Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the dielectric substrates are positioned in a conventional aligned manner, then the structural integrity and electromagnetic performance are maintained, but the wire connection to radiators becomes difficult and manufacturing complexity increases
Solution Approach 1:
The patent introduces a longitudinal dimension offset between the first and second dielectric substrates. The first substrate is positioned at a first longitudinal location while the second substrate is positioned at a second longitudinal location, creating a staggered three-dimensional arrangement. This dimensional change allows wires to connect to radiators from the side rather than requiring penetration through stacked substrates, significantly easing manufacturing while maintaining electromagnetic performance.
2Ease of operation
If the radiators are fully enclosed within the dielectric substrates, then the electromagnetic shielding and performance are optimized, but the connection points for external wire access become inaccessible
Solution Approach 1:
The patent uses the longitudinal separation between substrates as an intermediary spatial arrangement. By positioning substrates at different longitudinal locations rather than stacking them directly, the design creates accessible side connections for wires while maintaining the enclosed radiator structure. This intermediary positioning allows external wire access without compromising the electromagnetic shielding provided by the dielectric substrates.
