Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the heat exchanger is integrated with the dialysis machine in a common housing, then the system structure is compact and simple, but the system flexibility and adaptability to different application scenarios are reduced
Solution Approach 1:
The patent divides the integrated system into separate modular components: the dialysis machine and the heat exchanger are configured as independent devices that can be connected or disconnected. This segmentation allows each component to be optimized independently while maintaining system functionality, thereby improving adaptability to different application scenarios without significantly increasing overall system complexity.
Solution Approach 2:
The heat exchanger is designed as a universal component that can be used with multiple different dialysis machines and adapted to various application scenarios. By making the heat exchanger independent and interchangeable, the system gains versatility to accommodate different dialysis requirements while keeping the overall structure relatively simple through standardized connections.
2Adaptability or versatility
If the heat exchanger is configured as a separate device, then the system flexibility and adaptability are improved, but the device complexity and connection requirements increase
Solution Approach 1:
The system incorporates dynamic connection capabilities where the heat exchanger can be easily connected to or disconnected from the dialysis machine without permanent modification. This dynamic configuration allows the system to adapt to different operational requirements while managing connection complexity through standardized, reversible interfaces that simplify the connection process.
3Volume of stationary object
If the heat exchanger is integrated with the dialysis machine, then the system is compact, but heat loss efficiency and waste heat utilization are reduced
Solution Approach 1:
The heat exchanger is extracted from the integrated configuration and positioned as a separate device with optimized heat exchange capabilities. This extraction allows for larger, more efficient heat exchange surfaces and better thermal management without compromising system compactness, as the heat exchanger can be strategically positioned to maximize waste heat recovery from dialysate to preheat permeate.
