Tool-Free Storage Drive Fastener Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing assembly and disassembly mechanisms for data storage devices in notebooks are complex and require tools, slowing down the process and increasing complexity during repair or replacement.
Innovation Solution
A mechanism featuring a fastener with a connecting portion and a push button that allows the data storage device to be assembled or disassembled without tools, using a sliding button to engage and disengage a second fastening portion with a first fastening portion, enabling easy installation and removal by sliding along predetermined directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional screws and brackets are used to fasten the data storage device, then the device is securely fixed to the casing, but the assembly and disassembly process becomes complex and requires tools
Solution Approach 1:
The fastening mechanism is segmented into separate functional components: a push button for actuation, a connector with elastic member for fastening, and corresponding engagement features on the bracket. This segmentation allows the complex fastening function to be achieved through simple, tool-free operation while maintaining security.
Solution Approach 2:
The elastic member (spring) automatically engages with the engagement feature when the bracket is inserted, and the push button provides self-contained actuation capability. The mechanism serves itself by using the elastic deformation of the spring to maintain fastening without requiring external tools or complex assembly procedures.
2Productivity
If multiple parts (bracket, screws, connectors) are assembled to the data storage device, then the device is securely installed, but the disassembly process becomes time-consuming and complex
Solution Approach 1:
Multiple fastening functions are merged into a single integrated mechanism. The push button controls both the engagement and disengagement of the elastic member with the engagement feature, while the connector and bracket work together as a unified fastening system. This reduces the number of discrete assembly steps while maintaining secure installation.
Solution Approach 2:
The connector serves multiple functions: it provides electrical connection, mechanical support, and fastening through the elastic member. The bracket simultaneously provides structural support and engagement surfaces for the fastening mechanism. This multi-functionality reduces the number of separate parts needed while achieving secure installation.
3Reliability
If the data storage device is firmly fixed with multiple fastening components, then the installation is stable, but the disassembly process requires unlocking and removing multiple parts
Solution Approach 1:
The fastening mechanism transitions from a static screwed connection to a dynamic spring-based system. The elastic member can elastically deform to engage and disengage smoothly, providing stable fastening during normal operation while allowing easy release when the push button is actuated. This dynamic behavior maintains reliability while improving ease of disassembly.
Solution Approach 2:
The elastic member acts as an intermediary between the push button and the bracket, translating the simple linear motion of the button into the engagement/disengagement of the fastening connection. This intermediary mechanism provides stable fastening through spring force while enabling easy disassembly through button actuation, without requiring direct manipulation of multiple fastening components.

AI summary
An assembling and dissembling mechanism for a data storage device suited to assemble and disassemble a data storage device in a casing having an opening includes a fastener having a connecting portion and a first fastening portion and a push button slidingly disposed at the opening of the casing. The connecting portion is fixed at the data storage device and is connected to the first fastening portion. The push button has a second fastening portion and a pushing portion which are disposed in the casing. The second fastening portion is suitable to be fastened with the first fastening portion to install the data storage device in the casing. When the push button slides by a predetermined distance, it drives the second fastening portion to be separated from the first fastening portion, and the pushing portion pushes the first fastening portion to disassemble the data storage device.
