Solution Overview

Problem

Existing packaging solutions for sliced cold meat, such as rigid pans and multi-sachet systems, occupy excessive space on shelves and in display cases, making it difficult for consumers to quickly view products and pose challenges in disposal, while also not being aesthetically appealing.

Innovation Solution

A space-saving bag made of transparent plastic sheets joined along the edges, folded and secured with a sticker, featuring hooking means for hanging, optimized for display and environmentally friendly disposal, with options for cylindrical or conical rolling and compartmentalization for extended freshness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If rigid pans or multi-sachet systems are used for packaging sliced cold meat, then product protection and freshness are ensured, but excessive space is occupied on shelves and in display cases

Engineering Contradiction:
Improveproduct protectionVSAvoidshelf space
Core Design Contradiction:
ReliabilityVSVolume of stationary object

Solution Approach 1:

The packaging is divided into two separate sheets (outer sheet and inner sheet) that are joined together, allowing the package to be folded compactly while maintaining product protection. The outer sheet provides structural integrity and hanging capability, while the inner sheet directly contacts and protects the meat product.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent uses flexible plastic sheets instead of rigid pans, allowing the packaging to be folded into a compact form that occupies minimal shelf space. The flexible material maintains product protection while enabling space-efficient storage and display.

Inventive Principle:
Principle #30Flexible shells and thin films

2Reliability

If existing packaging solutions are used, then product containment is achieved, but consumer visibility and quick glancing at products is hindered

Engineering Contradiction:
Improveproduct containmentVSAvoidproduct visibility
Core Design Contradiction:
ReliabilityVSIllumination intensity

Solution Approach 1:

The transparent plastic sheets allow light to pass through, enabling consumers to see the meat product clearly while the sheets maintain product containment. The transparency of the material resolves the contradiction between containment and visibility.

Inventive Principle:
Principle #30Flexible shells and thin films

3Reliability

If multi-sachet systems with handles are used, then product protection is provided, but device complexity increases and aesthetic appeal is reduced

Engineering Contradiction:
Improveproduct protectionVSAvoidpackaging structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The outer sheet and inner sheet are joined together along their edges to form an integrated packaging structure, eliminating the need for separate sachets and handles. This merged design simplifies the overall structure while maintaining product protection and adding hanging capability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The outer sheet serves multiple functions: it provides structural support, enables hanging through the formed hook, and acts as a carrier for the inner sheet. This multi-functionality reduces the need for additional components like separate handles.

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

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The solution provides a compact and visually appealing packaging that optimizes shelf space, ensures product freshness, and facilitates easy disposal, enhancing consumer appeal and environmental sustainability.

Implementation Method 1

The two sheets 12 are joined for example through heat sealing carried out at least along the perimetric edge 13 to keep the sliced meat 11 in the necessary conditions of conservation

Methodology Applied
Scientific EffectHeat sealing: Welding

Implementation Method 2

the sticker 14, having an eyelet 15 as hooking means, obtained through punching of a portion 16 of the sticker itself, is glued to the two opposite edges 13b at the fold of the bag

Methodology Applied
Scientific EffectAdhesive bonding: Adhesive
