Solution Overview

Problem

Conventional home appliance registration methods require customers to input physical keys within a limited time, which is cumbersome and often results in registration failures due to varying input methods and guide contents for each product.

Innovation Solution

A mobile terminal automatically registers home appliances to a server by receiving an auto-registration key, performing the registration in the background, and eliminating the need for physical key input.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If automatic registration is implemented, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improveregistration operationVSAvoidsystem structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system performs automatic product registration without requiring user intervention. The mobile terminal automatically searches for the home appliance, retrieves the auto-registration key, and completes the registration process in the background, allowing the system to serve itself rather than requiring manual user operation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The mobile terminal acts as an intermediary between the home appliance and the server. It facilitates the automatic registration process by communicating with both the home appliance (to obtain MAC address) and the server (to retrieve auto-registration key and complete registration), thereby simplifying the user interface while adding functional complexity to the intermediary device.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If automatic registration is performed in background, then productivity is improved, but loss of information increases

Engineering Contradiction:
Improveregistration efficiencyVSAvoiduser feedback
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The system provides feedback to the user through the mobile terminal during and after the automatic registration process. The terminal displays the registration status and notifies the user when the home appliance has been successfully registered, ensuring that user feedback is maintained even though the registration process itself runs automatically in the background.

Inventive Principle:
Principle #23Feedback

AI summary

A mobile terminal according to an embodiment of the present disclosure can receive an automatic registration request for automatic registration of one of one or more home appliances displayed on an automatic registration guide screen, and display an automatic registration process screen indicating that automatic registration of the corresponding home appliance is in progress in response to the received automatic registration request.
