Water Pressure Alarm with Time-Delayed Threshold Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High water pressure in plumbing systems can cause damage to fixtures and appliances, and existing monitoring devices primarily focus on low pressure fluctuations, neglecting the potential for high pressure spikes that can lead to premature failure and leaks.
Innovation Solution
A device and system that includes a pressure sensor connected to a controller and timer, which triggers notifications, such as alerts or electronic signals, when high pressure exceeds a selected threshold for a set time, allowing for early detection and prevention of damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous pressure monitoring is implemented, then damage prevention capability is improved, but energy consumption increases
Solution Approach 1:
The system implements periodic pressure sampling rather than truly continuous monitoring. The controller periodically reads the pressure sensor value and compares it against threshold values. The notification is triggered only when high pressure conditions persist for a predetermined time period, reducing energy consumption while maintaining effective damage prevention capability.
Solution Approach 2:
The system provides self-monitoring and self-notification capabilities. The controller automatically compares pressure readings against thresholds and triggers notifications without requiring external intervention. The predetermined time delay feature automatically filters out transient pressure spikes, providing intelligent self-service pressure management.
2Measurement precision
If high pressure alarm threshold is set low, then sensitivity to high pressure events is improved, but false alarm rate increases
Solution Approach 1:
The system implements a predetermined time delay before triggering the high pressure notification. When pressure exceeds the second threshold value, the controller waits for the predetermined time period to elapse before activating the notification. This preliminary time-based action allows transient pressure fluctuations to resolve themselves, significantly reducing false alarms while maintaining sensitivity to sustained high pressure events that could cause damage.

AI summary
A device and system for sensing high pressure in a pressurized water system. The high pressure alarm includes a pressure sensor, controller, and timer. A method of installing a high pressure alarm on a pressurized water system. The high pressure alarm is particularly well-suited for installing under a sink, such as a home kitchen sink, though it can also be installed near other plumbing fixtures or appliances in commercial, residential, or industrial facilities and in outside areas.
