Laundry Appliance Agitator Detection for Adaptive Cycle Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Laundry treating appliances lack an effective method to detect the presence or absence of a removable agitator, which affects the customization and optimization of washing cycles based on the agitator configuration, leading to suboptimal cleaning performance.
Innovation Solution
A system with a sensor configured to provide data on the presence or absence of a removable agitator, with a processor communicating with the sensor to identify the configuration and update settings accordingly, allowing for customized operation based on the detected agitator configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the laundry treating appliance uses a fixed washing cycle configuration, then the device complexity is reduced, but the adaptability to different agitator configurations is worsened
Solution Approach 1:
The washing cycle configuration is made dynamic and adaptive rather than fixed. The controller automatically adjusts cycle parameters based on real-time detection of agitator presence and configuration, allowing the system to adapt to different agitator types (removable or fixed) without requiring manual user input or complex pre-programming for each scenario.
Solution Approach 2:
The system performs self-detection and self-adjustment of cycle parameters. The sensor automatically detects the agitator configuration and the controller autonomously modifies the washing cycle settings without user intervention, eliminating the need for users to manually select or configure cycles based on their agitator type.
2Device complexity
If the laundry treating appliance lacks agitator detection capability, then the device complexity is reduced, but the cleaning performance is worsened
Solution Approach 1:
The patent replaces complex mechanical detection systems with simpler sensor-based detection. Instead of using mechanical switches, physical contacts, or complex mechanical linkages to detect agitator presence, the system uses optical, capacitive, or other non-contact sensors that provide reliable detection with minimal mechanical components.
Solution Approach 2:
The system implements a feedback loop where sensor data about agitator configuration is continuously monitored and used to adjust washing cycle parameters in real-time. This closed-loop control ensures that the cleaning performance is optimized for the detected agitator type, with the controller automatically modifying agitation intensity, water flow, and cycle duration based on sensor feedback.
Data Source
AI summary
Hardware detection in a laundry treatment appliance is provided. Data is received from the sensor providing data in relation to presence or absence of a removable agitator within the laundry treatment appliance. A configuration of the removable agitator with respect to the laundry treatment appliance is identified based on the data from the sensor, the configuration indicating at least the presence or absence of the removable agitator. Settings of the laundry treatment appliance are updated in accordance with the identified configuration of the laundry treatment appliance.
