Solution Overview

Problem

Existing packaging machines are limited in their ability to efficiently package articles in various carton formats while minimizing material usage and ensuring strength for transporting heavy loads, and they lack the capability to automatically form multi-packs with minimal waste.

Innovation Solution

A packaging machine with multiple conveyor systems and transfer devices that allows for the flexible packaging of articles in cartons or plastic film, enabling the formation of multi-packs by merging article paths and using a tertiary packaging apparatus for further grouping and wrapping in plastic material.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If articles are packaged in paperboard cartons using the carton packaging apparatus, then the packaging strength for holding and transporting large weights is improved, but the material usage and wastage increase

Engineering Contradiction:
Improvepackaging strengthVSAvoidmaterial wastage
Core Design Contradiction:
StrengthVSLoss of substance

Solution Approach 1:

The packaging machine dynamically switches between two packaging paths: one for paperboard cartons and another for plastic film wrapping. This allows the system to adapt to different packaging requirements, using cartons when strength is needed and plastic film when material minimization is prioritized, thereby resolving the contradiction between packaging strength and material wastage

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention changes the packaging parameter by offering two distinct packaging materials (paperboard cartons and plastic film) with different properties. The system can select the appropriate material based on the specific requirements of each packaging task, allowing optimization between strength and material usage for each individual package

Inventive Principle:
Principle #35Parameter changes

2Ease of manufacture

If the packaging machine uses a single fixed packaging format, then the manufacturing process is simplified, but the adaptability to various carton formats is reduced

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidcarton format adaptability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The packaging machine is designed with multi-functionality by incorporating two independent packaging paths: one for paperboard cartons and another for plastic film wrapping. This universal design allows the same machine to handle multiple packaging formats and requirements, achieving both manufacturing simplicity through standardized processes and adaptability through path selection

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The packaging system is segmented into two independent paths, each optimized for a specific packaging type. This segmentation allows each path to be independently controlled and optimized, maintaining manufacturing simplicity for each individual path while providing overall system adaptability through the ability to choose between paths

Inventive Principle:
Principle #1Segmentation

3Productivity

If articles are wrapped in plastic film before carton packaging, then the packaging efficiency and speed are improved, but the device complexity increases

Engineering Contradiction:
Improvepackaging efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system dynamically configures the packaging process by allowing articles to either receive plastic film wrapping before carton packaging or proceed directly to carton packaging. This dynamic configuration enables the system to optimize for speed when plastic wrapping is applied, while managing complexity through automated path selection and integration

Inventive Principle:
Principle #15Dynamics
