Removable Hard Disk Mounting Device With Pivoting Second Holders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional removable hard disk drives are inconvenient to assemble and disassemble, requiring screwdrivers and reducing the efficiency of repair or replacement work due to the need to remove and reattach screws.
Innovation Solution
A removable hard disk device design featuring a handle, first holder, hard disk drive, and pivotally connected second holders that allow for tool-free assembly and disassembly by engaging and disengaging the second holders with the handle and hard disk drive.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws are used to fasten the hard disk drive to the hard disk box, then the connection strength is improved, but the ease of operation deteriorates due to requiring screwdrivers and multiple steps for assembly and disassembly
Solution Approach 1:
The mounting device is divided into separate components: a first holder that remains with the hard disk box, and a second holder with a handle that attaches to the hard disk drive. This segmentation allows the hard disk drive to be easily removed by simply detaching the second holder, eliminating the need for screws while maintaining secure connection during operation.
Solution Approach 2:
The second holder is designed to be dynamically attachable and detachable to the hard disk drive through engagement features. This dynamic connection allows quick assembly and disassembly without tools, while the engagement mechanism ensures sufficient connection strength when mounted, resolving the contradiction between strong connection and ease of operation.
2Reliability
If screws are used to fasten the hard disk drive, then the reliability of connection is improved, but the productivity deteriorates due to time-consuming assembly and disassembly processes
Solution Approach 1:
The second holder is pre-equipped with engagement features that align with corresponding features on the hard disk drive. This preliminary design allows maintenance workers to quickly attach or detach the holder by simple insertion or removal actions, significantly reducing maintenance time while ensuring reliable connection through the pre-designed engagement mechanism.
3Device complexity
If the hard disk drive is permanently mounted in the hard disk box, then the device complexity is reduced, but the ease of repair deteriorates as the hard disk drive cannot be easily removed for maintenance
Solution Approach 1:
The second holder with handle is extracted as a separate, removable component that attaches to the hard disk drive. This extraction allows the hard disk drive to be easily removed from the hard disk box by simply detaching the second holder, greatly improving ease of repair while adding minimal complexity to the overall system.

AI summary
A removable hard disk device includes a handle, a first holder, a hard disk drive located between the handle and the first holder, and two second holders pivotally connected to ends of the first holder and detachably connected to ends of the handle with the two second holders firmly holding the hard disk drive there between and detachably connected to the disk drive. When the second holders are forced to pivotally move outwardly relative to each other, the second holders will be separated from the first holder and the handle such that the hard disk drive can be dismounted from the first holder without using any tool.
