Solution Overview

Problem

Users face difficulties in establishing wireless connections with devices operating in direct wireless communication mode when the maximum number of terminals is reached, as they need to manually switch the device between modes, which can be cumbersome and confusing.

Innovation Solution

A communication apparatus with an inquiry unit to check if the maximum number of terminals is connected via Bluetooth Low Energy, and instruction units to stop and restart the device's direct wireless communication mode as needed to accommodate new connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a device operates in direct wireless communication mode with a maximum number of terminals, then wireless connection capacity is limited, but when the maximum number is reached, users face difficulty establishing new connections requiring manual mode switching

Engineering Contradiction:
Improvenumber of connected terminalsVSAvoidease of establishing wireless connection
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The communication apparatus automatically detects when the maximum number of terminals is reached and autonomously switches between direct wireless communication mode and infrastructure mode without requiring manual user intervention. The system monitors connection status, determines appropriate mode transitions, and executes the switching process automatically, allowing users to simply initiate connection requests without needing to understand or manage mode changes.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The device dynamically switches between two operational modes (direct wireless communication mode and infrastructure mode) based on real-time connection status. When the maximum number of terminals is reached in direct mode, the system automatically transitions to infrastructure mode to accommodate additional connections, and can switch back when conditions change, creating a flexible adaptive system that responds to changing connection demands.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the device automatically switches modes to accommodate new connections, then ease of operation improves, but device complexity increases

Engineering Contradiction:
Improveease of establishing wireless connectionVSAvoidcomplexity of mode management
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The communication apparatus implements a feedback mechanism where the communication determination unit continuously monitors the number of connected terminals and the operational mode status. Based on this feedback information, the mode switching unit automatically determines when mode transitions are necessary and executes appropriate switches. This closed-loop control system manages the complexity internally while presenting a simple interface to users, who only need to initiate connection requests without managing mode complexity.

Inventive Principle:
Principle #23Feedback

AI summary

In a case where wireless connection to a device fails because the number of terminals in wireless connection with the device has reached a maximum number, a communication apparatus instructs the device to stop operating in a direct wireless communication mode.
