Solution Overview

Problem

Calibrating and maintaining sensors embedded in large flanges of fluid processing systems, such as hydrate inhibitor reclamation systems in oil and gas production, is time-consuming and labor-intensive due to the need to remove and replace the entire flange.

Innovation Solution

A removable adaptor is designed to embed sensors in flanges, allowing the sensor to be removed and calibrated or replaced without taking the flange off the pipe, thereby reducing the time and labor required for maintenance and calibration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the entire flange is removed for sensor calibration or maintenance, then the sensor can be accessed, but the time and labor required for the process increases significantly

Engineering Contradiction:
Improvesensor accessibilityVSAvoidcalibration time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The flange assembly is segmented into two independent parts: the main flange body that remains installed on the pipe, and a removable adaptor that houses the sensor. This segmentation allows the sensor-containing adaptor to be accessed, removed, and calibrated independently without disturbing the main flange, thereby reducing calibration time and labor while maintaining sensor accessibility

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sensor is extracted from the main flange structure and placed within a separate removable adaptor. This extraction allows the sensor to be taken out for calibration or replacement by simply removing the adaptor from the flange, eliminating the need to remove the entire flange and significantly reducing the time and effort required for sensor maintenance

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of repair

If the entire flange is removed for sensor maintenance, then the sensor can be replaced, but the labor and time requirements increase

Engineering Contradiction:
Improvesensor replaceabilityVSAvoidmaintenance efficiency
Core Design Contradiction:
Ease of repairVSProductivity

Solution Approach 1:

The flange assembly is divided into a stationary main flange and a movable adaptor component. This segmentation enables the adaptor (containing the sensor) to be independently removed and replaced through a simplified interface, making sensor replacement easier and more efficient without requiring removal of the entire flange structure

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sensor is extracted into a separate removable adaptor that can be independently manipulated. This allows the sensor to be replaced by simply exchanging the adaptor unit, significantly improving ease of repair and maintenance efficiency compared to removing the entire flange assembly

Inventive Principle:
Principle #2Taking out (Extraction)
