Rack Support Assembly with Sliding Plungers for Toolless Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation and removal of electronic devices fixed in a rack via screws and nuts is time-consuming and requires tools, necessitating a more efficient and toolless method.
Innovation Solution
A support assembly with a slidable component and plungers having guiding ramps, allowing for toolless installation and removal of electronic devices from a rack by sliding the component to disengage or engage with the rack's engagement holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws and nuts are used to fix electronic devices in a rack, then the connection strength is improved, but the installation and removal time increases and tools are required
Solution Approach 1:
The fastening system is segmented into a plunger component with engagement protrusions and corresponding engagement recesses in the rack. This allows the connection to be divided into multiple discrete engagement points that can be quickly engaged and disengaged by sliding the support assembly, eliminating the need for time-consuming screw operations while maintaining strong connections through distributed engagement points
Solution Approach 2:
The support assembly incorporates a slidable component that transitions between locked and unlocked positions. In the locked position, plungers engage with the rack to provide strong fixed connection. In the unlocked position, the plungers can be quickly disengaged for rapid removal. This dynamic mechanism allows the system to switch between strong connection and rapid reconfiguration modes
2Strength
If screws and nuts are used to fix electronic devices in a rack, then the connection strength is improved, but the operation complexity increases due to tool requirements
Solution Approach 1:
The plunger-based engagement system is designed to be self-contained and self-operating. The support assembly includes integrated plungers that automatically engage with the rack when the assembly is inserted and can be easily disengaged by sliding the assembly. This eliminates the need for external tools or complex operations, allowing maintenance personnel to quickly install and remove devices without specialized tools or procedures
Solution Approach 2:
The slidable component provides a dynamic transition between engaged and disengaged states. When the support assembly is slid into the rack, the plungers automatically engage with the engagement recesses to provide strong connection. When needed for removal, the same sliding action quickly disengages the plungers. This dynamic mechanism simplifies operation by using a single intuitive sliding motion for both installation and removal

AI summary
A support assembly is configured to be mounted in a rack. The support assembly includes a support casing and at least one release mechanism. The support casing is formed with at least one hole. The release mechanism includes a slidable component and at least one plunger. The slidable component is slidably disposed on the support casing, the slidable component has at least one slide channel, the plunger is slidably disposed in the slide channel of the slidable component and is inserted into the hole for being engaged with the rack, the plunger has a guiding ramp, and the guiding ramp is configured to resist against an edge of the hole for forcing the plunger to disengage from the rack.
