Solution Overview

Problem

Fire sprinkler systems, particularly wet pipe systems, are vulnerable to freezing temperatures and corrosion, which can lead to system failure and costly damage, and existing monitoring methods are inadequate for detecting breaches before they result in significant damage.

Innovation Solution

A corrosion monitoring system is implemented in fire sprinkler systems by creating a sealed chamber between a pipe portion with a reduced wall thickness and a sensor, which detects pressure changes or liquid presence, allowing for early detection of breaches and preventive action.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a wet pipe sprinkler system is used, then fire protection coverage is improved, but vulnerability to freezing temperatures increases

Engineering Contradiction:
Improvefire protection coverageVSAvoidfreezing temperature vulnerability
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a corrosion monitoring assembly as an intermediary device between the water supply and the sprinkler system. This assembly includes a sealed chamber with a sensor that detects corrosion products or changes in water quality, serving as an early warning system that mediates between the potential harm of freezing/corrosion and the need for reliable fire protection.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The corrosion monitoring assembly performs preliminary detection of corrosion and water quality changes before they lead to system failure. By detecting early signs of corrosion or freezing conditions, the system enables preventive actions to be taken before the actual harm occurs, maintaining reliability while mitigating vulnerability.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If existing monitoring methods are used, then system operation is maintained, but detection of breaches before damage occurs is insufficient

Engineering Contradiction:
Improvesystem operationVSAvoidbreach detection capability
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent replaces traditional mechanical monitoring methods with electronic sensors that can detect corrosion products, pressure changes, or other indicators of impending failure. These electronic detection systems provide more precise measurement capabilities compared to conventional mechanical gauges or visual inspection methods.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The sealed chamber in the corrosion monitoring assembly acts as an intermediary that concentrates or amplifies corrosion products, making them detectable by the sensor. This intermediary mechanism enhances the detection capability by creating a focused detection zone that improves measurement precision for early breach detection.

Inventive Principle:
Principle #24Intermediary (Mediator)
