Chassis Top Cover Riser Cage Support Against Transport Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rackmount servers face issues with top cover deformation during transport due to inadequate support, making it difficult to slide into rack chassis and increasing the risk of damage.
Innovation Solution
A top cover support assembly integrating a sliding bracket with a riser cage and mezzanine card holder, which includes a connection tab and alignment sleeve to secure the top cover and motherboard support tray as a solid assembly, providing structural integrity during transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the top cover is made lightweight for easy handling, then ease of operation is improved, but structural strength deteriorates causing deformation during transport
Solution Approach 1:
The patent combines the top cover support function with the riser cage structure by integrating a sliding bracket that engages with both the top cover connection tab and the riser cage. This merging of functions allows the top cover to be supported by the existing riser cage structure during transport, providing necessary structural strength without adding separate support components that would increase weight.
2Volume of moving object
If the top cover is made large in size to cover more components, then volume is improved, but stability deteriorates making it prone to deformation
Solution Approach 1:
The sliding bracket acts as an intermediary element between the top cover and the riser cage. It provides a mechanical connection point that transfers loads from the large top cover to the structurally sound riser cage, enabling the top cover to maintain its large size for component coverage while gaining the stability needed to resist deformation during transport.
3Strength
If additional support structures are added to prevent deformation, then structural strength is improved, but device complexity increases
Solution Approach 1:
The sliding bracket is designed to serve multiple functions: it provides structural support for the top cover during transport, engages with the riser cage mounting structure, and allows for the attachment of mezzanine cards. By making this single component multi-functional, the patent avoids adding separate support structures, thereby maintaining device complexity at an acceptable level while achieving the necessary structural strength.

AI summary
An information handling system includes a connection tab physically coupled to a top cover of the information handling system, and a sliding bracket configured to engage with a riser cage of the information handling system and the connection tab of the top cover. A mezzanine card holder has an alignment sleeve through which a standoff of a system board of the information handling system may be inserted, such that the standoff may engage with the sliding bracket.
