Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing packaging methods for grouped containers using heatshrink plastic films are environmentally harmful due to high energy consumption, single-use nature, and low recyclability, while alternative methods like strapping with composite materials face issues of non-recyclability and label damage.

Innovation Solution

A packaging device using a paper tape with folded longitudinal edges to form folds, which is biodegradable and recyclable, providing strength and integrity to the container batch.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If heatshrink plastic film is used to wrap containers, then batch integrity is maintained, but environmental harm increases due to high energy consumption and low recyclability

Engineering Contradiction:

Improvebatch integrityVSAvoidenvironmental harm

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The invention changes the material parameter from heatshrink plastic film to paper-based strapping material, which is biodegradable and recyclable, thereby reducing environmental harm while maintaining batch integrity through the folding mechanism that provides mechanical strength

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The invention extracts and eliminates the heating step from the packaging process by using pre-folded paper strapping material that provides structural integrity without requiring thermal energy input, thus removing the source of high energy consumption

Inventive Principle:

Principle #2Taking out (Extraction)

2Reliability

If self-adhesive tape is used to encircle the batch, then containers are held together, but recyclability decreases due to composite material composition

Engineering Contradiction:

Improvecontainer retentionVSAvoidrecyclability

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The invention uses homogeneous paper-based material for strapping instead of composite materials combining plastic and adhesive layers, making the entire strapping material recyclable and eliminating the difficulty of separating different material types

Inventive Principle:

Principle #33Homogeneity

Solution Approach 2:

The invention employs a simple paper strapping material that can be easily disposed of and replaced, accepting its short-living nature while maintaining environmental compatibility through biodegradability and recyclability

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Reliability

If self-adhesive tape is used to encircle the batch, then containers are held together, but label quality deteriorates due to adhesive contact

Engineering Contradiction:

Improvecontainer retentionVSAvoidlabel damage

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The invention extracts and removes the adhesive component from the strapping material, using mechanical folding and interlocking of paper edges instead of adhesive bonding, thereby eliminating the harmful effect of adhesive on container labels

Inventive Principle:

Principle #2Taking out (Extraction)

4Ease of manufacture

If paper tape with folded edges is used instead of plastic film, then recyclability improves, but structural strength may be compromised

Engineering Contradiction:

ImproverecyclabilityVSAvoidstructural strength

Core Design Contradiction:

Ease of manufactureVSStrength

Solution Approach 1:

The invention uses folded edges creating curved and interlocking structures in the paper strapping material, which distribute mechanical stresses and enhance structural strength without requiring additional materials or complex mechanisms

Inventive Principle:

Principle #14Spheroidality (Curvature)

AI summary

Provided is a packaging device for a compact batch of at least two grouped containers and methods of packaging containers in a batch using such a device. The device includes a strip, the strip having an inner face, an outer face and two longitudinal edges. The packaging device forms a belt surrounding the containers or a handle for handling the batch. At least one of the longitudinal edges is folded against one of the faces, of the strip so as to form at least one fold.
