Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face reduced operational efficiency due to excessive power consumption when connected to multiple external devices, as the total power from the power source is fixed, leading to insufficient current for high-efficiency devices like CPUs and GPUs.
Innovation Solution
A dynamic current control method is implemented using a microprocessor that monitors power consumption and adjusts the current provided to devices, reducing power to low-efficiency devices when consumption exceeds a threshold to reserve current for high-efficiency devices, thereby optimizing power distribution.

Engineering Contradiction Analysis
1Productivity
If the electronic device provides fixed total power to multiple external devices, then all devices can be powered simultaneously, but the operational efficiency of high-efficiency devices (CPU, GPU) decreases due to insufficient current
Solution Approach 1:
The patent implements dynamic current control by continuously monitoring power consumption and adjusting the current provided to external devices in real-time. The microprocessor dynamically determines current allocation based on system power consumption thresholds, transforming the fixed power distribution into a flexible, adaptive system that prioritizes high-efficiency devices when power is constrained.
Solution Approach 2:
The system changes the electrical parameter (current) provided to external devices based on power consumption conditions. When power consumption exceeds thresholds, the microprocessor modifies the current parameter dynamically, reducing it for low-efficiency devices while maintaining or prioritizing current for high-efficiency devices, thereby resolving the contradiction between total power availability and operational efficiency.
2Adaptability or versatility
If the electronic device connects to too many external devices, then connectivity and versatility improve, but power consumption increases beyond available power supply
Solution Approach 1:
The patent employs a feedback mechanism where the microprocessor continuously monitors the total power consumption of the electronic device and uses this information to adjust current allocation to external devices. This closed-loop control ensures that power consumption remains within available supply limits while maintaining connectivity to multiple devices, resolving the contradiction between versatility and energy loss.
Solution Approach 2:
The system performs self-regulation by automatically adjusting current distribution based on monitored power consumption levels without external intervention. The microprocessor autonomously determines when to reduce current to specific devices based on system-wide power conditions, enabling the system to self-manage its power budget while maintaining adaptive connectivity.

AI summary
An electronic device includes a device controller and a microprocessor. The device controller is coupled to a device for controlling the device. The microprocessor is coupled to the device controller. The microprocessor obtains information regarding an amount of power consumption of the electronic device and dynamically determines an amount of current provided to the device according to the amount of power consumption. When the microprocessor determines that the amount of power consumption is greater than a threshold, the microprocessor determines to decrease the amount of current provided to the device.
