Barcode P2P Connection Setup for Networked Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of lengthy identification codes in point-to-point (P2P) network connections makes it cumbersome for users, especially with devices like smartphones, to establish connections between terminal and networked devices.
Innovation Solution
A system that uses barcodes corresponding to identification codes, where networked devices register with a server and terminal devices capture these barcodes to generate connection request signals, allowing the server to establish P2P connections without manual input of lengthy codes, incorporating security measures like default passwords.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If identification codes are used to identify networked devices, then device identification and connection management are enabled, but user input complexity and connection establishment time increase significantly
Solution Approach 1:
The patent applies the copying principle by creating a barcode (visual copy) that represents the identification code. Instead of requiring users to input the actual identification code, the system generates a barcode that contains the same information and can be scanned by the terminal device. This visual copy simplifies the connection process while maintaining the unique identification capability.
Solution Approach 2:
The patent replaces the mechanical input method (manual typing of identification codes) with an optical scanning method. The terminal device uses its camera or barcode scanner to capture the barcode image, automatically extracts the identification code, and initiates the connection process. This substitution eliminates the need for manual input of lengthy codes.
2Productivity
If manual input of identification codes is required, then connection establishment is possible, but connection establishment time increases
Solution Approach 1:
The patent applies preliminary action by pre-generating and displaying the barcode on the networked device before the connection process begins. The barcode is ready to be scanned at any time, eliminating the need for manual code entry during the connection establishment phase. This preparation in advance significantly reduces the time required for connection.
Solution Approach 2:
The patent replaces the time-consuming manual input process with rapid optical scanning. The terminal device's camera captures the barcode image in fractions of a second, and the system automatically processes the information to establish the connection. This substitution reduces connection establishment time from potentially minutes to seconds.
3Measurement precision
If lengthy identification codes are used, then device identification precision is maintained, but user input difficulty increases
Solution Approach 1:
The patent creates a barcode that serves as a visual representation of the identification code. The barcode maintains the full precision of the original identification code while transforming it into a format that is easy to capture and process. The scanning system reads the entire barcode content accurately, preserving the unique identification capability regardless of the original code's length or complexity.
Data Source
AI summary
A barcode corresponding to an identification of the networked device is attached on a networked device, and the identification is associated with an IP address of the networked device in a server, wherein a terminal device captures the barcode for transmitting a connection request to the server; and the server obtains the identification code of the networked device according to the connection request, wherein the IP address of the networked device is obtained according to identification code for establishing a point to point (P2P) connection between the terminal device and the networked device.
