Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hermetic window is used at the waveguide opening to achieve hermeticity, then hermeticity is improved, but device complexity and cost increase
Solution Approach 1:
The patent removes the hermetic window component entirely by extracting the hermetic sealing function from the waveguide opening and relocating it to the coaxial connector interface. The coaxial connector itself serves as the hermetic barrier, eliminating the need for additional hermetic windows and reducing structural complexity.
Solution Approach 2:
The coaxial connector is designed to serve multiple functions simultaneously: it provides the transition between microstrip and waveguide propagations, ensures hermetic sealing, and enables direct signal transfer. This multi-functionality eliminates the need for separate hermetic window components.
2Reliability
If a cabling component is used to link the coaxial connector and microwave module, then hermeticity is improved, but performance degrades due to noise and power loss
Solution Approach 1:
The patent merges the coaxial connector and microwave module into a single integrated structure where the conductive pin directly connects the microstrip line to the waveguide. This eliminates the cabling component and reduces signal path length, minimizing noise and power loss while maintaining hermeticity through the integrated design.
Solution Approach 2:
The conductive pin serves as an intermediary element that directly transfers signals from the microstrip line to the waveguide without requiring external cabling. This internal conductive connection eliminates the performance-degrading cabling component while maintaining hermetic sealing.
