Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If traditional structures are used in electromagnetic systems, then the system structure is simple, but energy loss increases by up to 20% or more due to wave blocking

Engineering Contradiction:
Improveenergy lossVSAvoidstructure complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The metasurface is segmented into multiple layers with distinct functional elements (wave refractors, combiners, splitters) arranged in specific patterns. Each layer performs a specific function in the wave manipulation sequence, allowing complex wave control to be achieved through modular, systematic segmentation rather than a monolithic structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The multilayer metasurface acts as an intermediary device placed between the electromagnetic wave source and the obstructive structure. It mediates the interaction by refracting, combining, and splitting waves to guide them around the obstruction, preventing direct blocking while maintaining system simplicity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If multilayer metasurface devices are used to reroute electromagnetic waves, then energy loss is reduced, but the device complexity increases

Engineering Contradiction:
Improveenergy outputVSAvoidmetasurface structure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The metasurface device integrates multiple functions (wave refraction, combination, and splitting) into a single multilayer structure. The same basic geometric pattern is used across different layers, but with varying orientations and positions to achieve multiple functions, reducing the need for entirely different structures for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The device uses composite structures combining conductive materials (copper, aluminum, gold, or silver) with dielectric materials (such as those with permittivity values of 2.2, 3.0, or 4.4). This composite approach enables simultaneous control of wave refraction and combination/splitting functions through material properties rather than purely geometric complexity.

Inventive Principle:
Principle #40Composite materials

3Ease of manufacture

If wave blocking structures are present, then manufacturing is simpler, but energy distribution becomes non-uniform

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidenergy distribution uniformity
Core Design Contradiction:
Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The metasurface employs local variations in geometric pattern orientation and positioning across different layers. Specific regions have patterns oriented at different angles (e.g., 0°, 45°, 90°, 135°) to locally control wave behavior, achieving uniform overall energy distribution through localized adjustments rather than uniform structure throughout.

Inventive Principle:
Principle #3Local quality

AI summary

A system that allows for electromagnetic energy to be “re-routed” around normally occlusive structures. The system comprises a first multilayer metasurface device and a second multilayer metasurface device. The first multilayer metasurface device has a plurality of wave refractors fabricated on a first metasurface and a plurality of wave combiners fabricated on a second metasurface. The second multilayer metasurface device has a plurality of wave splitters fabricated on a first metasurface and a plurality of wave refractors fabricated on a second metasurface. The occlusive structures are disposed between the first multilayer metasurface device and the second multilayer metasurface device such that energy is re-routed around the occlusive structures.
