Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If localized leak detection devices with audible alarms are used, then water leak detection is provided, but remote monitoring is impractical because observers must be in arms-length from the device
Solution Approach 1:
The patent replaces the mechanical audible alarm system with an electronic notification system that transmits leak detection data remotely via communication networks (wireless or wired) to remote devices such as smartphones or computers, enabling observers to monitor leaks from any location without being physically near the detector
Solution Approach 2:
The patent introduces a communication network as an intermediary between the leak detection device and the observer, allowing notification data to be transmitted through wireless or wired networks to remote devices, thus bridging the physical gap between the detector and the observer
2Measurement precision
If closed-circuit type detectors with solid-state circuitry are used, then electrical path detection is provided, but small amounts of water or moisture are extremely difficult to detect
Solution Approach 1:
The patent changes the detection parameter from electrical conductivity (closed-circuit method) to optical properties (light absorption or scattering by water molecules), enabling detection of much smaller amounts of water or moisture that do not conduct electricity but do affect light transmission
Solution Approach 2:
The patent uses specific optical wavelengths or frequencies that are particularly sensitive to water molecules, enhancing the local detection capability for trace moisture while maintaining system simplicity
3Reliability
If conventional automated water leak detection systems with multiple status indicators are used, then water leak detection is provided, but the systems are expensive, complex, and difficult to install
Solution Approach 1:
The patent creates a universal notification device that can work with various types of sensors and communication networks, and can be installed in different locations (residential or commercial) without requiring complex custom configurations, thereby simplifying installation while maintaining reliability
Solution Approach 2:
The patent divides the system into separate functional modules (sensor module, communication module, notification module) that can be installed and configured independently, reducing overall system complexity and making installation easier while maintaining detection reliability
4Measurement precision
If centralized monitoring with point identification data is implemented, then precise leak location identification is provided, but response time for large buildings is still delayed
Solution Approach 1:
The patent pre-configures the system with multiple notification channels and automatic alert protocols that are immediately activated upon leak detection, sending notifications through multiple pathways simultaneously (push notifications, SMS, email) to ensure the fastest possible response time while maintaining precise location identification

AI summary
The present invention provides a water leak detection system for detecting water leaks in residential and commercial buildings or constructions. The water leak detection system provides central monitoring and point identification data of water leaks. The water detection system includes a plurality of address modules connected to a plurality of sensors for assigning an identifier to each sensor. The address modules are in wired or wireless communication with a central control unit, which processes detected sensor signals and notifies an alarm annunciator of point identification data of a water leak. The alarm annunciator provides visual and/or audible indications of where a water leak has been detected. The central control unit and/or alarm annunciator further operate a valve associated to the sensor in order to revert the water leak detection. The central control unit can further communicate the detection to a remote equipment, via a wired or wireless network communication.
