Two-Piece Center Wall Structure to Prevent Chassis Carrier Sagging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information handling system carriers often sag or bow due to unsupported centers, causing mechanical interference and potential damage.
Innovation Solution
A two-piece center wall design for the carrier, comprising a structural member with a continuous top surface and a hem, mechanically coupled to a tray, providing structural support and minimizing sagging and bowing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single-piece center wall is used in the carrier base, then the manufacturing process is simpler, but the structural stiffness and resistance to sagging/bowing is insufficient
Solution Approach 1:
The center wall is divided into two separate pieces: a structural member and an accessory member. The structural member provides the necessary stiffness and support to prevent sagging and bowing, while the accessory member can be configured for different accessory types. This segmentation allows each piece to be optimized for its specific function, with the structural member forming rigid triangles with the tray sides to maximize structural strength.
2Adaptability or versatility
If the center wall is designed to support multiple accessory types, then the adaptability increases, but the structural integrity may be compromised
Solution Approach 1:
The center wall is segmented into a structural member and an accessory member. The structural member maintains consistent geometry and rigidity to preserve structural integrity, while the accessory member can be configured differently to accommodate various accessory types such as optical drives, floppy drives, or blank spaces.
Solution Approach 2:
The accessory member is designed to be universal, capable of supporting multiple types of accessories through different configurations. This allows the same basic carrier structure to adapt to different information handling resources while the structural member continues to provide consistent structural support.
3Device complexity
If the carrier base is supported only at the rails, then the device complexity is reduced, but the carrier base sags and bows causing mechanical interference
Solution Approach 1:
The center wall is divided into a structural member that forms rigid triangular support structures with the sides of the tray, and an accessory member. This segmentation creates additional structural support points in the center of the carrier base, preventing sagging and bowing while maintaining relatively simple device complexity.

AI summary
An information handling system may include one or more information handling resources and a carrier for housing the one or more information handling resources. The carrier may include a carrier cover and a carrier base mechanically coupled to the carrier cover. The carrier base may include a tray configured to mechanically couple to the one or more information handling resources and a wall. The wall may include a structural member mechanically coupled to the tray, the structural member comprising a continuous top surface having an uninterrupted geometry and a hem along the continuous top surface and an accessory member mechanically coupled to the structural member and extending above the continuous top surface.
