Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the electric field is modified to increase disintegration power, then disintegration performance is improved, but the device cannot rapidly adapt to changing fluid properties
Solution Approach 1:
The control unit continuously monitors operating parameters (voltage, current, frequency) and adjusts the electric field parameters in real-time based on the actual state of the fluid mixture, enabling the device to maintain optimal disintegration power despite changes in fluid properties
Solution Approach 2:
The electric field parameters (voltage amplitude, frequency, pulse duration) are made dynamically adjustable through the control unit, allowing the system to transition from static predetermined settings to dynamic real-time optimization based on actual operating conditions
2Ease of operation
If predetermined operating parameters are used for calibration, then device operation is simplified, but the electric field strength cannot be optimized for changing conditions
Solution Approach 1:
The control unit automatically monitors and adjusts the electric field parameters based on real-time measurements of operating parameters, eliminating the need for manual recalibration and maintaining optimal performance without user intervention
3Reliability
If the chamber is grounded for safety, then operator safety is improved, but direct measurement of the electric field inside the chamber becomes difficult
Solution Approach 1:
The control unit serves as an intermediary that indirectly measures the electric field strength by monitoring related operating parameters (voltage, current, frequency) and calculating the field characteristics, avoiding the need for direct measurement devices that would compromise safety
