Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If complex coils are used to provide propulsion in magnetic propulsion systems, then propulsion force is generated, but device complexity and energy consumption increase
Solution Approach 1:
The patent extracts and eliminates the complex coil system from the magnetic propulsion system. Instead of using electromagnets with coils, the invention uses permanent magnets arranged in a Halbach array configuration, thereby removing the need for complex energized coils while maintaining propulsion functionality through eddy current induction in the reaction plate
Solution Approach 2:
The patent replaces the electromagnetic coil system with a permanent magnet system that utilizes eddy currents induced in a conducting reaction plate. This substitution eliminates the mechanical complexity of coil windings, insulation, and electrical connections while achieving propulsion through electromagnetic induction in the reaction plate
2Ease of operation
If electromagnets are used in the track assembly, then propulsion can be controlled, but energy consumption and system complexity increase
Solution Approach 1:
The patent implements a self-service mechanism where the moving vessel generates its own propulsion through eddy currents induced in its reaction plate as it passes the permanent magnets. The system does not require external energy input to the track or magnets, as the kinetic energy of the moving vessel itself is converted into propulsive force through electromagnetic induction
Solution Approach 2:
The patent inverts the conventional approach by placing permanent magnets on the stationary track and using the motion of the vessel to generate propulsion, rather than using electromagnets on the track to push a passive vessel. The control is achieved by modulating the vessel's own motion and magnetic field interaction, rather than externally controlling the track
3Use of energy by moving object
If permanent magnets are used instead of electromagnets, then energy efficiency improves, but magnetic field control capability decreases
Solution Approach 1:
The patent introduces dynamic control elements in the form of movable or adjustable permanent magnets, and/or controllable reaction plates that can modify their magnetic properties or geometry during operation. This allows the static permanent magnets to achieve dynamic field control capabilities, enabling acceleration, deceleration, and directional control without requiring electromagnets
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system achieves efficient propulsion and centering without electrical power, reducing energy consumption and complexity, enabling high-speed operation with minimal moving parts and no physical contact between the guideway and the moving object.
Implementation Method 1
Electrical currents can be generated by the system via relative motion of the magnets and reaction plate, which are also known as 'eddy currents.'
Implementation Method 2
These currents may generate magnetic fields which will repel the reaction plate from the magnets, thereby applying a thrust force and a centering force on the vessel assembly
Implementation Method 3
The track assembly preferably includes a plurality of permanent magnets.
Implementation Method 4
These currents may generate magnetic fields which will repel the reaction plate from the magnets
