Pivoting Server Tray Latch for Space-Saving Chassis Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Blade servers in modular designs face challenges with handle-based tray extraction, which occupy space, hinder component installation, and risk damage during removal.
Innovation Solution
A tray with a pivotally connected operating member that rotates between closed and opened positions, allowing secure locking and unlocking within a chassis, ensuring correct assembly and disassembly sequences to prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a handle is equipped on the front bezel of the tray for extraction, then the tray can be easily removed, but the handle occupies the setting space of the front bezel, making it hard to install more components and add heat dissipation holes
Solution Approach 1:
The operating member is extracted from the front bezel area and relocated to the side surface of the tray body. This extraction eliminates the space occupation problem while maintaining the tray extraction function, as the operating member can still be used to engage and disengage the tray from the chassis.
Solution Approach 2:
The operating member is repositioned from a frontal location (front bezel) to a lateral location (side surface of tray body). This dimensional change allows the operating member to function independently of the front bezel space, enabling both component installation and heat dissipation hole addition in the front bezel area.
2Ease of operation
If the handle can be directly pulled outward to extract the tray and blade server concurrently, then extraction is simplified, but the blade server may be damaged
Solution Approach 1:
The operating member is designed to first disengage from the chassis locking structure before the tray can be fully pulled out. This preliminary action ensures that the blade server remains constrained to the tray during extraction, preventing it from shifting or becoming damaged while maintaining easy tray removal.
Solution Approach 2:
The extraction process is segmented into two distinct phases: first, the operating member disengages the tray from the chassis; second, the tray (with blade server still constrained) is pulled out. This segmentation prevents concurrent movement of both tray and blade server that could cause damage.
3Area of stationary object
If the operating member is hidden inside the tray body, then more components can be installed in the front bezel area and heat dissipation holes can be added, but the operating member must be pivotally connected to enable rotation between closed and opened positions
Solution Approach 1:
The operating member is designed as a dynamic component that can rotate between a closed position (when not in use) and an opened position (when tray extraction is needed). This dynamic capability allows the operating member to be hidden inside the tray body most of the time, maximizing front bezel space utilization while providing functionality when required.
Data Source
AI summary
A data processing device includes a chassis and at least one electronic component. The chassis includes a casing and a tray disposed in the casing. The tray includes a tray body and an operating member pivotally connected to the tray body. The tray body has an accommodating space. When the operating member is located at a closed position, the operating member and the casing are locked, and the at least one electronic component is able to be accommodated in the accommodating space. When the at least one electronic component is removed from the accommodating space, the operating member is able to rotate from the closed position to an opened position located in the accommodating space to be unlocked from the casing, so as to allow the tray to be removed from the casing.
