1Productivity

If electrical signals are transmitted at high speed or high frequency to transmit large amounts of data within limited time, then data transmission efficiency is improved, but signal accuracy and strength deteriorate

Engineering Contradiction:

Solution Approach 1:

The patent introduces a wave guiding space as an intermediary structure between signal source and destination. This wave guiding space, formed by stacked dielectric layers with specific dielectric constants, acts as a mediator that enables high-speed electromagnetic wave transmission while maintaining signal integrity through controlled impedance and reduced interference.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the physical parameters of the transmission medium by using dielectric layers with specific dielectric constants (e.g., first dielectric layer with dielectric constant of 3.0-5.0, second dielectric layer with dielectric constant of 4.0-6.0). This parameter optimization enables high-frequency electromagnetic wave propagation while maintaining signal strength and reducing distortion.

Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The patent transitions from planar signal transmission to three-dimensional wave guiding structures by stacking dielectric layers vertically. This dimensional change creates controlled electromagnetic environments that guide waves along specific paths, improving transmission speed and accuracy while organizing complexity in the vertical dimension rather than spreading it horizontally.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent uses composite dielectric structures with different materials having specific dielectric constants. The first dielectric layer (dielectric constant 3.0-5.0) and second dielectric layer (dielectric constant 4.0-6.0) form a composite structure that optimizes electromagnetic wave propagation characteristics, achieving high-speed transmission through material composition rather than complex geometric arrangements.

Inventive Principle:

Solution Approach 1:

The patent specifies optimal parameter ranges for surface roughness (Ra ≤ 100 nm, preferably Ra ≤ 50 nm) rather than requiring extremely tight tolerances. This parameter optimization achieves signal stability through statistically controlled surface properties, balancing manufacturing feasibility with electromagnetic performance by identifying the threshold where surface roughness begins to significantly degrade signal quality.
