Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a waveguide is formed by stacking a plurality of metal plates, then the radar antenna can transmit and receive signals, but the weight increases
Solution Approach 1:
The patent replaces traditional metal waveguide plates with a composite structure consisting of a plate material (such as plastic or polymer) and a shielding layer (such as conductive coating or metal mesh). This composite structure maintains the waveguide's electromagnetic shielding and signal transmission capabilities while significantly reducing the weight compared to solid metal plates.
2Reliability
If a waveguide is formed by stacking a plurality of plates, then the radar antenna structure is established, but the assembly difficulty increases
Solution Approach 1:
The waveguide structure is divided into multiple plate-shaped components that can be manufactured separately and then assembled by stacking. Each plate includes integrated features such as slots for signal radiation and shielding layers, allowing modular manufacturing and simplified assembly through precise stacking rather than complex fastening operations.
Solution Approach 2:
The patent combines multiple functions into a single plate structure: the plate body provides structural support, slots enable signal radiation, and the shielding layer ensures electromagnetic containment. This integration reduces the number of separate components and simplifies the assembly process while maintaining waveguide functionality.
3Reliability
If plates are stacked to form a waveguide, then the waveguide structure is created, but eccentricity occurs during assembly reducing reliability
Solution Approach 1:
The patent employs design features that ensure uniform contact and alignment between stacked plates, such as precision-machined mating surfaces,定位 features, and symmetric slot arrangements. These features create an equipotential assembly state where plates naturally align without eccentricity, ensuring consistent electromagnetic field distribution and reliable waveguide performance.
