Engineering Contradiction Analysis
1Reliability
If antenna positions and configurations are fixed based on fully-expanded or fully-closed states, then device structure is simple and easy to manufacture, but antenna operating efficiency and communication performance are reduced during folding
Solution Approach 1:
The patent applies dynamics by making the antenna configuration adjustable rather than fixed. The antenna operating state is dynamically changed based on the folding angle detection, allowing the system to adapt to different structural states (fully-expanded, partially-folded, fully-closed) and maintain optimal communication performance throughout the folding process.
Solution Approach 2:
The patent changes the antenna operating parameters (such as resonance frequency, impedance matching) based on the folding angle. By detecting the folding angle and adjusting corresponding antenna parameters, the system maintains optimal antenna performance across different device configurations without requiring complex mechanical antenna structures.
2Productivity
If antenna configurations are optimized for only fully-expanded or fully-closed states, then device complexity is reduced, but service data throughput and OTA performance are greatly reduced during folding process
Solution Approach 1:
The patent implements feedback by detecting the folding angle and using this information to adjust the antenna operating state. The system continuously monitors the device state and makes real-time adjustments to antenna parameters, ensuring optimal communication performance and service data throughput throughout the folding process.
Solution Approach 2:
The patent applies preliminary action by pre-configuring multiple antenna operating states corresponding to different folding angles. The system prepares these states in advance and switches between them based on detected folding conditions, enabling rapid adaptation without complex real-time calculations during communication operations.
3Reliability
If antenna positions are fixed, then manufacturing precision requirements are simplified, but orthogonality characteristics of antennas change during folding leading to low operating efficiency
Solution Approach 1:
The patent changes antenna operating parameters (such as resonant frequency, impedance) based on folding angle to maintain optimal orthogonality characteristics. This approach preserves antenna performance during folding without requiring complex mechanical adjustments to antenna positions or orientations.
