Server Chassis Movable Bracket for Accurate Expansion Assembly Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In high-height server chassis, the assembly of connector assemblies is hindered by the side plate, making it difficult to mount components accurately and efficiently.
Innovation Solution
A server chassis design with a movable mounting bracket system that allows the expansion assembly to be mounted outside the side plate's obstruction, using a fixed bracket and a movably disposed mounting bracket with elastic components for easy alignment and attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the server chassis has a high height of 2U or more with the side plate structure, then the motherboard and power distribution plate can be disposed on different heights, but the side plate blocks and hides components during assembly, making it difficult to mount the connector assembly accurately and quickly
Solution Approach 1:
The mounting bracket is designed to be movable relative to the side plate, allowing it to protrude outward during assembly operations. This dynamic configuration enables operators to access and mount components accurately without the side plate blocking the view, while maintaining the high-height chassis structure for proper component separation.
Solution Approach 2:
The mounting system is divided into separate components: the side plate remains fixed as part of the chassis structure, while the mounting bracket is a separate movable component that can be positioned independently. This segmentation allows the side plate to maintain structural integrity while the mounting bracket provides unobstructed access for assembly operations.
2Device complexity
If the mounting bracket is fixed inside the chassis, then the structure is simple, but the expansion assembly cannot be mounted accurately due to the side plate blocking the view and access
Solution Approach 1:
The mounting bracket transitions from a static fixed position to a dynamic movable position that protrudes outward during assembly. This allows the bracket to maintain a simple integrated structure when retracted, while providing accurate mounting capability when extended, resolving the conflict between structural simplicity and mounting precision.
Solution Approach 2:
The mounting bracket is designed to move in the vertical dimension, protruding outward from the side plate during assembly operations. This dimensional movement allows the bracket to access mounting positions that would otherwise be blocked, improving mounting accuracy without adding complex horizontal or rotational mechanisms.
3Manufacturing precision
If the mounting bracket protrudes out of the top side continuously, then the expansion assembly can be mounted accurately, but the structure becomes more complex and may interfere with other components like the top plate
Solution Approach 1:
The mounting bracket employs a movable design that allows it to protrude outward only when needed for assembly operations, and retract when not in use. This dynamic behavior provides mounting accuracy on demand while minimizing structural complexity and avoiding interference with the top plate during normal operation.
Solution Approach 2:
The mounting bracket has different functional states: when protruding, it provides accurate mounting capability; when retracted, it maintains a compact profile. This local quality variation allows the same component to serve different functions at different times, achieving precision when needed while maintaining simplicity otherwise.

AI summary
A server and a server chassis. The server chassis configured for an expansion assembly to be mounted thereon and including a housing and at least one mounting assembly. The housing includes a bottom plate, a first side plate and a second side plate. The first side plate and the second side plate are respectively connected to two opposite sides of the bottom plate. The first side plate has a top side facing away from the bottom plate. The at least one mounting assembly includes a fixed bracket and a mounting bracket. The fixed bracket is fixed to the first side plate. The mounting bracket is configured for the expansion assembly to be mounted thereon and movably disposed on the fixed bracket.
