Wireless Apparatus Resolves SSID Collision via Temporary Disconnection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, establishing a connection to a specific device is challenging when multiple devices share the same network identification information, leading to difficulties in determining the intended device for connection.
Innovation Solution
A wireless communication apparatus that searches for network identification information, determines the unique device by tracking the disappearance and reappearance of specific IDs, and guides the user to turn the device's wireless function off and on to establish a connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If common network identification information is set for wireless communication devices of the same model to improve productivity, then manufacturing efficiency is improved, but it becomes difficult to determine the specific device for connection when multiple devices with the same network ID are found
Solution Approach 1:
The system performs preliminary actions by having the wireless communication device turn off its wireless function temporarily before the connection is established. This preliminary state change allows the wireless communication apparatus to distinguish the target device from others with identical network IDs, as the target device's network ID will disappear from the search results during this period.
Solution Approach 2:
The system uses feedback mechanisms by monitoring the search results for network identification information. When the wireless communication device turns off its wireless function, the network ID disappears from the search results, providing feedback that confirms the identity of the target device. This feedback loop continues until the device turns back on, confirming the correct device has been identified.
2Measurement precision
If individual network identification information is set for each wireless communication device to enable unique identification, then connection accuracy is improved, but productivity of wireless communication devices decreases
Solution Approach 1:
The system applies local quality by making the network identification information temporarily unique to the target device through the off-on cycle. While most devices share common network IDs for mass production compatibility, the target device temporarily distinguishes itself by turning off its wireless function, creating a local distinction that enables precise identification without changing the global configuration.
3Adaptability or versatility
If the wireless communication apparatus searches for network identification information among multiple devices, then the ability to find the target device is improved, but the time required to establish connection increases due to difficulty in determining the specific device
Solution Approach 1:
The system uses periodic action by having the wireless communication device periodically turn off and on its wireless function. This periodic state change creates a temporal pattern that allows the wireless communication apparatus to identify the target device through the disappearance and reappearance of its network ID in search results, significantly reducing the time needed to establish connection compared to manual identification methods.

AI summary
A wireless communication apparatus comprises: a search unit; a determination unit; and a wireless connection processing unit. The search section carries out an SSID (network identification information) search for at least one wireless communication device that has an access point function via a wireless communication section. The determination unit determines, among SSIDs found as a result of search, an SSID that disappeared from the search target of the wireless communication section and has appeared again after disappearance. The wireless connection processing section recognizes, as a connection target device, the wireless communication device corresponding to the determined network identification information, and performs processing for wireless connection to the connection target device. The user operates an operation unit in accordance with the instruction of the guidance screen of the wireless communication apparatus to turn a soft access point OFF and thereafter ON.
