Cloud-Authenticated Home Appliance Control for Secure Remote Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional home appliance control systems are limited in functionality, insecure, and require manual operation, lacking flexibility and ease of use, with risks of unauthorized access and misuse.
Innovation Solution
A home appliance control system connected to the Internet via a gateway, utilizing a home appliance control cloud and a separate control command supply cloud, where control commands are authenticated and executed only from predefined servers, enabling secure and efficient operation through cloud-based instruction sets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If home appliance is connected to wireless network for remote control, then ease of operation is improved, but security and reliability deteriorates due to risk of unauthorized access and misuse
Solution Approach 1:
The patent introduces a gateway device as an intermediary between the home appliance and the wireless network. The gateway authenticates incoming control requests and forwards only validated commands to the appliance, preventing direct unauthorized access while maintaining remote control functionality. This mediator layer resolves the contradiction by enabling ease of operation through remote access while preserving security through centralized authentication.
2Device complexity
If conventional user interface with buttons and touchscreen is used, then device complexity is minimized, but ease of operation deteriorates due to manual control requirements
Solution Approach 1:
The patent enables the home appliance to execute pre-configured control sequences automatically based on user selections made through the interface. Instead of requiring manual step-by-step control, the user selects a desired operation mode and the appliance autonomously executes the corresponding control commands, reducing manual effort while maintaining interface simplicity.
3Ease of operation
If remote control functionality is enabled via wireless network, then ease of operation is improved, but device complexity increases due to additional communication infrastructure
Solution Approach 1:
The patent divides the control system into separate functional components: the home appliance, the gateway device, and the control interface. The gateway handles all complex communication protocols and network infrastructure, while the appliance itself remains relatively simple. This segmentation allows remote control functionality to be added without significantly increasing the complexity of the appliance device itself.

AI summary
A method of controlling a home appliance connected to the Internet via a gateway and an appliance control server of an appliance control cloud. The appliance executes control commands for operating the appliance received from the Internet via the gateway only if the commands are received from the appliance control cloud. A control command supply server of a control command supply cloud is connected to the home appliance control cloud via the Internet, and has at least one repository storing control instruction sets to operate the appliance. The method includes authenticating a request for remote control of the appliance received from the control command supply server via the Internet, and, responsive to positive authentication, forwarding control commands from the control command supply server to the appliance. The control commands are part of a set of instructions from the repository selected based on input received by a user terminal device.
