Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data center rack designs are unstable due to vibrations from seismic activity or equipment movement, with existing solutions being complex and expensive.
Innovation Solution
A method and assembly for data center racks that involves stacking racks with vertical columns and attachment brackets to stabilize them, using guiding means for precise alignment, and connecting them with intercolumn connectors for additional stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If racks are stacked one above the other to form rack columns, then space utilization is improved, but stability deteriorates due to vibrations from seismic activity or equipment movement
Solution Approach 1:
The rack column assembly is segmented into multiple independent racks stacked vertically, with each rack being individually stabilizable. This allows the system to achieve high space utilization while maintaining stability through modular construction where each segment can be secured independently.
Solution Approach 2:
Multiple racks are merged into a single rack column assembly by stacking them vertically and securing them together. This combining approach improves space utilization by vertical stacking while the integrated column structure provides enhanced stability against vibrations when properly secured.
2Stability of the object's composition
If dampers are provided along the bases of the racks to reduce vibrations, then stability is improved, but device complexity and cost increase
Solution Approach 1:
The complex damper system is extracted and replaced with a simpler mechanical securing approach. Instead of using active vibration damping components at each rack base, the invention uses passive mechanical connections through vertical columns and attachment brackets that directly prevent relative movement between racks, achieving stability with reduced complexity.
Solution Approach 2:
The invention uses simple, inexpensive mechanical attachment components (brackets and columns) rather than expensive active damping systems. These straightforward mechanical elements provide sufficient vibration resistance without the complexity and cost of sophisticated damper mechanisms.
3Stability of the object's composition
If multiple attachment brackets are used to connect racks to vertical columns, then stability against vibrations is improved, but assembly time increases
Solution Approach 1:
The attachment brackets are designed to be pre-positioned on the vertical columns before rack installation. This preliminary preparation allows for faster assembly as the brackets are already in place to receive the racks, reducing the time required during the actual stacking and securing process while maintaining multiple attachment points for stability.

AI summary
A method for assembling a rack column assembly comprising: positioning a first data center rack on a support surface; stacking a second data center rack atop the first data center rack; placing a first vertical column on a first lateral side of the data center racks; after said stacking, placing a second vertical column on a second lateral side of the data center racks; connecting the first vertical column to the data center racks by fastening first lateral side attachment brackets to the data center racks; and connecting the second vertical column to the data center racks by fastening second lateral side attachment brackets to the data center racks, the first lateral side attachment brackets and the second lateral side attachment brackets limiting movement of the data center racks in a depth direction of the rack column assembly. A rack column assembly is also disclosed.
