Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual air valve adjustment is used to control air supply and exhaust, then the system can operate with simple structure, but the air volume cannot be timely and effectively controlled according to actual drying requirements
Solution Approach 1:
The system uses automatic control to regulate air supply and exhaust volumes based on real-time sensor feedback, eliminating the need for manual adjustment while maintaining operational simplicity. The controller automatically balances air pressure and flow rates across multiple drying units.
2Reliability
If excess air volume is discharged to ensure safety, then safety accidents are prevented, but energy waste and air pollution increase
Solution Approach 1:
The system incorporates sensors that continuously monitor air pressure, temperature, and flow rates, providing feedback to the controller. The controller adjusts air supply and exhaust volumes in real-time to maintain safe operating conditions while minimizing energy waste by discharging only the necessary excess air volume.
Solution Approach 2:
The system dynamically adjusts air flow parameters and pressure differentials based on actual drying requirements and safety conditions. By optimizing these parameters, the system maintains safety margins without consistently discharging excessive air volumes, thereby reducing heating energy waste.
3Ease of operation
If multiple air valves are adjusted manually to balance air pressure difference, then air flow can be distributed to various units, but the adjustment requires high operator skill and is difficult to perform timely
Solution Approach 1:
The system automatically balances air pressure differences across multiple drying units using controlled air supply and exhaust valves. The controller receives feedback from pressure sensors and adjusts valve positions accordingly, eliminating the need for skilled manual adjustment while maintaining proper air flow distribution.
4Object-affected harmful factors
If centralized air supply with dust removal and humidity control is implemented, then air quality is improved, but air pressure difference balancing becomes more complex requiring multiple valve adjustments
Solution Approach 1:
The system uses pressure sensors and controllers to automatically monitor and balance air pressure differences across multiple drying units after centralized air supply. This feedback mechanism simplifies the operation by eliminating manual valve adjustments while maintaining proper pressure balance throughout the system.
