Solution Overview

Problem

There is a need to reduce the use of plastic stretch film in packaging while maintaining effective load unitization, and paper wrapping material is a recyclable eco-friendly alternative.

Innovation Solution

A system and method for forming a sleeve of paper wrapping material around a load using a conveyor system and a wrapping device that includes a roll-support assembly, first and second roller assemblies, a gripper assembly, an adhesive-applicator assembly, a cutter assembly, and a controller to control the application and formation of the sleeve.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If plastic stretch film is used for wrapping loads, then load unitization is effective, but environmental friendliness and recyclability deteriorate

Engineering Contradiction:
Improveload unitizationVSAvoidenvironmental friendliness
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the material parameter from plastic stretch film to paper wrapping material, transforming the wrapping material's composition to achieve recyclability and environmental friendliness while maintaining unitization effectiveness through controlled application parameters

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system uses paper wrapping material as a composite alternative to plastic film, combining recyclability with functional performance through the wrapping system's design that ensures proper application and load securation

Inventive Principle:
Principle #40Composite materials

2Object-affected harmful factors

If paper wrapping material is used instead of plastic stretch film, then environmental friendliness is improved, but the complexity of the wrapping system increases

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

Solution Approach 1:

The wrapping system is designed with multi-functional components including roller assemblies that can apply material, adhesive applicators for securing, and cutters for finishing, allowing a single system to handle the complete paper wrapping process without requiring separate specialized equipment

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

Solution Approach 2:

The system introduces an adhesive-applicator assembly as an intermediary component that facilitates the bonding of paper wrapping material to the load, enabling effective unitization without requiring complex mechanical fastening systems

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If paper wrapping material is applied using rollers and adhesive, then effective load securation is achieved, but the time required for wrapping increases

Engineering Contradiction:
Improveload securationVSAvoidwrapping time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The wrapping system operates continuously with the paper wrapping material being fed through rollers and applied to the load in an uninterrupted sequence, with the adhesive applicator working simultaneously as the material is positioned, eliminating idle time between steps

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The adhesive is applied to the paper wrapping material in advance before the material is fully positioned on the load, allowing the bonding process to begin while positioning is still in progress, thereby overlapping operations and reducing total wrapping time

Inventive Principle:
Principle #10Preliminary action
