Control method using application in portable terminal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication devices without displays or that are difficult to use for specifying access points for wireless connections require manual user input to establish connections, which can be cumbersome.
Innovation Solution
A control method using a portable terminal application that instructs the OS to connect to a communication device in software access point mode, sending the SSID and password to establish a wireless connection without user input for access point specification, specifically designed for devices like refrigerators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a communication device without a display or with limited display capability is used, then device complexity is reduced, but ease of operation deteriorates because users cannot easily specify access points
Solution Approach 1:
The patent introduces a portable terminal (smartphone or tablet) as an intermediary device that displays access point information and receives user input. This mediator handles the complex interaction between the user and the communication device, allowing the communication device itself to remain simple without a display while still enabling users to specify access points through the portable terminal's interface
Solution Approach 2:
The patent divides the system into two functional parts: the portable terminal that handles user interaction and display functions, and the communication device that focuses on wireless communication. By segmenting the responsibilities, the communication device can be simplified while the portable terminal provides the necessary user interface capabilities
2Reliability
If manual user input is required to specify access points, then connection reliability is improved, but loss of time increases due to cumbersome input processes
Solution Approach 1:
The patent implements preliminary action by having the portable terminal automatically obtain and store access point information (SSID, password) before the user needs to connect. The terminal retrieves this information from the application in advance, so when connection is needed, the user simply selects from pre-fetched options rather than manually entering details, thus reducing time loss while maintaining reliable connections

AI summary
A control method that is achieved by a refrigerator application installed in portable terminal, the control method including the steps of instructing an operating system (OS) of portable terminal to connect to a refrigerator in operation in a software access point mode, and sending a service set identifier (SSID) of an access point and a password for connecting to the access point to the refrigerator. An SSID of the refrigerator that operates in the software access point mode, and a password for connecting to the refrigerator that operates in the software access point mode are incorporated in the refrigerator application in advance.
