Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a transmission port integrates both data transmission and charging functions, then the device size is reduced, but the port cannot perform both functions simultaneously reducing data transmission efficiency and charging efficiency
Solution Approach 1:
The patent implements dynamic function switching at the transmission port by detecting the connection state of external devices and automatically adjusting the port's operational mode. The control unit receives detection signals from the transmission port, determines the connected device type, and dynamically switches between data transmission mode and charging mode, enabling the port to adapt its function in real-time based on connection status
Solution Approach 2:
The transmission port is designed with multi-functionality to support both data transmission and charging operations. By integrating a switching power circuit and control unit, the port can universally handle different operational requirements - serving as a data port when connected to data devices and as a charging port when connected to power devices, thus achieving true multi-functional capability in a single port
2Loss of information
If the transmission port is used for data transmission, then data communication is enabled, but charging function cannot be executed simultaneously reducing charging efficiency
Solution Approach 1:
The system employs feedback mechanisms where the control unit continuously monitors detection signals from the transmission port's detecting pin. Based on this feedback information about the connected external device, the control unit intelligently determines whether to enable data transmission mode or charging mode, and switches the switching power circuit accordingly, ensuring optimal performance based on real-time connection status
3Use of energy by moving object
If the transmission port is used for charging, then charging function is enabled, but data transmission cannot be executed simultaneously reducing data transmission efficiency
Solution Approach 1:
The transmission port implements dynamic functional adaptation by detecting the type of connected external device and automatically switching between charging mode and data transmission mode. The control unit processes detection signals and dynamically reconfigures the switching power circuit to enable the appropriate function based on real-time connection status, allowing the port to be charging-oriented when needed and data-oriented when needed
