Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If straight copper tubes are used to connect water blocks, then leakage problems are solved, but thermal deformation occurs during welding causing tolerance issues and increased manufacturing cost
Solution Approach 1:
The connection tube changes its physical state from rigid to flexible through the bellows structure, allowing it to accommodate thermal deformation without compromising the welding tolerance of the water blocks. This parameter change enables the system to maintain both reliability and manufacturing precision.
Solution Approach 2:
The bellows section of the connection tube acts as a flexible element that can expand and contract to absorb thermal deformation. This flexible structure allows the rigid copper tube to accommodate welding-induced dimensional changes while maintaining leak-free connections.
2Manufacturing precision
If precise welding tools and skilled operators are employed to reduce thermal deformation, then welding quality improves, but production time increases and cost increases
Solution Approach 1:
By changing the rigidity parameter of the connection tube through the bellows design, the system tolerates thermal deformation without requiring high-precision welding, thereby maintaining productivity and reducing costs while ensuring connection reliability.
3Stability of the object's composition
If straight copper tubes are used for connection, then structural stability is achieved, but elasticity is insufficient to eliminate tolerance differences between chips and perforations
Solution Approach 1:
The bellows section provides the necessary flexibility and elasticity to accommodate tolerance differences between chips and perforations, while the overall rigid structure of the copper tube maintains structural stability for effective heat dissipation.
Solution Approach 2:
The connection tube is segmented into rigid sections (for structural stability) and a flexible bellows section (for tolerance accommodation), allowing it to simultaneously provide both stability and adaptability in the water-cooling system.
4Ease of operation
If rubber water hoses are used to connect water blocks, then assembly flexibility is improved, but detachment and oxidation occur causing leakage
Solution Approach 1:
The connection tube combines the advantages of rigid metal tubes (leak-proof, oxidation-resistant) with the flexibility of bellows structures (assembly flexibility), creating a composite solution that eliminates the drawbacks of both rubber hoses and straight copper tubes.

AI summary
A liquid-cooling device includes multiple water blocks and at least one connection tube. Each of the water blocks has a water incoming end, a water outgoing end and a water-receiving space in communication with the water incoming end and the water outgoing end. The connection tube is disposed between each two water blocks. Two ends of the connection tube are respectively connected with the water incoming end of one of the two water blocks and the water outgoing end of the other water block, whereby the water-receiving spaces of the two water blocks communicate with each other via the connection tube. The connection tube has at least one bellows section between two ends of the connection tube. The liquid-cooling device solves the problems of the conventional liquid-cooling device that when the water block is welded, thermal deformation is produced to cause tolerance and the manufacturing cost is higher.
