Screwless HDD Drawing Box with Elastic Snapping Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current HDD swappable modules require time-consuming screw-based assembly and replacement processes, leading to complex structures and increased volume, which complicates the process of adding or removing hard disk drives.
Innovation Solution
A screwless hard disk drive drawing box design featuring a hard disk drive cartridge with fixing pins and elastic snapping members that securely engage with the HDD's side plates without the need for screws, allowing for quick assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to fix the HDD in the drawing box, then the HDD is securely fixed, but the assembly and replacement process becomes time-consuming and complex
Solution Approach 1:
The patent extracts the screw fastening mechanism from the drawing box structure and replaces it with integrated elastic snapping members that are directly formed on the sideboards. This eliminates the need for separate screw components while maintaining secure fixing, thereby reducing assembly time and complexity.
Solution Approach 2:
The elastic snapping members are designed to automatically engage with the HDD side plates through elastic deformation and recovery. The members possess self-fixing capability through their elastic properties, eliminating the need for manual screw tightening operations and enabling quick assembly and replacement.
2Loss of time
If a wedging member is used to replace screws, then the assembly process becomes faster, but the structure becomes more complex and volume increases
Solution Approach 1:
The patent merges the elastic snapping members directly into the sideboards of the drawing box, making them integral parts of the structure. This integration eliminates the need for separate wedging members and reduces overall structural complexity while maintaining the speed advantage of screwless assembly.
Solution Approach 2:
The sideboards serve multiple functions: they provide structural support for the drawing box and simultaneously incorporate the elastic snapping members for fastening the HDD. This multi-functionality reduces the number of separate components needed, simplifying the overall structure while enabling quick assembly.
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
This design simplifies the structure of HDD swappable modules, reduces assembly and replacement time, and eliminates the need for screws, making the process more efficient and convenient.
Implementation Method 1
The elastic elements have elasticity and are deformable when the snapping bump is forced, and after a force applied to the snapping bumps is removed, the snapping bumps are able to recover to an original position before moving by the elasticity of elastic elements.

AI summary
A screwless hard disk drive (HDD) drawing box and a HDD swappable module are provided, which includes a HDD cartridge for receiving a hard disk drive. The HDD cartridge has a bottom board, and two sideboards connected to two opposite sides of the bottom board. The two side plates of the hard disk drive are close to the two sideboards. One of the sideboards has a plurality of fixing pins. The other sideboard of the HDD cartridge has a plurality of elastic snapping members opposite to the fixing pins. Each of the elastic snapping members has a snapping bump and an elastic element. Each snapping bump is arranged on the elastic element at the other sideboard of the HDD cartridge opposite to the fixing pins. The fixing pins and the snapping bumps are inserted in the thread holes of the two side plates of the hard disk drive.
