Solution Overview

Problem

The existing methods for installing electronic devices in pipes where fluids circulate, such as natural gas, are cumbersome, require cutting off gas flow, use bulky systems that need external power, and are costly, limiting their installation in inaccessible locations and reducing the number of sensors that can be deployed in meshed gas distribution networks.

Innovation Solution

A system comprising an electronic device with a threaded body and punch that allows simultaneous insertion and drilling into the pipe while maintaining a seal, using a sleeve with a conduit opening onto the pipe wall, and an on-board energy source for autonomous operation, enabling easy installation and wireless communication without the need for wired connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional electronic systems are used for pipe installation, then measurement accuracy is improved, but device size becomes too large for inaccessible locations

Engineering Contradiction:
Improvemeasurement accuracyVSAvoiddevice size
Core Design Contradiction:
Measurement precisionVSVolume of moving object

Solution Approach 1:

The device is divided into distinct functional components: a body for structural support, a punch for hole formation, an electronic module for measurements, and a threaded portion for installation. This segmentation allows each component to be optimized independently, enabling accurate measurements in a compact form factor suitable for inaccessible pipe locations.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If traditional electronic systems are installed in pipes, then measurement capability is improved, but installation complexity increases due to gas flow interruption requirements

Engineering Contradiction:
Improvemeasurement capabilityVSAvoidinstallation complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The threaded portion is pre-formed on the device body, allowing it to be screwed directly into the pipe without requiring separate installation steps. The punch is integrated into the body, enabling hole formation and device insertion to occur simultaneously. These preliminary design actions eliminate the need for gas flow interruption and complex multi-step installation procedures.

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If traditional electronic systems are deployed, then measurement coverage is improved, but installation cost increases due to external power supply requirements

Engineering Contradiction:
Improvemeasurement coverageVSAvoidinstallation cost
Core Design Contradiction:
Measurement precisionVSEase of manufacture

Solution Approach 1:

The device is designed to be self-contained, with the electronic module powered directly by the pipe's operational environment or integrated power sources within the device itself. This eliminates the need for external power supplies and complex wiring infrastructure, significantly reducing installation costs while maintaining measurement coverage across multiple pipe locations.

Inventive Principle:
Principle #25Self-service

4Loss of information

If more sensors are installed in the network, then flow understanding is improved, but installation accessibility becomes limited

Engineering Contradiction:
Improveflow understandingVSAvoidinstallation accessibility
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The device transitions from requiring external access points to being insertable through the pipe wall itself via the integrated punch mechanism. This dimensional change in installation approach allows sensors to be placed in previously inaccessible locations, enabling comprehensive flow monitoring across the entire network without being constrained by external accessibility.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
