Wireless Device Selection via Access Point Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in determining whether a printer is connected to the correct access point when using a mobile information terminal, leading to repeated selection attempts until the correct access point is found.
Innovation Solution
A non-transitory computer-readable medium with an information processing program that stores device specification information and relay device identification information, allowing the program to associate and display this information, enabling users to connect to the correct relay device without considering the intermediate relay device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the information terminal displays only SSID of access points for user selection, then the display interface remains simple, but the user cannot determine whether the desired printer is connected to the selected access point
Solution Approach 1:
The information is segmented into two levels: the display interface shows only SSID (access point level), while the internal storage and selection logic handle detailed device-to-access-point mapping (printer level). This segmentation allows the interface to remain simple while the system maintains complete connection information.
Solution Approach 2:
The system introduces an intermediary mapping mechanism that associates printer specification information with access point SSIDs. When a user selects a printer, the system automatically identifies and connects to the corresponding access point through this intermediary mapping, hiding the complexity from the user.
2Reliability
If the user manually selects access points one by one to find the correct printer, then connection reliability is eventually achieved, but the time and operational burden increase significantly
Solution Approach 1:
The system performs preliminary actions by pre-establishing and storing the mapping between printers and access points before the user needs to connect. When connection is needed, the system has already prepared the association information, eliminating the need for users to manually test multiple access points.
Solution Approach 2:
The system provides feedback to the user by displaying which access point will be used when a printer is selected. This feedback mechanism allows users to verify the connection path before actual connection, ensuring reliability while saving time by avoiding trial-and-error selection.
3Ease of operation
If the system stores and displays detailed device and relay device information, then users can easily select the correct printer, but the data structure and processing complexity increase
Solution Approach 1:
The system merges printer specification information with access point identification information into a unified data structure. By combining these previously separate data elements, the system simplifies the overall structure while providing comprehensive information for easy user selection.

AI summary
A non-transitory computer-readable medium having an information processing program readable by a computer in an information processing apparatus including a connection unit connected to a relay device that a target device is wirelessly connected to, the information processing program causes the computer to perform operations including: storing device specification information for specifying the target device and relay device identification information for identifying the relay device in a storage unit so as to be associated with each other; displaying a plurality of the device specification information stored in the storage unit; accepting the device specification information from the plurality of the displayed device specification information through an input unit; and connecting the connection unit to the relay device identified by the relay device identification information stored in the storage unit so as to be associated with the designated device specification information.
