Solution Overview
Problem
Existing electromagnetic levitation systems face instability in generating magnetic lift for objects, as they either remain stationary or are easily movable but not both, and the use of eddy currents to generate magnetic lift is underdeveloped.
Innovation Solution

Engineering Contradiction Analysis
1Stability of the object's composition
If magnetic repulsion is used to lift an object, then the object can be lifted, but the system becomes either unstable or too stable to move
Solution Approach 1:
The patent applies dynamics by transitioning from static magnetic repulsion to dynamic eddy current generation. The conductive substrate is made movable relative to the magnet array, allowing the system to dynamically generate lift forces through relative motion rather than relying on unstable static magnetic repulsion. This enables the vehicle to achieve both stability during hover and controllability during movement.
Solution Approach 2:
The patent replaces the mechanical magnetic repulsion system with an electromagnetic induction system. Instead of using permanent magnets in direct repulsion, the system uses a magnet array that induces eddy currents in a conductive substrate, creating lift forces through electromagnetic interaction. This substitution provides more stable and controllable lift generation.
2Force
If eddy currents are used to generate magnetic lift, then lift force is generated, but the method is underdeveloped and lacks stability control
Solution Approach 1:
The patent implements feedback control through sensors that detect the vehicle's position and orientation relative to the conductive substrate. The control system processes this information and adjusts the motor's rotation speed and the orientation of the magnet array to maintain stable hover and controlled movement. This closed-loop feedback system ensures reliable stability control for the eddy current-based lift generation.
Solution Approach 2:
The patent controls the magnetic lift force by changing key parameters: the rotation speed of the magnet array (controlled by motor speed) and the orientation angle of the magnet array relative to the conductive substrate. By dynamically adjusting these parameters, the system can generate the required lift force while maintaining stability and enabling controlled movement.

Function Achieved in This Case
Enables stable magnetic lift and propulsion of vehicles, allowing for controlled movement and orientation, addressing the instability issues in existing systems and leveraging eddy currents for efficient force generation.
Implementation Method 1
When a permanent magnet is moved near a conductive object, such as a metal object, eddy currents are established in the conductive object, which generate an opposing magnetic field.
Implementation Method 2
The moving magnets interact with the coils to induce eddy currents in the coils which oppose the flow of current supplied to the coils.
