Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a sealed space is formed inside the water cooling plate for cooling liquid circulation, then heat dissipation efficiency is improved, but pressure buildup occurs leading to potential damage or liquid leakage
Solution Approach 1:
A pressure balancing bag is introduced as an intermediary component between the sealed water cooling chamber and the external environment. The bag expands and contracts to absorb pressure fluctuations, acting as a mediator that prevents direct transmission of pressure spikes to the sealed chamber walls and sealing interfaces, thereby maintaining system reliability while preserving heat dissipation efficiency.
Solution Approach 2:
The system dynamically changes the volume parameter of the pressure balancing bag in response to pressure variations. When pressure increases, the bag expands to accommodate excess pressure; when pressure decreases, the bag contracts. This dynamic parameter adjustment allows the sealed chamber to maintain stable operating conditions without compromising its sealed nature or heat dissipation performance.
2Reliability
If the sealing is made stronger to prevent leakage, then liquid tightness is improved, but pressure balance capability deteriorates due to inability to release excessive pressure
Solution Approach 1:
The pressure balancing bag serves as a buffer intermediary between the sealed chamber and the external atmosphere. It allows the sealing to remain strong and tight while providing a compliant element that can expand and contract to accommodate pressure changes, thus decoupling the sealing function from the pressure regulation function.
Solution Approach 2:
The pressure balancing bag provides beforehand cushioning by being pre-installed in the system to absorb and mitigate pressure spikes before they can cause damage or force liquid through seals. This preventive measure cushions the sealed chamber against pressure-related failures while maintaining sealing integrity.
3Strength
If the water cooling plate is made more durable to withstand high pressure, then structural strength is improved, but the system becomes more prone to pressure buildup issues
Solution Approach 1:
The pressure balancing bag acts as a pressure-regulating intermediary that works in conjunction with the durable water cooling plate. The bag's compliance provides a pressure relief mechanism that complements the structural strength of the plate, creating a synergistic system where the plate's durability and the bag's pressure regulation work together to prevent pressure-related failures.
Solution Approach 2:
The system transitions from a static, rigid pressure containment structure to a dynamic system where the pressure balancing bag can expand and contract. This dynamic behavior allows the system to adapt to changing pressure conditions, maintaining structural integrity through active pressure management rather than relying solely on increased material strength.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The pressure bag effectively balances pressure inside the water cooling plate, preventing damage and leakage, while the water pump and integrated circuit board enhance the system's efficiency and ease of maintenance, ensuring reliable heat dissipation and user convenience.
Implementation Method 1
when a pressure inside the water chamber becomes greater, the air inside the pressure bag is compressed to balance the pressure inside the water chamber
Implementation Method 2
the sealing plug has provided thereon a weak part, and when a pressure inside the sealed chamber is excessive, the weak part breaks, so that the air inside the pressure bag is partially leaked out
Implementation Method 3
a water pump is disposed at a water outlet nozzle of the water cooling plate; cooling water inside the water cooling plate is pumped, through the water pump, into the water block to absorb heat
Implementation Method 4
cooling water inside the water cooling plate is pumped, through the water pump, into the water block to absorb heat
