Laundry treating appliance and method of operation for a laundry treating appliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Laundry treating appliances lack effective mechanisms to detect and respond to dye release during cycles of operation, leading to potential color bleeding and damage to other clothes, with existing systems not providing adequate user feedback or adjustments to prevent such incidents.
Innovation Solution
Incorporating a dye sensor that outputs a signal indicative of dye presence in the treating chamber, a controller that determines dye release, and a user interface to communicate information about the dye release, including actions taken and educational feedback to prevent future occurrences, such as altering the wash cycle to reduce dye color or providing guidance on proper laundry practices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dye sensor and controller system is added to detect and respond to dye release, then the ability to protect clothes from color bleeding is improved, but the device complexity increases
Solution Approach 1:
The dye sensor continuously monitors the wash water for dye release during the wash cycle, enabling early detection before significant color bleeding occurs. The controller receives sensor signals and automatically implements protective actions such as adjusting wash parameters or extending rinse cycles, preventing damage before it happens rather than responding after the fact.
Solution Approach 2:
The system establishes a closed-loop feedback mechanism where the dye sensor continuously monitors wash water conditions and communicates with the controller. Based on detected dye levels, the controller automatically adjusts washing parameters, creates user alerts, or modifies subsequent rinse cycles. This real-time feedback enables dynamic adaptation to prevent color bleeding while maintaining system manageability through automated decision-making.
2Loss of information
If the controller provides detailed information about dye release and actions taken on the user interface, then the user feedback and education is improved, but the information complexity increases
Solution Approach 1:
The information displayed on the user interface is segmented into distinct categories: alert notifications about dye release detection, educational content about causes and prevention, and details about automatic actions taken by the controller. This segmentation allows users to process information in manageable chunks rather than receiving a single complex message, improving comprehension while maintaining comprehensive feedback.
Solution Approach 2:
Different portions of the user interface provide different types of information tailored to user needs. Critical alerts about active dye release are prominently displayed with clear call-to-action buttons, while educational prevention tips are provided in less prominent areas. This local differentiation of information quality ensures users receive appropriate levels of detail in different interface zones, reducing overall information complexity while maintaining completeness.

Function Achieved in This Case
The system effectively detects dye release, adjusts the wash cycle to minimize dye transfer, and educates users on preventing future incidents, thereby protecting clothes and enhancing user satisfaction by providing real-time feedback and preventive measures.
Implementation Method 1
a dye sensor configured to provide an output, the output indicative of an amount of dye within liquid in the treating chamber
