Solution Overview

Problem

Existing wireless communication devices face issues with manual setting of communication parameters, such as SSID, frequency channels, and encryption keys, which can lead to unusable or malfunctional settings due to specification differences between devices, and may violate regional laws if inappropriate parameters are used.

Innovation Solution

A communication device with a receiving unit, determining unit, and control unit that checks the number of characters, presence of specific characters, and regional legality of communication parameters received during automatic setting, preventing the use of unusable or prohibited parameters by controlling the setting process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If communication parameters are automatically provided from a providing device to a receiving device using WPS, then the ease of operation is improved, but the reliability deteriorates due to specification differences causing unusable parameters or malfunctions

Engineering Contradiction:
Improveautomatic parameter settingVSAvoidparameter usability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent applies preliminary action by checking communication parameter validity before actual use. The determining unit validates parameters (checking character counts, prohibited characters, frequency channel legality) before the receiving device commits to using them, preventing unusable parameters from causing malfunctions later

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback by having the determining unit continuously monitor and validate communication parameters during the automatic setting process. When invalid parameters are detected, the system provides feedback to prevent their use, ensuring only valid parameters are applied

Inventive Principle:
Principle #23Feedback

2Productivity

If communication parameters are automatically provided without validation, then the productivity is improved, but the harmful factors increase due to legal violations from prohibited frequency channels

Engineering Contradiction:
Improveparameter setting speedVSAvoidlegal violation risk
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent applies preliminary action by checking frequency channel legality before use. The determining unit verifies that frequency channels in received parameters are permitted in the current region, preventing legal violations before they occur

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent applies preliminary anti-action by proactively identifying and blocking prohibited frequency channels before they can be used. The system preemptively prevents the harmful effect of legal violations by rejecting parameters with prohibited channels in advance

Inventive Principle:
Principle #9Preliminary anti-action

3Ease of operation

If communication parameters are automatically provided without checking, then the ease of operation is improved, but the device complexity increases due to potential malfunctions and garble in display units

Engineering Contradiction:
Improvemanual setting eliminationVSAvoidparameter validation complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent applies self-service by enabling the receiving device to automatically validate its own received parameters. The determining unit performs self-checks on character counts, prohibited characters, and frequency channel legality without external intervention, reducing the need for complex external validation systems

Inventive Principle:
Principle #25Self-service

AI summary

When a communication parameter provided from a communication device is received in a communication parameter automatic setting process, it is determined whether the number of characters in the communication parameter is a predetermined number, whether the communication parameter includes a predetermined character, or whether the communication parameter is a communication parameter use of which is prohibited in a certain region. In accordance with a determination result, control is performed so that the communication parameter is not used.
