Data Storage Box Ejection Mechanism with Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hard disk boxes eject hard disks quickly when the operation handle is opened, risking damage due to inadvertent usage or operation during data access or storage, and lack a user-friendly design for safe ejection.
Innovation Solution
A box structure with a two-step operation mechanism that includes a frame module, holder, stop assembly, and operation handle, featuring a damper and elastic elements to slow down the ejection of the data storage device by requiring a specific open angle to be formed before the device can be ejected, utilizing a pivotally connected operation handle to push a movable block and release a stopper, allowing the holder to move slowly with the assistance of a damper.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the operation handle is opened to eject the hard disk box, then the hard disk can be removed quickly, but the hard disk may be damaged due to quick ejection during data access or storage operations
Solution Approach 1:
The ejection operation is segmented into two distinct steps: first rotating the operation handle to release the stopper, then manually pulling the holder to eject the hard disk. This segmentation allows the system to transition from a quick single-step ejection to a controlled two-step process, ensuring the device is properly released before physical removal to prevent damage during data operations.
Solution Approach 2:
The stopper release mechanism is activated in advance by rotating the operation handle before the actual ejection occurs. This preliminary action ensures that the hard disk box is properly disengaged from the chassis and ready for controlled removal, preventing premature ejection that could damage the device during active operations.
2Device complexity
If a conventional handle operation is used, then the structure is simple, but the operation is not user-friendly and may cause damage due to inadvertent usage or shaking
Solution Approach 1:
The operation handle is designed to rotate dynamically to form a specific open angle with the frame module, transitioning from a static simple handle to a dynamic multi-position mechanism. This rotational movement provides visual and tactile feedback to users, ensuring intentional operation and preventing accidental activation while maintaining reasonable structural complexity.
3Productivity
If the hard disk is ejected quickly by opening the handle, then the replacement efficiency is high, but the device lifespan is reduced due to potential damage
Solution Approach 1:
The ejection process is divided into two phases: the stopper release phase (activated by handle rotation) and the physical removal phase (manual pulling). This segmentation maintains productivity by quickly releasing the locking mechanism while extending device lifespan by allowing controlled, deliberate removal rather than abrupt ejection, reducing mechanical stress on connectors and components.
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
The mechanism ensures the data storage device is ejected slowly and safely, preventing damage and enhancing user experience by providing a controlled and prolonged ejection process, thus protecting the device and improving its lifespan.
Implementation Method 1
A damper is disposed between the holder and the frame module. The damper enables the holder to move along the frame module, and the data storage device is movable along with the holder.

AI summary
A box structure for a data storage device is assembled in a chassis having a connector. The box structure includes a frame module, a holder, a stop assembly, and an operation handle. The frame module is provided for accommodating the data storage device. The holder is assembled on one side of the frame module. A damper is disposed between the holder and the frame module, the damper enables the holder to move along the frame module. A stop assembly is disposed at one end of the frame module. The stop assembly includes a stopper and a movable block in contact with the stopper, and the movable block is movable to release the stopper. The operation handle is pivotally connected to the frame module and is rotatable to form an open angle to push the movable block to move.
