Solution Overview
Problem
Current screen projection methods using Miracast and DLNA protocols are cumbersome and time-consuming for users, requiring multiple steps and manual settings, which hinders convenience and efficiency in establishing connections between terminal devices and display devices.
Innovation Solution
Implementing a one-touch screen projection system using an NFC tag in a remote control that stores identification information of a display device, allowing a terminal device to initiate a screen projection connection with the display device via NFC communication, utilizing protocols like Miracast or DLNA, and prompting users for acceptance of the connection request.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional screen projection methods using Miracast and DLNA protocols are used, then screen projection functionality is achieved, but the operation process is cumbersome and time-consuming requiring multiple steps and manual settings
Solution Approach 1:
The remote control is pre-configured with the display device's identification information (MAC address, device name) before use. When a user touches the remote control, the terminal device reads this pre-stored information and automatically initiates connection, eliminating the need for manual device search and configuration during actual use.
Solution Approach 2:
The NFC tag in the remote control serves as an intermediary carrier that stores display device identification information. This intermediary enables automatic information transfer from the remote control to the terminal device, facilitating one-touch connection without requiring direct communication between the terminal and display device through complex manual settings.
2Productivity
If manual device pairing and configuration steps are performed, then connection reliability is ensured, but operational efficiency and user experience are reduced
Solution Approach 1:
The complex manual pairing process is extracted and replaced by an automated NFC-based identification system. The terminal device extracts identification information from the NFC tag and automatically uses it to establish connections, removing the need for users to manually search, select, and configure devices.
Solution Approach 2:
The system performs self-service by automatically reading device identification information from the NFC tag, validating the display device, and initiating connections without requiring user intervention in the technical configuration process. The system handles all pairing operations autonomously based on the pre-stored information.
