Solution Overview

Problem

Clothes age prematurely due to various external factors such as washing and wear, leading to a need for products that can extend their lifespan and reduce environmental impact by minimizing the frequency of new purchases.

Innovation Solution

A serum comprising 1 to 60 wt% lubricant, with less than 4 wt% surfactant, used in conjunction with laundry detergent and/or fabric conditioner, which floats on the laundry liquid to provide anti-aging benefits by preventing fabric aging through the use of silicone-based lubricants and cationic polymers, ensuring maximum performance without mixing with the laundry liquid.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of stationary object

If conventional laundry products are used, then clothes undergo normal washing and conditioning, but clothes age prematurely due to stretching, fading, bobbling, and loss of shape

Engineering Contradiction:
Improvelifespan of clothesVSAvoidfabric aging factors
Core Design Contradiction:
Duration of action of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the lubricant component from traditional fabric conditioner formulations, creating a dedicated serum product with high lubricant content (1-60 wt%) and low surfactant content (<4 wt%). This extraction allows the lubricant to perform its anti-aging function without interference from other ingredients, directly addressing fabric aging factors like stretching and loss of shape.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent changes the compositional parameters by significantly increasing lubricant concentration (1-60 wt%, much higher than conventional conditioners) and reducing surfactant content (<4 wt%). This parameter change transforms the product from a typical fabric conditioner into a specialized serum that prioritizes lubrication and anti-aging benefits over detergency and foam generation.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If multiple fabric care benefits are provided through complex multi-phase compositions, then various fabric care functions are achieved, but the composition becomes complex and difficult to use

Engineering Contradiction:
Improvefabric care benefitsVSAvoidcomposition complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent creates a universal serum composition where a single product delivers multiple fabric care benefits: anti-aging (preventing stretching and loss of shape), softening (through lubricant action), and fabric protection. The simple two-component formulation (lubricant + minimal surfactant) achieves these diverse functions without requiring complex multi-phase compositions.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

Instead of starting with a complex multi-phase composition and trying to achieve multiple benefits, the patent inverts the approach by starting with a simple base of lubricant and minimal surfactant, then adding optional complementary ingredients. This inversion simplifies the formulation while maintaining versatility.

Inventive Principle:
Principle #13The other way round (Inversion)
