Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inductor elements face challenges in miniaturization while maintaining high inductance values, as their operating principles are limited to coupling electric current with magnetic energy in a spatial or magnetic material.
Innovation Solution
The inductor elements utilize the interaction between conduction electrons and non-collinear spin structures, such as helical or cycloidal structures, to generate voltage drops and inductance through the deformation of localized spins by emergent electric fields, allowing for miniaturization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional inductor elements use traditional magnetic field coupling principles, then inductance value can be maintained, but device volume must be increased
Solution Approach 1:
The patent replaces the conventional mechanical/electromagnetic field coupling system with a quantum mechanical spin-based system. By utilizing the spin degree of freedom of electrons and their interaction with non-collinear spin structures in metal media, the inductor achieves inductance through quantum spin effects rather than traditional magnetic field coupling, enabling significant volume reduction while maintaining inductance performance
Solution Approach 2:
The patent fundamentally changes the operating parameter from magnetic field strength and geometry to electron spin configuration. By controlling the spin structure (e.g., non-collinear spin arrangements) and applying electric currents that interact with these spin structures, the inductor generates voltage drops through spin-dependent scattering mechanisms, achieving inductance in a compact form factor
2Volume of moving object
If inductor elements are miniaturized using conventional methods, then device size is reduced, but inductance value decreases significantly
Solution Approach 1:
The patent substitutes the conventional size-dependent magnetic field generation mechanism with a quantum spin interaction mechanism. The inductance is generated through the interaction between conduction electrons and localized spin structures, where the spin-dependent scattering creates effective inductance that is not limited by geometric scaling, allowing miniaturization without proportional loss of inductance value
Solution Approach 2:
The patent employs composite metal media containing both conduction electrons and localized spin structures (such as magnetic impurities or spin-active layers). This composite structure enables the coexistence of high electrical conductivity and strong spin scattering effects, achieving high inductance in a miniaturized form by optimizing the interaction between the two components
