High Density Server Chassis Friction Carrier Tray
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional 1U server rack chassis has limited storage capacity due to fixed dimensions and physical size constraints, allowing only ten 2.5-inch wide storage devices.
Innovation Solution
A high density chassis with two side walls and a carrier tray system that includes dividers to create twelve compartments, allowing for the sliding attachment of a carrier tray by friction, enabling the accommodation of two rows of six storage devices, thus increasing storage capacity by twenty percent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional 1U chassis dimensions are used, then the chassis fits standard server rack specifications, but the storage capacity is limited to ten 2.5-inch storage devices
Solution Approach 1:
The chassis is segmented into multiple compartments using dividers, creating twelve separate storage spaces within the accommodation area. This segmentation allows each compartment to hold a storage device, enabling the chassis to accommodate two rows of six storage devices (12 total) while maintaining the standard 1U external dimensions that ensure compatibility with server racks.
2Quantity of substance
If the chassis size is increased to accommodate more storage devices, then storage capacity increases, but the chassis no longer fits standard server rack dimensions
Solution Approach 1:
The chassis utilizes the depth dimension of the standard 1U form factor more efficiently by implementing a multi-row storage arrangement. Instead of expanding the width or height, the design arranges storage devices in two rows along the depth axis, with dividers creating six compartments per row. This dimensional optimization allows 12 storage devices to be accommodated within the conventional 1U external dimensions (17.7-21.5 inches depth), maintaining server rack compatibility while significantly increasing storage capacity.
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 high density chassis design allows for a twenty percent increase in storage capacity within the same external dimensions as a traditional 1U chassis, accommodating more storage devices without altering the server rack's dimensions.
Implementation Method 1
The carrier tray is slidably attached to each compartment and held in place by friction

AI summary
A removable chassis for a server rack includes two side walls, an accommodation space, and a carrier tray. The two side walls are on either side of the removable chassis, where each side wall includes a slide rail for sliding the removable chassis into or out of the server rack. The accommodation space is defined between the two sidewalls. The accommodation space is divided into a plurality of compartments by a plurality of dividers. The carrier tray is slidably attached to each compartment and held in place by friction. The carrier tray includes at least one recess for each removably receiving an electronic device.
