Multi-RU Rack Coupling with Moveable Securing Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rack systems face challenges in efficiently and cost-effectively coupling devices of varying Rack Unit (RU) heights to racks, particularly when transitioning from 19-inch to 21-inch widths, leading to complexity, waste, and inefficiency in deployment and maintenance.
Innovation Solution
A multi-rack-unit-device rack coupling subsystem with a base, securing member aperture, and a moveable device securing member that adapts to engage and secure 1RU and multi-RU devices to the rack, allowing seamless integration without the need for multiple rail types.
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 improved, but device complexity and deployment complexity increase significantly
Solution Approach 1:
The rack rail is designed with a universal structure that can accommodate both 19-inch and 21-inch devices directly, eliminating the need for separate adapter systems. The rail includes positioning features that work with standard device ears for both width configurations, allowing a single rail type to serve multiple device compatibility requirements.
Solution Approach 2:
The invention merges the functionality of multiple adapter systems into a single integrated rack rail design. Instead of having separate adapter rails for 19-inch devices and native rails for 21-inch devices, the solution combines both capabilities into one rail structure, simplifying the overall system and reducing deployment complexity.
2Adaptability or versatility
If conventional adapter systems with multiple rail types are used, then device compatibility is improved, but packaging waste increases
Solution Approach 1:
By designing a single universal rack rail that works with both 19-inch and 21-inch devices, the invention eliminates the need to manufacture, package, and ship multiple types of adapter rails. This reduces material consumption and packaging waste associated with maintaining separate adapter systems for different device widths.
3Ease of operation
If static securing hooks are used on rack rails, then device securing is simplified, but multi-RU devices cannot be properly secured when using adjacent 1RU housings
Solution Approach 1:
The invention replaces static securing hooks with moveable securing members that can dynamically adjust their position. The moveable securing member can extend to engage devices positioned in either the first 1RU housing or the second 1RU housing, allowing the same rack rail to securely accommodate both 1RU devices and multi-RU devices without requiring different rail configurations.
4Adaptability or versatility
If multiple rail types are used to accommodate different RU height devices, then device compatibility is improved, but device complexity and deployment time increase
Solution Approach 1:
The rack rail is designed as a universal component that can accommodate devices of varying RU heights (1RU, 2RU, 3RU, 4RU, and higher) using the same rail structure. The moveable securing member can engage with devices at different vertical positions, eliminating the need to install different rail types for different device heights and significantly reducing deployment time.

AI summary
A multi-rack-unit-device rack coupling system includes a rack defining first and second 1RU device housings located immediately adjacent each other. A first multi-rack-unit-device rack coupling subsystem is coupled to the rack adjacent the first 1RU device housing, and includes a first moveable device securing member that engages a multi-RU device to secure the multi-RU device to the rack when the multi-RU device is moved into the first and second 1RU device housings. A second multi-rack-unit-device rack coupling subsystem is coupled to the rack adjacent the second 1RU device housing, and includes a second moveable device securing member that, in response to engagement with the multi-RU device when the multi-RU device is moved into the first and second 1RU device housings, moves in order to allow the multi-RU device to be secured to the rack via the first moveable device securing member on the first multi-rack-unit-device rack coupling subsystem.
