Solution Overview

Problem

Existing methods for connecting a communication apparatus to an access point are cumbersome, requiring simultaneous button pressing or wired connections, which complicates the setup process and affects communication security and usability.

Innovation Solution

A cableless setup method is introduced, allowing a mobile terminal device to connect a multifunction peripheral (MFP) to an access point using Wi-Fi Direct (WFD) with enhanced features like OFDMA and TWT, enabling secure and user-friendly wireless configuration without physical cables.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If simultaneous button pressing is employed for Wi-Fi Protected Setup, then wireless communication setting can be configured, but the communication apparatus and the AP need to be placed at positions where both can be operated at the same time, increasing operational complexity

Engineering Contradiction:
Improveease of wireless configurationVSAvoidoperational complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

A terminal device is introduced as an intermediary to perform the connection process. The terminal device transmits the connection process to the communication apparatus, eliminating the need for simultaneous button pressing and allowing the communication apparatus to be placed in positions where it cannot be operated simultaneously. This mediator approach resolves the contradiction by shifting the operational burden to the terminal device.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If registration is performed via a wired interface, then connection can be established, but it is necessary to prepare a wired cable and connect the communication apparatus and the AP using the wired cable, making the operation complicated

Engineering Contradiction:
Improveconnection reliabilityVSAvoidease of setup
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The mechanical wired connection system is replaced with a wireless communication system. The terminal device performs the connection process wirelessly by transmitting connection information to the communication apparatus, eliminating the need for physical cable preparation and connection. This substitution maintains connection reliability while significantly improving ease of operation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If a terminal performs the process of connecting the communication apparatus to an AP, then wireless configuration is simplified, but both communication security and usability are required to be maintained

Engineering Contradiction:
Improveease of wireless configurationVSAvoidcommunication security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The terminal device receives connection information from the access point and transmits it to the communication apparatus through a controlled feedback process. This structured information transmission ensures that connection credentials are securely delivered while maintaining usability. The feedback mechanism allows the terminal to verify and manage the connection process, balancing security requirements with ease of operation.

Inventive Principle:
Principle #23Feedback
