Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional packaging materials, such as polyethylene, are not compostable and pose disposal challenges, necessitating the development of recyclable and compostable alternatives that provide protection during shipping.

Innovation Solution

A packaging wrap primarily composed of starch or a combination of starch and other compostable materials, which can be rolled for convenience and includes perforations or pads surrounded by films for additional protection, ensuring compostability and recyclability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional polyethylene packaging material is used, then the packaging provides good protection and is inexpensive, but it is not compostable and creates disposal problems

Engineering Contradiction:

Improveprotection capabilityVSAvoiddisposal problem

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent changes the material composition parameter from conventional polyethylene to starch-based compostable materials, maintaining protective functionality while eliminating disposal problems through compostability

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The packaging wrap uses composite structure with starch-based materials combined with compostable films and adhesives, creating a multi-layer system that provides both protection and environmental compatibility

Inventive Principle:

Principle #40Composite materials

2Object-generated harmful factors

If starch-based compostable material is used, then the packaging becomes compostable and recyclable, but the material flexibility and formability may be reduced

Engineering Contradiction:

ImprovecompostabilityVSAvoidformability

Core Design Contradiction:

Object-generated harmful factorsVSEase of manufacture

Solution Approach 1:

The patent optimizes the starch content parameter (at least 85% by weight) and processes the material to achieve the right balance between compostability and flexibility for rolling and forming

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The packaging wrap is designed as a flexible strip or film that can be rolled around items, with controlled depth and density to maintain flexibility while using starch-based compostable material

Inventive Principle:

Principle #30Flexible shells and thin films

3Reliability

If the packaging wrap is made thick and dense for better protection, then protection capability improves, but the ability to roll and store conveniently is reduced

Engineering Contradiction:

Improveprotection capabilityVSAvoidrollability

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent controls the depth (between 1/8 inches and 2.5 inches) and density parameters to achieve optimal balance between protection capability and flexibility for rolling

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The packaging wrap is designed with dynamic flexibility allowing it to be rolled into compact forms (radius between 1 inch and 20 inches) for storage while maintaining protective properties when deployed

Inventive Principle:

Principle #15Dynamics
