Solution Overview

Problem

In environments with multiple dual-terminal wireless communication apparatuses, bandwidth is wasted when one dual terminal constructs a new network in AP mode, disrupting existing data communication with wired terminals.

Innovation Solution

A communication apparatus with determination and construction means to assess if it is communicating with another network and switch to AP mode to construct a new network without interrupting existing communications, ensuring continued communication with wired terminals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a dual terminal constructs a new network in AP mode to ensure communication bandwidth, then communication bandwidth between wireless terminals is improved, but communication with wired terminals is disrupted and bandwidth is wasted

Engineering Contradiction:
Improvecommunication bandwidthVSAvoidcommunication continuity
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The dual terminal dynamically switches between STA mode and AP mode based on real-time network conditions and communication requirements. When bandwidth insufficiency is detected, the terminal transitions to AP mode to construct a new network, thereby adaptively optimizing communication performance while maintaining flexibility in mode selection

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The determination unit acts as an intermediary that assesses network conditions before mode switching. It determines whether the terminal is communicating with wired terminals through the base station, and only permits AP mode construction when no such communications exist, thereby preventing disruption to wired terminal connectivity

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If a dual terminal automatically switches to AP mode to construct a new network, then communication bandwidth is assured, but existing data communication with wired terminals is interrupted

Engineering Contradiction:
Improvecommunication bandwidthVSAvoidbandwidth waste
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The determination unit continuously monitors communication status and provides feedback to the mode switching decision. By detecting whether wired terminal communications are in progress, the system receives real-time feedback that prevents premature or inappropriate AP mode construction, thereby avoiding bandwidth waste and communication disruptions

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If multiple dual terminals exist in the network, then network coverage and connectivity are improved, but bandwidth is wasted when one constructs a new network

Engineering Contradiction:
Improvenetwork coverageVSAvoidbandwidth waste
Core Design Contradiction:
Adaptability or versatilityVSLoss of energy

Solution Approach 1:

Each dual terminal applies local decision-making based on its specific communication context. The determination unit evaluates local network conditions and communication patterns to decide whether AP mode construction is appropriate, ensuring that mode switching occurs only when locally beneficial and not when it would cause global bandwidth waste

Inventive Principle:
Principle #3Local quality

AI summary

When a connection is made to a wireless network constructed by a base station, a request to construct a wireless network in which a wireless communication apparatus operates as a base station is sensed and a determination is made as to whether communication is in progress with a communication apparatus of a network different from the wireless network constructed by the base station. If the request to construct the wireless network is sensed and it is determined that communication is in progress with a communication apparatus of a network different from the wireless network in which the base station is the intermediary, then an attempt is made to construct a wireless network in which the wireless communication apparatus operates as a base station.
