Engineering Contradiction Analysis
1Loss of time
If conventional interconnect technologies (copper cables or optical components) are used, then communication infrastructure is established, but latency is high, power consumption is high, and cost is high
Solution Approach 1:
The patent replaces conventional electrical signaling through copper wiring with electromagnetic wave propagation through dielectric waveguides. This substitution of transmission mechanism enables millimeter-wave communication with lower latency and power consumption while maintaining signal integrity through the waveguide structure surrounded by dielectric materials.
Solution Approach 2:
The patent changes the operating frequency parameter to millimeter-wave range and modifies the transmission medium properties by using dielectric waveguides with specific permittivity values (first dielectric material with permittivity between 2-10, second dielectric material with different permittivity). These parameter changes enable high data-rate communication with improved performance characteristics.
2Productivity
If dielectric waveguides are used for millimeter-wave communication, then bandwidth density and power efficiency are improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent employs composite dielectric material structures where a first dielectric material surrounds the waveguide opening and a second dielectric material surrounds the first dielectric material. This composite structure provides signal confinement and impedance control while offering manufacturing flexibility, as the layered approach allows for tolerance accumulation management and relaxed individual dimension tolerances compared to single-material waveguides.
