Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive bonded tiles or resin flooring are used, then static charge dissipation is achieved, but the flooring system is damaged or loosened under heavy point loads requiring time-consuming and expensive repairs
Solution Approach 1:
The patent replaces the mechanical adhesive bonding system with a magnetic field-based holding system. The magnetic floor tiles contain magnetic layers that interact with a magnetically receptive underlayment, creating a non-contact holding mechanism that eliminates mechanical stress and damage to the flooring system while maintaining secure attachment for static charge dissipation functionality.
2Ease of operation
If loose-lay/interlocking tiles are used, then portability is improved, but the tiles shift under weight loads and fail to re-align correctly resulting in impaired connectivity of the conductive system
Solution Approach 1:
The patent replaces the mechanical interlocking system with a magnetic field-based alignment system. The magnetic attraction between the magnetic floor tiles and the magnetically receptive underlayment provides automatic alignment and positioning, ensuring that the conductive ground plane maintains continuous connectivity while preserving the ability to easily remove and reposition tiles for portability.
3Ease of operation
If magnetic floor tiles are used, then easy removal and repositioning is achieved, but the magnetic forces must be strong enough to hold tiles securely under heavy loads
Solution Approach 1:
The patent utilizes parameter changes in the magnetic system by employing magnetic layers with specific remanence values (0.10-0.50 Tesla) and varying tile thicknesses (0.2-1.0 mm) to optimize the magnetic holding force. The magnetic force is sufficient to secure tiles under heavy point loads while remaining manageable for easy removal and repositioning operations.
