Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional air purification methods are used, then air purification is provided, but the purification speed is slow and cannot achieve complete purification within 5 minutes
Solution Approach 1:
The air guiding fan operates in multiple modes (normal mode and purification mode) with dynamically adjustable airflow rates. The controller switches between modes based on real-time air quality detection, enabling the system to rapidly increase purification speed when pollution is detected while maintaining energy efficiency during normal conditions.
Solution Approach 2:
The air quality detector continuously monitors indoor air quality and provides real-time feedback to the controller. This feedback loop enables the system to automatically adjust the air guiding fan's operation, ensuring rapid response to pollution events and achieving complete purification within the target time frame.
2Productivity
If high airflow rate is used to increase purification speed, then purification efficiency is improved, but energy consumption increases
Solution Approach 1:
The air guiding fan operates in multiple modes (normal mode and purification mode) with dynamically adjustable airflow rates. The controller switches between modes based on real-time air quality detection, enabling the system to rapidly increase purification speed when pollution is detected while maintaining energy efficiency during normal conditions.
Solution Approach 2:
The system periodically monitors air quality and activates high-speed purification only when necessary. This periodic action pattern allows the system to maintain low energy consumption during normal operation while providing high-performance purification during pollution events, achieving the desired CADR of over 600 m3/h only when required.
3Measurement precision
If real-time monitoring and intelligent control are implemented, then air quality detection accuracy is improved, but device complexity increases
Solution Approach 1:
The networking controller performs multiple functions: it controls the air guiding fan operation, receives air quality data from detectors, determines purification mode activation, and communicates with mobile devices. This multi-functionality reduces the need for separate dedicated components, thereby managing system complexity while achieving real-time monitoring and intelligent control.
Solution Approach 2:
The system automatically monitors air quality, determines when purification is needed, and adjusts fan operation without user intervention. The networking controller self-manages the purification process based on sensor inputs, reducing the need for complex user interfaces and manual control mechanisms.
