Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional wiring methods are used to connect servers to the cabinet, then electrical connections can be established, but the assembly process becomes time-consuming and labor-intensive
Solution Approach 1:
The electrical connection system is segmented into modular components: a conductive plate fixed in the cabinet, removable servers with integrated power input ports, and corresponding connectors. This segmentation allows servers to be independently assembled and connected without requiring complex wiring operations, thus reducing assembly time while maintaining reliable electrical connections.
Solution Approach 2:
The conductive plate is pre-fixed in the cabinet before server assembly. The power input ports and connectors are pre-configured on the servers and in the cabinet respectively. This preliminary preparation eliminates the need for on-site wiring operations, significantly reducing assembly time while ensuring reliable electrical connections are established automatically when servers are inserted.
2Reliability
If manual wiring is performed for each server, then electrical connections are established, but the process becomes inconvenient and labor-intensive
Solution Approach 1:
The power input port and connector are merged into an integrated connection system where the server's power input port directly interfaces with the cabinet's connector through the conductive plate. This merging eliminates the need for separate wiring operations, making assembly convenient while ensuring reliable electrical connections are automatically established.
Solution Approach 2:
The server assembly process becomes self-service oriented: when a server is inserted into the cabinet, its power input port automatically connects to the conductive plate and connector without requiring manual wiring operations. The system performs the electrical connection automatically based on the physical insertion, improving ease of operation while maintaining connection reliability.
3Reliability
If servers are connected using traditional wiring methods, then electrical connectivity is achieved, but positioning precision and connectivity reliability are compromised
Solution Approach 1:
The conductive plate provides a uniform electrical connection surface that is equipotential across the cabinet. All servers connect to this common reference plane through standardized interfaces, ensuring consistent electrical connectivity and positioning precision regardless of which server is installed in which position, thereby improving both reliability and positioning accuracy.

AI summary
A rack server system includes a container, an electrically conductive component, a power supply, a signal connecting base, a server, and an RMC. The electrically conductive component and the signal connecting base are fixed in the container. The power supply is electrically connected to the electrically conductive component for supplying a direct current power. The signal connecting base includes multiple connectors. The server, disposed in the container removably, includes a power input port and a connecting element. The power input port is electrically connected to the electrically conductive component removably. The connecting element is connected to the connector removably. When the connecting element is electrically connected to the connector, the RMC communicates with the server via the connecting element and the one of the connectors and determines the position of the server in the container according to another position of the connector which is electrically connected to the server.
