Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing communication systems between terminal devices and communication devices, such as cameras and printers, require users to perform cumbersome operations like inputting connection information, making the process inconvenient.

Innovation Solution

A control method where a terminal device stores predetermined connection information and uses it to connect with a communication device without requiring user input, allowing for automatic establishment and data transmission, using pre-stored fixed connection information for simple connection modes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the terminal device requires user input of connection information to establish communication, then connection security is improved, but user operability deteriorates

Engineering Contradiction:

Improveconnection securityVSAvoiduser operability

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The terminal device stores connection information (SSID and password) in advance before actual communication is needed. When communication is initiated, the pre-stored information is automatically used without requiring user input, thus maintaining security while improving ease of operation.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The terminal device automatically selects and uses the pre-stored connection information without requiring user intervention. The system serves itself by automatically establishing connections using stored credentials, eliminating the need for manual password input while maintaining secure connections.

Inventive Principle:

Principle #25Self-service

2Measurement precision

If the terminal device requires user input of connection information to establish communication, then connection accuracy is improved, but time consumption increases

Engineering Contradiction:

Improveconnection accuracyVSAvoidtime consumption

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

Connection information is stored in advance in the terminal device. When communication is needed, the pre-stored accurate information is immediately used, eliminating the time required for manual input while ensuring connection accuracy is maintained.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If the terminal device uses pre-stored connection information for automatic connection, then ease of operation is improved, but connection flexibility deteriorates

Engineering Contradiction:

Improveuser operabilityVSAvoidconnection flexibility

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The terminal device dynamically selects from multiple pre-stored connection information sets based on the current communication needs. The system can switch between different stored SSID/password combinations, maintaining ease of automatic operation while preserving flexibility to connect to different devices as needed.

Inventive Principle:

Principle #15Dynamics

AI summary

A terminal device stores, without accepting user input of predetermined connection information, predetermined connection information without acquiring the predetermined connection information from a communication device, connects to the communication device using the stored predetermined connection information, and communicates with the communication device using the predetermined connection information.
