Solution Overview

Problem

Existing leak detection systems are cumbersome, require constant vigilance, are ineffective in power outages, and are costly for multiple locations, as they often need AC power and special wiring, and do not provide remote notification capabilities.

Innovation Solution

A self-powered, modular leak detection system with water-activated batteries and wireless communication that uses Bluetooth Low Energy technology for remote notification, eliminating the need for special wiring and AC power, and allowing for expansion to multiple locations with ease.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If AC powered leak detection units are used, then continuous operation is achieved, but the system becomes useless in power outages and requires special wiring

Engineering Contradiction:
Improvecontinuous operationVSAvoidspecial wiring requirement
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The leak detection device uses a water-activated battery that generates power autonomously when water is detected. The battery components (magnesium anode, carbon cathode, salt electrolyte) are sealed and self-contained, requiring no external power source, wiring, or user intervention to activate or maintain power supply.

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If multiple complete leak detection devices are deployed for multiple locations, then comprehensive coverage is achieved, but the cost increases significantly

Engineering Contradiction:
Improvemulti-location coverageVSAvoidtotal system cost
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The system is divided into two functional segments: a reusable wireless communication hub that remains stationary, and multiple disposable leak detection sensors that can be deployed independently. Each sensor contains the water-activated battery and detection mechanism, while the hub handles wireless communication and alert notification, allowing sensors to be added or removed without replacing the entire system.

Inventive Principle:
Principle #1Segmentation

3Reliability

If traditional leak detection units are installed, then leak detection capability is provided, but the units are cumbersome and require constant vigilance for battery status

Engineering Contradiction:
Improveleak detection capabilityVSAvoidmaintenance requirement
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The leak detection sensor is designed as a disposable unit with a sealed water-activated battery that provides power for the device's operational lifetime. Once the battery is depleted or the sensor malfunction, the entire unit is discarded and replaced, eliminating all maintenance activities including battery replacement, charging, or status monitoring.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

4Loss of information

If remote notification capability is added to leak detection devices, then timely alerts are achieved, but the device complexity and power requirements increase

Engineering Contradiction:
Improvenotification timelinessVSAvoidcommunication system requirement
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The system replaces complex wired communication infrastructure with simple wireless communication. The sensor unit transmits leak alerts wirelessly to a hub, which then notifies occupants via smartphone app, email, or text message. This eliminates the need for hardwired communication systems, phone lines, or internet infrastructure at the sensor location.

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

AI summary

A modular leak detection and notification unit comprised of a self powered leak sensor and a remote relay transmitter. It presents a local audible alarm and a text alarm message signaling the location of the leak to the all cell phones/smart devices that it is directed to notify. Notification may be routed in two different ways via the internet and RF transmission. It can accommodate any number of leak sensors, that can be positioned at a plethora of different potential leak sites.
