Tool-Free Hard Disk Mounting via Rotating Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing server hard disk mounting systems require tools for assembly and disassembly, complicating the process and increasing the need for manual intervention.
Innovation Solution
A hard disk mounting device with a rotatable element that presses against a fastening element, allowing the hard disk to be slid away from the frame without tools, utilizing an elastic buckle and torsion spring mechanism for easy detachment and reattachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to mount the hard disk to the frame, then the hard disk is securely fixed, but a tool is required for assembly and disassembly
Solution Approach 1:
The mounting device enables self-service operation through the rotating element mechanism. The elastic buckles automatically engage with the rotating element during insertion, and the same rotating element can release them by rotating in the opposite direction, eliminating the need for external tools while maintaining secure mounting
Solution Approach 2:
The mounting device transitions from a static screw connection to a dynamic system where the rotating element can change the state of the elastic buckles. The elastic buckles can deform elastically to engage or disengage from the rotating element, providing both secure fixation and easy release through rotational motion
2Reliability
If a tool is required for assembly and disassembly, then secure mounting is achieved, but manual intervention and complexity increase
Solution Approach 1:
The device performs its own mounting and dismounting functions through the rotating element mechanism. The elastic buckles automatically engage with the rotating element when the hard disk is inserted, and rotating the element in reverse automatically releases them, making the system self-sufficient without requiring external tools or complex procedures
Solution Approach 2:
The rotating element acts as an intermediary between the operator and the elastic buckles. Instead of directly manipulating screws or complex fastening mechanisms, the operator simply rotates the element, which mediates the engagement and disengagement of the elastic buckles, simplifying the interface while maintaining secure mounting

AI summary
A device for mounting a hard disk in a server or other housing includes a frame, a hard disk, and a rotatable element. The frame defines a receiving space thereon and includes an end wall. The hard disk is slidably received in the receiving space. The hard disk includes a fastening element facing to the end wall. The hard disk is slidably attached to the end wall and the fastening element is locked to the end wall. The rotatable element is attached to the end wall and can rotate from a first position to a second position to abut the fastening element. The rotatable element can be pressed against the fastening element to unlock and the hard disk can be slidably detached from the end wall.
