Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the ozone generator is operated below maximum capacity, then energy consumption is reduced, but ozone yield becomes suboptimal
Solution Approach 1:
The patent applies dynamics by making the current pulse parameters (amplitude and frequency) adjustable and adaptive rather than fixed. The control system dynamically modifies these parameters based on real-time feedback from ozone concentration sensors and energy consumption monitors, allowing the system to optimize ozone yield at any operating capacity level rather than being locked into fixed operating points
Solution Approach 2:
The patent implements feedback control by continuously monitoring ozone concentration levels and energy consumption, then using this information to adjust current pulse amplitude and frequency. The control system compares actual performance against target values and automatically modifies operating parameters to maintain optimal ozone yield while minimizing energy consumption across varying capacity levels
2Productivity
If current amplitude is increased to improve ozone production rate, then productivity increases, but energy consumption increases proportionally
Solution Approach 1:
The patent applies parameter changes by independently adjusting both current pulse amplitude and frequency to optimize the ratio of ozone production to energy consumption. Rather than simply increasing amplitude to boost production, the system can modify frequency or combine amplitude-frequency adjustments to achieve higher productivity with proportionally lower energy increase, thereby improving overall efficiency
Solution Approach 2:
The patent utilizes periodic pulsed corona discharges instead of continuous operation. By controlling the frequency and duration of current pulses, the system can achieve high ozone production rates during active pulses while allowing cooling and stabilization periods between pulses, reducing overall energy consumption compared to continuous operation at equivalent production levels
3Quantity of substance
If ozone concentration is increased, then less oxygen is required, but more electricity is consumed and heat generation increases
Solution Approach 1:
The patent applies parameter changes by adjusting current pulse amplitude and frequency to optimize the balance between ozone concentration, oxygen consumption, and energy input. The control system can select different parameter combinations depending on whether the priority is minimizing oxygen use, minimizing energy consumption, or achieving a specific ozone concentration, thereby resolving the trade-offs between these parameters
4Adaptability or versatility
If fixed control parameters are used for ozone generation, then device complexity is reduced, but adaptability to varying operating conditions deteriorates
Solution Approach 1:
The patent implements feedback control by continuously monitoring ozone concentration levels and energy consumption, then using this information to adjust current pulse amplitude and frequency. The control system compares actual performance against target values and automatically modifies operating parameters to maintain optimal ozone yield while minimizing energy consumption across varying capacity levels
Solution Approach 2:
The control system performs self-adjustment based on sensor feedback without requiring manual intervention or complex external control mechanisms. The system autonomously monitors its own performance and modifies parameters to optimize efficiency, reducing the need for additional complex control hardware or manual operation
