Remote Control Terminal Network Discrimination for Appliance Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control systems for home electric appliances lack the ability to discriminate between communication networks and provide permission/rejection of operations based on the network type, leading to potential unsafe situations when users attempt to control appliances remotely without being present.
Innovation Solution
A remote control terminal and server system that discriminates between local area and wide area communication networks, allowing permission/rejection of operation instructions based on network type, ensuring safe operation of appliances by verifying user presence through network connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote control operation is allowed via wide area communication network when user is outside home, then user convenience is improved, but safety risk increases due to inability to respond to dangerous conditions
Solution Approach 1:
The patent introduces a gateway device as an intermediary between the mobile terminal and the home electric appliance. The gateway discriminates between local area network (LAN) and wide area network (WAN) communication and controls operation permission accordingly. When connected via LAN (user present), operations are permitted; when connected via WAN (user absent), operations are rejected. This intermediary resolves the contradiction by enabling convenient remote control through WAN while maintaining safety through intelligent network-type-based permission control.
2Measurement precision
If multiple dedicated remote controllers are used for each home electric appliance, then control precision is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal remote control system where a single mobile terminal can control multiple different home electric appliances through the gateway device. The gateway maintains communication records associating different mobile terminals with different appliances and handles the appropriate communication protocols for each appliance type. This eliminates the need for multiple dedicated remote controllers while maintaining precise control over each appliance.

AI summary
A mobile terminal 1A is configured to communicate with a remote control server 4A that transmits a remote control signal to operate an operation object apparatus via a particular local area network NW2 or a wide area communication network NW1. A permission/rejection information storage part 102 stores whether execution of remote control operation based on the operation instruction information is permitted or rejected when each operation instruction information has gone through any communication network. When receiving the input of operation instruction information, a communication network discrimination part 106 discriminates with which communication network communication has established. An operation permission/rejection decision part 107 decides permission/rejection of execution of the operation instruction information according to the results. When remote control operation based on operation instruction information is permitted as a result of decision, operation instruction information is transmitted to the remote control server 4A.
