Solution Overview

Problem

Existing communication systems between terminal devices and information processing devices may establish connections with unintended devices when multiple devices are present, due to lack of clear user identification, leading to inefficient and potentially incorrect connections.

Innovation Solution

Implementing a dual wireless communication scheme system where a terminal device establishes an initial connection using a second wireless communication scheme, sends a request for user confirmation, and upon receiving a response, switches to a first wireless communication scheme for a stable connection, ensuring user-verified connections are established based on the Wi-Fi Direct scheme.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If a terminal device establishes communication connection with information processing device based on wireless communication scheme without user confirmation, then connection speed is improved, but connection reliability deteriorates due to potential connection with unintended device

Engineering Contradiction:

Improveconnection speedVSAvoidconnection reliability

Core Design Contradiction:

SpeedVSReliability

Solution Approach 1:

The patent performs user confirmation through display section and operation section before establishing the final communication connection. This preliminary action of obtaining user approval ensures that the terminal device connects to the intended information processing device, preventing unintended connections while maintaining efficient communication setup

Inventive Principle:

Principle #10Preliminary action

2Reliability

If user confirmation process is added to verify intended device before connection, then connection reliability is improved, but operation complexity increases

Engineering Contradiction:

Improveconnection reliabilityVSAvoidoperation simplicity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The terminal device automatically displays connection information and waits for user confirmation without requiring manual device selection or complex user input. The operation section simply needs to receive user approval, making the confirmation process intuitive and easy while ensuring reliable connection to the intended device

Inventive Principle:

Principle #25Self-service

AI summary

A printing system includes a smart device and a printer, and the smart device establishes a communication connection with the printer based on a BLE communication scheme, transmits a first request that requests a process relating to connection confirmation by a user, and establishes a communication connection with the printer based on a Wi-Fi Direct communication scheme when the smart device receives, from the printer, a response to the first request, and the printer performs, based on the first request received, connection confirmation display for prompting a user to perform the connection confirmation, transmits, when receiving a user operation based on the connection confirmation display, a response to the smart device, the response indicating reception of the user operation, and establishes the communication connection with the smart device based on the Wi-Fi Direct communication scheme.
