Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single antenna system is used, then the device structure is simple, but the performance and operational reliability do not meet requirements
Solution Approach 1:
The antenna system is divided into multiple antenna units (first antenna unit, second antenna unit, third antenna unit, fourth antenna unit) with distinct phase shifting structures and feeding structures. Each antenna unit operates independently at different frequencies, allowing the system to achieve high reliability through diversity while managing complexity through modular design on a shared substrate.
2Reliability
If multiple antenna units operate simultaneously, then signal coverage is improved, but signal interference increases
Solution Approach 1:
Each antenna unit is designed with distinct phase shifting structures (first phase shifting structure, second phase shifting structure, third phase shifting structure, fourth phase shifting structure) that are optimized for specific frequency ranges. The feeding structures are also differentiated to provide localized signal distribution tailored to each antenna unit's operational characteristics, thereby reducing interference while maintaining performance.
3Adaptability or versatility
If multiple antenna units are added, then adaptability to different operating conditions is improved, but space utilization becomes constrained
Solution Approach 1:
Multiple antenna units with different phase shifting and feeding structures are integrated onto a single shared substrate. This merging approach allows the system to support multiple frequency operations and adapt to various operating conditions while efficiently utilizing the available space, avoiding the need for separate substrates or housings for each antenna unit.
4Reliability
If distinct phase shifting structures are used for different frequencies, then frequency-specific performance is improved, but manufacturing complexity increases
Solution Approach 1:
The shared substrate serves multiple functions by supporting all four antenna units, their respective phase shifting structures, and feeding structures simultaneously. This universal platform approach maintains frequency-specific performance for each antenna unit while simplifying manufacturing compared to producing separate assemblies for each frequency, as all components can be fabricated and integrated in a unified process.
