Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current remote control methods for washing machines lack safety measures, allowing unauthorized access and potential accidents due to the inability to verify the machine's state and surrounding conditions, leading to safety hazards.
Innovation Solution
A remote control method that establishes a status feedback channel between the washing machine and a mobile terminal, requiring activation of a key to establish a control channel, ensuring the machine is in a safe state before allowing remote control, including checks for door closure, lock status, and operational state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote control is enabled without safety verification, then ease of operation is improved, but safety and reliability deteriorate due to unauthorized access and unsafe states
Solution Approach 1:
The system performs preliminary safety verification before enabling remote control. The activation key must be pressed locally to confirm the washing machine is in a safe state (door closed, lock engaged, no ongoing cycles) before the control channel is established. This preliminary action prevents unauthorized or unsafe remote operations.
Solution Approach 2:
The activation key serves as an intermediary mechanism between the local user and the remote control system. It mediates the authorization process by requiring local confirmation that safety conditions are met before allowing remote control instructions to be executed, thus bridging the gap between convenience and safety.
2Reliability
If activation key and safety checks are implemented, then safety and reliability are improved, but device complexity increases due to additional verification steps
Solution Approach 1:
The safety verification logic is extracted from the main control system and implemented as a separate, dedicated activation key mechanism. This extraction simplifies the overall system by isolating the safety check function into a distinct component that operates independently from the complex remote control processing, making the system easier to manage despite added safety features.
Solution Approach 2:
The activation key system is self-contained and automatically verifies safety conditions (door status, lock status, cycle state) without requiring complex external verification systems. The washing machine's own sensors and status indicators serve the verification function, eliminating the need for additional complex external safety mechanisms.
3Object-affected harmful factors
If multiple safety verification steps are performed, then object-affected harmful factors are reduced, but loss of time increases due to additional verification steps
Solution Approach 1:
The system replaces complex mechanical safety verification mechanisms with electronic sensing and digital logic. Microprocessors and sensors automatically check safety conditions (door switches, lock sensors, cycle detectors) in milliseconds, substituting what would otherwise require manual verification steps and significantly reducing the time penalty while maintaining comprehensive safety checks.
Solution Approach 2:
The system uses real-time feedback from sensors monitoring door status, lock engagement, and cycle state to automatically determine whether safety conditions are met. This continuous feedback loop allows the activation key to instantly verify safety without manual intervention, reducing activation time while ensuring all harmful factors are checked.

AI summary
The present disclosure discloses a remote control method for a washing machine, a washing machine and a mobile terminal in wireless connection with the washing machine are used, and the remote control method includes the following steps: a status feedback channel that is between the washing machine and the mobile terminal and that is configured to transmit a working status of the washing machine is established; a control request sent by the mobile terminal is received by the washing machine; and after an activation key disposed on the washing machine is activated, a control channel that is between the washing machine and the mobile terminal and that is configured to transmit a control instruction is established. The remote control method for a washing machine disclosed in the present disclosure, solves the safety problem of the remote control of the washing machine. The control channel that is between the washing machine and the mobile terminal and that is configured to transmit a control instruction can be established only when a person who controls the washing machine in advance pre-ensures that the washing machine is in a safe state or another person ensures that the washing machine is in a safe state, and further triggers the activation key, thereby implementing remote control of the washing machine. The remote control method of the present disclosure improves the running safety of the washing machine.
