Seismic Kit Bracket and Clamp Design for Data Center Cabinet Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data center cabinets in seismic zones require secure fastening to withstand significant forces, but existing solutions lack simplicity and flexibility in installation and deflection control during seismic events.
Innovation Solution
A seismic kit comprising a bracket with a first and second member, where the second member is secured to the cabinet frame and the first member to the floor, along with leveling leg clamps that stabilize the cabinet by securing around its leveling legs, providing additional bracing to prevent excessive deflection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cabinet is secured to the floor in a seismic zone, then the cabinet can withstand significant seismic forces, but the installation becomes more complex and time-consuming
Solution Approach 1:
The seismic kit is divided into separate components: a bracket assembly that attaches to the cabinet frame and leveling leg clamps that secure the leveling legs. This segmentation allows for easier installation and replacement without requiring complete disassembly of the cabinet mounting system.
Solution Approach 2:
The bracket is pre-attached to the cabinet frame before installation, and the leveling leg clamps are designed to be quickly secured around the leveling legs. This preliminary preparation reduces on-site installation time and complexity while ensuring proper seismic reinforcement.
2Reliability
If a cabinet is secured to the floor in a seismic zone, then the cabinet can withstand significant seismic forces, but the installation time increases
Solution Approach 1:
The seismic kit is divided into separate components: a bracket assembly that attaches to the cabinet frame and leveling leg clamps that secure the leveling legs. This segmentation allows for easier installation and replacement without requiring complete disassembly of the cabinet mounting system.
Solution Approach 2:
The bracket is pre-attached to the cabinet frame before installation, and the leveling leg clamps are designed to be quickly secured around the leveling legs. This preliminary preparation reduces on-site installation time and complexity while ensuring proper seismic reinforcement.
3Reliability
If existing seismic solutions are used, then the cabinet can be secured, but flexibility in installation and deflection control is insufficient
Solution Approach 1:
The leveling leg clamps are designed to be adjustable and removable, allowing the cabinet to maintain proper leveling while providing controlled deflection during seismic events. The clamps can be positioned at different locations along the leveling legs to accommodate various cabinet configurations and floor conditions.
Solution Approach 2:
The bracket design incorporates multiple attachment points and configuration options that can accommodate different cabinet frame sizes and types. The same seismic kit can be used across various cabinet models, providing universal seismic protection while maintaining installation flexibility.

AI summary
A cabinet installed in a data center is secured to the floor in the data center by a seismic kit to eliminate excessive deflection of the cabinet during a seismic event. The seismic kit includes a bracket and leveling leg clamps. The bracket is secured to the cabinet frame. The bracket has a first member and a second member with the second member extending upwards from the first member. The leveling leg clamps are secured to the first member of the bracket. The leveling leg clamps have a rectangular member with a cutout to receive leveling legs of the cabinet.
