Server Hard Disk Tray Handle Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional server devices require complex and inconvenient procedures for mounting and removing hard disk units due to the need to tighten or loosen multiple screws, making the process inefficient and time-consuming.
Innovation Solution
A server device design featuring a hard disk tray with lugs and a handle that allows for easy installation and removal of hard disk units by rotating the handle to engage and disengage the units with the tray, utilizing a position-limiting hole and projection system for secure positioning, and a connector system for electrical connection, eliminating the need for additional assembly tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to directly secure the hard disk on a support bracket, then the hard disk is firmly fixed, but the mounting and removal procedures become complicated and time-consuming
Solution Approach 1:
The support bracket is divided into a fixed portion and a movable portion that can slide relative to each other along guide rails. The hard disk is secured to the movable portion, allowing it to be easily inserted and removed by sliding the movable portion along the guide rails without dealing with multiple screws.
Solution Approach 2:
The fastening function is extracted from the support bracket and transferred to the guide rails through a locking mechanism. The movable portion engages with the guide rails and can be locked into position, eliminating the need for multiple screws while maintaining firm fixation.
2Reliability
If a slide-rail is used to slide the hard disk into a support bracket and then screws are used to secure it, then the hard disk is securely mounted, but the procedure becomes more complex and inconvenient
Solution Approach 1:
The sliding and fastening functions are merged into a single integrated mechanism. The movable portion slides along the guide rails and is automatically locked into position, combining the insertion and securing operations into one simple action that reduces procedural complexity.
Solution Approach 2:
The guide rails and movable portion form a self-locking mechanism that automatically secures the hard disk in position during the sliding insertion process, eliminating the need for separate fastening operations with screws.

AI summary
A server device includes a tray having a lug, a hard disk unit removably disposed on the tray, and a handle pivotally connected to two opposite sides of the hard disk unit. The lug is formed with a slot thereon to define two inner edges opposite to each other. The handle is provided with a protrusion arranged in the slot. When the handle is rotated towards one end of the hard disk unit, the protrusion is rotated along with the handle to contact and push one of the inner edges of the lug, such that the hard disk unit is restrained by the tray after the hard disk unit is slid in relative to the tray.
