Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If time division duplex mode is used to prevent interference between radio services, then interference between co-located radios is reduced, but transmission efficiency deteriorates due to poor transmission/reception period arrangement
Solution Approach 1:
The patent implements dynamic transmission/reception period arrangement that adapts to the operational states of multiple radio services. The device dynamically adjusts transmission capable periods and reception capable periods based on real-time conditions, allowing flexible coordination between WLAN, Bluetooth, and other radio services to both prevent interference and maintain high transmission efficiency
Solution Approach 2:
The patent changes the timing parameters of transmission and reception periods for different radio services. By generating first communication information that indicates transmission capable periods and reception capable periods based on second communication information from other networks, the system optimizes parameter configuration to avoid interference while maximizing productivity
2Ease of operation
If transmission/reception periods are not properly coordinated, then communication simplicity is maintained, but signal packet loss increases due to strong transmission interference
Solution Approach 1:
The patent performs preliminary arrangement of transmission capable periods and reception capable periods before actual communication occurs. By generating communication information that pre-coordinates timing between multiple radio services, the system prevents interference proactively, ensuring reliable signal packet reception without complicating the communication process
3Device complexity
If transmission/reception periods are not properly coordinated, then device complexity is reduced, but frame exchange efficiency deteriorates due to acknowledgement transmission failures
Solution Approach 1:
The patent creates a universal coordination mechanism that handles multiple radio services (WLAN, Bluetooth, etc.) through a unified approach. The first communication information structure and generation method work across different service types, providing a multi-functional solution that improves frame exchange efficiency without significantly increasing device complexity
