Server Slide Rail Locking Plate for Easy Removal and Impact Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sliding mechanisms for servers in personal computers are complex, costly to manufacture, and prone to damage from great impacts due to the need for large external forces during removal.
Innovation Solution
A sliding mechanism with a resilient plate and a simplified structure, featuring a locking element that extends through a through hole in an end plate, allowing for secure engagement and easy removal without deforming under impact, using a slide frame with a partially bent end plate and securing elements for stable mounting within the computer casing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional sliding mechanism with resilient stick and engaging hook is used for securing the exterior plates, then the server can be retained securely within the casing, but the structure becomes complicated and manufacturing expense increases
Solution Approach 1:
The patent combines the locking element and resilient plate into a single integrated component that performs both locking and securing functions. The locking element with protrusions engages with corresponding recesses in the end plate, while the resilient plate provides the necessary elastic deformation capability, eliminating the need for separate resilient sticks and engaging hooks.
Solution Approach 2:
The locking element serves multiple functions: it provides secure retention through engagement with the end plate, allows for easy release through lateral movement, and provides impact resistance through the resilient plate's elastic properties. This multi-functional design simplifies the overall structure while maintaining reliability.
2Device complexity
If a resilient connection rod is used for securing the exterior plate, then the structure can be simplified, but the resilient connection rod may deform permanently if external force applied is too heavy
Solution Approach 1:
The patent applies local quality by creating specific engagement features (protrusions and recesses) at critical locations on the locking element and end plate. These localized structural features provide enhanced mechanical interlocking at the engagement points while maintaining overall structural simplicity, preventing permanent deformation under heavy loads.
Solution Approach 2:
The locking mechanism combines rigid components (locking element with protrusions, end plate with recesses) with elastic components (resilient plate). This composite approach provides both the structural integrity needed to resist permanent deformation and the elastic flexibility needed for easy assembly and disassembly.
3Ease of operation
If the resilient plate is designed to allow easy removal by lateral movement, then the server can be removed without large external forces, but the structure may become less resistant to impact
Solution Approach 1:
The patent employs dynamics by designing the locking element to transition between two stable states: engaged (for secure retention) and disengaged (for easy removal). The resilient plate enables this dynamic transition through controlled elastic deformation, allowing the system to adapt between security and ease of operation based on operational requirements.
Solution Approach 2:
The locking element is segmented into distinct functional zones: engagement protrusions for secure locking, lateral movement surfaces for easy release, and connection points to the resilient plate. This segmentation allows each zone to optimize its function independently, providing both ease of removal and impact resistance.

AI summary
A sliding mechanism with locking function includes a slide frame and a resilient plate. The slide frame includes opposite front and rear ends and an end plate formed at the front end and extending outward from the front end in a transverse direction relative to a longitudinal length of the slide frame. The end plate is formed with a through hole. The resilient plate has a width smaller than that of the slide frame, a rear section fixed to the slide frame and a front section opposite to the rear section and formed with a locking element exposed to an exterior of the through hole in the end plate in such a manner that the locking element is movable limitedly and resiliently in the transverse direction upon an external force applied thereto.
