A folding and unfolding assembly with a flexible screen and a support assembly that includes a first antenna group, which changes position to maintain optimal antenna performance by switching between different antenna groups based on signal quality thresholds and user inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal uses a fixed antenna position designed according to initial terminal shape characteristics, then the antenna can provide good antenna performance in the initial configuration, but the antenna performance deteriorates when the terminal structure changes during folding and unfolding operations
Solution Approach 1:
The patent applies the dynamics principle by making the antenna position adjustable rather than fixed. The antenna can dynamically change its position along the support bar according to the terminal's folding/unfolding state, ensuring optimal antenna performance in different configurations. The support bar structure allows the antenna to move from an extended position (when terminal is unfolded) to a retracted position (when terminal is folded), adapting to structural changes while maintaining reliable communication.
2Adaptability or versatility
If the terminal structure changes during folding and unfolding, then the terminal achieves versatility in form factor, but the wireless environment deteriorates leading to poor data transmission and reception
Solution Approach 1:
The patent applies preliminary action by pre-positioning the antenna on the support bar structure, which is designed to automatically move to appropriate positions during folding and unfolding operations. The antenna is preliminarily arranged on the support bar rather than fixed to a specific panel, enabling it to proactively adapt to structural changes. This preliminary positioning strategy ensures that the antenna maintains optimal signal strength and stability across different terminal configurations without requiring complex real-time adjustments.
