Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a larger number of antennas are configured for higher Wi-Fi performance, then Wi-Fi data transmission capability is improved, but power consumption increases and battery life decreases
Solution Approach 1:
The patent implements dynamic antenna configuration where the mobile device adjusts the number of active Wi-Fi antennas based on real-time communication requirements. The system determines the communication type (uplink or downlink dominant) and activates only the necessary number of antennas for that specific scenario, rather than keeping all antennas permanently active. This dynamic adjustment resolves the contradiction by maintaining high data transmission capability when needed while reducing power consumption during low-activity or unidirectional communication periods.
2Productivity
If a larger number of antennas are configured, then Wi-Fi performance is improved, but electromagnetic radiation increases causing potential harm
Solution Approach 1:
The patent applies local quality by differentiating antenna usage based on communication direction and requirement. Instead of uniformly activating all antennas, the system selectively enables specific antennas according to the determined communication type (uplink or downlink). This localized activation ensures that only the minimum necessary antennas are operational at any given time, thereby maintaining Wi-Fi performance while minimizing electromagnetic radiation exposure to users.
3Duration of action of moving object
If a smaller number of antennas are configured for lower power consumption, then battery life is extended, but Wi-Fi data transmission capability decreases
Solution Approach 1:
The system dynamically adjusts antenna configuration based on real-time communication needs. When high data transmission capability is required, the system activates more antennas; when power conservation is prioritized or communication load is low, fewer antennas are activated. This dynamic approach resolves the contradiction by ensuring that battery life is extended during low-activity periods while maintaining adequate Wi-Fi performance when transmission demands arise.
4Use of energy by moving object
If a smaller number of antennas are configured, then power consumption is reduced, but data transmission reliability decreases
Solution Approach 1:
The patent implements dynamic antenna adjustment that responds to communication type determination. When the system identifies uplink or downlink dominant communication, it activates the appropriate number of antennas to ensure reliable data transmission in that direction. This dynamic configuration maintains data transmission reliability by ensuring sufficient antenna resources are available when needed, while reducing power consumption by deactivating unnecessary antennas during periods when full capability is not required.
