Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If metal heat sink with air flow heat dissipation is used, then structure is simple, but heat dissipation performance is insufficient for high transmission speed connectors
Solution Approach 1:
The patent replaces the air flow-based mechanical heat dissipation system with a liquid cooling system. Liquid cooling trays with cooling channels are integrated into the connector assembly, allowing coolant to flow through and directly remove heat from the connector components, thereby achieving superior heat dissipation performance for high transmission speed applications.
Solution Approach 2:
The patent employs composite construction by integrating liquid cooling trays made of thermally conductive materials (such as aluminum or copper) with the connector assembly. The cooling trays feature integrated heat dissipation fins and cooling channels, combining thermal conduction and convection mechanisms to enhance overall heat dissipation effectiveness.
2Adaptability or versatility
If fluid pressure-driven pedestals with bellows are used, then flexible connection is achieved, but structure becomes complex and manufacturing becomes difficult
Solution Approach 1:
The patent extracts and eliminates the complex bellows component from the pedestal assembly. Instead of using bellows to achieve flexible connection, the design employs simplified pedestal structures that can be directly mounted to the cooling trays, maintaining adaptability while significantly reducing structural complexity and manufacturing difficulty.
Solution Approach 2:
The patent segments the cooling system into modular components including separate cooling trays, pedestals, and mounting structures. This segmentation allows each component to be independently manufactured and assembled, simplifying the overall structure while maintaining flexible connection capabilities through standardized interfaces.
3Adaptability or versatility
If fluid pressure-driven pedestals are used, then flexible connection is achieved, but contact consistency with electrical modules deteriorates due to insufficient or unstable fluid pressure
Solution Approach 1:
The patent implements self-adjusting pedestal structures that automatically maintain consistent contact pressure with electrical modules. The pedestals are designed with elastic or spring-loaded mechanisms that compensate for pressure variations, ensuring reliable contact without requiring stable external fluid pressure, thereby improving contact consistency while maintaining flexible connection capabilities.
4Adaptability or versatility
If multiple electrical modules need to contact individual pedestals simultaneously, then connection capacity increases, but contact reliability decreases due to tolerance variations and insufficient protruding amount
Solution Approach 1:
The patent employs dynamically adjustable pedestal structures that can independently adapt to the position and tolerance variations of multiple electrical modules. Each pedestal is designed with movable or elastic characteristics, allowing it to self-adjust and maintain optimal contact pressure despite variations in module positioning, thereby ensuring reliable contact across multiple connection points simultaneously.
