Tool-Free Hard Drive Enclosure with Integrated Pin and Hook
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hard drive removable enclosures require tools for installation and can lead to loss of small components during the process, making the installation and removal of hard drives inconvenient.
Innovation Solution
A hard drive removable enclosure design featuring a carrier plate with a primary positioning pin and hook, along with an elastic arm and lock button, allows for tool-free installation by using securement holes on the hard drive, where the primary positioning pin secures the drive from the bottom and the hook locks into lateral holes, with a secondary positioning pin and sliding slots for secure placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to fasten the hard drive into the enclosure, then the hard drive is securely fixed, but the installation process becomes complicated and requires tools
Solution Approach 1:
The patent extracts the fastening function from traditional screws and replaces it with an integrated positioning pin structure that combines positioning and securing functions. The positioning pin with elastic arm and lock button eliminates the need for separate fastening components, enabling tool-free installation while maintaining securement reliability.
Solution Approach 2:
The elastic arm with lock button provides self-locking functionality that automatically secures the hard drive without requiring external tools or complex fastening operations. The elastic arm engages with the positioning hole and locks into place through the lock button mechanism, enabling the system to secure itself during installation.
2Reliability
If screws are used to fasten the hard drive, then the hard drive is securely fixed, but tiny components may be lost during installation/removal
Solution Approach 1:
The patent merges the positioning pin, elastic arm, and lock button into a single integrated structure that is permanently attached to the enclosure. This eliminates separate fastening components that could be lost, while maintaining the securement function through the integrated self-locking mechanism.
3Stability of the object's composition
If a traditional box structure with six flat surfaces is used, then the enclosure is structurally sound, but the volume and manufacturing cost increase
Solution Approach 1:
The patent extracts unnecessary structural elements from the traditional six-sided box design, retaining only the essential carrier plate with positioning features. This simplified structure reduces volume and manufacturing complexity while maintaining sufficient structural integrity for hard drive containment and securement.
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
Enables easy, tool-free installation and removal of hard drives, reducing the risk of component loss and simplifying the process, while also reducing the enclosure's volume and manufacturing costs due to a simplified structure.
Implementation Method 1
the elastic arm is configured to bend from the blocking board toward the primary positioning pin

AI summary
A hard drive module includes a hard drive and a hard drive removable enclosure. The hard drive includes a bottom surface having a first securement hole formed to indent inward thereon and a lateral surface having a second securement hole formed to indent inward thereon. The second securement hole is fluidly connected to the first securement hole. The bottom surface of the hard drive is received on a carrier plate. A primary positioning pin penetrates into the first securement hole from the bottom surface of the hard drive. A hook penetrates into the second securement hole from the internal of the first securement hole. Accordingly, by using the primary positioning pin with its rear end formed of the hook thereon for securing the hard drive, the hard drive can be installed and secured inside the hard drive removable enclosure without the use of any tools.
