Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple card connectors are used to transmit power supply and signal separately, then the transmission function is reliable, but the space occupation and mounting cost increase
Solution Approach 1:
The patent combines power supply terminals and signal terminals into a single card connector assembly. The connector includes a first card connector for power supply transmission and a second card connector for signal transmission, both integrated into one unified structure that occupies a single mounting position on the circuit board, thereby reducing space requirements while maintaining separate transmission functions.
Solution Approach 2:
The integrated card connector serves multiple functions simultaneously: it provides both power supply transmission through the first card connector and signal transmission through the second card connector. This multi-functional design allows a single connector assembly to replace what would traditionally require multiple separate connectors, reducing both space occupation and mounting complexity.
2Reliability
If multiple card connectors are installed to transmit power and signal, then the transmission capability is sufficient, but the mounting difficulty and cost increase
Solution Approach 1:
The patent integrates multiple connector functions into a single mounting position. The first card connector and second card connector are assembled together as one unit and mounted simultaneously to the circuit board, reducing the number of separate mounting operations required and simplifying the installation process while maintaining adequate transmission capability for both power and signal.
3Speed
If the connector structure is adjusted or additional connectors are added to upgrade server speed from 8G to 16G or 25G, then the signal transmission speed can be improved, but the structural complexity and cost increase
Solution Approach 1:
The patent employs detachable and pluggable terminal designs that allow for easy reconfiguration and upgrading. The terminals can be removed and replaced without altering the overall connector structure, enabling smooth transitions from 8G to 16G or 25G signal speeds by simply replacing terminal components rather than redesigning the entire connector assembly.
Solution Approach 2:
The connector is designed with separable components including detachable terminals and modular structures. This segmentation allows specific parts to be upgraded independently to support higher signal speeds while maintaining the core connector structure, thereby reducing the complexity associated with full structural redesigns for speed upgrades.
