Solution Overview

Problem

Existing stain removal devices, such as water-soluble pouches, often dilute cleaning compositions, reducing their effectiveness and requiring multiple wash cycles, which increases costs and damages clothing due to repeated washing and scrubbing.

Innovation Solution

A stain removal device with a shell that surrounds the stain, containing a dispensable cleaning agent encapsulated in a water-soluble pod, which is secured to the fabric using magnets or other fasteners, allowing targeted release of the cleaning agent during a wash cycle, avoiding fabric damage and excess product consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If water-soluble pouches are placed in the wash basin, then cleaning composition is released, but the cleaning composition is diluted and effectiveness decreases

Engineering Contradiction:
Improveconcentration of cleaning compositionVSAvoideffectiveness of stain removal
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The patent applies local quality by concentrating the cleaning composition in a localized shell that directly contacts the stain, rather than dispersing it throughout the entire wash basin. The shell contains the cleaning composition in a concentrated form and releases it locally at the stain site, maintaining high effectiveness while avoiding dilution in the bulk water.

Inventive Principle:
Principle #3Local quality

2Reliability

If multiple wash cycles are used to remove stains, then stain removal may be achieved, but costs increase and fabric integrity decreases

Engineering Contradiction:
Improvestain removal effectivenessVSAvoidnumber of wash cycles required
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-positioning the cleaning composition directly on the stain before the wash cycle begins. The shell is attached to the stained fabric area in advance, and the cleaning composition is released during the wash cycle, allowing stain removal to occur more effectively and potentially in a single cycle rather than requiring multiple repetitions.

Inventive Principle:
Principle #10Preliminary action

3Area of stationary object

If cleaning composition is dispersed in the wash basin, then coverage is increased, but concentration at the stain site decreases

Engineering Contradiction:
Improvecoverage areaVSAvoidconcentration of cleaning agent
Core Design Contradiction:
Area of stationary objectVSQuantity of substance

Solution Approach 1:

The patent resolves this contradiction by making the cleaning system mobile and adaptive rather than stationary. The shell can be positioned at different locations on the fabric to target specific stains, and it releases the cleaning composition locally at high concentration precisely where needed, rather than dispersing a diluted solution over a large area.

Inventive Principle:
Principle #3Local quality
