Foldable Battery Sharing Control for Wireless Device Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery sharing technologies in electronic devices require manual user intervention for enabling and disabling battery sharing, and power supply can be disrupted if the external device is not accurately detected within the charging area or if the device is tilted, leading to inefficiencies and potential damage.
Innovation Solution
An electronic device with a foldable display and multiple housings, equipped with wireless power transmission/reception circuits, automatically controls battery sharing based on the folding state and device detection, allowing seamless power supply and information management through integrated display areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual user intervention is required to enable and disable battery sharing, then user control over battery sharing is achieved, but operation convenience deteriorates
Solution Approach 1:
The system automatically detects the external device and activates battery sharing without requiring manual user intervention. The electronic device monitors the charging area, identifies when an external device is placed, and autonomously initiates power transmission, thereby improving operation convenience while eliminating complex manual control steps
Solution Approach 2:
The system continuously monitors the charging area for external devices and provides real-time feedback detection. When an external device is detected in the charging area, the system automatically responds by enabling battery sharing. This feedback mechanism allows the system to self-adjust based on device presence, eliminating the need for manual enable/disable operations
2Reliability
If automatic device detection is implemented, then power supply reliability is improved, but detection precision requirements increase
Solution Approach 1:
The charging area is divided into multiple detection zones with different sensitivity levels. The system segments the detection space to identify whether an external device is present in the optimal charging position, reducing the complexity of precise detection while maintaining reliable power supply activation
Solution Approach 2:
The system uses a broader detection range and multiple detection methods beyond the minimum required precision. By implementing excessive detection coverage with various sensors and detection algorithms, the system ensures reliable device detection without requiring extremely precise single-point detection, thereby improving reliability while managing detection complexity
3Productivity
If the electronic device supplies power while tilted or upside down, then power transmission functionality is maintained, but harmful effects increase
Solution Approach 1:
The system dynamically adjusts the power transmission parameters based on the detected orientation of the electronic device. When the device is in an optimal orientation, full power transmission is enabled. When tilted or upside down, the system automatically reduces or stops power transmission to prevent harmful effects, while maintaining the ability to resume normal operation when properly oriented
Solution Approach 2:
The system performs preliminary detection of device orientation before initiating full power transmission. By detecting the orientation state in advance and preventing power transmission when the device is tilted or upside down, the system avoids harmful effects before they can occur, while still maintaining productivity when properly oriented
