Solution Overview

Problem

Existing wireless communication apparatuses with multiple station functions face challenges in increasing the number of networks they can connect to, due to difficulties in preventing the selection of already connected access points, which degrades operability.

Innovation Solution

A wireless communication apparatus with multiple station functions includes a detection unit for detecting access points, a selection unit for choosing an access point to connect, and a control unit that ensures an access point already connected via one station function is not selected for connection via another station function.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple STA functions are configured to operate in parallel to connect with multiple APs, then the number of networks to be connected increases, but the risk of selecting the same already-connected AP increases, degrading operability

Engineering Contradiction:
Improvenumber of networks to be connectedVSAvoidoperability
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system applies preliminary anti-action by proactively preventing the selection of already-connected APs before the user can make an incorrect choice. The control unit identifies APs that are already connected through other STA functions and excludes them from the selectable list, thereby preventing the harmful action of duplicate connections before they can occur.

Inventive Principle:
Principle #9Preliminary anti-action

Solution Approach 2:

The system implements feedback by continuously monitoring the connection status of all STA functions and using this information to dynamically adjust the list of selectable APs. The control unit receives feedback about which APs are already connected and uses this feedback to prevent their re-selection, creating a closed-loop system that adapts to the current connection state.

Inventive Principle:
Principle #23Feedback

2Reliability

If users carefully perform operations to prevent selecting the same AP, then duplicate connections are prevented, but operability is degraded due to increased operational complexity

Engineering Contradiction:
Improveprevention of duplicate connectionsVSAvoidoperability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system applies self-service by automatically managing the prevention of duplicate connections without requiring user intervention. The control unit autonomously identifies already-connected APs and excludes them from the selectable list, freeing the user from the burden of manually tracking connection status and making the system self-regulating.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system proactively prevents the need for careful user operations by automatically excluding already-connected APs from the selection list before the user can make a choice. This preliminary anti-action eliminates the need for users to exert extra care or attention to prevent duplicate connections.

Inventive Principle:
Principle #9Preliminary anti-action

AI summary

There is provided a wireless communication apparatus having a plurality of station functions and being connectable with a plurality of access points in parallel. The apparatus detects access points, and selects an access point to be connected with the wireless communication apparatus, from the detected plurality of access points. The apparatus performs control so that an access point having already been connected via a first station function is not selected as an access point to be connected via a second station function.
