Remote Control System Communication Interruption Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control systems for home appliances fail to properly manage appliances when network communication is interrupted, leading to undesirable prolonged operations.
Innovation Solution
A remote control system with a home appliance and a relay device that detects communication interruptions on multiple communication lines, using detectors and transmitters to manage the appliance's state based on interruption duration, ensuring proper management and preventing unnecessary operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the appliance continues operating according to pre-interruption instructions during network communication interruption, then the appliance maintains its operational function, but the appliance operates unnecessarily for extended time causing energy waste and potential safety issues
Solution Approach 1:
The system implements feedback by having the appliance detect communication interruption status and send this information back to the relay device. The relay device then provides feedback about the interruption duration, enabling the appliance to adjust its operation based on real-time communication status, preventing unnecessary energy consumption during prolonged interruptions.
Solution Approach 2:
The system performs preliminary action by establishing communication interruption detection and duration tracking before the interruption causes significant energy waste. The appliance proactively monitors communication status and prepares to adjust its operation in advance, rather than continuing operation until energy depletion or safety issues occur.
2Loss of energy
If the appliance detects communication interruption and changes state based on interruption duration, then energy waste is prevented, but the system complexity increases due to multiple detectors and state management mechanisms
Solution Approach 1:
The system merges the communication interruption detection function into the existing appliance controller rather than adding separate dedicated hardware detectors. The relay device utilizes its existing communication management capabilities to track interruption duration, combining multiple functions into existing components and reducing overall system complexity.
Solution Approach 2:
The relay device performs multiple functions: it acts as a communication gateway, a communication interruption detector, a duration timer, and a state management coordinator. By making the relay device universal and multi-functional, the system avoids adding separate specialized components for each function, thereby reducing system complexity while maintaining energy efficiency.

AI summary
A remote control system (100) includes a home appliance (10) and a relay device (20, 30) for relaying transmission of an operation instruction for controlling the home appliance (10). The home appliance (10) includes a first detector for detecting a communication interruption on a first communication line (41, 42) for transmission of the operation instruction from the relay device (20, 30) to the home appliance (10), a receiver for receiving, from the relay device, an interruption signal indicating a communication interruption on a second communication line (42, 43) for transmitting the operation instruction from a communication device to the relay device (20, 30), and a state changer for changing a state of the home appliance in accordance with a duration of at least one of the communication interruption detected by the first detector or the communication interruption indicated by the interruption signal. The relay device (20, 30) includes a second detector for detecting the communication interruption on the second communication line (42, 43), and a transmitter for transmitting the interruption signal to the home appliance (10) when the communication interruption is detected by the second detector.
