Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional server fastening mechanisms are complex, costly, and prone to vibration issues when malfunctioning, leading to potential damage and increased maintenance costs.
Innovation Solution
A locking mechanism with a simple structural design, featuring a slide rail assembly, a housing, a pivotally rotatable handle, a hook element, and a resilient element, which is not directly assembled to the chassis, allowing for easy assembly and replacement, and providing secure fixation through an elastic hook.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional fastening mechanism is directly assembled to the chassis, then the chassis can be fastened to the rack, but the structure becomes complex with more components leading to high costs
Solution Approach 1:
The locking structure is separated from the chassis and mounted on the slide rail assembly instead. This segmentation allows the locking function to be independent from the chassis structure, reducing overall system complexity while maintaining fastening reliability through the dedicated locking mechanism with hook element and resilient element.
Solution Approach 2:
The locking structure is extracted from the chassis assembly and mounted on the slide rail assembly instead. This extraction simplifies the chassis structure by removing the fastening mechanism from it, while the locking function is preserved through the separate locking structure that includes the hook element, handle, and resilient element.
2Reliability
If the fastening mechanism is directly assembled to the chassis, then fastening function is achieved, but assembling and replacement become complicated
Solution Approach 1:
By separating the locking structure from the chassis and mounting it on the slide rail assembly, the locking function becomes an independent module. This segmentation enables easy removal and replacement of the locking structure without affecting the chassis or slide rail assembly, significantly improving ease of repair and maintenance.
Solution Approach 2:
The locking structure is extracted from the chassis and mounted on the slide rail assembly, making it a removable component. This extraction allows the locking structure to be easily detached, repaired, or replaced independently, simplifying maintenance procedures while preserving the fastening function.
3Reliability
If the fastening mechanism is directly assembled to the chassis, then fastening is achieved, but vibrations occur in the chassis during malfunction or damage
Solution Approach 1:
The locking structure is extracted from the chassis and mounted on the slide rail assembly instead. This separation ensures that vibrations or shocks occurring during locking mechanism operation or malfunction are isolated from the chassis, preventing harmful vibrations from affecting components inside the chassis while maintaining fastening reliability.
4Device complexity
If a simple locking structure is used, then costs are reduced, but secure fixation of the chassis may be compromised
Solution Approach 1:
The locking structure uses a resilient element (spring) that provides localized elastic force at the hook element, ensuring secure engagement with the positioning hole. This local quality enhancement at the critical locking point maintains fixation security despite the overall simplicity of the locking structure design.
Solution Approach 2:
The resilient element changes the mechanical parameter of the hook element by providing elastic force, allowing the hook to maintain secure engagement with the positioning hole. This parameter change (elastic deformation) ensures reliable fixation without requiring a complex locking mechanism.
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
The solution reduces costs, minimizes chassis vibrations during operation, and enhances the secure fixation of the chassis to the rack, protecting internal components and simplifying maintenance.
Implementation Method 1
a resilient element for restoring the hook element to an initial position
Implementation Method 2
a handle pivotally rotatable with respect to the housing
Implementation Method 3
A length from the second pivot portion to the push portion is larger than a length from the first pivot portion to the pivot block, so it is much easier for the push portion to drive rotation of the pivot block

AI summary
A locking mechanism and server having the same are provided. The locking structure is assembled to a rack having a positioning hole. The server including a slide rail assembly, a chassis and a locking structure. The slide rail assembly includes an outer slide rail and an inner slide rail. The chassis is fixed to one side of the inner slide rail and movable with the inner slide rail. The locking structure is fastened to the positioning hole and fixed to the inner slide rail. The locking structure includes a housing, a handle, a hook element, and a resilient element. When the handle is rotated to drive the hook element to be detached from the positioning hole, the chassis is released and movable with respect to the rack. The locking structure has a simple structural design, so costs can be reduced.
