Solution Overview

Problem

Coffee grounds, when simply added to the production of artificial leather, result in non-uniform dispersion, leading to deteriorated mechanical strength and elongation, and pose environmental and processing challenges due to their large volume and disposal issues.

Innovation Solution

A composition for artificial leather including a first resin, a first plasticizer, and a masterbatch with coffee grounds, where the masterbatch is prepared with a second resin and second plasticizer, ensuring uniform dispersion and incorporating a biodegradation accelerator, resulting in a biodegradable and odorless product with improved mechanical properties.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If coffee grounds are simply introduced during the process of producing artificial leather, then the environmental friendliness and biodegradability are improved, but the uniformity of dispersion and mechanical strength are deteriorated

Engineering Contradiction:
Improveenvironmental impactVSAvoiduniformity of dispersion
Core Design Contradiction:
Object-affected harmful factorsVSManufacturing precision

Solution Approach 1:

The patent divides the coffee grounds into fine particles through grinding and classification processes, creating a uniform particle size distribution (D10: 10-20 μm, D50: 30-50 μm, D90: 60-80 μm). This segmentation allows the coffee grounds to disperse uniformly throughout the artificial leather matrix, resolving the contradiction between environmental benefits and dispersion uniformity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent modifies the physical and chemical parameters of coffee grounds by controlling particle size, water content (5-15%), and surface treatment. These parameter changes enable the coffee grounds to be uniformly dispersed while maintaining their biodegradable and environmentally friendly properties.

Inventive Principle:
Principle #35Parameter changes

2Object-affected harmful factors

If coffee grounds are simply introduced during the process of producing artificial leather, then the environmental friendliness and biodegradability are improved, but the mechanical strength such as tensile strength and elongation are deteriorated

Engineering Contradiction:
Improveenvironmental impactVSAvoidmechanical strength
Core Design Contradiction:
Object-affected harmful factorsVSStrength

Solution Approach 1:

The patent optimizes multiple parameters including coffee grounds particle size (fine distribution), water content (5-15%), and mixing conditions to ensure uniform dispersion. These parameter changes prevent aggregation and maintain the mechanical integrity of the artificial leather while incorporating biodegradable coffee grounds.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite material system where finely ground coffee grounds are uniformly distributed within the artificial leather matrix. This composite structure allows the coffee grounds to provide environmental benefits without compromising the overall mechanical strength, as the fine particles are well-integrated into the material structure.

Inventive Principle:
Principle #40Composite materials

3Object-affected harmful factors

If coffee grounds are simply introduced during the process of producing artificial leather, then the biodegradability is improved, but the processing cost and complexity increase

Engineering Contradiction:
ImprovebiodegradabilityVSAvoidprocessing complexity
Core Design Contradiction:
Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The patent performs preliminary actions by pre-grinding, classifying, and drying the coffee grounds before incorporation into the artificial leather production process. This preliminary preparation ensures that the coffee grounds are in the optimal state for uniform dispersion and easy processing, reducing overall manufacturing complexity while maintaining high biodegradability.

Inventive Principle:
Principle #10Preliminary action
