Solution Overview
Problem
Existing magnetic chambers are costly and time-consuming to construct, particularly when requiring complex magnetic field configurations, and there is a lack of efficient methods to confine magnetic fields within vessels of arbitrary shapes.
Innovation Solution
The development of modular coils with grooves that guide current flow to create a magnetic field, allowing for mechanical and electrical joining, and the use of superconducting materials like yttrium barium copper oxide or rare-earth barium copper oxide to form a magnetic chamber that can confine the magnetic field.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a full-sized toroidal fusion device is constructed, then fusion energy gain is achieved, but the device size and cost become prohibitively large
Solution Approach 1:
The patent divides the toroidal fusion device into modular segments that can be assembled together. The magnetic confinement system is segmented into multiple modular coils that can be independently manufactured and then assembled to form the complete toroidal structure, reducing the complexity and cost of building a full-sized device
2Reliability
If conventional non-modular coil designs are used, then magnetic confinement is achieved, but manufacturing complexity and cost increase
Solution Approach 1:
The coil system is divided into multiple identical or near-identical modular units. Each module can be manufactured using standardized processes, allowing for mass production and reduced manufacturing complexity. The modular design enables parallel manufacturing of multiple modules simultaneously
Solution Approach 2:
The modular coil design creates universal components that can be used in different positions within the toroidal device. Each modular coil unit is designed to be interchangeable and can serve the same magnetic confinement function at any location in the torus, simplifying manufacturing and maintenance
3Duration of action of stationary object
If large toroidal devices are built, then fusion reactions are sustained, but construction time and resource allocation increase
Solution Approach 1:
The device is constructed from pre-fabricated modular segments that can be manufactured independently and assembled relatively quickly. This segmentation allows for parallel development and testing of individual modules before final assembly, significantly reducing the overall construction timeline
Solution Approach 2:
Modular components are designed and pre-tested independently before being integrated into the complete device. This preliminary action allows for validation of individual modules in isolation, reducing the risk and time required for full-system commissioning and troubleshooting
