Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple antennas are provided for different communication networks, then communication coverage and network support are improved, but path loss and antenna loss vary leading to inefficient signal transmission
Solution Approach 1:
The patent implements dynamic antenna switching between open and closed states based on real-time detection of device folding state and grip conditions. The system transitions from static antenna configuration to dynamic selection, choosing between first antenna (open state) and second antenna (closed state) to optimize signal transmission efficiency for each communication network
Solution Approach 2:
The system changes operational parameters by switching between different antennas based on detected states. When grip is detected in closed state, the system selects the second antenna with different transmission characteristics, effectively changing the signal transmission parameter to adapt to the changed physical state and minimize path loss
2Device complexity
If antenna transmission paths are fixed, then device structure is simple, but path loss cannot be optimized based on device state changes
Solution Approach 1:
The patent incorporates feedback mechanisms where the communication processor continuously monitors device state (folding state and grip detection) and uses this information to determine optimal antenna selection. This closed-loop feedback system ensures reliable signal transmission by adapting antenna configuration to real-time device conditions
Solution Approach 2:
The system performs self-optimization by automatically detecting its own state (open/closed and grip conditions) and independently selecting the appropriate antenna without external intervention. The communication processor uses onboard sensors to monitor device state and autonomously switches antennas to maintain optimal transmission quality
3Device complexity
If single antenna is used, then device complexity is reduced, but communication quality deteriorates due to inability to adapt to different transmission paths
Solution Approach 1:
The patent implements multi-functionality by providing at least two antennas that can serve different communication networks and operational states. The first antenna serves open state and the second antenna serves closed state with grip detection, allowing a single antenna system to handle multiple communication scenarios efficiently
