Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed charging voltage mode is used, then the charging system is simple to implement, but it cannot adapt to different charger types leading to inefficient charging or heating
Solution Approach 1:
The charging system dynamically switches between different charging modes (first charging mode with first charging voltage and second charging mode with second charging voltage) based on the detected charger type. The processor determines whether to use adaptive charging or non-adaptive charging by analyzing charger characteristics, and adjusts the charging voltage accordingly to optimize charging efficiency and prevent overheating.
Solution Approach 2:
The system changes the charging voltage parameter based on the detected charger type. When an adaptive charger is detected, the system uses a first charging voltage that can reach a first threshold voltage. When a non-adaptive charger is detected, the system switches to a second charging voltage that reaches a second threshold voltage, ensuring safe and efficient charging across different charger types.
2Speed
If high charging voltage is used to achieve fast charging, then charging speed increases, but it causes heating and safety issues when using non-adaptive chargers
Solution Approach 1:
The system dynamically adjusts the charging voltage based on the detected charger type. When a non-adaptive charger is detected, the system automatically switches to the second charging mode with a lower second threshold voltage, preventing excessive heating while maintaining safe charging. When an adaptive charger is detected, the system can utilize the higher first threshold voltage for faster charging without overheating risks.
3Object-affected harmful factors
If the charging voltage is limited to a lower threshold for safety, then heating is reduced, but charging efficiency and speed decrease
Solution Approach 1:
The system changes the charging voltage parameter based on the detected charger type. When an adaptive charger is detected, the system uses a first charging voltage that can reach a first threshold voltage for high-efficiency fast charging. When a non-adaptive charger is detected, the system switches to a second charging voltage that reaches a second threshold voltage, ensuring safe charging without excessive heating. This parameter adaptation resolves the contradiction between safety and charging efficiency.

AI summary
A charging method includes recognizing a type of a charging device in response to being connected to the charging device. The types of the charging devices include an adaptive-type charging device and a non-adaptive-type charging device. A charging mode corresponding to the type of the charging device is determined. Charging modes include at least a first mode and a second mode. A charging voltage of the first mode can reach a first threshold voltage. A charging voltage of the second mode can reach a second threshold voltage. The first threshold voltage is greater than a rated voltage of a battery. The rated voltage is greater than the second threshold voltage. The method includes charging an electronic device according to the determined charging mode.
