Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional magnetic suspension devices are unstable and prone to wobbling due to fluctuations in the magnetic field generated by electromagnets, especially under environmental conditions like air flow and environmental electromagnetism, and are not easily adaptable for non-spherical suspension members.
Innovation Solution
A magnetic suspension device with at least two first and second magnetic action units arranged in intervals, where the second units interact with the first units to stabilize the suspension member, using a combination of permanent magnets and electromagnets with adjustable magnetic strength controlled by a sensing member and circuit, allowing for stable suspension and rotation with minimal friction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single electromagnet is used to generate the magnetic field for suspension, then the device structure is simple, but the magnetic field is unstable and the suspension member wobbles easily under environmental conditions
Solution Approach 1:
The patent divides the magnetic field generation into multiple independent electromagnets (at least two) arranged in interval and corresponding to each other. Each electromagnet independently contributes to the overall magnetic field, providing redundancy and stability. This segmentation allows the system to maintain stable suspension even if environmental conditions fluctuate, as the distributed magnetic field configuration reduces sensitivity to local disturbances.
2Device complexity
If a conventional single-point magnetic suspension is used, then the device is simple, but it cannot stably suspend non-spherical objects
Solution Approach 1:
The patent transitions from a single-point or single-axis magnetic suspension to a multi-point, multi-dimensional magnetic field configuration. By arranging at least two electromagnets in interval and corresponding to each other, the system creates a distributed magnetic field that can interact with multiple second magnetic action units on the suspension member. This dimensional expansion enables stable suspension of non-spherical objects by providing balanced magnetic forces across different spatial locations.
3Ease of operation
If magnetic suspension is used to reduce friction, then movement smoothness is improved, but stability is compromised due to magnetic field fluctuations
Solution Approach 1:
The patent incorporates a sensing member (such as a Hall sensor) and a control circuit that form a closed-loop feedback system. The sensing member detects the position and orientation of the suspension member in real-time, and the control circuit adjusts the current to the electromagnets accordingly to maintain stable suspension. This feedback mechanism compensates for magnetic field fluctuations and environmental disturbances, ensuring both movement smoothness and suspension stability.
