Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If microwave power is increased to speed up drying, then drying speed is improved, but thermal damage to the dialysis filter increases
Solution Approach 1:
The microwave generating unit dynamically adjusts its power output during the drying process. The control unit receives feedback from moisture sensors and automatically modulates the microwave power to match the current moisture content of the filter, enabling high power when wet and reduced power as the filter dries, thus preventing thermal damage while maintaining fast drying speed
Solution Approach 2:
The system incorporates moisture sensors that continuously monitor the moisture content of the dialysis filter during drying. This feedback information is fed to the control unit, which adjusts the microwave generating unit's power accordingly, creating a closed-loop control system that adapts to the drying progress and prevents overheating
2Productivity
If constant high power microwaves are used, then drying speed is improved, but energy waste increases due to heating of non-moisture parts
Solution Approach 1:
The system applies microwave energy at the minimum necessary level at each stage of drying. By using moisture sensors to detect the current moisture content and adjusting power accordingly, the system avoids applying excessive energy that would heat non-moisture parts, thereby reducing energy waste while maintaining effective drying speed
Solution Approach 2:
The control unit changes the power parameter of the microwave generating unit based on real-time moisture content measurements. As the filter dries and moisture content decreases, the system automatically reduces microwave power, ensuring energy is only applied when and where needed, thus minimizing energy waste
