Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional choke systems are often inefficient, leading to higher manufacturing and operating costs due to oversized components, and fail to effectively pass larger debris without increasing the intake dimension.

Innovation Solution

The choke system is designed with reduced dimension 1 and increased dimensions 2 and 3, allowing larger debris to pass while maintaining acceptable fluid dynamics, and incorporating specific ring configurations and seal systems to manage backpressure and prevent leaks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional choke systems use larger intake dimensions to pass larger debris, then debris passage capability is improved, but manufacturing costs and operating costs increase due to oversized components

Engineering Contradiction:

Improvedebris passage capabilityVSAvoidmanufacturing costs

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The choke system is divided into multiple channels: a first channel for fluid flow and a second channel for debris passage. This segmentation allows the debris channel to be optimized independently for passing large debris while the fluid channel maintains efficient flow characteristics, avoiding the need to oversize the entire choke system.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention introduces a vertical dimension to debris passage by allowing debris to pass through the second channel in a direction substantially perpendicular to the fluid flow direction. This dimensional change enables large debris to pass through without increasing the horizontal intake dimension, thereby reducing manufacturing costs.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If conventional choke systems use larger intake dimensions to pass larger debris, then debris passage capability is improved, but fluid dynamics efficiency deteriorates

Engineering Contradiction:

Improvedebris passage capabilityVSAvoidfluid dynamics efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different parts of the choke system have different optimized characteristics: the first channel is optimized for fluid flow efficiency with smooth transitions and appropriate sizing, while the second channel is optimized for debris passage with vertical orientation and sufficient clearance. This local optimization ensures both fluid dynamics efficiency and debris passage capability.

Inventive Principle:

Principle #3Local quality

3Ease of manufacture

If choke systems reduce component sizes to lower costs, then manufacturing costs are reduced, but capability to pass larger debris deteriorates

Engineering Contradiction:

Improvemanufacturing costsVSAvoiddebris passage capability

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The second channel for debris passage is nested within or alongside the first channel for fluid flow. This nesting arrangement allows the debris passage pathway to be integrated into the existing choke structure without requiring additional external space, enabling large debris passage while maintaining compact overall dimensions.

Inventive Principle:

Principle #7Nested doll (Nesting)

4Adaptability or versatility

If adjustable chokes are used to control fluid flow, then flow control flexibility is improved, but wear resistance deteriorates under prolonged operation with abrasive fluids

Engineering Contradiction:

Improveflow control flexibilityVSAvoidwear resistance

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The choke system separates the adjustable flow control function (first channel with adjustable choke) from the debris passage function (second channel). This segmentation protects the adjustable choke components from direct exposure to large debris and abrasive materials, reducing wear while maintaining flow control flexibility.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The second channel acts as an intermediary pathway that handles debris and abrasive materials separately from the main fluid flow path. This intermediary channel protects the adjustable choke components in the first channel from direct contact with abrasive substances, extending their service life while maintaining flow control capabilities.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

Embodiments include a choke system that passes enlarged debris despite having a relatively small diameter for an input port of the choke system. Embodiments also include systems to prevent dislodging of a choke seat when backpressure is supplied to the choke system. Embodiments also include sealing systems to prevent fluid leaks around the choke seat of the choke system.
