Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart devices, such as smart cameras, often lack user interfaces, making it difficult to establish communication with terminals like mobile phones, as they cannot easily obtain and input Wi-Fi connection information for network setup.
Innovation Solution
Methods involving multicast packets for extracting Wi-Fi connection information, generating and decoding QR codes, and forming peer-to-peer connections to facilitate communication between smart devices and terminals, even without user interfaces, by using cloud servers for verification and binding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If smart devices use automated methods to obtain Wi-Fi connection information through multicast packets, then the ease of operation is improved, but the device complexity increases due to automated binding processes
Solution Approach 1:
The smart device automatically obtains Wi-Fi connection information by receiving and processing multicast packets without user intervention. The device autonomously extracts SSID and password from the packets, performs automated binding with the terminal through QR code scanning, and connects to the network independently, eliminating the need for manual user operations.
Solution Approach 2:
Multicast packets serve as an intermediary carrier to transmit Wi-Fi connection information from the terminal to the smart device. The QR code acts as an intermediary for the binding process, encoding terminal identification information that the smart device scans to establish the binding relationship without direct user input.
2Device complexity
If smart devices have no user interface or limited interaction capabilities, then the device complexity is reduced, but the ease of operation deteriorates as users cannot manually input connection information
Solution Approach 1:
The patent replaces the mechanical user interface input system with an automated information reception system. Instead of requiring physical keyboard input or touchscreen interaction, the smart device uses its communication module to receive multicast packets containing connection information, substituting automated electronic processes for manual mechanical operations.
Solution Approach 2:
The multicast packet and QR code serve as intermediaries that bridge the gap between the terminal and the smart device with limited interaction capabilities. These intermediaries carry the necessary binding information, allowing devices without full user interfaces to establish connections through automated scanning and processing rather than manual input.
