Server Tray Mechanism With Linkage For Two-Sided Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional server assembly processes face issues with jamming and poor electrical contact due to one-sided uneven engagement of the tray with the server casing, leading to potential deformation of the server module.
Innovation Solution
A tray mechanism with a handle, transmission member, and linkages that pivot to engage with dual fixing structures on the casing, ensuring two-sided engagement and stable positioning of the server module, allowing for smooth assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If one-sided engagement design is used, then assembly process is simple, but server module may become oblique and cause jamming
Solution Approach 1:
The patent employs asymmetric engagement structures where the handle and link mechanism are positioned to create non-uniform engagement forces that compensate for the inherent asymmetry in module insertion, ensuring both sides engage properly despite the one-sided actuation point
Solution Approach 2:
The link mechanism serves as an intermediary between the handle and the tray engagement points. It transforms the single-point handle motion into coordinated two-sided engagement, mediating the force distribution to prevent module obliquity while maintaining assembly simplicity
2Force
If handle is positioned far from connection ports, then engagement leverage is sufficient, but server module deformation may occur
Solution Approach 1:
The link mechanism provides dynamic force distribution, adjusting the engagement forces in real-time during the insertion process. This allows sufficient leverage to be applied through the handle while the forces are dynamically balanced to prevent excessive stress on the server module connections
Solution Approach 2:
The engagement force is segmented into multiple application points through the link mechanism, which distributes the total force across different locations on the tray and module. This segmentation prevents concentration of stress at any single point, maintaining module integrity while achieving adequate engagement leverage
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 two-sided engagement design prevents module obliquity and deformation, ensuring proper electrical contact and improving assembly efficiency and quality by facilitating quick and secure insertion and removal of the tray.
Implementation Method 1
The first link has a first shaft portion and a first driven portion. The first shaft portion is pivoted to the holding portion and has a first engaging structure. The first driven portion is slidably disposed through the first slot.
Implementation Method 2
The handle has a pivot portion and a driving portion movably connected to the front portion. The pivot portion is pivoted to the holding portion to make the handle pivotable between a releasing position and a mounting position relative to the tray.

AI summary
A server apparatus includes a casing having an opening and a fixing structure away from the opening, a tray mechanism and a server module. The tray mechanism includes a tray, a transmission member slidably disposed on the tray and having a slot, a link having an engaging structure and being slidably disposed through the slot, and a handle movably connected to the transmission member and pivoted to the tray. The server module is disposed on the tray. When the tray is disposed in the casing and the handle pivots to a mounting position, the transmission member slides relative to the tray to drive the link to pivot, so as to rotate the engaging structure to be engaged with the fixing structure.
