Rotatable Rack Server Chassis for Compact Storage Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional server systems require elongated casing to accommodate multiple storage devices, leading to increased space occupation and inconvenience during device replacement.
Innovation Solution
A server chassis with a rotatable rack that allows storage devices to be obliquely accessed, reducing the casing length and minimizing space usage by rotating within the casing, while maintaining electrical connections via cord passages and a power supply module positioned for efficient access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If storage devices are arranged side by side in the casing, then the quantity of storage devices can be increased, but the length of the casing needs to be elongated
Solution Approach 1:
The patent applies dimensionality change by transitioning from a linear arrangement of storage devices to a radial arrangement around a central rotating rack. The rack rotates to bring different storage devices into access position, effectively using rotational movement to access multiple devices without extending the casing length linearly.
Solution Approach 2:
The patent implements dynamics by making the storage device rack rotatable rather than static. The rack can rotate to different positions to bring specific storage devices into the access position, allowing dynamic access to multiple devices while maintaining a compact fixed footprint.
2Quantity of substance
If the casing length is elongated to accommodate more storage devices, then the storage capacity is increased, but the space occupied by the server system increases
Solution Approach 1:
The invention changes the spatial arrangement from linear extension to radial distribution around a central rotating rack. This allows multiple storage devices to be accessed by rotation rather than by extending the casing, thereby increasing storage capacity without proportionally increasing the occupied space.
Solution Approach 2:
The storage devices are arranged radially around a central rotating rack, with devices positioned at different angular positions. This nested radial configuration allows multiple devices to be packed into a compact circular footprint rather than requiring linear space.
3Area of stationary object
If storage devices are arranged in a compact configuration, then the space occupied is reduced, but the ease of accessing and replacing devices is worsened
Solution Approach 1:
The rotating rack provides dynamic access to storage devices. When a specific device needs to be accessed or replaced, the rack rotates to bring that device into the access position, making compactly arranged devices easily accessible without requiring the user to reach into deep or crowded spaces.
Solution Approach 2:
The storage devices are segmented into discrete positions on the rotating rack, with each device independently accessible by rotating the rack to the appropriate position. This segmentation allows for easy identification and access of individual devices without disturbing others.

AI summary
A server chassis includes a casing, a motherboard, a rotatable rack and an electronic device. The rotatable rack is axially disposed inside the casing and able to rotate with respect to the casing. The rotatable rack has a plurality of insertion spaces. The electronic device is provided on one side of the rotatable rack, and a cord passage is provided between the fan module and the electronic device. The storage devices accommodated in the rotatable rack is electrically connected to the motherboard via the cord passage, thereby increasing the quantity of the storage devices and decreasing the length of the casing.
