Solution Overview

Problem

The consumer packaging industry faces environmental and social challenges due to the procurement, production, transport, and disposal of traditional packaging, and there is a growing demand for sustainable packaging solutions that are cost-effective and meet performance criteria.

Innovation Solution

A flexible packaging system comprising a plastic component formed into thin sheets or films with an embedded fiber matrix and an inflatable scaffolding component that can be internally or externally associated, providing rigidity when inflated with air, gas, or foam, allowing for compact storage and transportation in an uninflated state and transformation into a rigid or semi-rigid container.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional rigid packaging is used, then structural strength and stability are maintained, but material usage and transportation costs increase

Engineering Contradiction:
Improvestructural strengthVSAvoidmaterial usage
Core Design Contradiction:
StrengthVSLoss of substance

Solution Approach 1:

The packaging system transitions from a static rigid structure to a dynamic flexible structure that can change its mechanical properties. The flexible container remains soft during storage and transportation but becomes rigid when inflated with gas or foam, providing structural strength only when needed for product containment and protection.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The mechanical properties of the packaging are changed by altering the physical state of the container. By inflating the flexible container with gas or foam, the material parameters change from a collapsed soft state to an expanded rigid state, achieving the required structural strength without using traditional rigid materials.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If traditional rigid packaging is used, then product protection is ensured, but transportation efficiency and storage space decrease

Engineering Contradiction:
Improveproduct protectionVSAvoidtransportation efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The packaging system dynamically adjusts its form factor. During transportation and storage, the container remains deflated and flexible, maximizing space utilization and transportation efficiency. When needed for product protection, the container is inflated to provide the necessary rigid structure and reliability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The flexible container can be collapsed and nested within itself or with other containers during storage and transportation, similar to nested dolls. This nesting capability dramatically improves transportation efficiency and storage space while maintaining the ability to provide full product protection when inflated.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Loss of substance

If flexible packaging without scaffolding is used, then material reduction is achieved, but structural support and rigidity are insufficient

Engineering Contradiction:
Improvematerial reductionVSAvoidstructural support
Core Design Contradiction:
Loss of substanceVSStrength

Solution Approach 1:

The flexible container incorporates a pneumatic or foam-based scaffolding system that provides structural support through gas pressure or foam expansion. This internal pressurization system creates the necessary rigidity and structural support while using minimal material, as the gas or foam acts as a lightweight internal framework.

Inventive Principle:
Principle #29Pneumatics and hydraulics

Solution Approach 2:

The packaging system combines flexible plastic or polymer materials with gas or foam components to create a composite structure. This composite approach provides both the flexibility and material reduction benefits of thin-walled containers while the embedded gas or foam scaffolding delivers the required structural support and rigidity.

Inventive Principle:
Principle #40Composite materials

4Object-affected harmful factors

If sustainable packaging materials are used, then environmental impact is reduced, but manufacturing complexity and cost increase

Engineering Contradiction:
Improveenvironmental impactVSAvoidmanufacturing complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The packaging uses thin flexible shells made from sustainable materials such as biodegradable plastics or recycled polymers. These thin films reduce material usage and environmental impact while the inflatable scaffolding system provides the necessary structural support, keeping the overall manufacturing process relatively simple.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The manufacturing process utilizes parameter changes, particularly phase transitions of gas or foam, to create the structural support. This approach allows sustainable flexible materials to be combined with a simple inflation process, avoiding complex manufacturing steps while achieving both environmental sustainability and structural integrity.

Inventive Principle:
Principle #35Parameter changes
