Solution Overview

Problem

Textile fabrics experience a loss of tensile strength during washing due to mechanical and chemical stresses, leading to potential damage and reduced lifespan, necessitating a solution that enhances fiber strength without altering the washing process.

Innovation Solution

Incorporation of alpha-substituted compounds in detergents, specifically those following the general formula R2-C(O)-CH(X)-R1, where R1 or R2 represents a straight-chain or branched alkyl group with 1 to 15 carbon atoms, and X is a functional group, to improve fiber and textile properties.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional detergents are used for washing textiles, then the washing process effectively removes dirt, but the tensile strength of textile fibers is reduced due to mechanical and chemical stresses

Engineering Contradiction:

Improvetensile strength of textile fibersVSAvoidmechanical and chemical stresses during washing

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces alpha-substituted compounds as intermediary substances that mediate between the detergent and textile fibers during washing. These compounds form protective complexes with fiber proteins (particularly wool keratin), creating a protective layer that reduces the direct impact of mechanical and chemical stresses from conventional detergents, thereby maintaining tensile strength while allowing effective washing to occur

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent converts the harmful mechanical and chemical stresses inherent in conventional washing processes into beneficial effects by using alpha-substituted compounds to enhance fiber strength. The washing process, which normally damages fibers through friction and chemical action, is transformed into a strengthening process when these compounds are present, as they form protective complexes that actually improve fiber integrity during the washing cycle

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

2Reliability

If washing frequency is reduced to preserve fiber strength, then tensile strength loss is minimized, but textile hygiene and wear removal are compromised

Engineering Contradiction:

Improvetensile strength of textile fibersVSAvoiddirt and wear accumulation on textiles

Core Design Contradiction:

ReliabilityVSLoss of substance

Solution Approach 1:

The patent enables continuous washing at normal frequencies by introducing alpha-substituted compounds that provide continuous protection to fiber strength. Rather than reducing washing frequency, the compounds ensure that each washing cycle maintains fiber integrity, allowing uninterrupted cleaning action while preserving tensile strength through the protective mechanism active throughout the washing process

Inventive Principle:

Principle #20Continuity of useful action
