Laundry Processing Device Remote Control via Door Lock State Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote controllable laundry processing devices cannot be controlled through an external terminal when the remote control is not set or released, limiting user convenience, especially when users want to make changes like adding additional clothes during operation.
Innovation Solution
A laundry processing device with a sensor unit to detect the door's locked state, a manipulation unit for user input, a remote control setting unit, and a communication unit that allows control via an external terminal or voice signals, enabling control regardless of the remote control's setting status when the door is locked.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote control is not set, then manipulation unit control is available, but external terminal control is impossible
Solution Approach 1:
The patent makes the door lock state the universal condition that determines control accessibility. Regardless of whether remote control is pre-set, when the door is locked during operation, the external terminal automatically gains control capability. This multi-functional approach allows the system to serve both local users (via manipulation unit) and remote users (via external terminal) under different conditions, resolving the contradiction between local control availability and remote control capability.
2Reliability
If door is locked during operation, then laundry processing is secure, but control flexibility is reduced
Solution Approach 1:
The patent introduces the door lock state as an intermediary condition that mediates between security requirements and control flexibility. The lock state triggers automatic switching of control modes, allowing the system to maintain security through locked door status while simultaneously enabling flexible control through external terminal access. This intermediary mechanism resolves the contradiction by using the lock state itself as the trigger for enhanced remote control capability.

AI summary
A remote controllable laundry processing device (100) and a control method thereof are disclosed. The remote controllable laundry processing device includes a cabinet main body (211) including a door (215); a sensor unit (150) sensing a locked state of the door; a manipulation unit (120) provided for user input; a remote control setting unit (121) performing control of the laundry processing device based on an external terminal; a controller (130) controlling an overall operation of the laundry processing device; and a communication unit (160) sending a signal input through the external terminal to the controller. When the door is in the locked state, the controller controls the laundry processing device in response to a first input signal input through the manipulation unit and a second input signal input through the external terminal, regardless of whether or not a remote control has been set by the remote control setting unit.
