Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a dielectric waveguide-microstrip transition structure is used, then electromagnetic wave transmission is achieved, but the number of components increases and downsizing becomes difficult
Solution Approach 1:
The patent merges the waveguide structure directly with the substrate by forming a through-hole through the substrate to create the waveguide structure, eliminating the need for separate dielectric waveguide blocks, conductor films, spacers, and reflection plates. This integration reduces the number of components while maintaining electromagnetic wave transmission functionality.
Solution Approach 2:
The patent extracts and eliminates unnecessary components from the conventional structure. Specifically, it removes the dielectric waveguide block, conductor film covering, spacers, and reflection plate by reforming the waveguide structure as a through-hole directly in the substrate, thereby simplifying the overall structure.
2Length of stationary object
If a dielectric waveguide-microstrip transition structure with spacer and reflection plate is used, then electromagnetic wave transmission is stable, but the structure size increases
Solution Approach 1:
The waveguide structure is merged with the substrate by forming a through-hole directly through the substrate material. This integration eliminates the need for separate spacers and reflection plates, significantly reducing the overall structure size while maintaining electromagnetic wave transmission stability through the continuous waveguide path.
Solution Approach 2:
The patent transitions from a multi-component three-dimensional assembly to a more compact structure by forming the waveguide as a through-hole that penetrates the substrate in the vertical dimension. This dimensional approach allows electromagnetic wave transmission without requiring additional horizontal space for separate components.
