Load-Spreading System for Computer Cabinet Raised Floors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ground anchoring systems for computer cabinets in data centers face challenges with increased weight, leading to stress concentrations on raised floors and limited accessibility for additional anchoring points, especially when cabinets have non-standard widths, causing invalidating stress on modern building structures.
Innovation Solution
A removable mechanical structure with 5 beams, made from aluminium extrusion profiles, is placed between the cabinet floor and the ground, distributing load more evenly and closer to the most rigid zones of the raised floor, using pins and cap screws for secure assembly and load transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If plunger cylinders are used for ground anchoring, then the cabinet is stable and load is transmitted to the raised floor, but the ground anchoring area is very small causing punching of raised floor slabs when cabinet weight increases
Solution Approach 1:
The invention divides the load transmission function from the cabinet floor to the raised floor by introducing an intermediate load distribution structure. This structure segments the concentrated load from plunger cylinders into distributed loads across multiple contact points on the raised floor, preventing slab punching while maintaining cabinet stability.
Solution Approach 2:
The load distribution structure acts as an intermediary between the cabinet and the raised floor. It receives the cabinet weight and redistributes it to the raised floor at optimized locations, mediating the force transmission to avoid excessive stress on individual floor slabs.
2Force
If plunger cylinders are placed in cabinet corners, then load is transmitted to the raised floor, but when cabinets have non-standard widths the stress concentrations are shifted outside the most rigid zones of the raised floor
Solution Approach 1:
The load distribution structure implements local quality by providing different load transmission characteristics at different locations. It concentrates loads at specific points corresponding to the most rigid zones of the raised floor (typically where floor panels are supported by structural elements), rather than uniformly distributing or corner-based loading.
3Strength
If the number of plunger cylinders is increased to improve load distribution, then load spreading improves, but accessibility for installation becomes difficult or impossible due to cabinet arrangement in rows
Solution Approach 1:
The invention merges multiple plunger cylinders into a single integrated load distribution structure. This unified structure provides the load distribution capability of multiple anchoring points while being accessible from the front or rear of the cabinet, eliminating the need to access side areas between cabinets in rows.
4Device complexity
If conventional plunger cylinders are used, then the system is simple to implement, but the ground anchoring area is very small requiring very strong increase in slab resistance
Solution Approach 1:
The load distribution structure segments the load transmission path and distributes forces across multiple locations on the raised floor, increasing the effective ground anchoring area without significantly increasing system complexity. The modular design allows for straightforward installation.

AI summary
A device for spreading the floor-loading of a computer cabinet includes a bottom, an external face of which is to be positioned facing the floor. The external face of the bottom of the cabinet includes pins, each pin including at its end furthest from the bottom a head the diameter of which is greater than the diameter of a shank of the pin, the shank providing the connection between the cabinet and the pin, the load-spreading device includes at least two beams, each beam including at least two parallel flat faces: a first face includes a slot acting as a rail, the width of the slot being greater than the diameter of a pin shank but less than the diameter of a pin head, this slot collaborating with at least two pins for the installation of the beam, a second face is in contact with the floor.
