Server Rack Interior Posts for Tool-less Rail Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing server rack systems face difficulties in efficiently installing and replacing equipment due to obstructions from power and networking cables, and pre-existing tool-less rails often require complex mechanisms and reduce usable volume.
Innovation Solution
The introduction of interior posts within the server frame that do not interfere with standard EIA-310 openings, allowing for easy attachment of additional outer rails and maximizing usable volume by containing end mounting mechanisms inside the frame, enabling simpler and more efficient equipment installation and replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to fix outer rails to the back of server frames, then the mounting structure is secure, but access to the rear of server frames is obstructed by power and networking cables making installation difficult and time-consuming
Solution Approach 1:
The patent introduces an intermediary mounting mechanism consisting of mounting brackets with arms that extend around the front of the server frame. These brackets act as mediators between the outer rails and the server frame, allowing secure attachment without requiring access to the rear of the frame where cables obstruct screw installation. The brackets engage with the server frame from the front, bypassing the cable obstruction problem entirely.
2Ease of operation
If pre-existing tool-less rails are used, then installation is easier, but complex slides, springs, and clips are required increasing device complexity
Solution Approach 1:
The patent extracts and eliminates the complex slides, springs, and clips from the mounting mechanism. Instead of using these complex components, the invention employs simple mounting brackets with arms that can be manually positioned and secured. This extraction of unnecessary complexity maintains ease of installation while dramatically reducing the number of moving parts and mechanical complexities.
3Ease of operation
If pre-existing tool-less rails wrap around the outside of server frame ends, then installation is simplified, but the amount of volume available to the server chassis is reduced
Solution Approach 1:
The patent changes the spatial dimension of the mounting mechanism by positioning the mounting brackets on the front face of the server frame rather than wrapping around the external ends. The arms of the brackets extend horizontally across the front, utilizing the front surface area instead of encroaching on the external volume. This dimensional repositioning preserves maximum usable volume while maintaining ease of installation.

AI summary
An improved server frame for securing equipment thereto. The server frame includes four corner secured between a base and a top. Each corner has a plurality of standard openings to receive ends of a standard rail system used to secure the equipment to the frame. The improvement defined by four interior posts, each has a base plate and an arm plate extending from the base plate. Each interior post is separately secured about the corner post. Each arm plate includes rail apertures. A pair of outer rails secured from the front to the rear of the server frame. Each outer rail has rear and front rear facing hooks configured to allow the outer rail to slide into engagement with the rail apertures on the interior posts, such that the outer rails are configured to receive inner rails secured to equipment for sliding the equipment into the server frame.
