Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices struggle to create non-ergodic systems for guiding charge carriers like electrons due to stringent requirements such as ideal parallel boundaries and perpendicular reflections, making it difficult to achieve desired motion and conductivity patterns.
Innovation Solution
A device featuring a two-dimensional electron gas or thin superconducting layer with a curved or angled main path, where a magnetic field guides carriers along the main path, resulting in asymmetrical conductivity and allowing for the generation of electrical voltage and power from thermal energy or electromagnetic noise.

Engineering Contradiction Analysis
1Stability of the object's composition
If ideal parallel boundaries and perpendicular reflections are used to create a non-ergodic system, then the desired motion pattern is achieved, but the device complexity and manufacturing difficulty increase significantly
Solution Approach 1:
The patent applies curvature by using a spherical or curved surface geometry for the electron gas confinement structure. This curved geometry naturally creates the non-ergodic motion patterns through geometric constraints rather than requiring ideal parallel boundaries with perfect reflections. The curvature radius is specifically chosen to be comparable to or smaller than the electron mean free path, creating the desired directional conductivity while maintaining manufacturing feasibility.
2Use of energy by moving object
If the layer thickness is reduced to the order of magnitude of the mean free path length, then the desired electron guidance effect is achieved, but the manufacturing precision requirements become extremely stringent
Solution Approach 1:
The patent changes the geometric parameters of the system, specifically using a curved surface with radius R where R ≤ λ (mean free path). This parameter relationship creates the non-ergodic system without requiring ultra-thin layers. The curvature radius and mean free path are the key parameters that are optimized to achieve the desired effect while avoiding extreme manufacturing precision requirements.
3Ease of operation
If a magnetic field is used to guide carriers along a curved path, then asymmetrical conductivity is achieved, but the device complexity increases due to additional field generating components
Solution Approach 1:
The patent introduces asymmetry through the combination of curved geometry and magnetic field. The curved path with radius R ≤ λ creates asymmetric electron trajectories, and the magnetic field further enhances this asymmetry by causing Lorentz force deflection. This asymmetric configuration results in different conductivity in different directions, achieving the desired directional guidance effect.
