Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional antennas are added to support multiple wireless communication functions (WLAN, WWAN, GPS, satellite communication), then communication coverage and functionality are improved, but device space is consumed and antenna isolation becomes difficult to maintain
Solution Approach 1:
The patent applies universality by enabling a single antenna to serve multiple wireless communication functions (WLAN, WWAN, GPS, and satellite communication) through a switch module that dynamically connects the antenna to different communication modules based on signal requirements. This allows one antenna structure to replace what would traditionally require multiple separate antennas, thereby saving device space while maintaining comprehensive wireless communication functionality.
2Adaptability or versatility
If additional antennas are added to support multiple wireless communication functions, then communication coverage is improved, but antenna isolation becomes difficult to maintain leading to signal interference
Solution Approach 1:
The patent applies dynamics by implementing a switch module that dynamically connects the shared antenna to different communication modules based on real-time signal requirements. The switch module activates only the necessary communication module at any given time, preventing simultaneous operation of multiple antennas and thereby eliminating signal interference while maintaining comprehensive communication coverage across different environments.
3Adaptability or versatility
If satellite communication module is added to extend network coverage to remote areas, then network coverage is improved, but additional antenna space is required
Solution Approach 1:
The patent applies universality by designing a shared antenna system where a single antenna structure serves both terrestrial wireless communication (WLAN, WWAN) and satellite communication functions. The switch module intelligently routes signals between these different communication modes, allowing the device to extend network coverage to remote areas with satellite communication capability without requiring separate dedicated antenna space for satellite functionality.
4Reliability
If multiple antennas are used for wireless network and satellite communication, then signal transmission quality is improved, but device complexity increases
Solution Approach 1:
The patent applies dynamics by implementing a switch module that dynamically manages antenna connections based on communication requirements. Instead of maintaining multiple permanently connected antenna systems, the switch module activates only the necessary communication pathway at any given time, thereby maintaining signal transmission quality for both wireless network and satellite communication while reducing the overall structural complexity of the antenna system.

AI summary
A wireless communication system includes at least one first antenna, a wireless network module, a satellite communication module, and a switch module. In the wireless communication system, one end of the switch module is connected to the first antenna, the other end is connected to the wireless network module and the satellite communication module, and the switch module selectively switches electrical connection of the wireless network module or the satellite communication module to the first antenna. When there is a wireless radio frequency signal, the switch module selectively turns on the first antenna and the wireless network module. When there is no wireless radio frequency signal, the switch module selectively turns on the first antenna and the satellite communication module.
