Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If voltage, current, or frequency is varied to control ozone generation, then the amount of ozone generated changes, but the power delivery becomes unstable and unpredictable
Solution Approach 1:
The patent implements a feedback control system that continuously monitors the actual power delivered to the ozone generation cell and adjusts the power supply parameters accordingly. The controller compares the measured power with the target power level and dynamically adjusts voltage, current, or frequency to maintain stable and predictable power delivery while controlling ozone generation rate.
Solution Approach 2:
The patent changes the control parameter from directly controlling voltage, current, or frequency to controlling the power delivered to the cell. By using power as the primary control parameter and allowing voltage, current, and frequency to vary as secondary parameters adjusted by the feedback system, the patent achieves both stable power delivery and controlled ozone generation.
2Productivity
If higher power levels are delivered to the cell, then the amount of ozone generated increases, but the efficiency of converting oxygen to ozone decreases
Solution Approach 1:
The patent employs dynamic control of power delivery parameters rather than fixed settings. The feedback control system continuously adjusts voltage, current, and frequency based on real-time cell conditions, allowing the system to operate at optimal efficiency points across varying production requirements. This dynamic adjustment enables the system to maintain high conversion efficiency even when operating at different power levels.
3Manufacturing precision
If precise dosing of ozone is required for water disinfection, then the power supply must vary in a precise and repeatable way, but the unstable electrical characteristics of the cell make this difficult
Solution Approach 1:
The feedback control system continuously monitors power delivery and automatically adjusts parameters to maintain precise and repeatable operation. This closed-loop control compensates for the unstable electrical characteristics of the cell, providing accurate ozone dosing without requiring complex manual adjustment mechanisms or multiple separate control systems.
Solution Approach 2:
The power supply system is designed to perform multiple functions through a single integrated control mechanism. The same feedback control system that stabilizes power delivery also ensures precise dosing, eliminates the need for separate control systems for different operational requirements, and simplifies the overall device architecture while maintaining high precision.

Implementation Method 1
A power supply system that measures and adjusts the rate of energy delivery to the ozone generation cell, using feedback loops and control mechanisms to maintain a constant energy delivery rate
Implementation Method 2
One ozone generation method is the corona discharge cell. A corona discharge cell generally comprises two electrodes having a dielectric material sandwiched therebetween. Additionally, a space is present between the two electrodes. Specifically, when generating ozone, oxygen gas is passed into a space between two electrodes that are spaced apart by a dielectric material. The ozone is generated in the space.

AI summary
The present invention generally includes an ozone generation system with a power supply that measures the rate of energy delivered to the ozone generation cell. While changing voltage, frequency or current will likely affect the rate of energy delivery, current, frequency and voltage provide a very poor and unreliable control for an ozone generation cell. It is only through control of the rate of energy delivery that consistent, reliable ozone generation is possible. Based upon the measurements of the rate of energy delivery as measured at the ozone generation cell, compared to the rate of energy delivery supplied, the rate of energy delivery supplied can be adjusted to improve ozone production and control.
