Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solenoid magnet devices are limited to magnetic fields of around 16 T, which is insufficient for advanced neutron scattering and material studies, and conventional designs restrict the strength of high-field magnets due to robust mechanical structures that obstruct particle observation and require large separations between magnet poles.
Innovation Solution
A solenoid magnet system utilizing a combination of low-temperature superconducting and high-temperature superconducting coils, with axially-inward and axially-outward configurations, and support structures that use magnetic attraction instead of mechanical support to maintain coil positioning, allowing for higher magnetic fields without obstructing the viewing port and enhancing data quality in neutron spectroscopy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If robust mechanical structures are used to support magnet halves, then structural stability is improved, but the viewing port is obstructed and particle observation is restricted
Solution Approach 1:
The patent removes the robust mechanical support structure from the midplane region, extracting the obstruction that blocked the viewing port. The magnet halves are supported at their outer edges rather than across the entire midplane, creating an open central region for unobstructed particle observation while maintaining structural stability through edge support mechanisms.
2Length of moving object
If large separation between magnet poles is maintained, then mechanical support is simplified, but magnetic field strength is reduced
Solution Approach 1:
The patent replaces mechanical support structures with magnetic attraction forces to hold the magnet halves together. This substitution allows the poles to be positioned closer together, increasing magnetic field strength, while the magnetic force itself provides the binding mechanism that would otherwise require mechanical intervention.
3Ease of manufacture
If conventional solenoid magnet design is used, then manufacturing simplicity is maintained, but magnetic field strength is limited to around 16 T
Solution Approach 1:
The patent employs composite magnet design combining different magnetic materials with complementary properties. By integrating materials with different coercivity and remanence characteristics, the system achieves synergistic effects that produce magnetic fields exceeding 16 T while maintaining a manageable structural configuration suitable for neutron scattering facilities.
