Solution Overview
Problem
Current transportation systems using magnetic levitation face challenges in achieving efficient levitation and reducing friction, as existing technologies often result in incomplete magnetic flux paths that do not effectively counteract gravity and increase weight, leading to reduced levitative forces.
Innovation Solution
A tubular magnetic bearing structure with a source of magnetic flux and a focusing source, combined with a control system using coils and sensors, to optimize magnetic flux paths and maintain horizontal position, enhancing levitative force and reducing weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If existing magnetic levitation technologies are used, then levitation can be achieved, but the magnetic flux paths are incomplete which reduces levitative forces and increases weight
Solution Approach 1:
The magnetic bearing structure is divided into multiple functional segments: a tubular structure with first and second structures providing horizontal magnetic flux paths, a third structure providing vertical magnetic flux path, and a fourth structure completing the flux path. This segmentation creates complete closed-loop magnetic flux paths that improve levitative force efficiency.
Solution Approach 2:
The invention extends the magnetic flux paths into multiple spatial dimensions by adding horizontal structures (first, second, and fourth structures) in addition to the vertical third structure. This multi-dimensional arrangement creates complete closed-loop flux paths that were incomplete in conventional single-dimension designs, thereby increasing levitative force.
2Force
If magnetic flux paths are extended to improve levitation, then levitative force increases, but device complexity increases
Solution Approach 1:
Multiple magnetic flux path functions are merged into a single integrated tubular structure containing the first, second, third, and fourth structures. This consolidation achieves complete closed-loop flux paths while reducing the number of separate components compared to implementing each flux path as an independent structure.
Solution Approach 2:
The tubular magnetic bearing structure serves multiple functions simultaneously: the first and second structures provide horizontal flux paths for levitation, the third structure provides vertical flux path for load support, and the fourth structure completes the flux path. This multi-functionality reduces overall system complexity.
