Anti-Aging Garment Laundering System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Special garments like fashion, formal, or evening wear face challenges in home laundering due to repeated washing, which can lead to loss or degradation of shape, drape, and color qualities, resulting in premature aging and potential damage, especially when using conventional laundry products that may not effectively preserve these features.
Innovation Solution
An anti-aging laundering system comprising a detergent composition, fabric rinse conditioner, ancillary laundry agent, and a fabric refresh spray, all bearing common visual indicia and instructions, which includes fabric shape retention agents, drape improvers, and color care agents, along with functionalized silicones and cationic polymers, to maintain the essential properties of fabrics during washing and extend their wear life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If home washing is used for special garments, then convenience and cost-effectiveness are improved, but shape, drape, and color qualities deteriorate over time
Solution Approach 1:
The patent combines multiple laundry functions (cleaning, shape retention, drape improvement, color care) into a single integrated home washing system using complementary products: a detergent composition for cleaning, a fabric rinse conditioner for shape and drape recovery, and ancillary agents for color protection. This merging allows consumers to maintain special garments at home while preserving their essential qualities.
Solution Approach 2:
The invention uses composite chemical formulations in each product component, combining multiple active ingredients with specific functions. The detergent contains cleaning agents tailored for delicate fabrics, the conditioner includes shape retention agents and drape improvers, and ancillary agents provide color care benefits. These composite formulations work synergistically to protect garment qualities during home washing.
2Shape
If professional cleaning service is used for special garments, then shape, drape, and color qualities are maintained, but cost and time consumption increase
Solution Approach 1:
The patent enables consumers to perform professional-grade garment care at home through self-service washing using the complementary product system. The specially formulated detergent, conditioner, and ancillary agents work together to deliver professional-quality results for shape retention, drape improvement, and color protection without requiring external professional services.
Solution Approach 2:
The home washing system is designed to provide multiple functions in a single washing cycle: cleaning soils and odors, retaining fabric shape, improving drape, and protecting color. This multi-functional approach replicates professional cleaning capabilities within the consumer home environment.
3Ease of operation
If all-in-one laundry products are used, then product selection simplicity is improved, but formulation stability and efficacy deteriorate due to chemical interactions
Solution Approach 1:
Instead of creating a single all-in-one product with potential chemical conflicts, the patent segments the laundry function into three separate but complementary products: detergent composition, fabric rinse conditioner, and ancillary laundry agent. Each product has a stable, specialized formulation optimized for its specific function, avoiding the chemical instability issues that would arise in a combined formulation while still providing simplified guidance through common visual indicia.
Solution Approach 2:
Each product in the complementary system is formulated with local quality - the detergent is optimized for cleaning with specific surfactants and enzymes, the conditioner is optimized for shape and drape with specific polymers and silicones, and the ancillary agent is optimized for color care. This localized optimization of each component's formulation ensures stability and efficacy while avoiding the chemical interactions that plague all-in-one products.
4Productivity
If harsh cleaning products are used for special garments, then cleaning performance is improved, but fabric condition deteriorates
Solution Approach 1:
The detergent composition is formulated with modified parameters suitable for delicate fabrics - using milder surfactants, lower alkalinity, and specific enzyme combinations that provide effective cleaning without the harshness of conventional detergents. The fabric rinse conditioner then applies parameter changes in the opposite direction by depositing softening agents and shape retention polymers that restore and protect fabric condition after the gentle cleaning action.
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 system ensures delicate garments undergo a complete wash cycle at home, maintaining and restoring shape, drape, and color, allowing for extended use and preventing premature aging, while preventing the need for consumers to formulate and sequence multiple products correctly.
