Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a USB-C interface is used for charging, then charging capability is improved, but charging speed is insufficient for high-capacity batteries
Solution Approach 1:
The system dynamically switches between USB-C charging mode and DC charging mode based on real-time detection of connected devices and charging requirements. The power switch module can transition from a static single-mode design to a dynamic multi-mode design, adjusting the charging path according to whether a USB device or DC power adapter is connected, thereby optimizing charging speed for high-capacity batteries.
Solution Approach 2:
The data and charging port is designed to support multiple functions: it can serve as a USB data interface, a USB charging port, or a DC charging port depending on the connected device. This multi-functional design allows the single port to replace what would traditionally require separate USB-C and DC charging ports, enabling fast charging when a DC adapter is connected while maintaining USB compatibility.
2Power
If a separate DC charging port is added, then charging speed is improved, but device complexity increases
Solution Approach 1:
The patent combines the USB data interface and DC charging port functions into a single integrated data and charging port. The power switch module selectively connects this single port to different internal components (USB controller or DC charging circuit) based on detection results, merging what would traditionally be separate physical interfaces into one unified port that serves multiple purposes.
Solution Approach 2:
The power switch module acts as an intermediary between the single data and charging port and the internal components. It detects whether a USB device or DC power adapter is connected and routes the port's function accordingly, eliminating the need for separate physical ports while maintaining both USB data transmission and fast charging capabilities.
3Adaptability or versatility
If external adapters are required for data transmission, then interface versatility is improved, but ease of operation deteriorates
Solution Approach 1:
The system performs automatic detection and configuration without requiring user intervention. The detection module automatically identifies whether a USB device or DC power adapter is connected to the data and charging port, and the power switch module automatically configures the appropriate function. This self-service mechanism eliminates the need for users to manually select modes or carry external adapters.
Solution Approach 2:
The system performs preliminary detection of the connected device type before establishing the charging or data transmission path. By detecting the connected device in advance and pre-configuring the appropriate mode, the system avoids the need for users to manually switch between modes or use external adapters, thereby improving ease of operation.
