Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electromechanical switches are used to monitor water flow, then flow detection function is achieved, but system reliability deteriorates due to frequent failures
Solution Approach 1:
The patent replaces electromechanical switches with an electronic detection system that monitors water flow by measuring voltage changes across the electrolysis cell blades. This substitution eliminates mechanical moving parts that are prone to failure, thereby improving system reliability while maintaining the flow detection function through electrical measurements.
Solution Approach 2:
The system uses the electrolysis cell itself as the sensing element by monitoring voltage changes that occur naturally during electrolysis when water flow varies. This self-service approach eliminates the need for separate flow detection devices, reducing device complexity while improving reliability through the inherent properties of the electrolysis process.
2Object-affected harmful factors
If electromechanical switches are used for flow monitoring, then flow detection is achieved, but safety deteriorates due to failure risks
Solution Approach 1:
The patent replaces electromechanical switches with an electronic monitoring system that detects water flow through voltage measurements across the electrolysis cell. This substitution eliminates the reliability issues of mechanical components, thereby improving safety by ensuring continuous adequate water flow across the electrodes without failure-prone mechanical parts.
3Reliability
If electronic fluid flow detection system is implemented, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent makes the electrolysis cell serve dual functions: both electrolysis for chlorine generation and flow detection through voltage monitoring. By using the same component for multiple purposes, the system improves flow detection reliability without adding separate detection devices, thereby avoiding increased device complexity.
Solution Approach 2:
The electrolysis cell performs self-diagnosis by generating voltage signals that indicate water flow conditions. This self-service capability allows the system to monitor its own operational status without external sensors, improving reliability while maintaining simplicity in the overall device architecture.
