Hard Disk Drive Bracket Elastic Hook Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hard disk drive fixing members tend to loosen after repeated detachment, failing to securely fix the hard disk drives in position.
Innovation Solution
A hard disk drive bracket featuring a support portion, a tray with a chassis and sidewall, and an elastic piece with a hook-end that deforms to hold the drive in place, ensuring secure fixation even after repetitive use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixing members (screws) are repeatedly detached and reused, then the hard disk drive can be removed and replaced, but the fixing members become loose and fail to firmly fix the hard disk drive in position
Solution Approach 1:
The elastic piece is designed to be deformable, transitioning from an initial state to a deformed state when the hard disk drive is inserted. This dynamic behavior allows the elastic piece to maintain continuous contact force with the drive, ensuring reliable fixation even after repeated detachment and reinstallation operations
Solution Approach 2:
The elastic piece changes its physical state (deformation) in response to the insertion of the hard disk drive. By utilizing elastic deformation as the operating parameter, the fixing mechanism maintains consistent holding force without the loosening issues associated with threaded fasteners that are repeatedly assembled and disassembled
2Reliability
If the elastic piece is designed to deform significantly to accommodate the hard disk drive, then the drive can be securely held, but the structure becomes more complex
Solution Approach 1:
The elastic piece functions as a flexible structural element that deforms to accommodate the hard disk drive while maintaining structural integrity. This flexible component replaces more complex rigid fixing mechanisms, achieving reliable holding through elastic deformation rather than complex assembly structures
Solution Approach 2:
The elastic piece integrates multiple functions into a single component: it provides the holding force, guides the insertion of the hard disk drive, and maintains positional stability. This merging of functions reduces the overall structural complexity compared to using separate components for each function
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 bracket maintains firm fixation of hard disk drives through elastic deformation, resisting fatigue and detaching tests, and supports a range of disk drive sizes and loads, preventing accidental dislodgment.
Implementation Method 1
When the hard disk drive is inserted into the chassis along a bending direction of the second end of the elastic piece, the second end of the elastic piece is elastically deformed and lifted so as to hold the hard disk drive between the chassis and the elastic piece

AI summary
A hard disk drive bracket is configured to be fixed within a hard disk drive holder and includes a support portion, a tray and an elastic piece. The tray is connected to a side of the support portion and has a chassis and a sidewall protruding form a side of the chassis. The elastic piece is suspended above the tray and has a first end fixed to the support portion and a second end forming a hook. The elastic piece and the tray form a holding space therebetween for holding a hard disk drive. When the hard disk drive is inserted into the chassis along a bending direction of the second end of the elastic piece, the second end lifts to hold the hard disk drive between the chassis and the elastic piece. The sidewall fixes the hard disk drive on the chassis with the cooperation of the elastic piece.
