Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional electromagnetic materials are used, then the material structure is simple, but the electromagnetic properties are limited to natural ranges
Solution Approach 1:
The electromagnetic material is segmented into multiple layers with different orientations of artificial microstructures. Each layer contains microstructures oriented in specific directions, allowing independent control of electromagnetic properties in different spatial dimensions. This segmentation enables tuning of dielectric constant and magnetic permeability separately along different axes.
Solution Approach 2:
The patent employs composite material structure combining multiple types of artificial microstructures (cross-shaped, spiral, rectangular) with different geometric parameters embedded in a substrate. By combining microstructures with varying shapes, sizes, and orientations across multiple layers, the material achieves extraordinary electromagnetic properties that cannot be obtained with single-structure conventional materials.
2Adaptability or versatility
If artificial microstructures with complex geometric configurations are introduced, then extraordinary electromagnetic properties are achieved, but the manufacturing complexity increases
Solution Approach 1:
The patent extracts the essential electromagnetic functionality from complex three-dimensional structures by using two-dimensional planar microstructures (cross-shaped, spiral, rectangular patterns) that can be fabricated using standard PCB or lithography techniques. This extraction maintains the extraordinary electromagnetic properties while dramatically simplifying manufacturing compared to volumetric metamaterial structures.
Solution Approach 2:
The patent achieves tuning of electromagnetic properties by varying geometric parameters of the microstructures including line width, spacing between elements, size of cross-arms or spiral arms, and orientation angles. These parameter changes allow continuous adjustment of dielectric constant and magnetic permeability without changing the fundamental structure type, facilitating ease of manufacture through parameter optimization rather than structural redesign.
