Solution Overview
Problem
In manufacturing industries, particularly in semiconductor fabrication plants, magnetic fields from surrounding sources can interfere with magnetism-sensitive equipment, affecting their operations and performance, as existing solutions fail to effectively shield these tools from diverse magnetic field directions.
Innovation Solution
A board comprising two magnetic conductive plates with perpendicular magnetic directions and a magnetic shielding structure, which concentrates and directs magnetic fields along specific directions while mitigating them in other directions, effectively shielding magnetism-sensitive tools by using materials like silicon steel and aluminum for enhanced magnetic shielding and mechanical protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional single-direction magnetic shielding is used, then shielding in one direction is effective, but shielding against magnetic fields from multiple directions is insufficient
Solution Approach 1:
The patent applies dimensionality change by transitioning from single-direction (one-dimensional) magnetic shielding to multi-directional (three-dimensional) shielding. This is achieved by arranging magnetic conductive plates in multiple orientations (vertical, horizontal, and inclined at various angles) to create a comprehensive shielding structure that addresses magnetic fields coming from different spatial directions, thereby resolving the contradiction between shielding effectiveness and adaptability to diverse magnetic field directions.
Solution Approach 2:
The patent segments the magnetic shielding function into multiple independent magnetic conductive plates positioned at different orientations. Each plate handles shielding in its specific directional orientation, and collectively they provide comprehensive multi-directional protection. This segmentation allows the system to effectively shield against magnetic fields from various directions without requiring a single complex shielding element.
2Object-affected harmful factors
If magnetic shielding structures are added to protect magnetism-sensitive tools, then magnetic field interference is reduced, but device complexity increases
Solution Approach 1:
The patent applies universality by designing magnetic conductive plates that serve multiple functions: they provide magnetic shielding in their respective orientations, structural support, and can be integrated with existing equipment frameworks. This multi-functionality reduces the need for additional dedicated components, thereby minimizing the increase in device complexity while achieving comprehensive magnetic shielding protection.
Solution Approach 2:
The patent merges the magnetic shielding function with the structural framework of the equipment by integrating magnetic conductive plates into the existing support structures and housings. This combination eliminates the need for separate, standalone shielding components, thereby reducing overall device complexity while maintaining effective magnetic field protection.
