Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If advanced manufacturing processes are used to improve sealing reliability, then leakage rate is reduced, but system cost increases and design flexibility is limited
Solution Approach 1:
The invention extracts the pressure regulation function from the sealing system by introducing a separate shrinking bag component. This allows the sealing structure to remain simple while adding pressure relief capability, avoiding the need for complex sealed structures and reducing manufacturing costs.
Solution Approach 2:
The shrinking bag acts as an intermediary component between the sealed system and the external environment. It provides a controlled interface for pressure regulation without compromising the sealing integrity, allowing pressure relief while maintaining reliable seals at all connection points.
2Reliability
If sealing structures are enhanced to prevent leakage, then system reliability improves, but device complexity increases
Solution Approach 1:
The invention separates the pressure regulation function from the sealing structure by introducing an independent shrinking bag component. This allows simple sealing connections while adding intelligent pressure control, reducing overall system complexity.
Solution Approach 2:
The shrinking bag provides self-regulating pressure control through its automatic shrinking response to pressure changes. This eliminates the need for complex control systems, sensors, or actuators, maintaining simplicity while ensuring reliable leakage prevention.
3Temperature
If the system operates in high-temperature environment for extended periods, then cooling performance is maintained, but internal pressure increases causing leakage risk
Solution Approach 1:
The shrinking bag provides dynamic pressure regulation that automatically adapts to changing operating conditions. As temperature and pressure increase during high-temperature operation, the bag shrinks to provide expansion space, preventing leakage without affecting cooling performance.
Solution Approach 2:
The invention changes the volume parameter of the cooling system dynamically through the shrinking bag's pressure-responsive deformation. This allows the system to accommodate thermal expansion and pressure increases during high-temperature operation while maintaining sealing integrity.
4Strength
If sealing components are strengthened to resist internal pressure, then pressure resistance improves, but component fatigue increases over time
Solution Approach 1:
The invention removes the requirement for high-pressure resistance from sealing components by providing pressure relief through the shrinking bag. Sealing components only need to handle normal operating pressures, dramatically reducing fatigue and extending service life.
Solution Approach 2:
The shrinking bag provides beforehand cushioning by creating expansion space before pressure reaches critical levels. This prevents extreme pressure spikes that would cause fatigue and failure of sealing components, allowing them to operate within safe stress limits continuously.

Function Achieved in This Case
The solution effectively reduces the risk of leakage by dynamically adjusting the internal volume of the coolant system, maintaining system appearance and size, and minimizing maintenance and cost.
Implementation Method 1
when the internal pressure of the computer is too high, the coolant squeezes the shrinking bag to expand the internal volume of the coolant, so that the increased pressure is released
