Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of circular Halbach magnetic ring components is challenging due to magnetic shoe repulsion, leading to inefficient assembly, low precision, and a low qualified rate, as existing methods lack adequate support for maintaining proper alignment and preventing reversal.
Innovation Solution
An assembly process involving sequential adsorption of magnetic shoes on a positioning cylinder, followed by sleeving with a sleeve and an aluminum ring, using anaerobic structural adhesive for secure bonding, ensures close arrangement and prevents reversal, enhancing assembly efficiency and accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If magnetic shoes are assembled one by one in the inner ring of the aluminum ring without magnetic support, then the assembly process is simple, but the magnetic shoes repel each other causing poor arrangement, easy reversal, low efficiency, low precision and low qualified rate
Solution Approach 1:
The patent introduces a positioning cylinder made of magnetic conductive material as an intermediary tool during the assembly process. This positioning cylinder provides magnetic support for the magnetic shoes, ensuring they are closely arranged and properly oriented. The cylinder acts as a temporary mediator that facilitates precise assembly, after which it is removed. This resolves the contradiction by adding a controlled element that enables high precision without permanently complicating the assembly structure.
2Device complexity
If magnetic shoes are assembled without adsorption support, then the assembly equipment is simple, but the magnetic shoes are easily reversed due to repulsive magnetic force
Solution Approach 1:
The positioning cylinder serves as a magnetic intermediary that adsorbs the magnetic shoes during assembly, preventing them from being reversed by repulsive forces. The magnetic conductive material of the cylinder provides stable orientation control without requiring complex equipment. After assembly, the cylinder is removed and the magnetic shoes retain their correct orientation due to the adhesive bonding that was applied during the process.
3Ease of manufacture
If magnetic shoes are assembled without precise positioning, then the assembly process is simple, but the finished product accuracy is low
Solution Approach 1:
The positioning cylinder with its magnetic conductive material serves as a precise positioning intermediary. It provides a controlled magnetic environment that ensures accurate positioning of each magnetic shoe in the correct orientation and location. The cylinder's precise dimensions and magnetic properties enable high measurement precision and finished product accuracy while keeping the assembly process relatively simple through the use of this single specialized tool.
