Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If automated water control systems are installed, then water leak detection and control capability is improved, but installation complexity and requirement for external power supply increases

Engineering Contradiction:
Improvewater leak detection capabilityVSAvoidinstallation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system uses self-powered operation where the water flow itself generates electrical energy through a hydroelectric generator to power the monitoring electronics, eliminating the need for external power supplies and complex installations. The device serves itself by using the resource being monitored (water flow) to power the monitoring system.

Inventive Principle:
Principle #25Self-service

2Reliability

If remote water detection sensors are deployed, then leak detection coverage is improved, but system complexity and power requirements increase

Engineering Contradiction:
Improveleak detection coverageVSAvoidpower consumption
