Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cycle-based control is used to repeat energization and non-energization cycles, then the device can operate continuously, but the hypochlorous acid water concentration does not necessarily reach the target concentration
Solution Approach 1:
The patent changes the control parameter from fixed cycle-based timing to dynamically calculated energization time based on required concentration. The control unit calculates the necessary energization time to achieve the target hypochlorous acid concentration, allowing precise concentration control while maintaining operational reliability.
Solution Approach 2:
The patent implements feedback control by measuring the actual hypochlorous acid concentration and using this information to adjust the energization time. The control unit compares the measured concentration with the target concentration and modifies the energization duration accordingly, ensuring the target concentration is reliably achieved.
2Ease of operation
If fixed energization and non-energization cycle times are used, then the control process is simple, but the hypochlorous acid water concentration varies and may not reach the target
Solution Approach 1:
The patent maintains ease of operation by automating the calculation process, where the control unit automatically determines the optimal energization time based on desired concentration parameters. This eliminates complex manual adjustments while achieving precise concentration control through dynamic parameter adaptation.
Solution Approach 2:
The control unit performs self-adjustment by automatically calculating and modifying the energization time based on concentration measurements. The system serves itself by using its own measurement data to optimize its operation, maintaining simplicity while improving precision without requiring external intervention.
3Manufacturing precision
If energization time is extended to ensure target concentration is reached, then concentration accuracy improves, but energy consumption increases
Solution Approach 1:
The patent uses feedback control to minimize energy consumption while achieving target concentration. The control unit measures the actual concentration and terminates energization as soon as the target is reached, avoiding unnecessary extended energization periods that would waste energy while maintaining concentration accuracy.
Solution Approach 2:
The patent dynamically adjusts the energization time parameter based on real-time concentration measurements and system conditions. By calculating the minimum required energization time to reach the target concentration, the system optimizes energy usage while ensuring concentration accuracy, adapting the parameter to actual needs rather than using fixed extended periods.
