Solution Overview

Problem

Leather products lack flame retardancy, which can lead to the spread of fires and significant damage, necessitating the development of a composition that imparts flame retardant properties without generating toxic gases.

Innovation Solution

A composition for manufacturing leather comprising hydroxide, such as aluminum hydroxide and magnesium hydroxide, and borax, combined with liquid agents containing ceramic and titanium dioxide, is used to create a flame retardant effect, improving fire resistance and durability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional leather processing is used, then leather production is simple and cost-effective, but the leather lacks flame retardancy and can spread fire

Engineering Contradiction:

Improveflame retardancyVSAvoidcomposition complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies composite materials by combining multiple flame retardant components (hydroxide, borax, ceramic, titanium dioxide) into a unified composition that imparts flame retardancy to leather. This composite approach resolves the contradiction by achieving reliable flame protection through the synergistic effect of multiple materials rather than relying on a single substance, thereby maintaining effectiveness while managing complexity.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The patent employs parameter changes by optimizing the weight ratios of components within specific ranges (hydroxide: 0.1-5 parts, borax: 0.1-5 parts, ceramic: 1-10 parts, titanium dioxide: 1-10 parts based on 100 parts of shaving leather). By adjusting these parameters within defined boundaries, the composition achieves effective flame retardancy while controlling complexity through quantifiable formulation specifications.

Inventive Principle:

Principle #35Parameter changes

2Object-affected harmful factors

If flame retardant composition is applied to leather, then fire resistance is improved, but the processing steps and composition formulation become more complex

Engineering Contradiction:

Improvefire resistanceVSAvoidprocessing ease

Core Design Contradiction:

Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The patent applies preliminary action by incorporating flame retardant components into the leather processing composition before the leather is finished. The composition is applied during the manufacturing process (soaking, fleshing, liming, or other treatment stages) rather than as a post-processing coating, which simplifies the overall manufacturing workflow while ensuring flame retardancy is integrated into the leather structure.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent achieves universality by designing a multi-functional composition that simultaneously provides flame retardancy, smoke suppression, and potential leather treatment benefits. The same composition serves multiple purposes: hydroxide and borax provide flame retardancy, ceramic and titanium dioxide contribute to heat resistance and smoke reduction, and the formulation can be integrated with existing leather processing steps, thereby improving fire resistance without significantly complicating manufacturing.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Object-generated harmful factors

If conventional leather processing without flame retardants is used, then manufacturing is simpler, but toxic gases are generated and fire spreads rapidly

Engineering Contradiction:

Improvetoxic gas generationVSAvoidamount of composition components

Core Design Contradiction:

Object-generated harmful factorsVSQuantity of substance

Solution Approach 1:

The patent applies the blessing in disguise principle by using hydroxide and borax, which are common, relatively inexpensive substances that can be easily handled and applied. These materials convert the potential harm of complex flame retardant formulations into a benefit by providing effective toxic gas suppression and flame inhibition through readily available components, thereby reducing harmful emissions without requiring rare or highly complex substances.

Inventive Principle:

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