Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional air-cooled systems with multiple fans are used, then the server can operate with basic cooling, but the heat dissipation performance is insufficient when server performance is upgraded
Solution Approach 1:
The patent transitions from air-cooled to liquid-cooled system by introducing a liquid cooling apparatus with cooling liquid circulation. The liquid cooling system absorbs heat more efficiently from high-performance server components, resolving the insufficient heat dissipation performance when server performance is upgraded.
Solution Approach 2:
The patent changes the cooling medium parameter from gas (air) to liquid (cooling liquid), which has higher specific heat capacity and thermal conductivity. This parameter change enables the cooling system to handle the increased heat load from upgraded server performance.
2Temperature
If a liquid cooling system is implemented, then heat dissipation efficiency is improved, but device complexity increases due to additional components like pumps and tanks
Solution Approach 1:
The patent divides the cooling system into modular components: a liquid cooling apparatus and a separate removable device. The removable device can be detached and replaced independently, simplifying maintenance and reducing overall system complexity while maintaining effective liquid cooling.
Solution Approach 2:
The patent introduces a sliding mechanism that allows the removable device to move between an operating position (inserted into the chassis) and a removed position (detached for maintenance). This dynamic design enables easy access and replacement of cooling components without disassembling the entire system.
3Stability of the object's composition
If the cooling system components are fixed, then structural stability is maintained, but maintenance and upgrades become difficult
Solution Approach 1:
The patent segments the cooling system into a fixed chassis portion and a removable device portion. The removable device can be easily detached and replaced for maintenance or upgrades, while the fixed chassis maintains structural stability. This segmentation resolves the conflict between structural stability and ease of repair.
Solution Approach 2:
The patent designs the removable device with pre-configured cooling elements and routing that can be quickly installed and removed. The sliding mechanism is pre-designed to guide the removable device into proper position, enabling rapid maintenance without complex assembly procedures.
4Area of stationary object
If tubes are routed through moving components, then cooling coverage is improved, but tube entanglement and damage risk increases
Solution Approach 1:
The patent separates the tube routing into fixed portions (in the chassis) and movable portions (in the removable device). The sliding mechanism includes guides that prevent excessive movement and entanglement of tubes, while still allowing the removable device to move for maintenance. This segmentation reduces tube damage risk while maintaining cooling coverage.

AI summary
An electronic apparatus with a cooling system includes a chassis having a mounting slot, and a removable device. The removable device includes a housing detachably disposed in the mounting slot; a first pump disposed in the housing, and detachably affixed to a bottom of the housing; a second pump detachably affixed to the bottom of the housing, and connected to the first pump; and a tank disposed on the first pump and configured to store cooling liquid. when the first pump or the second pump is operating, the cooling liquid in the tank flows into the first pump, and the cooling liquid in the first pump flows into the second pump.
