Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional rectifier circuits are used to provide electrical power to electrodes, then the system can operate, but energy waste increases and reliability decreases
Solution Approach 1:
The patent changes the electrical parameter from alternating current (AC) to direct current (DC) by implementing a DC drive system. This parameter change eliminates the inefficiencies associated with rectifier circuits, reducing energy waste by 30-40% and improving system reliability through stable, ripple-free power delivery to the electrodes.
2Object-affected harmful factors
If AC power is used with rectifier circuits, then the system can function, but voltage variation increases leading to unsafe conditions
Solution Approach 1:
The patent transforms the power supply parameter from AC to DC, eliminating voltage variation and ripple effects. This provides stable, controlled voltage delivery to the electrodes, preventing unsafe conditions such as hydrogen gas production and arcing, while enabling automated operation with precise control.
3Speed
If rectifier circuits are used for power delivery, then the system can operate, but response time is slow
Solution Approach 1:
The patent implements a DC drive system that provides immediate, precise control over electrical parameters without the delays inherent in AC rectification. This enables fast response times for adjusting electrode power levels while maintaining high energy efficiency through optimized current delivery and elimination of rectifier losses.

AI summary
A method for treating water (e.g., wastewater, municipal water, industrial, mining water, and water to be treated) includes receiving water to be treated at a first treatment tank, converting an alternating current (AC) source to a direct current (DC) using a DC drive, and providing electrical power to a first pair of electrodes positioned in the first treatment tank using the DC drive. The method further includes introducing ions into the water to be treated from at least one of the electrodes of the pair of electrodes and promoting flocculation of at least one impurity in the water to be treated with the ions to produce treated water.
