Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drive systems for synchronous motors with permanent magnets on their circumference suffer from significant losses and inefficient force generation, particularly when the axes of rotation of the discs are aligned identically, leading to force components in directions other than the intended movement.
Innovation Solution
A system comprising a first and second part with cone-shaped discs having permanent magnets on their circumference, where the axes of rotation intersect perpendicularly to the direction of movement, and a sword part between them, allowing for magnetic coupling that generates propulsion force through eddy currents, reducing losses and eliminating the need for additional drive motors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the axes of rotation of the discs are aligned identically, then the structure is simple, but force components arise in directions other than the intended movement and losses increase
Solution Approach 1:
The patent applies asymmetry by orienting the axes of rotation of the two discs at different angles relative to the direction of movement. Specifically, the first disc's axis is oriented at an angle α and the second disc's axis at an angle β, where α ≠ β. This asymmetric arrangement ensures that the magnetic field lines from both discs combine constructively in the direction of movement while canceling out lateral force components, thereby reducing energy losses and improving propulsion efficiency.
2Power
If permanent magnets are placed on the circumference of discs, then propulsion force can be generated through eddy currents, but losses increase when magnets approach the sword part
Solution Approach 1:
The patent applies parameter changes by optimizing the orientation angles of the disc axes (α and β) to control the interaction between the permanent magnets and the sword part. By carefully selecting these angles, the system maximizes the eddy current generation in the sword part for propulsion while minimizing the distance of approach that would cause excessive losses. This parameter optimization allows the system to generate strong propulsion force through eddy currents while keeping energy losses manageable.
3Reliability
If additional drive motors are added to ensure synchronous movement of discs, then synchronous operation is achieved, but device complexity and housing requirements increase
Solution Approach 1:
The patent applies self-service by designing a magnetic coupling mechanism that automatically ensures synchronous rotation of the two discs without requiring additional drive motors. The magnetic coupling connects the discs magnetically, and due to the specific angular orientations of their axes, the magnetic interaction naturally synchronizes their rotation. This self-synchronizing mechanism eliminates the need for complex additional driving devices and housing, while maintaining reliable synchronous operation.
