Solution Overview

Problem

Existing wireless communication systems face inefficiencies due to unnecessary connections being established, which can degrade network operation efficiency and require excessive processing for parameter setting and role decision.

Innovation Solution

A communication apparatus provides setting information including connection parameters and identification information to enable efficient connection to a network, using QR codes or NFC for direct communication, and service detection methods to determine optimal network connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If connection parameters are provided for multiple connection forms, then connection versatility is improved, but unnecessary connections may be established degrading network operation efficiency

Engineering Contradiction:

Improveconnection versatilityVSAvoidnetwork operation efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent applies preliminary action by providing connection parameters in advance for multiple connection forms (direct connection and access point connection) before the actual connection decision is made. The communication apparatus prepares and provides both direct connection parameters and access point connection parameters beforehand, allowing the partner apparatus to make an informed connection decision without needing to establish unnecessary connections. This resolves the contradiction by enabling versatile connection options while preventing inefficient unnecessary connections through advance information provision.

Inventive Principle:

Principle #10Preliminary action

2Speed

If service detection is performed after connection establishment, then connection speed is improved, but processing time for parameter setting increases

Engineering Contradiction:

Improveconnection speedVSAvoidprocessing time for parameter setting

Core Design Contradiction:

SpeedVSLoss of time

Solution Approach 1:

The patent applies preliminary action by having the communication apparatus provide connection parameters in advance before the actual connection is established. The partner apparatus receives and processes connection parameters beforehand, so when connection time arrives, the processing is already prepared, reducing the processing time required during connection establishment while maintaining fast connection speed.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent uses QR codes as an intermediary to transfer connection parameters efficiently. The communication apparatus encodes connection parameters into a QR code that the partner apparatus can quickly capture and decode, eliminating the need for lengthy manual parameter input and reducing processing time while maintaining connection speed.

Inventive Principle:

Principle #24Intermediary (Mediator)
