Laundry Appliance Auto-Dosing Control for Intensive Treatment Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current laundry appliances with multi-dose compartments fail to efficiently exploit the intensive treatment mode due to indiscriminate application and complex user interfaces, leading to confusion between auto-dosing and intensive treatment mode functionalities.
Innovation Solution
A laundry appliance with a control unit that calculates and delivers specific amounts of treatment agents based on laundry weight, selected cycle, and dirt level, allowing for a combination of auto-dosing and intensive treatment modes, simplifying user interaction through separate input selectors and automatic dose adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the same intensive treatment mode is applied indiscriminately regardless of mono-dose or multi-dose compartments, then the intensive treatment mode can be activated, but the advantages of intensive treatment are impaired due to different operative constraints
Solution Approach 1:
The patent implements dynamic adjustment of intensive treatment mode parameters based on the dosing system configuration. When multi-dose compartments are detected, the system automatically modifies treatment parameters (such as water temperature, cycle duration, or additional rinses) to account for the pre-measured doses, ensuring optimal treatment effectiveness without requiring manual user configuration.
Solution Approach 2:
The control unit receives information about the drawer configuration (mono-dose vs. multi-dose compartments) and uses this feedback to automatically adjust the intensive treatment mode parameters. This closed-loop approach ensures that the treatment mode is always appropriately configured for the specific dosing system in use, resolving the contradiction between versatility and reliability.
2Adaptability or versatility
If a complicated user interface with high number of input selectors is provided to allow selective activation of intensive treatment mode and auto-dosing functionality, then both functionalities can be controlled, but users may be confused due to the high number of input selectors
Solution Approach 1:
The patent combines the control of intensive treatment mode and auto-dosing functionality into a single integrated user interface element. Instead of separate selectors for each function, the system provides a unified interface that allows users to select treatment cycles with built-in options for both intensive treatment and auto-dosing, reducing the number of input selectors while maintaining full functionality.
Solution Approach 2:
The user interface is designed as a multi-functional selector that handles both intensive treatment mode activation and auto-dosing functionality selection within a single control mechanism. This universal interface reduces complexity by allowing one input element to control multiple related functions, eliminating the need for separate dedicated selectors for each feature.
3Ease of operation
If separate input selectors are provided for auto-dosing functionality and intensive treatment mode, then confusion between functionalities is avoided, but the device complexity increases
Solution Approach 1:
The patent resolves the contradiction by adding a logical dimension to the user interface rather than creating separate physical selectors. The interface uses hierarchical or contextual layers where the same physical selector can access different functions based on the selected treatment cycle or operational context, maintaining functional clarity without increasing physical device complexity.

AI summary
A laundry appliance having a treatment chamber and a control unit configured to perform a first set of phases of a selected treatment cycle using a dose of a treatment agent, and a treatment agent delivering device. The control unit is further configured to: receive a first command that enables the delivering device and thereupon: calculate a first amount of treatment agent, and cause the delivering device to deliver the dose to the laundry treatment chamber; and, upon receiving a second command for an intensive treatment mode: cause the laundry appliance to perform a second set of phases in addition to said first set of phases, and calculate a second amount of treatment agent when both the first and second commands are received, so that said dose comprises said first amount of treatment agent plus said second amount of treatment agent.
