Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the solvent separating device is continuously operated in separating state, then solvent removal efficiency is improved, but energy consumption increases and the device cannot be quickly switched to idle state
Solution Approach 1:
The solvent separating device is designed to dynamically switch between separating state and idle state based on operational requirements. The switching mechanism allows the device to adapt its separating capacity, enabling quick transition from active solvent removal to standby mode, thereby reducing energy consumption when continuous separation is not needed while maintaining high removal efficiency when required.
2Use of energy by moving object
If the solvent separating device is switched off completely in idle state, then energy consumption is reduced, but the time to restore separating capacity increases
Solution Approach 1:
The device maintains a standby state with residual separating capacity instead of complete shutdown. This preliminary maintenance of partial functionality allows the device to quickly resume full separating operation when needed, avoiding the time required to rebuild separating capacity from zero while still reducing energy consumption compared to continuous operation.
3Reliability
If the solvent separating device operates at full capacity continuously, then solvent separation performance is improved, but the complexity of operation and control increases
Solution Approach 1:
The operating states are segmented into distinct modes (separating state and idle state) with clear switching criteria. This segmentation simplifies operation by providing well-defined states rather than continuous adjustment, making the system easier to control while maintaining reliable solvent separation performance when in the separating state.
