Four-Component Liquid Washing Composition for Fabric-Specific Dosing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laundry detergents often require multiple products for different fabric types, leading to complexity, inefficiency, environmental waste, and potential damage to delicate fibers, while machines with multiple tanks face inefficiencies and space constraints.
Innovation Solution
A liquid washing composition divided into four separate components, each optimized for specific fabric types and conditions, with enzymes stabilized in a single container and surfactants separated based on temperature activity, used in a machine with automatic dosing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate detergent products are used for different fabric types, then washing effectiveness for specific fabrics is improved, but product complexity and storage space requirements increase
Solution Approach 1:
The detergent composition is divided into separate functional modules: a first detergent composition for delicate fabrics and a second detergent composition for robust fabrics. Each module contains specific surfactants and additives optimized for its target fabric type, allowing selective application based on fabric requirements while maintaining overall system simplicity
Solution Approach 2:
The invention creates a universal washing system where a single detergent package contains multiple fabric-type compositions. The system can adapt to different fabric requirements (delicate, robust, mixed) within one product unit, eliminating the need for consumers to purchase and manage multiple separate detergent products
2Device complexity
If all-purpose detergent is used for all fabric types, then product simplicity is maintained, but washing effectiveness for delicate fabrics deteriorates due to excessive detergent and bleaching
Solution Approach 1:
The detergent is segmented into at least two distinct compositions within a single package: a first composition with lower detergent and bleach content for delicate fabrics, and a second composition with higher detergent and bleach content for robust fabrics. This segmentation allows each fabric type to receive appropriately dosed treatment without compromising simplicity
Solution Approach 2:
Different regions or portions of the detergent system are assigned different chemical properties and concentrations. The first detergent composition has mild properties suited for delicate fabrics, while the second has strong properties for robust fabrics, allowing localized optimization without requiring separate products
3Adaptability or versatility
If multiple detergent products are purchased and stored, then washing requirements for different fabrics are met, but storage space and management complexity increase
Solution Approach 1:
Multiple detergent compositions that would traditionally require separate containers are merged into a single integrated detergent package. The package contains both the first detergent composition (for delicate fabrics) and the second detergent composition (for robust fabrics), along with mechanisms for selective application, thereby consolidating storage requirements while maintaining versatility
Solution Approach 2:
A single detergent product performs multiple functions by containing compositions for different fabric types. The system can handle delicate fabrics, robust fabrics, and mixed loads within one product, replacing the need for multiple separate detergent products and reducing storage space
4Reliability
If high detergent concentration is used for robust fabrics, then washing power is improved, but environmental impact increases due to unnecessary overdosing
Solution Approach 1:
The detergent system dynamically adjusts the concentration and type of surfactants and additives based on the fabric type being washed. For delicate fabrics, lower concentrations are used; for robust fabrics, higher concentrations are deployed. This dynamic adaptation ensures optimal washing power while minimizing environmental impact by avoiding unnecessary overdosing
5Adaptability or versatility
If multiple surfactants are included for different temperature ranges, then washing effectiveness across temperatures is improved, but formulation complexity and waste increase
Solution Approach 1:
The surfactant system is segmented into different compositions optimized for different temperature ranges. The first detergent composition contains surfactants suited for lower temperatures and delicate fabrics, while the second contains surfactants optimized for higher temperatures and robust fabrics. This segmentation allows temperature-appropriate surfactant selection without requiring a single complex universal formulation

AI summary
A fluid washing composition with four separate components and laundry washing kit thereof is disclosed. The four components are housed in respective independent tanks of a laundry washing machine equipped with a program for selecting, dosing and differentiated delivering. Component 1 is a detergent formulation with a pH of 4.0-12.0, with high detergent effect in washing programs at temperatures of 40°-60° C., having a specific action on cotton fibers, particularly, whites. Component 2 is a detergent formulation with a pH of 8.0-12.0, with high detergent effect in washing programs at temperatures of 15°-40° C., having a specific action on synthetic, colored and animal-origin fibers. Component 3 is an enzyme-based stain-removing formulation including protease and lipase and possibly amylase with a pH of 5.0-6.0, stabilized with sorbitol and calcium chloride. Component 4 is an after-wash conditioning formulation, with a pH of 2.0-4.0.
