Swivel-Hook Locking Structure for Screwless Server Storage Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current screw locking methods for memory storage devices in computer servers are inefficient, requiring multiple screws, increasing assembly time, and risking damage to components during installation or removal, while also complicating maintenance and replacement processes.
Innovation Solution
A locking device comprising a casing, pressing adjustment member, pivot, swivel hook, and rotating reset member, allowing for quick disassembly and assembly by rotating the movable frame on the tray, with the pivot and rotation axes separated to enhance leverage and reduce space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw locking methods are used to fix memory storage devices, then the devices can be securely locked, but the assembly time increases and maintenance becomes complicated
Solution Approach 1:
The locking device is divided into separate functional components: a locking body with locking element, a pressing adjustment member with hook portion, and a swivel hook. This segmentation allows each component to perform its specific function independently, enabling quick engagement and disengagement without requiring multiple screws, thus reducing assembly time while maintaining reliable locking through the coordinated action of these segmented parts
Solution Approach 2:
The locking mechanism transitions from a static screw-fixed state to a dynamic state where the swivel hook can rotate and the pressing adjustment member can be adjusted. The swivel hook rotates to engage or disengage from the locking body, and the hook portion of the pressing adjustment member can be pressed to adjust the locking force. This dynamic capability allows rapid locking and unlocking operations, significantly reducing maintenance time while ensuring reliable fixation through controlled dynamic movement
2Strength
If multiple screws are used for locking, then the locking strength increases, but the complexity of assembly and disassembly increases
Solution Approach 1:
Multiple locking functions that would traditionally require separate screws are merged into a single integrated locking device. The locking body combines the locking element and pressing adjustment member into one unit, which can be operated as a single component. The swivel hook integrates the rotation and engagement functions. This merging reduces the number of parts and assembly steps while maintaining adequate locking strength through the combined mechanical action of the integrated components
Solution Approach 2:
The locking device performs multiple functions through its components: the locking body provides locking and pressing functions, the pressing adjustment member with hook portion provides adjustment and locking force application, and the swivel hook provides rotation and engagement. This multi-functionality eliminates the need for separate screws for each function, reducing assembly complexity while ensuring sufficient locking strength through the universal design that combines multiple operations into single components
3Ease of manufacture
If screw holes are used for locking, then the locking method is simple, but the risk of damaging components during installation increases
Solution Approach 1:
The locking mechanism extracts the screw element entirely from the system and replaces it with a pressing adjustment member that uses a hook portion to engage with the locking body. This extraction eliminates the need for screw holes in the memory storage device, thereby removing the risk of damage to the device during installation. The locking simplicity is maintained through the straightforward pressing and rotating motions required to engage and disengage the locking mechanism
4Volume of moving object
If the pivot and rotation axes are on the same axis, then the structure is compact, but the leverage ratio is reduced
Solution Approach 1:
The design deliberately creates asymmetry by positioning the pivot axis and rotation axis at different locations rather than aligning them. The pivot is positioned at one location while the rotation axis is offset, creating an asymmetric configuration that increases the lever arm length. This asymmetric arrangement provides a larger leverage ratio, making it easier to apply force during locking and unlocking operations, while the overall compactness is maintained through the efficient use of space in the asymmetric layout
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
Facilitates easy and rapid replacement of computer parts by allowing the tray to be opened to a maximum angle for access, while maintaining stability and reducing the risk of component damage, thus enhancing maintenance efficiency and reducing downtime.
Implementation Method 1
the hook portion of the pressing adjustment member generates elastic reset and the two fixed portions are re-accommodated in the accommodation groove
Implementation Method 2
the two fixed portions of the pressing adjustment member break away from an accommodation groove outward and press against the swivel hook of the respective locking device
Implementation Method 3
The hook end of the swivel hook rotates downward and snaps into the positioning frames at the bottom of the chassis to form a fixed state
Implementation Method 4
increasing the pivot distance between the force application point and the locking device to form a larger leverage ratio, making it easier to apply force

AI summary
A locking device includes a casing composed of a cover and a back plate with a storage chamber and an accommodation groove defined in the cover, a pressing adjustment member set in the accommodation groove with the hook portion thereof inserted through a passage in the accommodation groove and stopped against the cover, a pivot mounted between the cover and the back plate, and a swivel hook and a rotating reset member both sleeved onto the pivot. The swivel hook has a hook end extending out of the casing and rotatably locked in a chassis. The hook portion of the pressing adjustment member adjusts the tightness of the cover, the swivel hook and the back plate according to whether the hook portion of the pressing adjustment member resists the inner wall of the chassis.
