Solution Overview

Problem

Current biodegradable plastics face challenges in maintaining physical strength and structural characteristics while degrading, and existing solutions are often costly and not fully environmentally friendly, with incomplete solutions for pollution from plastic waste.

Innovation Solution

Incorporating natural peptides, enzymes, and proteins from edible sources into petroleum-based polyolefin polymers, such as polyethylene, to create a biodegradable, compostable, and digestible plastic formulation that retains mechanical properties and is cost-effective, using a process that blends these additives with polyolefin polymers at specific temperatures to enhance biodegradability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If starch is incorporated into biodegradable plastic to improve degradability, then biodegradability is improved, but physical strength and structural characteristics deteriorate

Engineering Contradiction:

ImprovebiodegradabilityVSAvoidphysical strength

Core Design Contradiction:

ReliabilityVSStrength

Solution Approach 1:

The patent creates a composite material system combining polyethylene polymer with peptide-enzyme-protein composition. This composite structure allows the hydrophobic polyethylene matrix to maintain physical strength while the hydrophilic peptide-enzyme-protein components provide biodegradability pathways, resolving the contradiction between strength and degradability

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The patent applies local quality by creating distinct regions within the plastic material: the polyethylene polymer provides structural integrity and mechanical strength in the matrix, while the peptide-enzyme-protein composition creates localized hydrophilic regions that enable biodegradation. This spatial differentiation allows simultaneous achievement of strength and degradability

Inventive Principle:

Principle #3Local quality

2Speed

If photodegradable or oxo-degradable additives are introduced to accelerate degradation, then degradation rate is improved, but detrimental properties are introduced to the polymer products

Engineering Contradiction:

Improvedegradation rateVSAvoidpolymer product properties

Core Design Contradiction:

SpeedVSReliability

Solution Approach 1:

The patent changes the fundamental parameter of degradation mechanism from abiotic (photo-oxidation) to biotic (enzymatic hydrolysis). By incorporating enzyme components that catalyze bond cleavage, the material degrades through biological pathways that maintain product safety and avoid the detrimental effects of photodegradation additives

Inventive Principle:

Principle #35Parameter changes

3Reliability

If natural materials are used to create biodegradable plastic, then biodegradability is improved, but cost effectiveness and physical properties deteriorate

Engineering Contradiction:

ImprovebiodegradabilityVSAvoidcost effectiveness

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent achieves multi-functionality by using peptide-enzyme-protein composition that simultaneously provides biodegradability, maintains compatibility with existing polyethylene processing infrastructure, and preserves mechanical properties. This allows the material to fulfill multiple functions (degradability, strength, cost-effectiveness) without requiring complete system overhaul

Inventive Principle:

Principle #6Universality (Multi-functionality)
