Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the antenna operating band is shifted to a higher frequency, then the communication capability is improved, but the radiation coverage is decreased
Solution Approach 1:
The antenna is divided into multiple antenna units with different sizes (first antenna units with larger area and second antenna units with smaller area). Each antenna unit resonates at different frequency bands, allowing the antenna device to operate across multiple frequency bands simultaneously while maintaining adequate radiation coverage at each frequency.
Solution Approach 2:
Different regions of the antenna structure are designed with different properties - larger antenna units for lower frequency bands and smaller antenna units for higher frequency bands. This local differentiation allows each region to be optimized for its specific frequency range, improving overall multi-band performance.
2Adaptability or versatility
If an antenna structure capable of operating a plurality of frequency bands is implemented, then the communication versatility is improved, but the device complexity increases
Solution Approach 1:
Multiple antenna units with different sizes are integrated into a single antenna device structure. These antenna units are disposed in an alternating pattern and connected to a feeding line, combining multiple frequency band capabilities into one unified antenna system rather than using separate antennas for each frequency band.
Solution Approach 2:
The antenna device is designed to perform multiple functions - it can operate across multiple frequency bands (e.g., low band, mid band, high band) simultaneously using the same physical structure. The alternating pattern of different-sized antenna units enables universal coverage across diverse frequency ranges.
3Weight of stationary object
If the display device is made thinner and light-weighted, then the portability is improved, but the space for accommodating the antenna is decreased
Solution Approach 1:
The antenna units are arranged in an alternating pattern that efficiently utilizes the available space on the display device surface. By optimizing the spatial distribution and dimensional arrangement of antenna units with different sizes, the design maximizes antenna functionality within the limited space available in thin, lightweight display devices.
