Dual-Path Appliance Control for Low-Latency Remote Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional control systems for household electrical appliances, such as air conditioners, experience delays and congestion issues when controlling devices via mobile terminals due to internet congestion, making it difficult for users to control appliances stress-free.
Innovation Solution
A control system that allows users to select between direct communication through a router device or communication through the internet and router device, enabling stress-free control by choosing the most suitable method based on location, with a mobile terminal connected to a router device and an internet, and a relay device that relays communication between the mobile terminal and the household appliance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If communication is performed through the internet and relay device, then remote control capability is achieved, but response delay and congestion occur
Solution Approach 1:
The system dynamically switches between two communication modes: Wi-Fi Direct mode for low-latency local control and Internet relay mode for remote control. The mobile terminal can select the appropriate communication path based on whether the user is inside or outside the house, making the system adaptable to different usage scenarios while optimizing response time for each scenario.
2Adaptability or versatility
If internet communication is used for appliance control, then remote access is enabled, but system reliability decreases due to congestion
Solution Approach 1:
The relay device acts as an intermediary that enables remote access through Internet communication while maintaining a separate direct Wi-Fi Direct communication path. This dual-path architecture allows the system to use the relay device for remote access without compromising the reliability of local control, as each communication method operates independently.
3Speed
If only direct router communication is used, then fast local control is achieved, but remote control capability is lost
Solution Approach 1:
The mobile terminal is designed with multi-functionality to support both Wi-Fi Direct communication for fast local control and Internet relay communication for remote control. The terminal can universally operate in either mode depending on the user's location and needs, making the control system versatile without sacrificing the speed benefits of direct communication.

AI summary
A control system 10 for controlling a household electrical appliance 12 has a router device 26 connected to an internet, a mobile terminal 16 sending a control signal for controlling the household electrical appliance12, a communication device 14 connected to the household electrical appliance 12 and receiving the control signal, and a relay device 18 connected to the router device 26 and relaying communication between the communication device 14 and the mobile terminal 16. The mobile terminal 16 and the relay device 18 are adapted to have a first communication between the mobile terminal 16 and the relay device 18 only through the router device 26 and a second communication between the mobile terminal 16 and the relay device 18 through the internet 20 and the router device 26. The mobile terminal 16 is adapted to enable a user to select the first or second communication by the use of the mobile terminal 16.
