Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high-voltage low-current charging mode is used to achieve quick charging, then charging speed is improved, but compatibility with widely available 5V-chargers deteriorates
Solution Approach 1:
The patent implements dynamic switching between different charging modes (high-voltage low-current and 5V standard modes) based on the detected charger type. The controller automatically adjusts the charging parameters in real-time, enabling the terminal to adapt its charging strategy according to the connected charger's capabilities, thus resolving the contradiction between achieving quick charging and maintaining compatibility.
Solution Approach 2:
The patent changes the charging parameters (voltage and current) dynamically based on the charger type. When a standard 5V charger is detected, the system operates in 5V mode; when a matching quick charger is detected, the system switches to high-voltage low-current mode. This parameter adaptation allows the terminal to optimize charging speed while maintaining compatibility with different charger types.
2Use of energy by moving object
If matching charger is required to achieve quick charging function, then charging efficiency is improved, but ease of operation deteriorates
Solution Approach 1:
The terminal automatically detects the charger type and self-adjusts its charging mode without requiring user intervention. The controller identifies whether a standard 5V charger or a matching quick charger is connected and automatically switches between charging modes, eliminating the need for users to manually select or configure charging settings, thus improving ease of operation while maintaining charging efficiency.
Solution Approach 2:
The system implements feedback mechanisms to detect the charger's output capabilities and adjusts the charging parameters accordingly. The controller continuously monitors the charger type and provides feedback to the charging circuit, enabling automatic adaptation between 5V mode and high-voltage low-current mode, ensuring both charging efficiency and user convenience.
