Controlling Apparatus for Wireless Network Frequency Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices, such as printers, that are not set to a wireless network cannot connect to a wireless communication network even when provided with a network wireless setting, as they may not be capable of using the frequency used by the existing network, leading to inability to execute wireless communication.
Innovation Solution
A controlling apparatus that searches for nearby access points and selects a suitable wireless identifier from those that use a different frequency, allowing the device to set itself to the new network, enabling wireless communication by generating a new wireless profile with the selected identifier.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a first printer sends a network wireless setting to a second printer using ad-hoc wireless connection, then the second printer receives the wireless setting, but the second printer cannot connect to the wireless communication network because it is not capable of using the frequency used by the original network
Solution Approach 1:
The system changes the frequency parameter of the wireless network by searching for access points operating on different frequencies (e.g., 2.4 GHz vs 5 GHz). The controlling apparatus modifies the network parameters to match the capabilities of the unset device, selecting an access point whose frequency the target device can actually use.
Solution Approach 2:
The controlling apparatus acts as an intermediary between the set device and the unset device. It searches for suitable access points, selects appropriate wireless identifiers, and transmits the modified wireless settings to the unset device, enabling successful connection without requiring the unset device to directly connect to the original network.
2Ease of operation
If the second printer uses the received wireless setting to connect to the network, then it attempts to establish wireless communication, but the connection fails because the frequency is incompatible
Solution Approach 1:
The unset device performs self-service by automatically searching for suitable access points and selecting appropriate wireless identifiers based on its own frequency capabilities. The device independently determines which networks it can join without requiring manual configuration or user intervention about frequency compatibility.
Solution Approach 2:
The system automatically changes the wireless network parameters (frequency, SSID) to match the unset device's capabilities. The controlling apparatus or unset device modifies the network parameters from the original settings to compatible settings, ensuring the device can actually connect to the selected network.
3Reliability
If the controlling apparatus searches for multiple access points and selects a suitable wireless identifier, then the unset device can connect to a compatible network, but the setup process becomes more complex
Solution Approach 1:
The controlling apparatus serves as an intermediary that automates the complex process of searching for access points, comparing frequency compatibility, selecting suitable wireless identifiers, and transmitting modified settings. This centralizes the complexity in a single device rather than requiring the unset device to perform complex searches and selections.
Solution Approach 2:
The controlling apparatus performs preliminary actions by pre-searching for available access points and pre-selecting compatible wireless identifiers before the unset device attempts connection. This advance preparation ensures that only compatible networks are presented to the unset device, simplifying its task and ensuring connection success.

AI summary
The controlling apparatus may search for one or more access points so as to obtain N items of wireless identifiers, in a case where a first wireless network to which a set device belongs is a first type of wireless network in which a carrier wave having a first frequency is used. A first wireless identifier has been set in the set device and an unset device is a first type of device which is not capable of using the carrier wave having the first frequency. The controlling apparatus may obtain, from a memory of the set device, the first wireless identifier for identifying the first wireless network, select, based on the first wireless identifier, a second wireless identifier from among one or more wireless identifiers included in the N items of wireless identifiers, and execute a first setting process for setting the second wireless identifier in the unset device.
