Solution Overview

Problem

Current technologies can only achieve total electron transmission through systems without disorder, limiting the application of disordered materials in electronic and optoelectronic devices, as they are assumed to act as insulators due to Anderson localization, whereas ballistic propagation requires no disorder.

Innovation Solution

The development of quantum dragon materials and devices that utilize correlated disorder to achieve total electron transmission without undergoing ballistic propagation, allowing for the creation of disordered systems that function similarly to perfect conductors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If disordered materials are used, then manufacturing flexibility and adaptability improve, but electron transmission deteriorates due to Anderson localization

Engineering Contradiction:

Improvematerial composition flexibilityVSAvoidelectron transmission

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies local quality by creating specific localized structures within the disordered material that facilitate electron transmission. The quantum dragon effect arises from particular local configurations of disorder that, while allowing material flexibility overall, create regions where electrons can propagate with high transmission probability through constructive interference of wavefunctions.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent changes the parameters of disorder correlation in the material system. By tuning the correlation length and strength of disorder, the system transitions from Anderson localization (uncorrelated disorder) to quantum dragon behavior (correlated disorder), maintaining adaptability while improving electron transmission through parameter optimization.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If ballistic propagation is achieved, then electron transmission improves to 100%, but manufacturing precision requirements worsen due to strict control needs

Engineering Contradiction:

Improveelectron transmissionVSAvoiddisorder control precision

Core Design Contradiction:

ReliabilityVSManufacturing precision

Solution Approach 1:

The patent converts the harmful effect of disorder (which normally causes localization) into a beneficial effect. By introducing correlated disorder with specific statistical properties, the system achieves high electron transmission without requiring perfect crystalline order, thus relaxing manufacturing precision requirements while maintaining or improving transmission performance.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

Instead of trying to eliminate disorder to achieve ballistic propagation, the patent inverts the approach by intentionally introducing correlated disorder to achieve the quantum dragon effect. This inversion allows high transmission with relaxed precision requirements, as the disorder itself becomes the mechanism for enhanced transmission rather than the obstacle to be removed.

Inventive Principle:

Principle #13The other way round (Inversion)
