Retractable Connector Assembly for Tool-Free Server Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors require tools for assembly and disassembly, leading to inefficient maintenance and production processes.
Innovation Solution
A retractable connector design with a pull ring and retractable connecting portion that allows for tool-free installation and removal, utilizing a main body, connecting portion, and pull ring for easy attachment and detachment from a host cabinet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to fix the device in the housing, then the connection is secure and reliable, but tools are required for assembly and disassembly resulting in low efficiency
Solution Approach 1:
The connector is divided into a fixed portion and a movable portion that can be independently separated. The movable portion includes a connecting part that engages with the housing and a pulling part that extends outward for tool-free removal. This segmentation allows the connection to remain secure during operation while enabling efficient disassembly by simply pulling the extending part.
Solution Approach 2:
The extending pulling part acts as an intermediary element between the user and the secure connection. It provides a convenient interface for tool-free removal while the actual connection mechanism (movable portion engaging with housing) maintains reliability. This intermediary enables efficient maintenance without compromising connection strength.
2Stability of the object's composition
If traditional fixed connectors are used, then structural stability is maintained, but assembly and maintenance time is increased
Solution Approach 1:
The connector transitions from a static fixed structure to a dynamic system where the movable portion can be easily displaced relative to the fixed portion. The extending pulling part allows the movable portion to be quickly removed from the housing by applying force to the extending part, significantly reducing maintenance time while maintaining structural stability during operational states.
3Strength
If screws and tools are used for connection, then secure attachment is achieved, but potential damage to components increases due to tool intervention
Solution Approach 1:
The tool requirement is extracted and eliminated from the assembly/disassembly process. Instead of requiring screwdrivers or other tools that could damage components, the design uses a pulling part that extends outward to provide a tool-free interface. This allows users to remove the connector by simply pulling the extending part, eliminating the risk of tool-induced component damage while maintaining secure attachment during operation.

AI summary
A connector for installing a device in a host includes a main body for connecting the device, a connecting portion retractably connected to the main body, and a pull ring connected to the connecting portion. The pull ring is configured to be connected to a lifting component. The connecting portion is configured to partially protrude from the main body to connect to a cabinet of the host when the pull ring is not pulled by the lifting component, and retract into the main body to separate from the cabinet of the host when the pull ring is pulled by the lifting component. A host having the connector and a data processing equipment having the host are also provided.
