Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If fast charging technology is used to improve charging speed, then charging time is reduced, but charging safety cannot be ensured due to lack of communication channel for parameter control
Solution Approach 1:
The patent implements a communication channel between charging adapter and terminal that enables bidirectional feedback. The charging adapter can send charging parameters and receive status information from the terminal, allowing real-time monitoring and adjustment of charging processes to ensure safety while maintaining fast charging performance
Solution Approach 2:
The patent introduces a communication protocol as an intermediary mechanism that mediates between the charging adapter and terminal. This protocol establishes a controlled interaction channel that allows parameter negotiation and safety verification without compromising charging speed
2Reliability
If communication channel is established between terminal and charging adapter for refined control, then charging safety is improved, but device complexity increases
Solution Approach 1:
The patent utilizes existing USB communication interfaces (D+, D- lines) for the communication channel, making the system multi-functional. These existing pins are used both for data communication and charging control, avoiding the need for additional dedicated communication hardware and reducing overall system complexity
Solution Approach 2:
The communication protocol is designed to be automatically negotiated and established between the charging adapter and terminal without requiring complex external configuration or intervention. The system self-configures the communication channel using existing interface standards, reducing the burden on users and simplifying deployment
