Variable-depth multi device chassis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-device chassis systems for information handling systems (IHS) face inefficiencies in accommodating devices of varying depths, leading to wasted space in racks due to the need for separate chassis for half-width, full-depth and half-width, half-depth devices, resulting in unused slots when an odd number of these devices are installed.
Innovation Solution
A multi-device coupling system with adjustable device stop members that allow for the secure positioning and removal of devices of different depths within a single chassis, enabling side-by-side orientation and efficient use of rack space by accommodating half-width, full-depth and half-width, half-depth devices in a single slot configuration.

Engineering Contradiction Analysis
1Reliability
If separate multi-device chassis are used for different device configurations (half-width full-depth vs. half-width half-depth), then device security and proper positioning are ensured, but rack space is wasted and chassis complexity increases
Solution Approach 1:
The chassis is designed with a single standardized configuration that can accommodate both half-width full-depth devices and half-width half-depth devices through adjustable stop members. This universal design eliminates the need for multiple specialized chassis types, allowing the same chassis to serve multiple device configuration needs while maximizing rack space utilization.
Solution Approach 2:
The stop members are made adjustable rather than fixed, allowing their positions to be dynamically changed to match different device depth requirements. This dynamic adjustment capability enables the chassis to adapt to various device configurations without requiring separate fixed designs for each scenario.
2Manufacturing precision
If separate multi-device chassis are used for different device configurations, then proper device positioning is achieved, but the number of chassis components and system complexity increase
Solution Approach 1:
Instead of manufacturing multiple specialized chassis variants for different device configurations, a single universal chassis design is used with adjustable stop members. This reduces manufacturing complexity and inventory requirements while maintaining precise positioning capability through the adjustable mechanism.
Solution Approach 2:
The positioning system is segmented into adjustable stop members that can be independently positioned, rather than requiring a completely different chassis design for each device type. This segmentation allows precise positioning to be achieved through component adjustment rather than through complex overall chassis design variations.
3Stability of the object's composition
If fixed stop members are used in multi-device chassis, then device positioning is stable, but adaptability to different device depths is reduced
Solution Approach 1:
The stop members transition from fixed to adjustable, allowing their positions to be changed based on device depth requirements. This dynamic capability maintains positioning stability during device installation and operation while providing adaptability to accommodate different device configurations through simple adjustment of the stop member locations.

AI summary
A multi device system includes a rack with a rack slot. A device chassis is positioned in the rack slot. The device chassis includes first device slot with a first device entrance, and a second device slot with a second device entrance. A first device stop member extends from the device chassis and into the first device slot. The distance between the first device stop member and the first device entrance is adjustable, and the first device stop member is configured to move a first device in the first device slot through the first device entrance. A second device stop member extends from the device chassis and into the second device slot. The distance between the second device stop member and the second device entrance is adjustable, and the second device stop member is configured to move a second device in the second device slot through the second device entrance.
