Sliding Electrical Connections for Server Racks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing datacenter systems require conventional electrical cables and outlets for powering compute components, which can complicate maintenance and diagnostics, as components need to be disconnected for access.
Innovation Solution
The implementation of sliding electrical connection systems within server racks that use integrally formed electrical contacts and conductive strips to maintain power to compute components while they are slid in and out, eliminating the need for conventional cables and plugs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional electrical cables and outlets are used to power compute components, then power can be supplied to components, but components need to be disconnected for access during maintenance and diagnostics
Solution Approach 1:
The patent implements a sliding drawer mechanism that allows compute components to be physically moved along a track while maintaining continuous electrical connection. The dynamic sliding action enables components to be pulled out for access and pushed back in without disconnection, resolving the contradiction between accessibility and downtime by making the system adaptable during maintenance operations
Solution Approach 2:
The electrical connection system maintains continuous power and data connectivity throughout the entire sliding motion of the compute component. The contacts are designed to remain engaged during the drawer's movement, ensuring that useful action (power supply and data transmission) continues uninterrupted, thereby eliminating downtime during maintenance access
2Ease of operation
If compute components are disconnected for access during maintenance, then physical access is achieved, but power and electrical connections are lost
Solution Approach 1:
The sliding drawer mechanism with integrated electrical contacts allows the compute component to be dynamically moved to an accessible position while maintaining continuous electrical connection. The contacts are positioned and designed to remain engaged throughout the sliding range, enabling both physical access and continuous power supply simultaneously
Solution Approach 2:
The sliding drawer mechanism acts as an intermediary between the compute component and the rack structure, allowing physical access while the electrical contacts serve as intermediaries to maintain continuous power and data connections during the movement and access process
3Reliability
If conventional cables and plugs are used, then electrical connections can be made, but the system becomes more complex with disconnected components
Solution Approach 1:
The patent merges the mechanical sliding mechanism with the electrical connection system into a single integrated structure. The electrical contacts are built into the drawer and track assembly, combining what were previously separate elements (cables, plugs, and mechanical support) into one unified system, thereby reducing overall complexity while maintaining reliable connections
Solution Approach 2:
The patent extracts and eliminates the need for conventional removable cables and plugs by integrating electrical contacts directly into the sliding mechanism. This extraction of the connection function from separate cable assemblies and its integration into the drawer structure simplifies the system by removing unnecessary components

AI summary
Slidable electrical connection systems are described. An example system may include a compute component that may include a slide component and an elongate conductive structure disposed at an outer casing of the compute component. The slide component may permit the compute component to move linearly between an extended position and a stowed position. The elongate conductive structure is configured and positioned to engage with an electrical contact of a support surface to form an electrical connection. The electrical connection is maintained at least while the compute component is moved between the extended position and the stowed position.
