Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If differential strip conductor lines are used for non-contacting data transmission, then data transmission is achieved, but bandwidth is limited and bit error rate increases at higher data rates
Solution Approach 1:
The dielectric waveguide is divided into multiple segments of equal length, with each segment terminated at its far end. This segmentation reduces signal reflections and interference, enabling higher data transmission rates with lower bit error rates while maintaining reliable signal integrity across the rotating interface.
Solution Approach 2:
The patent replaces the mechanical differential strip conductor line system with a dielectric waveguide system that uses electromagnetic wave propagation through dielectric material. This substitution eliminates the limitations of conventional electrical contacts, enabling wider bandwidth and higher data rates without increasing bit error rates.
2Productivity
If higher data rates are transmitted using conventional methods, then productivity increases, but susceptibility to interference increases
Solution Approach 1:
A dielectric waveguide serves as an intermediary medium between the transmitting and receiving components. This dielectric medium guides electromagnetic signals with minimal interference from external sources, allowing high-speed data transmission while protecting against electromagnetic interference and stray radiation that would otherwise affect conventional transmission methods.
3Productivity
If conventional strip conductor lines are used, then data transmission is achieved, but stray radiation increases
Solution Approach 1:
The patent confines electromagnetic energy within the dielectric waveguide structure, converting what would otherwise be stray radiation into useful guided waves. The dielectric material and waveguide geometry work together to contain and direct electromagnetic energy, reducing stray radiation while maintaining effective data transmission capability.
