Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rack-mounted server systems require significant time and effort to connect multiple servers due to the manual handling of cables, which are prone to wear and tear and breakage, leading to increased complexity and cost in installation and maintenance.
Innovation Solution
A system that uses optical sensors, such as LED-photodiode pairs, to automatically align and extend connectors between adjacent servers in a rack system, reducing the need for manual intervention and minimizing cable usage by enabling automated electrical communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual cable connection is used to connect servers, then servers can be interconnected, but it takes significant time and effort, and cables are subject to wear and tear and breakage
Solution Approach 1:
The patent replaces manual mechanical cable connection with an automated connector system that uses sensors to detect alignment and actuators to extend connectors automatically. This substitution eliminates the need for manual cable handling, reducing both connection time and the risk of cable damage from improper handling.
Solution Approach 2:
The connector system performs self-alignment and self-connection through sensor detection and automatic actuation. The system detects when connectors are aligned and automatically extends them to establish electrical communication without requiring manual intervention, making the connection process self-service.
2Adaptability or versatility
If manual cable connection is used to connect servers, then servers can be interconnected, but the steps and supplies involved represent significant complexity in installation and maintenance
Solution Approach 1:
The patent replaces complex manual cable management with an automated connector system that detects alignment and performs connection automatically. This reduces installation and maintenance complexity by eliminating manual steps while preserving the ability to interconnect servers.
Solution Approach 2:
The system uses sensors to detect connector alignment and provides feedback to the control system, which then actuates the connectors automatically. This feedback mechanism simplifies the connection process by providing real-time information about alignment status, reducing the complexity of installation and maintenance.
3Ease of operation
If manual cable connection is used, then servers can be connected, but cables are subject to normal wear and tear and potential breakage if mishandled
Solution Approach 1:
The patent replaces manual cable connection with an automated system that uses sensors and actuators to establish electrical communication. This substitution eliminates the physical wear and tear associated with manual cable handling while maintaining ease of operation through automatic connection.
Solution Approach 2:
The connector system automatically detects alignment and performs connection without manual intervention, eliminating the risk of mishandling cables. The self-service nature of the system ensures that connectors are only engaged when properly aligned, preventing damage from forced connection.

AI summary
An apparatus and method for connecting servers within a rack-mounted server system. In one embodiment, a plurality of servers are positioned in respective bays of a rack. The bays generally constrain adjacent servers in a generally fixed spacing and in face-to-face alignment. A first server is moved within its bay relative to a second server until a connector on the first server is aligned with a mating connector on the second server. Alignment of the two mating connectors is detected by a position sensor, such as an LED-photodiode pair. A signal from the position sensor causes or at least allows the first and second connectors to be moved toward one another, either using a motor or a hand-actuated mechanism, to provide power and data communication between the servers. Once the connection is established, data is optionally transmitted via the optical sensor.
