Adaptive Charging Strategy for Multi-Mode Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with multiple operating modes are charged using a single strategy that does not adapt in real time to the actual operating mode, leading to inefficient charging as user requirements for different modes are not met.
Innovation Solution
A charging method that detects the operating mode of an electronic device and adjusts the charging mode accordingly, prioritizing energy storage units based on the detected mode, ensuring that batteries are charged to a saturation state for optimal performance and usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single charging strategy is used for all operating modes, then the charging system is simple and easy to implement, but the charging efficiency and user experience deteriorate because the charging strategy cannot adapt to different operating modes
Solution Approach 1:
The charging strategy dynamically adjusts based on the detected operating mode. The system transitions from a static single charging strategy to a dynamic multi-mode charging strategy that automatically adapts to different operating conditions (tablet mode, notebook mode, charging cable connection status), thereby improving adaptability without requiring complex manual configuration from users.
Solution Approach 2:
The system implements feedback by detecting the current operating mode through sensors and status information, then using this feedback to automatically adjust the charging strategy. The detection unit monitors operating mode changes and provides feedback to the charging control unit, which then selects the appropriate charging strategy, creating a closed-loop adaptive charging system.
2Reliability
If both batteries are charged simultaneously with equal priority, then the charging process is simple, but the reliability of power supply for specific operating modes deteriorates because user requirements for different modes are not met
Solution Approach 1:
The charging system applies local quality by assigning different charging priorities to different energy storage units based on the specific operating mode. In tablet mode, the tablet battery is prioritized; in notebook mode, the base battery is prioritized. This localized differentiation of charging quality ensures reliable power supply for the active operating mode while maintaining manageable control complexity through automated detection and control.
Solution Approach 2:
The system changes the charging parameter (priority level) of different energy storage units based on the detected operating mode. The charging control unit modifies charging parameters dynamically - adjusting which battery receives power first and at what rate - thereby improving power supply reliability for the current operating mode without requiring complex user intervention.
3Ease of operation
If the charging strategy prioritizes the base battery always, then the notebook mode performance is ensured, but the usability of tablet mode deteriorates because the tablet battery may be depleted when detached for separate use
Solution Approach 1:
The charging priority dynamically switches based on the detected operating mode. When in tablet mode or when the tablet is detached, the system dynamically prioritizes charging the tablet battery to ensure usability. When in notebook mode, it dynamically switches to prioritizing the base battery. This dynamic adjustment resolves the contradiction by adapting charging behavior to actual usage scenarios rather than maintaining a fixed priority scheme.
Solution Approach 2:
The system uses feedback from the operating mode detection unit to automatically adjust charging priorities. When the system detects tablet mode operation or tablet detachment, it receives feedback and automatically shifts charging priority to the tablet battery, preventing energy depletion and ensuring usability without requiring manual user configuration.
