Innovation Solution

A network connection system for home appliances that includes a communication unit, memory for storing an IP address, and a processor to control the communication unit in AP mode, allowing it to connect to a terminal device, verify authentication information, and establish a secure connection with an AP apparatus, enabling easy and secure network access to a server.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a home appliance connects to a network using traditional authentication methods, then network security is maintained, but the connection process becomes complex and error-prone for users

Engineering Contradiction:
Improvenetwork securityVSAvoidconnection setup process
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces a terminal device as an intermediary that mediates between the home appliance and the network. The terminal device generates authentication information and transmits it to the home appliance, which then uses this information to connect to the network. This intermediary approach simplifies the user experience while maintaining security through automated authentication.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The terminal device performs preliminary authentication actions by generating and providing authentication information to the home appliance before the actual network connection is established. This preliminary authentication step simplifies the subsequent connection process while ensuring security requirements are met.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If authentication information is transmitted from terminal device to home appliance, then connection ease is improved, but security risks may increase during transmission

Engineering Contradiction:
Improveconnection setup processVSAvoidsecurity risks during transmission
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The AP apparatus serves as a trusted intermediary that receives authentication information from the terminal device and validates it before allowing network access. This intermediary verification process ensures that authentication information is properly handled while maintaining security, reducing the risks associated with direct transmission.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements a feedback mechanism where the AP apparatus verifies the authentication information received from the terminal device and provides confirmation to the home appliance. This feedback loop ensures that authentication is properly validated, maintaining security while enabling easy connection setup.

Inventive Principle:
Principle #23Feedback

3Ease of operation

If the home appliance operates in AP mode to connect to terminal device, then network access is simplified, but device functionality complexity increases

Engineering Contradiction:
Improvenetwork access processVSAvoidcommunication unit operation modes
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The communication unit dynamically switches between different operation modes (AP mode and station mode) based on the connection phase. It operates in AP mode initially to receive authentication information from the terminal device, then transitions to station mode to connect to the network through the AP apparatus. This dynamic mode switching simplifies the overall access process while managing device complexity through contextual functionality.

Inventive Principle:
Principle #15Dynamics
