Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If multiple antenna devices are assembled into an antenna array to generate sufficient radiation intensity, then radiation intensity is improved, but device size increases
Solution Approach 1:
The antenna device is divided into multiple antenna units arranged in an array, where each unit contains feed lines and radiating elements. This segmentation allows the total radiation intensity to be achieved through collective contribution of multiple smaller units rather than requiring a single large antenna structure.
Solution Approach 2:
The patent transitions from planar feed line arrangements to a three-dimensional structure by introducing vias that connect feed lines across different substrate layers. This vertical dimensionality enables compact routing and reduces the horizontal area occupied by the antenna device while maintaining effective radiating elements.
2Reliability
If conventional antenna designs are used, then manufacturing is simple, but radiation signal quality is insufficient
Solution Approach 1:
The antenna device incorporates switchable antenna units that can be dynamically activated or deactivated based on operational requirements. This dynamic configuration allows the system to optimize radiation signal quality by selectively engaging specific antenna units, while maintaining a compact overall structure through shared feed line infrastructure.
Solution Approach 2:
The patent introduces via structures as intermediary elements that connect feed lines between different substrate layers. These via intermediaries enable efficient electromagnetic coupling and signal transmission, improving radiation signal quality without requiring complex surface-level routing that would increase device footprint.
