Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an external source of water vapor is used, then hydrogen peroxide generation is achieved, but device cost increases
Solution Approach 1:
The patent merges the water vapor generation function with the rotating electrode by forming the electrode as a hollow rotor that receives water internally. The rotation of the electrode itself generates centrifugal force to convert water to vapor and deliver it to the corona discharge zone, eliminating the need for external vapor sources and reducing device complexity and cost.
Solution Approach 2:
The rotating electrode performs multiple functions simultaneously: it serves as one of the electrodes generating the corona discharge zone, acts as a water vapor converter through centrifugal force, and functions as a vapor delivery mechanism. This multi-functionality reduces the number of separate components needed, thereby reducing device cost and complexity.
2Reliability
If an air capacitor is used for high voltage AC transmission, then high voltage AC can be conveyed to the rotating electrode, but construction becomes complicated and frequency is limited
Solution Approach 1:
The patent extracts and eliminates the air capacitor from the system by finding an alternative transmission path. High voltage AC is transmitted directly through the water feeding channel and the rotating electrode itself, which are made electrically conductive, removing the need for the air capacitor and its associated construction complexities and frequency limitations.
Solution Approach 2:
The water feeding channel and rotating electrode serve as an intermediary transmission medium for high voltage AC. By making these components electrically conductive, they directly conduct high voltage from the stationary power source to the rotating electrode, replacing the air capacitor's function with a simpler conductive path.
3Reliability
If water is converted to vapor externally, then hydrogen peroxide generation is achieved, but additional equipment is required
Solution Approach 1:
The patent combines the water vapor conversion function with the rotating electrode structure. The hollow rotor receives water internally and uses its rotation to generate centrifugal force for vaporization, merging what would have been separate external equipment into a single integrated component.
Solution Approach 2:
The rotating electrode serves itself by using its own rotation to generate the centrifugal force needed for water vaporization and delivery. This self-service mechanism eliminates the need for separate external vapor conversion equipment, reducing the total number of components required.

This approach simplifies and reduces the cost of hydrogen peroxide generation by integrating functions within the device, cooling electrodes through adiabatic conversion and enabling high voltage transmission, resulting in efficient and cost-effective hydrogen peroxide production.
Implementation Method 1
converting water to vapor immediately prior to conveying the vapor through the corona discharge zone serves to cool the electrodes by 2 to 5° C. owing to the water to vapor conversion which is an adiabatic process
Implementation Method 2
water is converted to vapor due to water encountering the electrode rotating at a high speed which is brought to the corona discharge zone by the centrifugal force generated by the electrode
Implementation Method 3
corona discharge zone generated between a rotating electrode formed as a hollow rotor of a centrifugal fan and a fixed electrode
Implementation Method 4
The water level in the channel is raised by a rotating screw thread mounted inside the channel on the lower end of the rotating electrode
Implementation Method 5
enables high voltage from the AC high voltage source to be conducted through the water feeding channel to the rotating electrode. This requires forming the rotating electrode and the water feeding channel from electrically conductive materials
