Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If threshold control method is used to activate ventilation apparatus only when pollutant exceeds threshold, then energy consumption is reduced, but air quality oscillation occurs and ventilation may be insufficient
Solution Approach 1:
The patent implements dynamic adjustment of ventilation parameters by continuously monitoring pollutant concentrations and automatically modifying ventilation rate, activation conditions, and operational timing. This dynamic control prevents air quality oscillation while maintaining energy efficiency, resolving the contradiction between reduced energy consumption and stable air quality.
Solution Approach 2:
The system incorporates real-time feedback mechanisms where pollutant sensor data continuously informs ventilation control decisions. The controller adjusts ventilation parameters based on feedback from air quality measurements, ensuring stable air quality maintenance while optimizing energy consumption through responsive rather than reactive control.
2Quantity of substance
If scheduling control method activates ventilation at fixed time, then air ventilation volume target is achieved, but air quality deteriorates when occupancy changes suddenly
Solution Approach 1:
The patent transitions from fixed scheduling to dynamic ventilation control that automatically adjusts ventilation rate and timing based on real-time occupancy detection and air quality monitoring. This enables the system to maintain appropriate ventilation volume targets while adapting to sudden occupancy changes.
Solution Approach 2:
The system dynamically changes ventilation parameters including activation conditions, operational timing, and ventilation rate based on monitored environmental conditions and occupancy levels. This parameter adaptation ensures both sufficient ventilation volume and responsiveness to occupancy changes.
3Reliability
If threshold is set low to ensure adequate ventilation, then air quality is maintained, but energy consumption increases due to hyperventilation
Solution Approach 1:
The patent implements partial ventilation action by adjusting ventilation rate to match actual air quality needs rather than maintaining constant high ventilation. The system applies ventilation only to the extent necessary to maintain air quality standards, avoiding the energy waste of hyperventilation while ensuring adequate air quality maintenance.
Solution Approach 2:
The system dynamically changes the effective threshold for ventilation activation based on real-time conditions, allowing higher thresholds when air quality is good and lowering them when pollutants increase. This parameter adaptation maintains air quality while minimizing unnecessary ventilation and energy consumption.
