Washing Machine Remote Control With Reception Feedback Confirmation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing washing machines, the use of a unidirectional wireless communication mode for setting operating information can lead to incomplete reception of user-intended operating information, potentially resulting in unintended washing operations due to the lack of confirmation mechanisms.
Innovation Solution
The washing machine incorporates a receiving part that illuminates a display part upon successful reception of operating information, allowing users to confirm receipt of settings, and includes a starting key that can switch to a standard process when the remote controller is not present, ensuring operations align with user intentions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a unidirectional wireless communication mode is adopted for setting operating information, then the communication structure is simplified and cost is reduced, but the reliability of operating information transmission deteriorates because the remote controller cannot confirm whether the operating part has received the information
Solution Approach 1:
The patent introduces a feedback mechanism where the operating part sends a response signal back to the remote controller to confirm receipt of operating information. This feedback loop allows the remote controller to verify whether the washing tank control unit has successfully received the transmitted data, thereby resolving the reliability issue while maintaining the simplified unidirectional communication structure for the primary transmission path
2Adaptability or versatility
If the operating part includes multiple keys and an information display part, then the washing operation can be controlled comprehensively, but the area occupied at the upper surface of the housing increases
Solution Approach 1:
The patent divides the control functionality into two separate parts: the operating part on the housing body and the remote controller. By segmenting the control interface, the comprehensive washing operation control capabilities are maintained in the remote controller while the operating part on the housing is minimized to essential functions only, thereby reducing the occupied area on the upper surface
3Ease of operation
If the remote controller transmits operating information without confirmation mechanism, then the operation is simple, but the risk of unintended washing operations increases due to incomplete reception
Solution Approach 1:
The patent implements a feedback confirmation mechanism where the operating part transmits a response signal to the remote controller to indicate successful reception of operating information. This feedback loop maintains operational simplicity for the user while ensuring reliability by confirming that the transmitted washing operation parameters were successfully received, preventing unintended operations

AI summary
A full-automatic washing machine includes: a first control part, a receiving part, a body display part arranged on an upper panel, and a remote controller separated from the body display part. The remote controller includes: setting keys for setting operating information of a washing operation, a second control part, an information display part and a transmitting part. The second control part displays operating information set by the setting keys through the information display part, and transmits the operating information by the transmitting part to the receiving part through wireless communication. A mode display part of the body display part is illuminated in a color such as blue corresponding to the reception of the operating information until the washing operation starts when the first control part receives the operating information.
