1Productivity
If the power adapter improves its performance and functionality to meet higher charging requirements, then the charging efficiency and power supply capability are enhanced, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent implements dynamic power distribution by enabling the electronic device to detect connection states of multiple power adapters and automatically adjust power allocation based on real-time conditions. The system dynamically configures control parameters for charging power chips according to the number and type of connected power supply terminals, allowing the power management system to adapt flexibly to varying charging scenarios without requiring complex hardware redesign
Solution Approach 2:
The patent creates a universal power management system that can handle multiple power supply configurations through a single integrated controller. The control circuit is designed to manage various power adapter types and connection states using unified control logic, enabling the same hardware platform to serve multiple charging functions (single adapter, multiple adapters, different power levels) without requiring separate specialized circuits for each scenario
2Power
If multiple power adapters are connected to meet higher power demands, then the power supply capability is enhanced, but the power management complexity and control difficulty increase
Solution Approach 1:
The patent implements a feedback-based power management system where the control circuit continuously monitors the connection states of power interfaces and the output characteristics of connected power adapters. Based on this feedback information, the system automatically adjusts the control parameters of charging power chips to optimize power distribution. The feedback mechanism enables the system to adapt to changing power supply conditions without manual intervention, simplifying the management of multiple power adapters
Solution Approach 2:
The power management system operates autonomously by automatically detecting the number and type of connected power supply terminals, determining appropriate power distribution strategies, and configuring charging parameters without user intervention. The control circuit self-adjusts power allocation based on real-time connection states, eliminating the need for complex manual configuration or external control mechanisms when connecting multiple power adapters
3Productivity
If the system dynamically adjusts power distribution based on connection states, then the power management efficiency is improved, but the detection and control complexity increase
Solution Approach 1:
The control circuit automatically detects connection states of power interfaces and identifies the number and type of connected power supply terminals without requiring external input or complex user configuration. The system self-monitors the power path and charging parameters, dynamically adjusting power distribution based on detected conditions. This self-service detection approach simplifies the user interface while maintaining high power management efficiency through automatic adaptation to changing connection states
