Server Chassis Hard Disk Spacing Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
A server chassis with a height of 87 mm can only accommodate seven hard disks due to insufficient spacing, as the remaining 18.72 mm is not enough to fit an eighth disk.
Innovation Solution
The height of the housing is increased from 87 mm to 87.5 mm by reducing the thickness between the substrate and the back plate from 2 mm to 1.2 mm through the use of a fixing portion and fastener, allowing for additional space by increasing the spacing between the hard disks from 18.72 mm to 20.02 mm, enabling the installation of an eighth hard disk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the chassis height is maintained at 87 mm, then the chassis structure remains compact and simple, but only seven hard disks can be accommodated due to insufficient spacing
Solution Approach 1:
The patent changes the thickness parameter of the back plate from conventional dimensions to a reduced thickness, thereby increasing the internal spacing from 18.72 mm to 20.02 mm. This parameter change enables accommodation of eight hard disks while maintaining the original 87 mm chassis height, resolving the contradiction between quantity of hard disks and chassis height.
2Quantity of substance
If the thickness between substrate and back plate is reduced from 2 mm to 1.2 mm, then additional space is created to accommodate more hard disks, but manufacturing precision requirements increase
Solution Approach 1:
The patent specifies a precise thickness reduction from 2 mm to 1.2 mm for the back plate, creating 0.8 mm of additional space. This controlled parameter change enables the installation of an eighth hard disk while establishing new manufacturing precision standards for the chassis assembly, balancing the need for additional capacity with manufacturability.

AI summary
A server chassis includes a housing, a support frame, and a back plate. The housing includes a substrate. A fixing portion is vertically disposed on the substrate and is fixedly connected with the back plate. The support frame is fixedly connected with the substrate. A first protrusion is disposed on the support frame and is inserted into the back plate. The interior of the server chassis is rendered more compact, and the server chassis can accommodate eight hard disks. A server including the server chassis is also disclosed.
