Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing impregnated textiles face challenges in controlling the release of active ingredients due to varying usage conditions and washing cycles, making it difficult for users to determine when re-impregnation is necessary, as current methods only account for washing conditions and not real usage conditions.

Innovation Solution

A method involving a control label on the textile with a dye that discolors proportionally to the release of active ingredients, allowing users to visually monitor depletion and decide on re-impregnation, avoiding untimely reloading and potential overdoses.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If chemical analysis after extraction is used to characterize the quantity of active ingredients, then measurement precision is improved, but device complexity and ease of operation deteriorate

Engineering Contradiction:

Improvequantity of active ingredientsVSAvoidchemical analysis equipment

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces complex chemical analysis equipment with a simple visual colorimetric test strip that changes color intensity proportional to the quantity of active ingredient, eliminating the need for extraction apparatus and chemical analyzers while maintaining measurement capability

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a colorimetric reagent as an intermediary substance that reacts with the active ingredient to produce a visible color change, serving as a bridge between the chemical composition and human observation without requiring direct chemical analysis

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If calibration based on washing conditions is implemented, then measurement precision is improved, but adaptability deteriorates

Engineering Contradiction:

Improveremaining active ingredient percentageVSAvoidreal usage conditions

Core Design Contradiction:

Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The test strip is designed to work universally across multiple usage scenarios including washing, exposure to air, and sun exposure, eliminating the need for separate calibrations for different conditions by detecting active ingredient quantity through a single colorimetric reaction

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Measurement precision

Solution Approach 1:

The system performs self-monitoring through the colorimetric test strip that automatically changes color based on active ingredient depletion, eliminating the need for the user to manually track or count washes while providing precise information about remaining active ingredient quantity

Inventive Principle:

Principle #25Self-service

4Ease of operation

If visual colorimetric test is used, then ease of operation is improved, but measurement precision deteriorates

Engineering Contradiction:

Improvevisual monitoringVSAvoidactive ingredient quantity

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The patent utilizes controlled color changes in a test strip impregnated with a colorimetric reagent that produces a visible color intensity proportional to the quantity of active ingredient present, transforming an abstract chemical measurement into a直观 visual indicator that maintains precision through calibrated color response

Inventive Principle:

Principle #32Color changes
