Solution Overview

Problem

Conventional detergents are ineffective in removing heavy metals and formaldehyde from various materials, including clothing, household products, and indoor environments, as these pollutants often penetrate deep into fibers and surfaces, posing health risks.

Innovation Solution

A detergent composition incorporating trientine, cyclen, cyclam, and their derivatives, which form chelates with heavy metals and coordinate with formaldehyde, enhancing their removal efficacy while minimizing skin irritation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional detergents are used to remove pollutants, then general dirt and stains are removed, but heavy metals and formaldehyde remain in clothes and household products

Engineering Contradiction:

Improveremoval effectivenessVSAvoidpresence of heavy metals and formaldehyde

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the chemical parameters of the detergent by incorporating specific chelating agents (EDTA, DTPA, HEDTA, DTDMA) and oxidizing agents (percarbonate, perborate, hydrogen peroxide) in optimized concentrations. These parameter changes enable the detergent to effectively bind with and remove heavy metals and formaldehyde from fabrics and household products, transforming conventional detergent functionality.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite detergent system combining multiple functional components: chelating agents for heavy metal binding, oxidizing agents for formaldehyde decomposition, surfactants for general cleaning, and enzymes for stain removal. This composite formulation achieves synergistic effects that enable simultaneous removal of heavy metals, formaldehyde, and other contaminants.

Inventive Principle:

Principle #40Composite materials

2Reliability

If stronger chelating agents are used to remove heavy metals, then removal capability increases, but skin irritation and toxicity increase

Engineering Contradiction:

Improveheavy metal removal capabilityVSAvoidskin irritation and toxicity

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent optimizes the concentration parameters of chelating agents and oxidizing agents to achieve effective heavy metal removal while minimizing skin irritation. By controlling the dosage of active ingredients within specific ranges, the formulation maintains high removal capability while reducing harmful effects on human skin.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent introduces buffering agents and skin-conditioning ingredients as intermediary substances that moderate the potential irritant effects of strong chelating and oxidizing agents. These intermediaries allow the active ingredients to perform their heavy metal removal function while protecting the skin from excessive irritation and toxicity.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If existing detergent formulations are used, then general cleaning is effective, but fine dusts and heavy metals penetrate into fibers and are not sufficiently removed

Engineering Contradiction:

Improvecleaning efficiencyVSAvoidremoval of deeply embedded contaminants

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent modifies the chemical parameters of the detergent formulation by incorporating specific chelating agents and oxidizing agents that can penetrate fiber structures and bind with deeply embedded heavy metals and fine dusts. This parameter change enables the detergent to access and remove contaminants that conventional formulations cannot reach.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent employs strong oxidizing agents (percarbonate, perborate, hydrogen peroxide) that can accelerate the decomposition of organic contaminants and the oxidation of metal compounds within fiber structures. These oxidants penetrate deep into fabrics and household products, breaking down and removing stubborn contaminants that conventional detergents leave behind.

Inventive Principle:

Principle #38Strong oxidants (Accelerated oxidation)
