Magnetic Shielding Raised Floor Panels Using Grain-Oriented Steel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional raised floor panels fail to effectively shield electronic equipment from magnetic fields generated by cables and transformers, leading to equipment malfunction, and existing shielding methods are expensive and inefficient.
Innovation Solution
The use of modular magnetic field shielding raised floor panels made from grain-oriented electrical steel, which are strategically positioned to block magnetic fields by orienting the steel in a direction perpendicular to the magnetic field, combined with a riser and cover plate design that allows for easy access and ventilation, and includes features like sidewalls and lip portions to enhance shielding effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional raised floor panels are used, then the floor structure provides cable space and ventilation, but magnetic fields from cables and transformers cause electronic equipment malfunction
Solution Approach 1:
The patent introduces magnetic shielding lamina as an intermediary material between the magnetic field source (cables/transformers) and the sensitive electronic equipment. This lamina acts as a mediator that blocks and redirects magnetic field lines, preventing them from reaching the equipment while allowing the floor to maintain its structural and ventilation functions.
Solution Approach 2:
The patent employs thin film magnetic shielding lamina that can be integrated into the flexible floor panel structure. These thin films conform to the floor panel geometry and provide continuous magnetic shielding coverage without compromising the flexibility, ventilation, or cable management capabilities of the raised floor system.
2Object-affected harmful factors
If magnetic shielding lamina is wrapped around tools, then minimal magnetic field reduction is achieved, but the process is expensive and time consuming
Solution Approach 1:
The magnetic shielding lamina is pre-integrated into the floor panel structure during manufacturing, rather than being applied later as a separate shielding step. This preliminary incorporation of shielding functionality into the floor panels themselves eliminates the need for time-consuming on-site wrapping of tools and equipment, as the shielding is already in place when the floor is installed.
Solution Approach 2:
The patent combines multiple functions into the floor panel structure: structural support, cable routing, ventilation, and magnetic shielding. By merging the shielding function with the floor panels themselves, the system eliminates the need for separate shielding applications on individual tools and equipment, reducing both time and cost.
3Object-affected harmful factors
If magnetic shielding lamina is wrapped around tools, then some magnetic field protection is provided, but the cables themselves remain unprotected
Solution Approach 1:
The patent divides the shielding solution into segments corresponding to individual floor panels, each containing magnetic shielding lamina. This segmentation allows the shielding to be distributed throughout the entire floor area, providing comprehensive coverage for all equipment and cables across the raised floor system, rather than requiring individual wrapping of each component.
