Solution Overview

Problem

Existing methods for registering electrical apparatuses in a network system require users to input identification information from a mobile terminal, making the process inconvenient due to the need for keyboard representation and input functions.

Innovation Solution

A remote control system that includes a terminal device, a server device, and an electrical apparatus, where the terminal device transmits an encrypted apparatus ID to the electrical apparatus, which then sends server transmission data to the server device for registration, allowing the apparatus to be registered without user input of identification information on the mobile terminal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the user inputs identification information from a mobile terminal to register an electrical apparatus, then the registration process can be performed, but the operation becomes inconvenient due to the need for keyboard representation and input functions

Engineering Contradiction:

Improveregistration accuracyVSAvoidinput convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The electrical apparatus automatically transmits its own identification information to the terminal device and server device without requiring user input. The apparatus serves itself by generating and sending the ID automatically, eliminating the need for manual keyboard input while ensuring accurate registration.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The terminal device acts as an intermediary that receives identification information automatically from the electrical apparatus via communication, then transmits it to the server device. This mediator approach eliminates direct user input requirements while maintaining the registration process integrity.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the apparatus ID is transmitted in plaintext, then the registration process is simple, but security is compromised

Engineering Contradiction:

Improveregistration simplicityVSAvoidsecurity risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The identification information is transformed from plaintext to encrypted format using encryption processing. The encrypted ID is transmitted between devices and the server, maintaining security while allowing the registration process to proceed. The server device decrypts and verifies the encrypted ID to complete registration.

Inventive Principle:

Principle #35Parameter changes

AI summary

A remote control system includes an electrical apparatus, a terminal device, and a server device. The terminal device receives a first encrypted apparatus ID in which an apparatus ID is encrypted from the electrical apparatus. The terminal device transmits the first encrypted apparatus ID to the electrical apparatus. The electrical apparatus transmits the apparatus ID and the first encrypted apparatus ID to the server device. The terminal device transmits the first encrypted apparatus ID to the server device. The server device determines whether there is a match in the first encrypted apparatus ID received from the electrical apparatus or the terminal device. When there is a match, the server device registers the apparatus ID in a first security state.
