Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous adsorbent regeneration is performed to ensure moisture removal capacity, then reliability of moisture removal is improved, but energy consumption increases
Solution Approach 1:
The patent implements dynamic adjustment of regeneration timing and duration based on real-time moisture load rate calculations. The controller monitors accumulated moisture removal amounts and adjusts the regeneration process dynamically, switching between dehumidification and regeneration modes based on calculated moisture load rates, thereby optimizing energy usage while maintaining reliable moisture removal.
Solution Approach 2:
The system changes operational parameters (process time, regeneration intensity) based on calculated moisture load rates. By adjusting the timing and duration of regeneration processes according to actual moisture accumulation levels rather than operating on fixed schedules, the system reduces unnecessary energy consumption while ensuring moisture removal reliability is maintained.
2Quantity of substance
If process time for dehumidification is extended to remove more moisture, then moisture removal amount is improved, but energy consumption increases
Solution Approach 1:
The controller continuously calculates moisture load rates based on accumulated moisture removal amounts and uses this feedback to adjust process timing. The system monitors the moisture removal capacity in real-time and adjusts the dehumidification and regeneration process durations accordingly, extending process time only when necessary to meet moisture removal requirements without excessive energy consumption.
3Productivity
If frequent regeneration is performed to maintain adsorbent capacity, then dehumidification efficiency is improved, but productivity is reduced due to process interruptions
Solution Approach 1:
The system dynamically determines regeneration timing based on calculated moisture load rates rather than following fixed regeneration schedules. By monitoring accumulated moisture removal amounts in real-time, the controller extends dehumidification processes when moisture load rates indicate capacity remains sufficient, thereby reducing unnecessary regeneration interruptions and improving overall productivity.
