Laundry treatment apparatus and method of controlling same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laundry treatment apparatuses face challenges in enabling remote control without violating safety standards, such as those set by the International Electrotechnical Commission (IEC), particularly when continuous remote control is maintained after a washing cycle is completed, which can lead to safety hazards like unauthorized access.
Innovation Solution
A laundry treatment apparatus and control method that allows for remote control of a washing cycle to continue after completion, ensuring compliance with safety standards by requiring manual input to re-allow remote control and incorporating a door lock mechanism that secures the apparatus during operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote control is continuously maintained after washing cycle completion, then user convenience is improved, but safety standards are violated
Solution Approach 1:
The control unit automatically maintains the remote control permission state without requiring user re-input, anticipating the user's need for continuous remote control while preemptively addressing safety concerns through automatic state management. This preliminary action ensures both convenience and compliance by setting the system in advance to handle remote control permissions appropriately after cycle completion.
2Reliability
If remote control is released after use, then safety standards are satisfied, but user convenience deteriorates
Solution Approach 1:
The system dynamically adjusts the remote control permission state based on the washing cycle status. During the cycle, remote control is permitted; after completion, the permission is automatically maintained rather than released. This dynamic behavior allows the system to adapt to different operational phases, ensuring safety during operation while providing convenience after completion without requiring manual user intervention.
3Reliability
If door lock is released when remote control is completed, then safety is improved, but risk of unauthorized access increases
Solution Approach 1:
The control unit continuously monitors the remote control permission state and automatically maintains the door lock state corresponding to the current operational context. When remote control permission is active, the door remains locked; when permission is revoked, the door lock state is adjusted accordingly. This feedback mechanism ensures that door lock status always reflects the current security requirements, preventing unauthorized access while maintaining safety.
