Removable Lever for Server Rack Tray Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of removing and reinstalling rackmounted equipment in data centers is time-consuming due to complex multi-part levers that are fixed to the devices, requiring an efficient and space-saving solution for easy swapping of hardware components.
Innovation Solution
A removable lever system with a central rotatable structure, long and short arms, and a push arm that rotates about an axis to engage with the chassis module, allowing for easy insertion and removal of computer equipment trays by limiting rotation between inserting and removing positions, and using a magnet for secure attachment to the server rack.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-part levers are used for securing and releasing rackmounted equipment, then the equipment can be firmly secured, but the process becomes time-consuming and complex
Solution Approach 1:
The lever is divided into multiple functional parts: a body portion with a cavity for receiving the tray, a arm portion for engaging the chassis module, and a release mechanism. This segmentation allows each part to perform its specific function efficiently while maintaining overall reliability.
Solution Approach 2:
The lever transitions from a static multi-part design to a dynamic single-piece design that can rotate about an axis. The lever moves between a first position (engaging the chassis module) and a second position (releasing the tray), enabling quick swapping operations while maintaining secure attachment during operation.
2Reliability
If multi-part levers are fixed to the rackmounted computing device, then the equipment can be securely held, but the complexity of the system increases
Solution Approach 1:
Multiple lever components are merged into a single-piece lever structure. The body portion, arm portion, and release mechanism are integrated into one monolithic component, eliminating the need for separate parts while maintaining the security of attachment. This reduces assembly complexity and the number of parts that can fail.
3Reliability
If complex levers are used for equipment swapping, then the equipment can be securely mounted, but the space required for the lever system increases
Solution Approach 1:
The lever design incorporates a cavity within the body portion that receives and nests the tray. This nested structure allows the lever to hold the tray securely within its own structure, minimizing the external volume required while maintaining mounting security. The arm portion extends from the body to engage the chassis module, creating a compact overall form.

AI summary
A removable lever apparatus for inserting and removing computer equipment from a chassis module of a server rack includes a central rotatable structure, a long arm connected to and extending in a first direction away from the central rotatable structure, and a short arm connected to and extending in a second direction away from the central rotatable structure. The central rotatable structure includes a rotation stopper for limiting rotation about the axis of rotation between an inserting position and a removing position. The central rotatable structure also includes a retention structure for maintaining the coupling to the tray when the central rotatable structure is in a position other than the inserting position. The short arm is configured to engage a side wall of the chassis module when the central rotatable structure is rotated.
