Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In coating facilities, magnetic systems with Helmholtz coils pose challenges during frontloading due to protrusion, obstructing the loading and unloading process, and existing solutions either compromise magnetic field distribution or require complex and costly coil designs with movable parts.
Innovation Solution
A Helmholtz coil pair is formed by two adjacent coil sections, where one section is electrically decoupled and can be mechanically moved, allowing for a compact configuration that maintains magnetic field effectiveness without obstructing the loading process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a Helmholtz coil pair is used to generate homogeneous magnetic field in the coating chamber, then the magnetic field distribution is improved, but the lower coil protrudes and obstructs the loading and unloading process
Solution Approach 1:
The lower coil is divided into two adjacent coil sections that can be independently positioned. This segmentation allows one section to be tilted away during loading/unloading operations while the other remains in place, resolving the contradiction between maintaining magnetic field effectiveness and enabling unobstructed access.
Solution Approach 2:
The coil sections are made mechanically movable relative to each other, allowing dynamic reconfiguration. During normal operation, the sections form a complete circular coil for optimal magnetic field generation. During loading/unloading, one section can be tilted away to clear the access path, and then returned to position afterward.
2Ease of operation
If the lower coil is made movable to avoid obstructing loading process, then the ease of operation is improved, but the device complexity and maintenance cost increase
Solution Approach 1:
By dividing the coil into two independent sections with a simple mechanical connection, the complexity is distributed and managed more easily than a fully movable single coil. Each section can be independently supported and controlled, simplifying the overall mechanical design.
Solution Approach 2:
Only one coil section needs to be made movable rather than the entire coil assembly. This partial action approach achieves the operational requirement of clearing the loading path without requiring complex mechanisms to move the complete coil structure.
3Ease of operation
If a small lower coil is used to avoid obstructing loading, then the ease of operation is improved, but the magnetic field distribution becomes suboptimal
Solution Approach 1:
The coil sections dynamically adjust their configuration based on operational needs. During loading/unloading, they form a compact arrangement that clears the access path. During coating operations, they are positioned to form a complete circular Helmholtz coil pair, restoring optimal magnetic field distribution.
Solution Approach 2:
The coil sections can be tilted away from the horizontal plane, utilizing the vertical dimension to clear the loading path without reducing the horizontal footprint. This dimensional transition allows the coil to maintain its full diameter for magnetic field generation while avoiding obstruction during operations.
