Solution Overview

Problem

Current packaging methods for containers using plastic heatshrink films are energy-intensive, generate significant waste, and are not environmentally friendly, while alternative solutions like cardboard supports and adhesive tapes either use excessive materials or compromise batch solidity.

Innovation Solution

A semi-extensible paper strip is used to hold containers together, providing elasticity and resistance to ensure batch cohesion and integrity without the environmental drawbacks of plastic or excessive material usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If plastic heatshrink film is used to wrap containers, then batch cohesion and container retention are improved, but environmental harm and energy consumption increase

Engineering Contradiction:

Improvebatch cohesionVSAvoidenvironmental harm

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the material parameter from plastic heatshrink film to paper band, fundamentally altering the chemical composition and environmental properties while maintaining the mechanical function of batch retention

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The paper band is positioned as a disposable, biodegradable alternative to plastic film, accepting single-use functionality while eliminating long-term environmental persistence and enabling composting or pulping disposal methods

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

2Strength

If plastic heatshrink film wrapping is used, then batch solidity is improved, but energy consumption increases

Engineering Contradiction:

Improvebatch solidityVSAvoidenergy consumption

Core Design Contradiction:

StrengthVSUse of energy by moving object

Solution Approach 1:

The patent extracts the heating step from the packaging process by eliminating heatshrink film, retaining only the essential function of batch retention without the energy-intensive thermal contraction phase

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The paper band accepts a disposable role that eliminates the need for energy-intensive heating processes, using simple mechanical wrapping and adhesive bonding instead

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Reliability

If cardboard support is used to hold containers, then batch retention is improved, but material usage and weight increase

Engineering Contradiction:

Improvebatch retentionVSAvoidmaterial usage

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent uses a thin paper band that wraps around and conforms to the container batch shape, providing retention through circumferential binding rather than rigid structural support, thereby minimizing material quantity

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The paper band is applied as a thin, flexible element that segments the batch into manageable units through circumferential wrapping, providing adequate retention without the bulk and weight of cardboard structures

Inventive Principle:

Principle #1Segmentation

4Reliability

If self-adhesive tape is used to encircle the batch, then batch cohesion is improved, but recyclability decreases

Engineering Contradiction:

Improvebatch cohesionVSAvoidrecyclability

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent changes the material composition parameter from composite adhesive tape to pure paper band, eliminating the mixture of plastics and adhesives that complicate recycling and enabling straightforward pulping or composting processes

Inventive Principle:

Principle #35Parameter changes
