Solution Overview

Problem

Existing packaging machines for flat articles, particularly ceramic tiles, face limitations in production rate and durability due to the use of two-layer packaging material, leading to potential damage and frequent reel replacements, which result in machine downtime and operational inefficiencies.

Innovation Solution

A packaging method and apparatus that utilizes a feeding system to efficiently manage reels of packaging material, including a die-cutting machine to form blanks, and a packaging apparatus that wraps articles with pairs of blanks to protect edges and corners, enhancing production speed and reducing material waste.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of substance

If packaging material with only two layers of cardboard is used to reduce material quantity and storage volume, then the amount of packaging material used is reduced and storage volume is decreased, but the durability and resistance to damage from sharp edges are compromised

Engineering Contradiction:
Improveamount of packaging materialVSAvoiddurability of packaging material
Core Design Contradiction:
Loss of substanceVSReliability

Solution Approach 1:

The patent applies composite materials by combining a first cardboard layer with a foam layer having elastomeric properties. This composite structure provides both the reduced material quantity benefit and the enhanced durability needed to resist damage from sharp edges during high-speed packaging operations.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent changes the physical parameters of the packaging material by incorporating a foam layer with specific elastomeric properties. This parameter change enables the material to be more resistant to tearing and damage while maintaining flexibility for winding and high-speed operation.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If conveying speed is increased to improve production rate, then productivity is improved, but the risk of damaging the packaging material increases due to greater stresses during wrapping

Engineering Contradiction:
Improveproduction rateVSAvoidintegrity of packaging material
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent applies beforehand cushioning by incorporating a foam layer with elastomeric properties into the packaging material structure. This cushioning effect is built into the material itself, allowing it to absorb stresses during high-speed conveying and wrapping operations without tearing or damaging the material.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The composite structure of cardboard combined with elastomeric foam provides both the structural integrity needed for high-speed operation and the flexibility required for successful wrapping around articles.

Inventive Principle:
Principle #40Composite materials

3Volume of stationary object

If reels of packaging material are used instead of sheets to reduce storage volume, then storage space is optimized, but frequent reel replacements are required leading to machine downtime

Engineering Contradiction:
Improvestorage volumeVSAvoidmachine downtime
Core Design Contradiction:
Volume of stationary objectVSLoss of time

Solution Approach 1:

The patent enables continuity of useful action by designing a reel feeding system that maintains continuous operation during reel transitions. The automated reel replacement process minimizes interruptions, allowing the packaging operation to continue with minimal downtime and maintaining production efficiency.

Inventive Principle:
Principle #20Continuity of useful action

4Ease of operation

If automated reel feeding system is implemented to reduce manual intervention, then ease of operation is improved and machine downtime is reduced, but device complexity increases

Engineering Contradiction:
Improveautomation of reel handlingVSAvoidcomplexity of feeding system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent applies self-service by implementing an automated reel feeding system that performs reel replacement and material feeding without manual intervention. The system serves itself by automatically detecting when reels need replacement and executing the changeover process, thereby improving ease of operation despite the increased device complexity.

Inventive Principle:
Principle #25Self-service
