Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible pipe with loop shape is used to connect the evaporator and cooling tower, then the evaporator can be moved and the system becomes more flexible, but refrigerant stagnation occurs at reverse inclination portions and cooling efficiency is degraded
Solution Approach 1:
The system employs a dynamic support structure that allows the flexible pipe to maintain optimal inclination angles while accommodating evaporator movement. The support mechanism adapts the pipe's position to prevent reverse inclinations that cause refrigerant stagnation, thus maintaining cooling efficiency while preserving positioning flexibility.
Solution Approach 2:
The invention changes the inclination angle parameter of the flexible pipe by providing support structures at specific intervals. By controlling the pipe's inclination to be always forward (no reverse inclination), the system optimizes refrigerant flow while maintaining the flexibility needed for evaporator repositioning.
2Productivity
If the cooling tower is placed higher than the evaporator, then refrigerant vapor and liquid can be conveyed effectively using gravity, but the flexible pipe must have complex routing to accommodate the height difference and movement requirements
Solution Approach 1:
The invention uses a flexible pipe that can bend and adapt its shape to connect the evaporator and cooling tower with a simple routing. The flexibility of the pipe allows it to accommodate height differences and evaporator movement without requiring complex rigid routing structures, reducing overall system complexity while maintaining effective refrigerant flow.
3Ease of operation
If the flexible pipe is allowed to move freely to accommodate evaporator repositioning, then the evaporator can be easily moved, but reverse inclinations in the pipe cause refrigerant stagnation and reduced cooling performance
Solution Approach 1:
The support structure provides dynamic adjustment capability, allowing the flexible pipe to maintain optimal inclination angles during evaporator repositioning operations. This ensures that the pipe adapts to new positions while preventing reverse inclinations that would cause refrigerant stagnation, thus maintaining cooling performance during and after repositioning.
