Solution Overview

Problem

Conventional magnetizers face limitations in size and orientation performance due to the arrangement of permanent magnets with alternating polarities, leading to inadequate magnetic field coverage and difficulty in maintenance.

Innovation Solution

A magnetizer design featuring a first and second frame member with aligned magnets of opposite polarities, coupled by magnetic force, allowing for increased magnetic field area and easy separation for maintenance, enhancing graphite orientation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If the size of the permanent magnet is increased to improve orientation performance, then the magnetic field coverage is improved, but the magnetization orientation cannot be properly achieved during manufacturing

Engineering Contradiction:
Improvemagnetic field coverage areaVSAvoidmagnetization orientation precision
Core Design Contradiction:
Area of stationary objectVSManufacturing precision

Solution Approach 1:

The patent divides the magnetizer into multiple smaller permanent magnets (first permanent magnets and second permanent magnets) arranged in arrays rather than using a single large magnet. This segmentation allows each small magnet to be manufactured with proper magnetization orientation while collectively providing large magnetic field coverage area through their coordinated arrangement.

Inventive Principle:
Principle #1Segmentation

2Power

If permanent magnets are arranged with alternating polarities, then the magnetic field is generated, but the area with horizontal magnetic field on the coating layer is reduced

Engineering Contradiction:
Improvemagnetic field generationVSAvoidhorizontal magnetic field area
Core Design Contradiction:
PowerVSArea of stationary object

Solution Approach 1:

The patent applies local quality by creating regions with different magnetic field characteristics. The first permanent magnets generate a first magnetic field in a first direction, while the second permanent magnets generate a second magnetic field in a second direction. This local differentiation allows optimization of the magnetic field distribution to increase the horizontal magnetic field area on the coating layer while maintaining overall magnetic field generation.

Inventive Principle:
Principle #3Local quality

3Area of stationary object

If multiple permanent magnets are arranged to increase magnetic field area, then the orientation performance is improved, but the device complexity increases

Engineering Contradiction:
Improvemagnetic field areaVSAvoidmagnet arrangement complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The patent extracts the frame structure into a separate component that provides mechanical support and positioning for the permanent magnets. The frame holds the first permanent magnets and second permanent magnets in predetermined arrangements, simplifying the overall device complexity by separating the structural function from the magnetic field generation function.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A magnetizer may include a first frame member including a first accommodation portion configured to accommodate two or more first magnets arranged along a first direction with a same first polarity, and a second frame member including a second accommodation portion configured to accommodate two or more second magnets arranged with a second polarity different from the first polarity, and configured to maintain a state of being in contact with the first frame member by an attractive force between the two or more first magnets and the two or more second magnets.
