Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the pressure in the containing space is increased to improve heat dissipation efficiency, then the heat dissipation performance is improved, but the gaseous heat dissipation medium easily escapes to the outside environment
Solution Approach 1:
The patent converts the harmful effect of high pressure (causing medium escape) into a beneficial feature by introducing a pressure-adjusting module that creates negative pressure. This negative pressure state prevents the gaseous heat dissipation medium from escaping while maintaining effective heat dissipation, thus transforming the original problem into a solution.
Solution Approach 2:
The patent changes the pressure parameter from positive/high pressure to negative pressure by using the pressure-adjusting module. This parameter change fundamentally alters the system's behavior, preventing medium escape while maintaining heat dissipation efficiency through the negative pressure differential.
2Productivity
If the pressure in the containing space is high, then the heat dissipation performance is improved, but the maintenance cost increases due to medium loss
Solution Approach 1:
The patent transforms the high-pressure condition that causes medium loss and increased maintenance costs into a negative pressure system. This conversion eliminates medium escape, thereby reducing maintenance costs while preserving heat dissipation performance.
Solution Approach 2:
The pressure-adjusting module automatically maintains the negative pressure state in the containing space, preventing medium escape without requiring manual intervention or frequent maintenance. The system self-regulates the pressure condition to prevent loss.
3Temperature
If the pressure in the containing space is increased to enhance cooling efficiency, then the cooling performance is improved, but the system reliability decreases due to medium escape
Solution Approach 1:
The patent changes the pressure parameter from positive to negative using the pressure-adjusting module. This parameter change ensures that the gaseous heat dissipation medium remains contained within the system, improving reliability while maintaining cooling efficiency through the negative pressure differential.
Solution Approach 2:
The patent converts the harmful high-pressure condition that compromises reliability into a beneficial negative pressure state. This transformation prevents medium escape and potential system failures, thereby enhancing reliability while preserving cooling performance.
