Solution Overview

Problem

The handling of security paper sheets for document production, such as banknotes, involves high manual effort, risk of damage, and challenges in flatness and stackability, along with significant packaging waste, necessitating improved mechanical and climatic protection during storage and transport.

Innovation Solution

A packaging system utilizing a stack carrier with intermediate layers and a hood-shaped jacket made of corrugated cardboard, featuring a surface finish that reduces friction and includes overhangs for easy extraction, providing mechanical and climatic protection while optimizing space and reducing packaging material.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If security paper sheets are stacked on pallets in single-ream packages, then mechanical and climatic protection is provided, but manual effort and risk of damage increase

Engineering Contradiction:

Improvemechanical and climatic protectionVSAvoidmanual effort

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The packaging is divided into modular components: a reusable stacking carrier, disposable intermediate layers with extraction projections, and a hood-shaped mantle. This segmentation allows the carrier to be reused while disposing of protective layers after single use, reducing manual handling effort and damage risk.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Intermediate layers are introduced between the stacking carrier and printed material stacks, and between stacks. These intermediary layers provide mechanical protection, prevent direct contact, and enable easier handling while reducing damage to the valuable security paper sheets.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If intermediate layers are added between stacks, then mechanical protection is improved, but packaging material and weight increase

Engineering Contradiction:

Improvemechanical protectionVSAvoidpackaging material

Core Design Contradiction:

ReliabilityVSLoss of substance

Solution Approach 1:

The intermediate layers are designed as disposable protective elements that are discarded after single use. This eliminates the need for cleaning and reuse maintenance, reducing overall packaging material consumption while providing adequate mechanical protection during the critical storage and transport phase.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

Thin-film intermediate layers are used instead of bulky protective structures. These thin films provide sufficient mechanical protection and climatic barrier while minimizing added weight and packaging material consumption.

Inventive Principle:

Principle #30Flexible shells and thin films

3Reliability

If a hood-shaped mantle is used to enclose the stack, then mechanical protection is improved, but ease of unpacking deteriorates

Engineering Contradiction:

Improvemechanical protectionVSAvoidease of unpacking

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The hood-shaped mantle is designed with extraction projections that allow selective removal of intermediate layers without disturbing the stacked printed materials. This extraction mechanism enables easy unpacking while maintaining the protective enclosure during transport.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The protective enclosure is segmented into the stacking carrier, intermediate layers with extraction projections, and hood-shaped mantle. This segmentation allows the mantle to be opened or removed independently without affecting the stability of the stacked materials, facilitating easy unpacking.

Inventive Principle:

Principle #1Segmentation

4Stability of the object's composition

If multiple intermediate layers are used, then flatness and stackability are improved, but device complexity increases

Engineering Contradiction:

Improveflatness and stackabilityVSAvoidpackaging structure

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

Flexible thin-film intermediate layers are used that can conform to the stacking carrier and printed materials while maintaining flatness. These flexible films simplify the overall structure compared to rigid support structures, reducing device complexity while ensuring proper flatness and stackability.

Inventive Principle:

Principle #30Flexible shells and thin films
