Solution Overview
Problem
Conventional power adaptors provide a fixed DC power to electronic devices, leading to unnecessary power loss as they do not adjust output according to the actual power requirements of the device, resulting in inefficient power usage.
Innovation Solution
A smart power adaptor with a power conversion circuit and control unit that communicates through a charging communication protocol to dynamically adjust the DC power output based on the battery module's power state, using different power conversion behaviors to match the device's changing power needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a power adaptor provides a fixed DC power to an electronic device, then the device receives sufficient power for operation, but most of the power becomes meaningless power loss when the device only consumes a small part of the provided power
Solution Approach 1:
The power adaptor dynamically adjusts its output power based on the actual power consumption of the electronic device. The control unit receives feedback about the device's power state and modifies the conversion behavior of the power conversion circuit accordingly, transitioning between different power output levels to match the device's needs rather than providing a fixed power level.
Solution Approach 2:
The system implements a feedback mechanism where the control unit communicates with the electronic device through a charging communication protocol to detect the device's power state. Based on this feedback information, the control unit adjusts the power conversion circuit's operation to optimize power delivery and minimize losses.
2Adaptability or versatility
If a power adaptor provides high power to ensure sufficient supply, then the device operates reliably, but the adaptor cannot adapt to varying power requirements resulting in power waste
Solution Approach 1:
The control unit serves as an intermediary between the power conversion circuit and the electronic device. It manages the communication protocol interactions, interprets the device's power state information, and translates this into appropriate control signals for the power conversion circuit, thereby coordinating the adaptive power supply without requiring complex direct integration between all components.
Solution Approach 2:
The power conversion circuit changes its operating parameters (such as conversion ratio, output current, or output voltage) based on the detected power state of the electronic device. The control unit modifies these parameters dynamically to match the device's actual power requirements, enabling the adaptor to provide high power when needed and reduce power when the device consumes less.
