Portable Device Code Capture for Wireless LAN Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless setting methods for printers via P2P connections can fail due to long distances or poor communication environments, making it difficult for users to establish connections to wireless networks.
Innovation Solution
A control method that uses a more portable information processing apparatus to capture a two-dimensional code image displayed by a first information processing apparatus, which includes information for connecting to a wireless network, allowing for automatic wireless LAN setup between communication devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If P2P connection is used for wireless setting, then wireless setting can be performed between communication devices, but connection may fail when distance is long or communication environment is poor
Solution Approach 1:
The patent introduces a portable information processing apparatus as an intermediary to capture the code image and transmit connection information. This mediator bridges the gap between the display device and the target communication device, enabling reliable connection establishment even when direct P2P connection fails due to distance or poor communication environment.
Solution Approach 2:
The patent uses a code image (visual copy) to represent connection information instead of direct wireless communication. The portable device captures this visual copy through its imaging function, converting the connection information into a transferable format that is不受 limited by communication environment.
2Reliability
If manual input of connection information is required, then connection can be established, but operation becomes difficult for users
Solution Approach 1:
The patent replaces manual input operations with automated image capture and processing. The portable device's imaging function automatically captures the code image, and the system automatically extracts and transmits connection information, eliminating the need for users to manually input complex connection details.
Solution Approach 2:
The system enables self-service connection establishment where the portable device automatically performs the tasks of capturing connection information, processing it, and transmitting it to the target device. This self-service mechanism eliminates the need for user intervention in complex manual input processes.
3Loss of information
If code image is displayed on non-portable device, then connection information can be shown, but user portability and mobility are reduced
Solution Approach 1:
The patent separates the display function from the portable device by using a non-portable device for displaying the code image while using the portable device's imaging dimension to capture and transmit the information. This dimensional separation allows the system to leverage the display capabilities of larger devices while maintaining the portability advantages of smaller devices.
