Remote control method for washing machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control methods for washing machines lack safety measures, as they cannot accurately assess the status of the washing machine and its environment, leading to potential safety accidents when remotely operated.
Innovation Solution
A remote control method that establishes a control channel and a status feedback channel between a mobile terminal and a washing machine, where the status information is checked against preset conditions before allowing remote control, ensuring the washing machine is in a safe state before operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote control is enabled without status verification, then ease of operation is improved, but safety and reliability deteriorate
Solution Approach 1:
The system performs preliminary status verification before enabling remote control operations. The control channel remains closed until the washing machine confirms it is in a safe state for remote operation, preventing unsafe controls while maintaining convenience when conditions are met
Solution Approach 2:
The washing machine continuously monitors its operational status and provides feedback to the mobile terminal. The control channel is dynamically opened or closed based on real-time status verification, ensuring remote control is only enabled when safe conditions are confirmed
2Reliability
If status verification is implemented before remote control, then safety is improved, but device complexity increases
Solution Approach 1:
The washing machine's control unit acts as an intermediary that automatically verifies status conditions and manages the control channel. This intermediary function handles the complexity of status verification internally, presenting a simple interface to users while ensuring safety through automated checks
3Productivity
If control channel is maintained without status checking, then productivity is improved, but harmful factors increase
Solution Approach 1:
The system applies preliminary anti-action by preemptively closing the control channel when unsafe conditions are detected. This prevents harmful operations before they can occur, maintaining productivity when safe while blocking harmful factors when conditions deteriorate

AI summary
A remote control method for a washing machine includes the following steps: establishing, between a mobile terminal and the washing machine, a control channel used to transmit a control instruction and a status feedback channel used to transmit a working status of the washing machine; obtaining status information of the washing machine; and when the status information does not match preset information by which the mobile terminal remotely controls the washing machine, cutting off the control channel, and maintaining the status feedback channel. When the washing machine is remotely controlled by the mobile terminal, corresponding state conditions are controlled in a centralized manner, preset information by which the mobile terminal is allowed to remotely control the washing machine is formed, and then it is determined whether real-time status information of the washing machine matches the preset information, so that safety of the remote control method is improved.
