Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the data card is used as the laser pen, then the laser indication function is available, but the data card must be disconnected from the PC and cannot perform page turning control
Solution Approach 1:
The device is designed to perform multiple functions including data card operations, laser pen indication, and presentation control simultaneously or alternatively. The control unit can identify different operation types (data transmission, laser control, presentation navigation) and route them appropriately, allowing the single device to serve multiple purposes without requiring separate dedicated devices for each function.
2Adaptability or versatility
If the data card is connected to the PC for data access, then network functionality is available, but the laser pen function cannot be used simultaneously
Solution Approach 1:
The device dynamically switches between different operational modes (data card mode, laser pen mode, presentation control mode) based on user needs and contextual information. The control unit can rapidly identify the current operation type and adjust the device state accordingly, enabling seamless transitions between functions without requiring physical disconnection or lengthy reconfiguration processes.
3Device complexity
If simple indication function is implemented, then the device structure is simple, but intelligent control during laser operation cannot be achieved
Solution Approach 1:
The control unit continuously monitors operation information and provides feedback to determine the current operation type. By analyzing the received information and comparing it against known patterns for different functions (data transmission, laser indication, presentation control), the system automatically adjusts its behavior and enables intelligent control features such as context-aware laser activation and automated presentation navigation based on the detected operation state.

AI summary
The disclosure discloses a method and device for sending and receiving data, which are used to solve the problem that the existing device having the function of the laser pen and the function of the data card cannot implement the integrated control over the function of the laser pen and the function of the data card. The device includes a main module and a connection module. The connection module is configured to connect to a PC by using a USB mode, and the main module communicates with the connection module by high frequency. The method for sending data includes: the main module encapsulates data to be sent according to a type of the data to be sent and identification information corresponding to the type of the data, and sends the encapsulated data to the connection module; and the connection module decapsulates the encapsulated data and sends the decapsulated data to the PC. Since the device determines the identification information corresponding to the type according to the type of the received data, and encapsulates the identification information and the data, in order to be capable of performing corresponding processing when needed, so that intelligent integration of the function of the laser pen and the function of the data card is implemented and an intelligent control over the function of the laser pen is implemented.
