Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional preset parameters and static schedules are used for air quality management, then system operation is simple, but the system cannot dynamically adjust to real-time condition changes
Solution Approach 1:
The system transitions from static schedules to dynamic control by continuously monitoring real-time air quality data from multiple sensors and adjusting ventilation parameters accordingly. The machine learning model enables the system to adapt to changing conditions automatically, making the ventilation strategy dynamic rather than fixed.
Solution Approach 2:
The system implements closed-loop feedback control by continuously measuring air quality parameters (PM2.5, PM10, CO2, VOCs, temperature, humidity) and using this feedback to adjust ventilation rates and damper positions. The machine learning model processes this feedback along with forecast data to optimize control decisions in real-time.
2Measurement precision
If comprehensive data fusion from multiple sources is implemented, then air quality management accuracy is improved, but data processing complexity increases
Solution Approach 1:
The machine learning model serves multiple functions simultaneously: it processes real-time sensor data, integrates forecast data from multiple sources (air quality, weather, traffic), predicts future air quality conditions, and generates optimized control strategies. This multi-functionality consolidates what would otherwise require separate systems into a single unified platform.
Solution Approach 2:
The machine learning model acts as an intermediary layer between the diverse data sources (sensors, forecasts, weather data) and the control system. It harmonizes and integrates these heterogeneous data streams, transforming them into actionable control decisions without requiring complex point-to-point integration between each data source and control actuator.
3Object-affected harmful factors
If outdoor air exchange rate is increased to remove indoor contamination, then indoor air quality is improved, but energy consumption increases
Solution Approach 1:
The system dynamically changes ventilation parameters (outdoor air fraction, air exchange rate) based on real-time air quality conditions and predictions. Instead of maintaining constant high ventilation rates, the system adjusts parameters optimally - increasing outdoor air intake when air quality is good and reducing it when pollution is high, thereby balancing indoor air quality with energy efficiency.
Solution Approach 2:
The ventilation strategy transitions from static to dynamic control, where the outdoor air fraction and air exchange rate are continuously adjusted based on real-time sensor data and machine learning predictions. This dynamic adjustment allows the system to maintain effective contamination removal while minimizing energy consumption during periods when high ventilation is not necessary.
4Productivity
If real-time sensor data and forecast data are integrated, then predictive air quality management is achieved, but computational requirements increase
Solution Approach 1:
The system performs preliminary actions by using machine learning models to predict future air quality conditions before they occur. This allows proactive adjustment of ventilation settings in advance of predicted pollution events, improving air quality management efficiency by preventing contamination buildup rather than reacting to it after the fact.
