Innovation Solution
A hard disk assembly device featuring a flexible fixing frame and a fixing bracket with positioning portions and fastening mechanisms that allow for tool-free disassembly and assembly, enabling quick and convenient installation, repair, and replacement of hard disks without the need for screws.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to fix the hard disk to the case, then the hard disk is securely fixed, but the assembly process becomes complicated and time-consuming
Solution Approach 1:
The fixing mechanism is divided into multiple positioning portions (first positioning portion on hard disk, second positioning portion on bracket, third positioning portion on fixing frame) that work together to achieve secure fixation without screws. Each positioning portion engages with its counterpart to provide stable mounting while enabling quick release.
Solution Approach 2:
The fixing frame is designed to be flexible rather than rigid, allowing it to deform elastically during assembly and disassembly. This dynamic characteristic enables the fixing frame to automatically engage with positioning portions and later release easily by pulling the draw tape, transforming a static screw-fixed system into a dynamic snap-fit system.
2Reliability
If screws are used to fix the hard disk, then secure fixation is achieved, but tool-free disassembly becomes impossible
Solution Approach 1:
The fixing frame incorporates a draw tape that enables the user to easily pull and release the fixing frame from the bracket without requiring any tools. The elastic deformation of the fixing frame during this process allows automatic disengagement of the positioning portions, making the disassembly process simple and tool-free while maintaining secure fixation during normal operation.
3Ease of operation
If a flexible fixing frame is used, then easy disassembly is enabled, but the fixing strength may be reduced
Solution Approach 1:
The fixing frame utilizes elastic curvature and deformation characteristics to achieve both strong fixation and easy release. The frame's curved elastic structure allows it to flex during assembly to engage positioning portions securely, then flex again during disassembly to release them, maintaining fixing strength while enabling ease of operation.
