Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity in assembling magnets for a Halbach array arises from the changing direction of magnetic force as each magnet is added, making the process cumbersome.
Innovation Solution
A magnet arrangement method that forms first and second magnet groups with opposing magnetic force directions, allowing these groups to be easily assembled into a Halbach array without changing the direction in which the magnets are held.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If magnets are assembled one by one in a Halbach array, then the magnetic field intensity is maximized in a predetermined direction, but the direction in which each magnet is held changes depending on the orientation of the magnetic poles, causing assembling to become complicated
Solution Approach 1:
The Halbach array is divided into multiple groups, where each group contains magnets with the same magnetic pole orientation. This segmentation allows magnets within each group to be held in a consistent direction during assembly, reducing the complexity caused by constantly changing orientations while still achieving the overall Halbach array configuration that maximizes magnetic field intensity.
2Manufacturing precision
If magnets are assembled one by one with changing orientations, then the Halbach array configuration is achieved, but the process becomes cumbersome and time-consuming
Solution Approach 1:
Magnets are pre-grouped into sets where each group contains magnets with identical magnetic pole orientations. This preliminary action of grouping before assembly allows workers to handle multiple magnets in a consistent orientation, significantly reducing the time required for assembly while maintaining the precise Halbach array configuration through the systematic arrangement of these pre-formed groups.
