An electronic device with a USB type-C connector that includes multiple ground pins for different frequency bands, allowing selective connection to a multiband antenna without additional connectors, enabling wireless communication services across various bands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-band antenna is connected through a shared ground port of an analog audio connector, then the connector structure is simple, but the wireless communication service quality for multiple bands is degraded
Solution Approach 1:
The ground port is segmented into multiple independent ground pins (first ground pin and second ground pin), each dedicated to specific frequency bands. This segmentation allows the connector to support multiple frequency bands simultaneously without signal interference, resolving the contradiction between simple structure and multi-band service quality
Solution Approach 2:
The connector is designed with universal multi-functionality by incorporating multiple ground pins that can serve different frequency bands (e.g., band 3, UHF, L band) through a single connector interface. This enables the analog audio connector to support multiple bands without requiring separate connectors for each band, maintaining structural simplicity while enhancing service quality
2Adaptability or versatility
If an antenna supporting only one band or intermediate band is used, then the connector compatibility is maintained, but the DVB service quality across multiple bands is degraded
Solution Approach 1:
The connector employs dynamic pin assignment where the first ground pin and second ground pin can be selectively activated based on the frequency band requirements. This dynamic configuration allows the connector to adapt to different antenna types (single-band or multi-band) while maintaining optimal service quality for the selected band, balancing compatibility and service quality
3Reliability
If multiple ground pins for different frequency bands are implemented, then the wireless communication service quality across multiple bands is improved, but the connector complexity increases
Solution Approach 1:
Multiple ground pins for different frequency bands are merged into a single connector housing, integrating what would otherwise require separate connectors. This merging approach provides multi-band support with enhanced service quality while minimizing the increase in overall connector complexity through unified design
