Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional multilayer waveguide structures are used, then waveguide functionality is achieved, but manufacturing complexity and cost increase significantly
Solution Approach 1:
The waveguide structure is divided into separate substrates (first substrate with internal waveguide, second substrate with backshort) connected by an interconnection waveguide. This segmentation allows each substrate to be manufactured independently using standard PCB techniques, avoiding the need for complex multilayer waveguide fabrication while maintaining functional integrity.
Solution Approach 2:
The interconnection waveguide uses an electrically conductive polymer material instead of traditional rigid conductive materials. This parameter change in material properties enables flexible routing and simplifies assembly while maintaining electrical conductivity for microwave signal transmission.
2Reliability
If traditional rigid waveguide structures are used, then structural strength is maintained, but fragility increases and flexibility decreases
Solution Approach 1:
The interconnection waveguide is constructed using an electrically conductive polymer that provides flexibility while maintaining structural integrity. This flexible construction allows the waveguide to accommodate mechanical stress and movement without breaking, improving reliability while enabling easier installation and adaptation to different configurations.
