Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The directivity of an angle-of-arrival (AOA)-based antenna in electronic devices changes disadvantageously when the flexible display is extended or retracted, affecting the user interface during sharing operations with external devices.
Innovation Solution
An electronic device with a processor, memory, and communication circuitry that determines the position of an external device and displays a sharing interface based on the state of the flexible display, ensuring the AOA antenna's directivity is adjusted accordingly to maintain effective communication and user interaction.

Engineering Contradiction Analysis
1Area of moving object
If the flexible display is extended or retracted to change screen area, then the screen area is increased or decreased, but the directivity of the AOA antenna changes disadvantageously
Solution Approach 1:
The patent applies dynamics by making the antenna system adaptable to different display states. The AOA antenna's directivity is dynamically adjusted based on whether the flexible display is in an extended or retracted state, allowing the antenna to maintain optimal performance across different screen configurations through state-dependent directional adjustment
Solution Approach 2:
The patent changes the operational parameters of the AOA antenna based on the display state. When the flexible display transitions between extended and retracted states, the antenna's directivity parameters are modified accordingly, enabling the system to maintain reliable communication performance despite physical configuration changes
2Adaptability or versatility
If the AOA antenna directivity changes with display extension, then the screen area is flexible, but the positioning accuracy during sharing operations deteriorates
Solution Approach 1:
The patent implements feedback by continuously monitoring the flexible display state and using this information to adjust the AOA antenna's directivity. This closed-loop approach ensures that positioning accuracy is maintained during sharing operations by compensating for directivity changes that occur when the display extends or retracts
Solution Approach 2:
The patent applies preliminary action by pre-adjusting the AOA antenna directivity based on the anticipated display state. Before sharing operations begin, the system configures the antenna's directivity according to the current display configuration, ensuring optimal positioning accuracy is established in advance
