Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional waveguide technology is used to guide electromagnetic waves, then electromagnetic wave guidance is achieved, but specific waveguide conditions must be determined for each different frequency, making the process cumbersome and inefficient
Solution Approach 1:
The patent applies universality by creating a waveguide structure that works across multiple frequency bands (Hz, KHz, MHz, GHz, THz, and optical bands) without requiring frequency-specific condition determination. The dielectric waveguide with specific dimensional relationships and electrode arrays provides universal electromagnetic wave guidance functionality across the entire electromagnetic spectrum, eliminating the need to redesign or recalculate conditions for each frequency.
Solution Approach 2:
The patent utilizes parameter changes by establishing specific dimensional relationships (Formulas 1 and 2) between the waveguide width and height that maintain consistent mode equations across different frequencies. By fixing the dimensional ratios and using electrodes arranged at equal intervals, the system achieves frequency-independent operation through parameter optimization rather than frequency-specific adjustment.
2Reliability
If dielectric solid waveguide is used with specific dimensional formulas, then lateral vibration mode continuity is achieved, but it is troublesome to determine waveguide conditions from Formula 1 or Formula 2 for any different frequency
Solution Approach 1:
The patent achieves universality by designing a waveguide structure where the same dimensional relationships and mode equations apply across all frequency bands. The electrode arrays with equal spacing and the specific width-to-height ratio relationships ensure that the lateral vibration mode continuity is maintained universally, eliminating the need for frequency-specific condition determination while preserving mathematical rigor.
3Adaptability or versatility
If electrodes are arranged at equal intervals in the waveguide, then efficient electromagnetic wave guidance across various frequency bands is achieved, but the structure becomes more complex compared to simple waveguides
Solution Approach 1:
The patent applies segmentation by dividing the waveguide structure into discrete electrode elements arranged at equal intervals along the propagation direction. This segmentation creates a periodic structure that interacts with electromagnetic waves of different frequencies in a predictable manner, enabling broad frequency adaptability. The segmented electrode array replaces what would otherwise require continuous frequency-specific tuning, simplifying the overall system despite the added structural elements.
