excessive snagging

Inventive Principle:
Principle #15Dynamics
