Packaged Shading Dye Particles for Laundry Whitening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laundry detergents with shading dyes lack flexibility and convenience in providing adjustable whitening, often resulting in excessive detergent usage and potential fabric staining.
Innovation Solution
A packaged composition comprising particles with a carrier, such as polyethylene glycol, and a shading dye, which can be used independently or incorporated into laundry detergents, providing adjustable whitening without fabric staining.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If shading dyes are incorporated into laundry detergents to provide whitening, then the whitening effect is achieved, but the consumer cannot adjust the dosage and may use excessive detergent leading to fabric staining
Solution Approach 1:
The patent segments the detergent system by providing separate components: a laundry detergent and a standalone shading dye composition. This allows consumers to use the shading dye independently or in combination with detergent, enabling precise control over whitening dosage without affecting fabric staining risk.
Solution Approach 2:
The patent enables dynamic adjustment of whitening dosage by allowing consumers to vary the amount of shading dye applied based on fabric needs. The separate packaging and labeling guide consumers on optimal dosing, making the system adaptable to different whitening requirements while preventing over-application.
2Reliability
If additional detergent is added to achieve extra whitening, then more whitening is provided, but this increases cleaning ingredient usage and fragrance deposition
Solution Approach 1:
The patent extracts the shading dye function from the detergent matrix, creating a separate shading dye composition. This allows the whitening function to be provided independently without carrying unnecessary cleaning ingredients and fragrances, eliminating waste of those components while achieving the desired whitening effect.
Solution Approach 2:
The patent applies local quality by providing targeted whitening only where needed through separate shading dye application. Consumers can apply shading dye specifically to fabrics requiring whitening without adding cleaning ingredients and fragrances to the entire laundry load, reducing unnecessary substance usage.
3Reliability
If shading dyes are used in laundry detergent, then whitening is achieved, but the color of the shading dyes dominates the overall appearance of the composition
Solution Approach 1:
The patent segments the product system into separate components: a clear or translucent laundry detergent and a separate shading dye composition with its own packaging. This eliminates the appearance dominance issue by allowing each component to maintain its aesthetic properties independently, while the labeling system provides clear visual information about usage.
