Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a high exhaust air volume is used to dry container units, then the drying effectiveness is improved, but the energy consumption increases significantly
Solution Approach 1:
The exhaust air volume is made dynamically adjustable rather than fixed. The control device modifies the exhaust air volume based on real-time parameters such as solvent input, can density, and production rate, allowing the system to optimize between drying effectiveness and energy consumption for different operating conditions
Solution Approach 2:
The system changes the exhaust air volume parameter dynamically based on measured process conditions. By monitoring solvent input, can density, and production rate, the control device adjusts the exhaust air volume to maintain optimal drying while minimizing energy waste
2Use of energy by stationary object
If the exhaust air volume is reduced to save energy, then energy consumption decreases, but the drying effectiveness and safety are compromised
Solution Approach 1:
The system implements feedback control by continuously measuring process parameters (solvent input, can density, production rate) and using this information to adjust the exhaust air volume. This ensures that the exhaust air volume is always sufficient for safety and drying effectiveness while minimizing energy consumption
Solution Approach 2:
The system performs preliminary measurements of solvent input, can density, and production rate before adjusting the exhaust air volume. This allows the control device to proactively set the appropriate exhaust air volume to ensure drying effectiveness and safety before the actual drying process begins
3Reliability
If a fixed minimum exhaust air volume is maintained, then safety is ensured, but energy efficiency is reduced
Solution Approach 1:
The system transitions from a fixed minimum exhaust air volume to a dynamically adjusted exhaust air volume that adapts to real-time production conditions. The control device ensures safety by maintaining adequate exhaust air volume while optimizing energy efficiency by reducing it when production conditions allow
