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 user preferences and laundry characteristics.
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 update settings accordingly, allowing for customizable operation modes based on detected configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a sensor system is added to detect agitator presence, then adaptability of the washing machine is improved, but device complexity increases
Solution Approach 1:
The system automatically detects the agitator configuration using the sensor and processor, then self-adjusts the washing cycle parameters without user intervention. The controller autonomously determines whether to use high-efficiency or standard washing parameters based on the detected agitator presence, making the system adapt to different configurations automatically.
Solution Approach 2:
The patent replaces manual configuration selection with an automated sensor-based detection system. Instead of requiring users to manually select washing modes or physically configure the agitator, the system uses optical or proximity sensors to automatically detect agitator presence and electronically adjusts the washing parameters through the processor and controller.
2Measurement precision
If hardware detection is implemented to identify agitator configuration, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent extracts the detection function into a separate, dedicated sensor component rather than integrating it into the existing motor or control system. This modular approach allows for precise agitator detection while keeping the core washing mechanism simple and maintains ease of manufacture.
Solution Approach 2:
The sensor acts as an intermediary between the physical agitator configuration and the electronic control system. It converts physical presence into detectable signals that the processor can interpret, enabling precise measurement of agitator configuration without directly complicating the mechanical washing system.
3Ease of operation
If the system automatically updates settings based on sensor data, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The system performs self-configuration by automatically detecting the agitator presence and adjusting washing parameters without requiring user input. The controller autonomously selects the appropriate washing mode (high-efficiency or standard) based on sensor data, eliminating the need for users to understand or manually configure technical parameters.
Solution Approach 2:
The system implements a feedback loop where the sensor continuously monitors agitator presence and feeds this information to the processor, which then adjusts the washing cycle parameters in real-time. This closed-loop control ensures the washing machine operates optimally for the detected configuration without user intervention.
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.
