Locking-Unlocking Device for Server Hard Disk Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Server products face issues with the hard disk combination being improperly operated during assembly, leading to deformation or damage of the server structure due to insufficient robustness before the base and front modules are fully assembled.
Innovation Solution
A locking-unlocking device comprising a fixing member, stopping member, and locking-unlocking member, which prevents improper operation of the hard disk combination by blocking the movement of the locking-unlocking member until the assembly is complete, using cantilever elements and external forces to transition between locked and unlocked states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the hard disk combination is made liftable with an inclination angle for convenient assembling and disassembling, then the ease of operation is improved, but the structural strength and stability deteriorate before the base module and front module are fully assembled
Solution Approach 1:
The locking member is designed to be movable along the guide groove, allowing it to proactively engage with the locking groove on the hard disk combination. This preliminary locking action prevents the hard disk combination from being improperly lifted before the base module and front module are fully assembled, thus protecting the structural strength while maintaining operational convenience.
Solution Approach 2:
The guide groove acts as an intermediary structure that guides the movement of the locking member. By constraining the locking member to move only along the guide groove, the system ensures that the locking mechanism engages properly with the hard disk combination, preventing premature lifting while allowing convenient operation after assembly.
2Ease of operation
If the locking-unlocking member is made movable to allow convenient locking and unlocking operations, then the ease of operation is improved, but the reliability of preventing improper operation deteriorates
Solution Approach 1:
The locking member is designed with dynamic characteristics, allowing it to move along the guide groove and engage with the locking groove. This dynamic design enables the locking mechanism to adapt to different operational states: remaining locked to prevent improper operation, or being moved to an unlocked position for convenient locking and unlocking operations when needed.
Solution Approach 2:
The locking member is positioned and guided along the guide groove to proactively engage with the locking groove before any improper lifting can occur. This preliminary engagement ensures reliability by preventing improper operation, while the guided movement mechanism allows for convenient intentional unlocking when required.

AI summary
A locking-unlocking device includes a fixing member, a stopping member, and a locking-unlocking member. The stopping member includes a first connection part, a movable part, and a stopping part. The movable part is capable of being moved toward a first direction to a limited extent when the movable part is applied with a first external force. The stopping part is normally in the stopping space. The locking-unlocking member includes a second connection part and a locking part. The locking part is capable of being moved toward a second direction to a limited extent when the locking part is applied with a second external force.
