Solution Overview

Problem

Homeowners face significant damage and repair costs due to burst pipes when fluids in pipes freeze and thaw, as existing manual prevention methods are inefficient and wasteful.

Innovation Solution

A fluid management system that uses temperature sensors and a controller to detect freezing onset events, triggering recirculation pumps and heating devices to prevent freezing, and notifying users of imminent freezing or thawing, thereby reducing the need for manual intervention and energy wastage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual prevention techniques are used to prevent pipe freezing, then pipe freezing can be prevented, but energy wastage and operational inconvenience increase

Engineering Contradiction:
Improvepipe freezing preventionVSAvoidenergy wastage
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The system performs preliminary detection of freezing conditions using temperature sensors and predicts freezing onset before it occurs. By activating prevention measures (heating elements, recirculation pumps) only when freezing is imminent rather than continuously or manually, the system prevents pipe freezing while minimizing energy consumption compared to manual techniques like keeping faucets open or continuously heating.

Principle #10Preliminary action

2Reliability

If manual prevention techniques are used to prevent pipe freezing, then pipe freezing can be prevented, but operational complexity and user burden increase

Engineering Contradiction:
Improvepipe freezing preventionVSAvoiduser burden
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system enables self-service by automatically detecting freezing conditions through temperature sensors, analyzing temperature profiles to predict freezing onset, and activating appropriate prevention measures without user intervention. The controller autonomously manages the entire prevention process, eliminating the need for homeowners to manually turn off water mains, adjust thermostats, or monitor pipe conditions.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements feedback by continuously monitoring pipe temperature through sensors, comparing actual temperatures against predicted freezing thresholds, and automatically adjusting prevention measures based on real-time conditions. This closed-loop control ensures reliable freezing prevention while adapting to changing environmental conditions without requiring user input.

Inventive Principle:
Principle #23Feedback

3Measurement precision

If temperature monitoring is performed continuously to detect freezing onset, then freezing can be detected early, but system complexity and cost increase

Engineering Contradiction:
Improvefreezing detection accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system performs preliminary detection by monitoring temperature trends and predicting freezing onset before actual freezing occurs. Rather than requiring complex continuous monitoring throughout the entire pipe system, temperature sensors placed at strategic locations track temperature profiles over time and use predictive algorithms to identify freezing conditions early, achieving high detection accuracy with moderate system complexity.

Inventive Principle:
Principle #10Preliminary action

AI summary

According to an example, a system for managing a fluid condition in a pipe includes a controller to receive temperatures of the pipe detected by the temperature sensor over a period of time. The controller may determine, based upon the temperatures of the pipe over the period of time, a temperature profile of the pipe and may determine that the temperature profile of the pipe indicates that a freezing onset event has occurred. The freezing onset event may include a transition from a drop in temperature to an increase in temperature, in which the temperature during the transition is below a freezing point temperature of a fluid contained in the pipe. The controller may further trigger at least one of an alarm and an activation of a first freezing prevention device in response to the determination that the freezing onset event has occurred.
