Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple antennas are placed in proximity for bidirectional communication, then communication functionality is enhanced, but interference between antennas increases
Solution Approach 1:
A ground structure is introduced as an intermediary element positioned between the first and second antennas. This ground structure acts as a mediator that redirects or shields electromagnetic fields, preventing direct interference between the antennas while allowing both to function for bidirectional communication.
Solution Approach 2:
The spatial arrangement segments the electromagnetic field paths between antennas by introducing the ground structure. This segmentation separates the communication paths, allowing multiple antennas to operate in proximity without mutual interference, thus enabling bidirectional communication functionality.
2Productivity
If data transmission rate is increased to handle increasing data amounts, then communication speed improves, but interference and signal quality deteriorate
Solution Approach 1:
The ground structure serves as a mediator that manages electromagnetic field interactions, allowing higher data transmission rates by preventing interference that would otherwise degrade signal quality at increased speeds.
Solution Approach 2:
The ground structure creates localized field management zones around each antenna, improving signal quality in specific regions and enabling higher data transmission rates without widespread interference.
3Area of stationary object
If antennas are placed closer together to reduce device size, then compactness improves, but interference between antennas increases
Solution Approach 1:
The ground structure is positioned between antennas in compact arrangements, acting as a mediator that prevents interference even when antennas are placed closer together, thus enabling smaller device sizes without sacrificing communication performance.
Solution Approach 2:
The ground structure introduces a vertical or lateral dimension to field management, allowing antennas to be placed closer in the horizontal plane without interference, thereby reducing overall device footprint.
