Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different manufacturers use different communication protocols for writing interaction devices, then each manufacturer can optimize performance for their specific device, but compatibility across different devices and electronic devices deteriorates
Solution Approach 1:
The patent implements a universal charging protocol that can identify and adapt to different communication protocols (USB Type-C, USB Type-A, wireless charging) used by various writing interaction devices. The electronic device performs protocol detection and automatic adaptation, allowing a single electronic device to work with multiple types of writing interaction devices from different manufacturers, thus achieving multi-functionality and universality.
2Adaptability or versatility
If protocol detection and adaptation processes are implemented, then device compatibility improves, but system complexity and detection time increase
Solution Approach 1:
The patent performs protocol detection and identification during the charging connection establishment phase, before actual writing interaction begins. The electronic device pre-detects the charging protocol type (USB Type-C, USB Type-A, or wireless charging) and prepares the appropriate communication protocol in advance. This preliminary action ensures that when writing interaction starts, the correct protocol is already in place, avoiding delays and reducing the complexity of real-time protocol switching.
3Measurement precision
If manual protocol selection is required for writing interaction devices, then protocol accuracy improves, but user operation complexity increases
Solution Approach 1:
The patent implements automatic protocol detection and identification functionality within the electronic device. When a writing interaction device is connected for charging, the system automatically detects the charging protocol type, identifies the corresponding communication protocol, and configures the interaction without requiring any manual user input. The user simply needs to connect the device, and the system handles protocol matching autonomously, maintaining high accuracy while ensuring ease of operation.
