Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If real-time monitoring of filtrate is implemented in batch-type filtering apparatus, then measurement precision and operational control are improved, but device complexity increases due to additional flow paths, valves, and sensing components
Solution Approach 1:
The system divides filtrate flow into multiple segments using separate flow paths (first flow path for monitoring, second flow path for collection). This allows real-time optical sensing of filtrate characteristics without mixing monitoring and collection functions, enabling precise measurement while maintaining manageable system complexity through functional separation.
Solution Approach 2:
A flow cell is introduced as an intermediary component between the filtration system and the optical detector. The flow cell provides a controlled environment for light interaction with filtrate, enabling real-time monitoring of filtrate properties (such as clarity, concentration, or presence of particles) without directly complicating the main filtration structure.
2Adaptability or versatility
If multiple flow paths and direction switching valves are added to enable real-time sensing, then adaptability and operational flexibility are improved, but device complexity increases
Solution Approach 1:
Direction switching valves are implemented to dynamically reconfigure flow paths during operation. The system can switch between different flow path configurations (e.g., directing filtrate to monitoring, collection, or both simultaneously) based on operational requirements. This dynamic adaptability allows a single system to perform multiple functions without requiring separate fixed systems for each function.
Solution Approach 2:
The flow paths and valves are designed to serve multiple functions: the first flow path handles both monitoring and collection at different times, the second flow path can receive filtrate from different sources, and external ports enable various connection configurations. This multi-functionality reduces the need for separate dedicated systems for each operation mode.
3Measurement precision
If filtrate is directed through the flow cell for optical sensing, then measurement capability is improved, but loss of time occurs during flow path switching
Solution Approach 1:
The system pre-configures multiple flow paths and valves in advance, allowing rapid switching between monitoring and collection modes without complex real-time calculations or adjustments. The direction switching valves are positioned and sized to minimize flow disruption during transitions, and the flow cell is pre-positioned to receive filtrate immediately when monitoring mode is activated, reducing switching delays.
