Solution Overview

Problem

Conventional plastic straws are non-biodegradable, contribute to pollution, and lack nutritional or organoleptic functionality, failing to provide additional benefits during drink consumption.

Innovation Solution

Development of an edible and biodegradable straw made from a pastillage-based composition, which remains rigid in cold drinks for up to an hour without altering the drink's taste or aroma, using ingredients like gelatin, icing sugar, and glycerine, and a manufacturing process involving extrusion and controlled drying to ensure durability and stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If plastic straws are used, then mechanical strength and rigidity are maintained, but biodegradability is lost and pollution increases

Engineering Contradiction:
Improvemechanical strengthVSAvoidpollution
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent changes the material composition parameters by using pastillage (a mixture of water, sugar, gelatin, and stabilizing agents) instead of conventional plastic materials. This parameter change transforms the straw from non-biodegradable plastic to an edible, biodegradable material that maintains sufficient mechanical strength for its intended use while eliminating pollution concerns.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent employs composite materials by combining multiple ingredients (water, sugar, gelatin, stabilizing agents) to create pastillage-based straws. This composite approach allows the material to achieve the necessary mechanical properties for straw functionality while maintaining biodegradability and edibility, resolving the contradiction between strength and environmental harm.

Inventive Principle:
Principle #40Composite materials

2Object-affected harmful factors

If edible materials are used for straws, then biodegradability is improved, but mechanical strength and rigidity deteriorate

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

Solution Approach 1:

The patent optimizes the parameter composition of pastillage by carefully selecting ratios of water, sugar, gelatin, and stabilizing agents. This parameter optimization enables the edible material to achieve sufficient mechanical strength and rigidity for straw functionality while maintaining complete biodegradability and edibility.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The use of composite pastillage materials combining multiple functional ingredients allows the straw to achieve enhanced mechanical properties through synergistic interactions between components, while remaining fully biodegradable and edible, thus resolving the strength-biodegradability contradiction.

Inventive Principle:
Principle #40Composite materials

3Ease of operation

If the straw remains rigid in cold drinks, then functionality is maintained, but dissolution time increases

Engineering Contradiction:
ImprovefunctionalityVSAvoiddissolution time
Core Design Contradiction:
Ease of operationVSDuration of action of moving object

Solution Approach 1:

The patent adjusts the physical and chemical parameters of the pastillage composition to control dissolution rate. By optimizing the ratio of ingredients and their molecular structure, the straw maintains rigidity and functionality during normal use in cold drinks while ensuring complete dissolution within an acceptable time frame, resolving the contradiction between functionality and dissolution speed.

Inventive Principle:
Principle #35Parameter changes
