Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies are limited in generating large-scale or high-strength magnetic fields beyond 1 Tesla, which are necessary for applications such as controlling high-energy electron or ion beams, as permanent magnets saturate at 1 Tesla and achieving higher strengths requires large superconducting coils.
Innovation Solution
The apparatus and method involve a plurality of tubes of different dimensions with electrically conductive materials, where each smaller tube is nested within a larger one, and a longitudinal slot is formed to align the magnetic field compression, allowing for the generation of high magnetic flux up to 10 Tesla or higher within an aperture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If permanent magnets are used to generate magnetic fields, then the device is simple and compact, but the magnetic field strength is limited to about 1 Tesla due to saturation
Solution Approach 1:
The patent employs a nested tube structure where multiple conductive tubes are positioned concentrically within each other. Each tube generates a magnetic field component, and through proper current distribution, these fields combine to produce a compressed high-strength magnetic field in the central aperture region, achieving over 10 Tesla while maintaining a compact configuration.
Solution Approach 2:
The invention transitions from using permanent magnets (which saturate at 1T) to an active electromagnetic field generation system using multiple conductive tubes. By arranging tubes in a multi-dimensional nested configuration and controlling current flow through each tube, the system creates a compressed magnetic field in the central aperture that achieves strengths exceeding 10 Tesla.
2Strength
If superconducting coils are used to generate high magnetic fields of 10 Tesla or higher, then the magnetic field strength is sufficient, but the device becomes large and complex
Solution Approach 1:
The patent uses a nested arrangement of multiple conductive tubes where each tube contributes to the overall magnetic field. This configuration allows the system to generate high magnetic fields (10T or higher) in a compact volume by distributing the field generation across multiple smaller tubes rather than requiring a single large superconducting coil.
Solution Approach 2:
The magnetic field generation is divided into multiple segments, each produced by a separate conductive tube. By segmenting the field generation task across multiple tubes with different dimensions and positions, the system achieves high magnetic field strength in the central aperture while keeping each individual tube relatively small and manageable.
3Strength
If large coils are used to generate high magnetic fields, then the magnetic field strength is sufficient, but the volume required becomes excessively large
Solution Approach 1:
The nested tube configuration allows multiple field-generating elements to occupy overlapping spatial regions. This nesting enables the system to produce high magnetic fields (10T or higher) in a compact volume by having tubes of different sizes concentrically arranged, with the magnetic fields combining in the central aperture region.
Solution Approach 2:
The invention uses a multi-dimensional nested tube structure where tubes are arranged concentrically along a common axis. This spatial arrangement in multiple dimensions allows the system to concentrate magnetic field generation in the central aperture volume, achieving high field strength without requiring a large overall device volume.

AI summary
An apparatus for magnetic field compression includes a plurality of tubes of different dimensions. Each smaller tube extends within a larger tube and each tube includes an electrically conductive material for generating a magnetic field in response to electric current flowing in the conductive material. A longitudinal slot is formed in each tube. The longitudinal slot in each tube is aligned to form an aperture in which the magnetic field is compressed or has a highest magnetic flux in the aperture in response to the electric current flowing in the conductive material of each tube.
