Hard Disk Drive Tray Latch Mechanism for Screwless Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hard disk drive trays require screws to be removed for maintenance, which is time-consuming and inefficient, as they need to be unscrewed and re-screwed for installation and removal.
Innovation Solution
A hard disk drive tray with a pivotable engagement component and a switch that allows the tray to be slidably mounted on a casing, featuring a pivot part, arm parts, and a hook part, where the switch can pivot between engaged and released positions, using elastic components to disengage the hook from the casing, enabling easy installation and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If screws are used to fix the hard disk drive tray on the server cabinet, then the tray can be securely fixed, but the maintenance process becomes time-consuming and inefficient due to the need to remove and reinstall screws
Solution Approach 1:
The patent transforms the static screw-fixed connection into a dynamic latch mechanism that can be quickly engaged and disengaged. The latch member can pivot between locked and unlocked positions, allowing the tray to be rapidly installed or removed without manual screw operations, directly resolving the contradiction between secure fixation and maintenance efficiency
Solution Approach 2:
The latch mechanism incorporates an elastic component that automatically returns the latch member to its locked position after being released. This self-resetting feature eliminates the need for manual re-engagement operations, making the installation and removal process even faster while maintaining secure fixation during operation
2Productivity
If a latch mechanism is used instead of screws, then the ease of installation and removal is improved, but the device complexity increases due to additional components like the latch member and elastic component
Solution Approach 1:
The latch member is integrated with the tray body as a unified structure, where the latch member forms an integral part of the tray assembly. This merging reduces the number of separate components and simplifies the overall structure, counteracting the complexity increase from replacing screws with a latch mechanism
Solution Approach 2:
The latch member serves multiple functions: it provides secure locking during operation, enables quick release for maintenance, and automatically resets through the elastic component. This multi-functionality consolidates several operations into a single mechanism, improving productivity without proportionally increasing structural complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates efficient installation and removal of the hard disk drive tray by allowing it to be drawn out and reinserted without the need for screws, enhancing maintenance efficiency and compatibility with various server cabinets.
Implementation Method 1
The first elastic component is disposed on the engagement component and configured to force the engagement component to pivot with respect to tray body
Data Source
AI summary
The disclosure provides a hard disk drive tray including a tray body, an engagement component, a first elastic component and a switch. The engagement component includes a pivot part, a first arm part, a second arm part and a hook part connected to each other. The pivot part is pivotably disposed on the tray body. The first elastic component is disposed on the engagement component and can force the engagement component to pivot. The switch is movably disposed on the tray body. When the switch is in an engaged position, the switch and the second arm part are engaged with each other, and the hook part is engaged with a casing. When the switch is in a released position, the switch is disengaged from the second arm part, and the first elastic component pivots the engagement component so as to disengage the hook part from the casing.
