Rack Width Adapter Rails for 19-Inch Devices in 21-Inch Racks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rack width adapters for transitioning from 19-inch to 21-inch racks are complex, cumbersome, and result in significant packaging waste when deploying multiple server devices.
Innovation Solution
A multi-device rack width adapter system comprising first and second multi-device rack width adapter subsystems mounted to opposite sides of a rack, with pairs of device coupling elements allowing for the coupling of devices with a smaller width to a larger rack, utilizing snap-fit or toolless engagements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional adapter systems are used to house 19-inch devices in 21-inch racks, then device compatibility is achieved, but device complexity and packaging waste increase significantly
Solution Approach 1:
The patent merges the adapter function with the rack structure by providing rails that are an integral part of the rack assembly rather than separate conversion shelves. The rails are configured to directly receive and secure 19-inch devices within the 21-inch rack, eliminating the need for multiple intermediate conversion components and reducing overall system complexity while maintaining compatibility
Solution Approach 2:
The rack rails are designed to serve multiple functions: they provide structural support for the rack, enable mounting of both 19-inch and 21-inch devices, and eliminate the need for separate conversion adapters. This universal design allows the same rail structure to accommodate different device widths without requiring additional specialized components
2Adaptability or versatility
If conventional adapter systems with conversion shelves are deployed, then 19-inch devices can be housed in 21-inch racks, but packaging waste increases significantly
Solution Approach 1:
The patent extracts the adapter function from the conversion shelf assembly and integrates it directly into the rack rails. By removing the unnecessary conversion shelf intermediate step and using the rack's own structural rails to directly accommodate 19-inch devices, the system reduces material requirements and associated packaging waste while maintaining rack adaptability
3Ease of operation
If multiple conversion shelves and device rail systems are installed, then device coupling is achieved, but installation time and complexity increase
Solution Approach 1:
The patent segments the device coupling function into modular rail units that can be independently installed on the rack. Each rail segment is pre-configured with mounting features and can be quickly attached without requiring complex assembly procedures, reducing installation time while maintaining the ability to couple multiple devices of different sizes

AI summary
A multi-device rack-width-adapted rack system includes a multi-device rack width adapter system mounted to a rack having first and second sides defining a rack housing having a first housing width. The multi-device rack width adapter system includes a first multi-device rack width adapter subsystem in the rack housing mounted to the first side of the rack, a second multi-device rack width adapter subsystem in the rack housing mounted to the second side of the rack, and pairs of device coupling elements each including a first device coupling element on the first multi-device rack width adapter subsystem and a second device coupling element on the second multi-device rack width adapter subsystem. Each pair of device coupling elements may couple a second device to the rack in a second device housing defined by that pair of device coupling elements with a second housing width that is smaller than the first housing width.
