Detergent Recommendation Module for Top-Loading Washing Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Top-loading washing machines lack an effective and safe method for users to precisely determine the recommended quantity of washing products, leading to overconsumption and potential electrical hazards due to dependent light sources and complex control systems.
Innovation Solution
A standalone module for recommending the quantity of washing products, independent of the washing machine's control means, featuring a low-voltage power supply, display means, and user-friendly visual indications, allowing users to fill the detergent box up to a recommended level without electrical risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If light sources are integrated into the washing machine control system, then the recommendation function is provided, but electrical hazards and sealing complexity increase
Solution Approach 1:
The patent separates the recommendation function from the main washing machine control system by using a standalone module with independent low-voltage power supply. This segmentation isolates the electrical components, eliminating the electrical hazard risk while maintaining the recommendation functionality.
Solution Approach 2:
The patent introduces a battery-powered intermediary module that mediates between the user and the washing machine control system. This intermediary provides the recommendation function without requiring direct electrical connections to the main system, thus eliminating electrical hazards while maintaining functionality.
2Extent of automation
If light sources are controlled by washing machine control means, then automation is improved, but device complexity and sealing requirements increase
Solution Approach 1:
The patent divides the system into independent segments: the washing machine control system remains separate from the recommendation module. The module operates autonomously with its own control logic and power supply, reducing overall system complexity while maintaining automation of the recommendation function.
Solution Approach 2:
The recommendation module is designed to be self-sufficient with its own battery power supply and control logic. It does not require integration with or control from the main washing machine control means, thereby simplifying the overall device architecture while maintaining automated recommendation capabilities.
3Ease of operation
If a cup-based dosing system is used, then ease of operation is improved, but measurement precision deteriorates
Solution Approach 1:
The patent implements a visual feedback system using light sources that illuminate to indicate the recommended detergent quantity. This feedback mechanism guides the user to achieve precise dosing while maintaining simple cup-based operation, resolving the contradiction between ease of use and measurement precision.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The module provides precise and ergonomic recommendations, reducing overconsumption of washing products and minimizing environmental discharge, while ensuring user safety by avoiding electrical hazards.
Implementation Method 1
The recommendation module comprises an electrical power supply independent of the electrical power supply of the control means of the machine. In practice, the recommendation module comprises a battery
Implementation Method 2
Said at least one display means makes it possible to recommend a quantity of at least one washing product by at least one visual indication corresponding to a level of washing product to be reached

AI summary
The machine (1) has a body (2) locking a washing tank (5) that houses a rotating drum (6). A control unit (25) is placed in a control panel (13), and an access opening (3) formed in an upper portion of the body is closed by an access port (4). A recommendation module (26) recommends quantity of washing product to be introduced in a box (14) of washing product e.g. liquor, independent of the control unit of the machine. The module includes a visualization unit e.g. LEDs, for visualizing the quantity of the product to be introduced in the box.
