Communal Device QR Access for Temporary Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless networks require guests to obtain network IDs and passcodes manually, which is inconvenient and insecure for providing temporary network access.
Innovation Solution
A communal device generates a machine-readable code encoding network connection information, allowing user devices to connect automatically without further input, while maintaining security through separate network connections and temporary storage of information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional wireless networks require manual passcode entry for guest access, then network security is maintained, but user convenience and ease of operation deteriorates
Solution Approach 1:
The patent replaces the mechanical manual passcode entry system with an optical/electronic machine-readable code system. Users scan the code displayed on the communal device using their mobile device cameras, eliminating the need for manual typing of passcodes while maintaining network security through encoded authentication credentials.
Solution Approach 2:
The patent creates a machine-readable copy (visual code) of the network authentication credentials that can be scanned and processed automatically. This copy contains the same authentication information as the original passcode but in a machine-readable format that enables automatic connection without manual intervention.
2Ease of operation
If network credentials are stored permanently for guest access, then ease of operation improves, but security and control deteriorates
Solution Approach 1:
The patent uses temporary, single-use machine-readable codes that are displayed only for the duration needed to grant access. These codes are not stored permanently but are generated on-demand and can be discarded after use, providing convenient access while minimizing security risks from credential storage.
Solution Approach 2:
The patent generates and displays the machine-readable code in advance of the actual connection need, allowing users to scan and save credentials before they need to connect. This preliminary provision of access information eliminates the need for real-time credential distribution while maintaining security through controlled code generation.
3Ease of operation
If a communal device displays machine-readable codes for network access, then user convenience improves, but device complexity increases
Solution Approach 1:
The patent implements a communal device that serves multiple functions: it displays machine-readable codes for network access, provides information about available networks, and potentially offers other communal services. This multi-functionality justifies the added complexity by providing comprehensive guest support through a single device.
Solution Approach 2:
The communal device automatically retrieves network information and generates appropriate machine-readable codes without requiring manual configuration. The device serves itself by autonomously managing the code generation and display process, reducing the operational complexity despite increased functional capabilities.

AI summary
Methods, systems, and devices are provided that allow for access to a wireless computer network, such as a home or business network, via a communal device. The communal device retrieves network access information such as a PSK and provides a machine-readable code such as a QR code or bar code that automatically provides the access information to a user's device, thereby allowing access to the network with little or no user input required.
