Problem
When multiple adapters with different rated powers are connected to an electronic device, the device primarily uses the adapter with the highest output voltage, leading to potential overloading and limited utilization of other adapters.
Innovation Solution
A power allocating system where each adapter includes a processor that communicates with a controller in the electronic device to calculate and adjust output utilization rates, ensuring that all adapters are used efficiently and equally based on demand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple adapters with different rated powers are connected in parallel to an electronic device, then the electronic device can meet different power requirements, but the device will primarily load the adapter with the highest output voltage, causing other adapters to be underutilized and the highest voltage adapter to be overloaded
Solution Approach 1:
The controller calculates the output utilization rate of each adapter based on rated information and current output information, then transmits adjusting signals back to the adapters to modify their output. This closed-loop feedback mechanism enables dynamic power distribution that prevents overloading of high-voltage adapters while ensuring full utilization of all connected adapters, thereby resolving the imbalance problem without compromising power flexibility
2Quantity of substance
If multiple adapters are provided in parallel, then different power requirements can be met, but the adapters are limited to use under the same power due to the electronic device loading only the highest output voltage adapter
Solution Approach 1:
The system dynamically adjusts the output power of each adapter based on real-time utilization calculations. The controller continuously monitors rated information and current output information, computes utilization rates, and sends adjusting signals to optimize power distribution. This dynamic control enables all adapters to contribute effectively to meeting the electronic device's power requirements, transforming static parallel connection into an actively managed power distribution system that maximizes the productivity of each adapter
