Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If waveguide technology with separate modules is used for W-band radar, then high-frequency performance is achieved, but device complexity and volume increase significantly
Solution Approach 1:
The patent combines the waveguide structure, millimeter-wave circuits, and antenna into a single integrated multipolymer circuit board module. The metallization layers serve dual purposes as both waveguide walls and circuit traces, eliminating the need for separate waveguide modules and reducing overall system complexity while maintaining W-band performance
Solution Approach 2:
The metallization layers perform multiple functions simultaneously: they act as waveguide walls for signal transmission, as circuit traces for electrical connections, and as shielding layers for electromagnetic isolation. This multi-functionality reduces the number of components needed and simplifies the overall device structure
2Reliability
If waveguide technology with separate modules is used for W-band radar, then high-frequency performance is achieved, but volume and weight increase
Solution Approach 1:
The millimeter-wave circuits and antenna are embedded within the multipolymer circuit board structure itself. The circuits are positioned between the metallization layers, and the antenna is integrated into the board geometry, creating a compact nested arrangement that significantly reduces volume compared to separate modular components
Solution Approach 2:
The patent merges the waveguide, circuits, and antenna into a single planar circuit board structure. This integration eliminates the need for multiple separate components and their associated mounting hardware, reducing both volume and weight while maintaining W-band operational performance
3Reliability
If waveguide technology with separate modules is used for W-band radar, then high-frequency performance is achieved, but production costs increase
Solution Approach 1:
The patent changes the material parameters by using polymer-based multipolymer circuit boards instead of traditional metallic waveguide materials. This allows the use of standard PCB manufacturing techniques such as lamination and metallization, which are more cost-effective and scalable than precision machining of separate waveguide components
Solution Approach 2:
The patent applies metallization only where needed on the circuit board - specifically as shielding layers and signal-carrying traces - rather than requiring solid metallic construction throughout. This selective metallization reduces material costs and allows for more efficient manufacturing processes
