Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Homeowners face challenges in detecting leaks in water pipes and devices promptly, leading to potential structural damage, increased utility costs, and inefficiencies in water heating systems due to unnoticed leaks over time.
Innovation Solution
A home energy management system with a central controller that communicates with water meters to track water flow and alerts homeowners via display, text message, or other methods when water consumption exceeds predetermined thresholds, allowing for timely detection and mitigation of leaks.

Engineering Contradiction Analysis
1Reliability
If water meters and monitoring systems are installed to detect leaks, then leak detection capability is improved, but device complexity increases
Solution Approach 1:
The existing water meter is enhanced to serve multiple functions: it continues to measure water consumption for billing purposes while simultaneously monitoring for leak conditions by detecting continuous flow patterns. This multi-functionality improves leak detection capability without requiring a completely separate dedicated leak detection device, thereby limiting the increase in system complexity.
Solution Approach 2:
The system utilizes the water meter's own operational data and existing infrastructure to perform leak detection, rather than requiring entirely external monitoring equipment. The controller analyzes flow data already being collected for billing purposes, allowing the system to self-monitor for leaks using resources already in place, thus improving detection capability while minimizing additional complexity.
2Measurement precision
If continuous water flow monitoring is implemented to detect small leaks, then measurement precision is improved, but use of energy increases
Solution Approach 1:
Instead of continuously monitoring water flow at maximum precision, the system employs periodic sampling of flow data at strategically selected intervals. The controller compares flow measurements taken at different times to identify patterns indicative of leaks. This periodic approach maintains sufficient measurement precision for detecting anomalies while significantly reducing the energy consumption associated with constant high-precision monitoring.
Solution Approach 2:
The system applies enhanced measurement precision selectively rather than uniformly across all monitoring moments. Normal flow conditions are monitored with standard precision, while suspicious patterns or threshold violations trigger more intensive measurement and analysis. This partial application of high-precision monitoring maintains adequate leak detection capability while minimizing the overall energy expenditure required for continuous high-precision surveillance.
Data Source
AI summary
Methods and systems are disclosed for monitoring water leaks within a home. A home network with various devices monitors these devices with a controller. Information is received from a water flow meter via a transceiver for tracking a total water flow amount through pipelines in the home. By comparing information collected to a predetermined threshold, a leak is determined as present or not within each pipeline. Upon the detection of a leak in the home, a home owner is notified of the condition so that action is taken expeditiously. A shut off valve can be triggered remotely when a request is received from the user, which closes the water pipeline to prevent water damage.
