Solution Overview

Problem

Conventional plastic products, including bioplastics, are not easily recyclable or compostable, leading to significant environmental issues such as microplastic pollution and ecological damage, necessitating a sustainable and biodegradable alternative for everyday items and packaging.

Innovation Solution

Development of biodegradable and compostable granules made from natural, plant-based components like vegetable starch, thickening agents, and optional additives such as glycerin and vegetable fibers, which can be processed into various products using injection molding or extrusion, offering a fully recyclable and compostable solution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If conventional plastic granules are used to manufacture products, then the products have good mechanical properties and durability, but the products are not biodegradable and cause environmental pollution

Engineering Contradiction:
Improveenvironmental pollutionVSAvoidproduct durability
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent changes the chemical composition parameters of the granulate by using plant starch (40-60%), thickening agents (40-60%), and optional natural additives (0-20%), replacing conventional plastic materials. This parameter change enables the granulate to be biodegradable while maintaining usable product properties through controlled composition ratios.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite material system combining multiple plant-based components: starch as the base material, thickening agents for structural properties, and optional additives like fibers, waxes, and natural rubber for enhanced functionality. This composite approach allows the material to achieve both biodegradability and adequate mechanical performance.

Inventive Principle:
Principle #40Composite materials

2Object-affected harmful factors

If bioplastics like PLA are used to manufacture products, then the products are partially biodegradable, but they cannot be proven to be completely degradable and are banned in single-use products

Engineering Contradiction:
ImprovebiodegradabilityVSAvoidcomposting certification
Core Design Contradiction:
Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The patent optimizes the composition parameters to achieve complete biodegradability, with starch (40-60%) and thickening agents (40-60%) as the core biodegradable components. The controlled parameter ranges ensure the material meets composting standards while maintaining versatility for various product applications.

Inventive Principle:
Principle #35Parameter changes

3Object-affected harmful factors

If conventional plastic granules are produced and processed, then the products are durable and functional, but the granules escape into the environment and form microplastics in water bodies

Engineering Contradiction:
Improvemicroplastic pollutionVSAvoidprocessing simplicity
Core Design Contradiction:
Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The patent converts the potential harm of granulate escape into a benefit by using inherently biodegradable plant-based materials. Instead of trying to prevent escape, the material is designed to safely decompose in the environment, turning the risk of pollution into an environmental benefit through natural decomposition.

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

Solution Approach 2:

The patent changes the material composition parameters to plant-based starch and thickening agents that are biodegradable, maintaining ease of manufacture through similar processing methods while eliminating microplastic pollution risks.

Inventive Principle:
Principle #35Parameter changes

4Object-affected harmful factors

If natural plant-based components are used to manufacture granules, then the granules are biodegradable and compostable, but the mechanical properties and stability may be reduced

Engineering Contradiction:
ImprovecompostabilityVSAvoidgranulate strength
Core Design Contradiction:
Object-affected harmful factorsVSStrength

Solution Approach 1:

The patent creates a composite material system where plant starch (40-60%) provides biodegradability, thickening agents (40-60%) contribute structural strength and stability, and optional natural additives (0-20%) such as fibers, waxes, and natural rubber enhance mechanical properties. This composite structure achieves both compostability and adequate strength.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent optimizes the composition parameters within specific ranges: starch 40-60%, thickening agents 40-60%, and optional additives 0-20%. These parameter controls balance biodegradability with mechanical strength, ensuring the granulate is both compostable and sufficiently strong for manufacturing.

Inventive Principle:
Principle #35Parameter changes
