Solution Overview

Problem

Existing methods for setting communication parameters in wireless networks are cumbersome and insecure, as they often result in fixed parameters that can be compromised if obtained by third parties, and users must manually select between multiple automatic setting methods, increasing operational complexity.

Innovation Solution

A communication parameter setting method that automatically detects network identifiers and authenticates communication apparatuses, allowing the selection of a corresponding setting method to dynamically set communication parameters, ensuring security and convenience by varying parameters with each use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If fixed communication parameters are set for wireless networks, then configuration is simplified, but security is compromised when parameters are obtained by third parties

Engineering Contradiction:

Improveconfiguration simplicityVSAvoidsecurity

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent applies dynamics by transitioning from fixed communication parameters to dynamically generated parameters. The communication parameters are automatically generated during each connection establishment, ensuring that parameters change over time rather than remaining static. This resolves the contradiction by maintaining ease of operation through automatic generation while improving security through temporal variability.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent implements parameter changes by varying communication parameters for each connection session. Instead of using predetermined fixed values, the system generates different parameter sets (such as encryption keys, SSIDs, or authentication credentials) dynamically. This ensures that even if parameters are intercepted, they become obsolete after one use, thereby maintaining both operational simplicity and security.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If multiple automatic communication parameter setting methods are supported, then adaptability is improved, but user operation complexity increases due to manual selection requirements

Engineering Contradiction:

Improvemethod selection flexibilityVSAvoiduser operation steps

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent applies self-service by enabling the communication apparatus to automatically select and execute the appropriate parameter setting method without user intervention. The system autonomously determines which automatic setting method to use based on the connection context, eliminating the need for users to manually choose among multiple methods. This maintains adaptability while significantly reducing operational complexity.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Instead of requiring users to select from multiple available methods, the patent inverts the control flow by having the system automatically determine and select the appropriate method. The apparatus autonomously evaluates available automatic setting methods and executes the most suitable one, thereby preserving versatility while simplifying user interaction to minimal or no steps.

Inventive Principle:

Principle #13The other way round (Inversion)

3Reliability

If automatic parameter generation is implemented for each communication, then security is enhanced, but device complexity increases due to multiple setting methods

Engineering Contradiction:

ImprovesecurityVSAvoidnumber of setting methods

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies universality by designing a unified automatic parameter setting framework that can handle multiple setting methods through a single integrated mechanism. Rather than implementing separate complex systems for each method, the apparatus uses a universal automatic selection and execution framework that supports various parameter generation approaches (such as WPS, WPA, or custom protocols) within one cohesive structure. This reduces device complexity while maintaining security through dynamic parameter generation.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

To set communication parameters, a communication apparatus identifies a communication parameter setting wireless network on the basis of a network identifier provided in itself. If the communication apparatus can identify any network identifier matching the network identifier provided in itself, it sets the communication parameters in cooperation with another communication apparatus in the wireless network. If no identifier can be identified, the communication apparatus switches the setting of the communication parameters to a manual operation.
