Subassembled Magnetic Levitation Device for Reduced Complexity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing movement devices using magnetic forces for levitation and positioning suffer from high energy losses and complexity, especially when trying to maintain large assemblies in a floating state, and require intricate calculations for magnetic force determination.
Innovation Solution
The movement device subdivides the first assembly into subassemblies with reduced spacing between permanent-magnet arrangements, allowing for simplified magnetic force calculation and efficient levitation, using permanent magnets to reduce waste heat and enable larger assemblies without increased production difficulty, with each subassembly having its own control device for precise position control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the first assembly is made very large, then the magnetic forces for levitation are improved, but the production complexity and calculation complexity increase substantially
Solution Approach 1:
The first assembly is divided into multiple subassemblies (first subassembly, second subassembly, etc.) that are conterminous at boundary lines. Each subassembly contains its own permanent-magnet arrangements with standardized spacing distances. This segmentation allows the overall assembly to be made large while maintaining manageable production complexity through modular construction and simplified calculations based on consistent spacing parameters.
2Force
If the first assembly is made very large, then the magnetic forces for levitation are improved, but the calculation complexity for position control increases substantially
Solution Approach 1:
Each subassembly within the first assembly has permanent-magnet arrangements with identical standardized spacing distances. This local uniformity means that the same calculation methods and parameters can be applied consistently across all subassemblies, regardless of the overall size of the first assembly. The position control calculations are simplified because the magnetic force relationships remain consistent throughout the segmented structure.
3Loss of energy
If permanent magnets are used instead of electromagnets, then energy losses are reduced, but the ability to control magnetic forces dynamically is limited
Solution Approach 1:
The patent uses permanent magnets arranged in specific configurations with standardized spacing distances that can be adjusted or reconfigured. While individual magnets are static, the system achieves dynamic control through the collective arrangement and positioning of multiple permanent-magnet arrangements within subassemblies, maintaining energy efficiency while enabling controlled movement and position adjustment.
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
This configuration enables strong magnetic forces for levitation against gravity, reduces energy losses, and simplifies the calculation of magnetic forces, allowing for larger assemblies to be maintained in a floating state with improved position control and reduced resource requirements.
Implementation Method 1
the magnetic forces are generated by means of permanent magnets... magnetic forces, which are strong enough to hold the two assemblies at a distance, or in the floating state, against the action of gravity
Implementation Method 2
The said spacing distances are preferably used in the course of the position control of the second assembly, in order to calculate the magnetic forces, occurring during operation, between the first and the second assembly

AI summary
A movement device comprising a first and a second assembly, the first assembly being composed of a plurality of subassemblies. Two directly adjacent subassemblies are conterminous with each other at a boundary line. The two subassemblies form at least one first pair of directly adjacent first permanent-magnet arrangements that are separated from each other by the boundary line. The two first permanent-magnet arrangements of the first pair are each arranged with a boundary distance from the boundary line that is reduced with respect to a spacing distance, such that they mutually have the spacing distance. There are present in each case within the said two subassemblies at least one second pair of directly adjacent first permanent-magnet arrangements that mutually have the spacing distance.
