Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for attaching data storage devices to computer enclosures, such as using bolts, are complex, time-consuming, and require additional space, which is not suitable for the trend towards miniaturization in the computer industry.
Innovation Solution
A fixing mechanism comprising a case with guiding pins and a latch member, where the data storage device has thumb screws with neck portions that slide into sliding channels, and a resilient arm that snaps into a positioning space to securely attach and detach the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bolts are used to attach data storage devices to drive brackets, then secure attachment is achieved, but the attachment process becomes complicated and time-consuming
Solution Approach 1:
The patent replaces the traditional bolt-based mechanical fastening system with a snap-fit mechanism. The guiding pins on the data storage device engage with sliding channels in the drive bracket, and the resilient arm provides automatic latching through elastic deformation, eliminating the need for bolts and simplifying the attachment process while maintaining secure fixation.
2Reliability
If bolts are used to attach data storage devices, then secure attachment is achieved, but additional work space is required inside the computer enclosure
Solution Approach 1:
The patent extracts the fastening function from the data storage device itself and transfers it to the drive bracket through the resilient arm mechanism. This allows the attachment system to be more compact and better utilize the available space inside the computer enclosure, eliminating the need for additional work space required by bolt-based systems.
3Reliability
If conventional attachment methods are used, then data storage devices can be securely fixed, but installation and removal processes are time-consuming
Solution Approach 1:
The patent incorporates guiding pins that automatically align with and engage the sliding channels during insertion. The resilient arm is pre-positioned to automatically latch onto the guiding pins, eliminating the need for manual fastening operations. This preliminary alignment and automatic engagement significantly reduce installation and removal time while ensuring reliable device fixation.

AI summary
An exemplary fixing mechanism for a data storage device includes a case, and a latch member. The data storage device includes two pairs of guiding pins attached to sidewalls thereof. The case includes a first panel, and a second panel. The first panel includes an opening defined therein, and a first plate perpendicularly extending from an edge of the opening. The second panel includes a bracket to hold a component other than the data storage device therein. The bracket includes a wall parallel to the first plate. A pair of first sliding channels is defined in the wall and a second sliding channel is defined in the first plate, for slidably receiving the guiding pins therein. The latch member is attached to the first plate and includes a resilient arm. A positioning space is defined in the resilient member to hold the corresponding guiding pin therein.
