Detergent Box Light Guide for Precise Washing Product Dosing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current washing machines do not allow for precise visualization of the detergent quantity to be introduced, leading to suboptimal dosage recommendations based on machine parameters, resulting in variable and imprecise detergent filling.
Innovation Solution
A washing machine with a box for washing products featuring a luminous indication along its front face, allowing users to directly visualize and fill the detergent to a recommended level determined by the machine's control means, which is adaptable to the washing program, textile type, water hardness, and laundry soiling level.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If light sources are arranged on the upper face of the detergent addition device, then the device can indicate dosage information, but the user cannot directly visualize the threshold level and must use approximate cup filling
Solution Approach 1:
The patent transitions from indicating dosage information on the upper face (2D surface) to displaying it on the front face (different dimension/orientation) of the detergent box. This allows the light indication to be viewed from the front at eye level, providing direct visualization of the threshold level and enabling precise dosage measurement without relying on approximate cup filling.
2Ease of operation
If the user fills a cup and pours it into the compartment repeatedly according to light sources, then the device can indicate dosage quantity, but the dosage becomes variable and imprecise depending on cup filling
Solution Approach 1:
The patent implements a feedback mechanism where light sources on the front face of the detergent box illuminate to indicate the precise threshold level that should be reached. This visual feedback allows the user to directly fill the detergent to the indicated level in a single operation, eliminating the need for repeated cup pouring and providing both ease of operation and precise dosage control.
3Loss of information
If transparent windows are used to indicate filling level, then the device can show detergent quantity, but it cannot provide active guidance on the threshold to be reached
Solution Approach 1:
The patent introduces light sources as an intermediary element between the detergent box and the user. These light sources actively illuminate to indicate the recommended threshold level, serving as a mediator that provides clear guidance on the precise dosage to be reached. This enhances both the visibility of the filling level and the ease of operation by giving active directional guidance.
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
Enables precise and ergonomic detergent dosage, preventing overdosing by providing real-time visual feedback and ensuring the recommended detergent level is reached, optimizing detergent use based on specific laundry conditions.
Implementation Method 1
the box for washing products comprises at least one luminous means disposed on said front face, said at least one luminous means making it possible to recommend a quantity of washing product to be introduced into said box for washing products by at least one light indication

A unit to indicate a quantity of cloths to be washed during filling of the case, a hardness of water, and a type of the cloth. The luminous indication is arranged along a vertical axis (24) of front side of the case, and is placed along a transparent window (29) to visualize the level of cloths introduced into the case for washing. The luminous indication extends from a minimum level up to a level of indication of the quantity of cloths to be washed during the filling of the case, where the case is integrated in a lid. The front side of the case is placed on an internal side of the lid. The luminous indication is visible during an opening of the lid. Two compartments of the case are associated with the luminous unit, which has light sources and a light-guide.
