Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual electrical connections are made between each server and the cabinet, then precise electrical connection is achieved, but assembly time increases significantly
Solution Approach 1:
The electrical connection system is segmented into modular components: power input ports on each server, corresponding electrically conductive components in the cabinet, signal connecting bases with multiple connectors, and rack management controllers. This segmentation allows servers to be independently connected through standardized interfaces rather than requiring manual wiring of each connection point.
Solution Approach 2:
The cabinet is pre-configured with electrically conductive components, power supplies, signal connecting bases with multiple connectors, and rack management controllers before servers are installed. The guiding pins and connector positions are predetermined, so when servers are placed in the cabinet, electrical connections are automatically established without requiring manual assembly of each connection.
2Area of stationary object
If multiple servers are disposed in the same cabinet, then space utilization improves, but complexity of electrical connections increases
Solution Approach 1:
The signal connecting base provides universal multi-functionality by incorporating multiple connectors that can interface with different server types and configurations. The rack management controller serves multiple servers simultaneously through a single interface structure, eliminating the need for separate complex wiring for each server while maintaining individualized control and communication capabilities.
Solution Approach 2:
The signal connecting base acts as an intermediary between the cabinet's power supply and control systems and the multiple servers. Instead of direct complex connections between each server and the cabinet's internal systems, the signal connecting base with its multiple connectors mediates these connections, simplifying the overall electrical architecture while supporting multiple servers.
3Ease of operation
If servers are made removable from the cabinet, then flexibility and ease of maintenance improve, but risk of electrical misconnection increases
Solution Approach 1:
The electrical connection interfaces utilize asymmetric designing where the power input ports and connecting elements on servers have specific geometries that only match corresponding receptacles in the cabinet at the correct orientation and position. This asymmetric design ensures that servers can only be connected in the proper configuration, preventing misconnection while maintaining ease of installation and removal.
Solution Approach 2:
The patent replaces complex manual mechanical wiring with standardized electrical connectors and guiding pins. The mechanical aspect of connection is simplified to plug-and-play interfaces with built-in alignment features, eliminating the need for manual routing and connection of individual wires while ensuring reliable electrical contact through precision-machined connector interfaces.

AI summary
A server cabinet, for containing a removable server including a power input port and a connecting element, includes a container, an electrically conductive component, a power supply, a signal connecting base and a rack management controller. The electrically conductive component is connected to the power input port. The power supply is connected to the electrically conductive component to supply power. The signal connecting base includes connectors connected to the connecting element. With the server removed, the power input port and the connecting element are separated from the electrically conductive component and the connector, respectively. The rack management controller is electrically connected to the signal connecting base. With the connecting element electrically connected to the connector, the rack management controller communicates with the server via the connecting element and the one connector and determines the position of the server according to the position of the connector connected to the server.
