Hard Disk Fixing Device Bayonet Lock Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hard disk fixing methods, such as screw fixing and screwless methods, result in low installation and maintenance efficiency due to complex processes and the need for multiple screws, especially in limited spaces.
Innovation Solution
A hard disk fixing device featuring a hard disk holder with a locking mechanism comprising a handle, transmission member, and locking member, where the locking member with a bayonet engages with a fixing member to securely fasten or release the hard disk, reducing the need for multiple screws and simplifying installation and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw fixing method is used to secure hard disk in hard disk holder, then the hard disk can be firmly fixed, but multiple screws are required resulting in low installation and maintenance efficiency
Solution Approach 1:
The patent combines multiple screw fixing operations into a single integrated locking mechanism. The locking member integrates the functions of multiple screws into one component that can be operated simultaneously, reducing the number of fastening operations from multiple individual screw tightenings to a single locking action while maintaining firm fixation of the hard disk.
Solution Approach 2:
The locking member serves multiple functions: it acts as a fastening mechanism, a positioning element, and a release mechanism all in one component. This multi-functional design eliminates the need for separate screws and tools, allowing the same component to secure the hard disk during installation and release it during maintenance, thereby improving both installation and maintenance efficiency.
2Reliability
If multiple screws are used to fix the hard disk, then the hard disk can be securely held, but tools are required for removal resulting in low maintenance efficiency
Solution Approach 1:
The locking mechanism is designed to be self-operating without requiring external tools. The locking member can be manually engaged and disengaged by the user through simple hand operations, eliminating the need for screwdrivers or other removal tools. This self-service capability allows users to quickly install and maintain hard disks without specialized tools, significantly improving maintenance efficiency while maintaining secure fixation.
3Area of stationary object
If hard disk holder is assembled in limited operating space, then space is utilized efficiently, but disassembly is required for maintenance further reducing maintenance efficiency
Solution Approach 1:
The patent segments the hard disk holder into modular components that can be independently accessed. The locking mechanism is designed so that the locking member can be operated independently without requiring disassembly of the entire hard disk holder from the chassis. This segmentation allows maintenance personnel to quickly access and service individual hard disks within the compact holder structure, maintaining space efficiency while improving maintenance accessibility.

AI summary
A hard disk fixing device includes a handle, a locking member, a transmission member and a hard disk holder. A first side surface of the hard disk holder is provided with a locking hole, which is used for a fixing member of a hard disk to protrude from the hard disk holder. The handle is connected with the first side surface. The transmission member is rotatably connected with the handle. The locking member is rotatably connected with the transmission member. A locking bayonet on the locking member is engaged with the fixing member.
