Solution Overview

Problem

Existing devices and methods for embossing sealing films in packaging face issues such as adverse effects on adhesion between packaging containers and lids, and the need for frequent replacement of embossing tools due to limited functionality and high maintenance costs.

Innovation Solution

A device with a basic embossing element and interchangeable embossing elements that produce haptically perceptible information, allowing for multifunctional embossing that enhances separation and information provision, featuring a system with a receiving area for multiple interchangeable elements and a matrix design for varied embossing patterns.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If an embossing is provided on the sealing film to prevent sticking during stacking and removal, then separation of shaped pieces is improved, but adhesion between the packaging container and the shaped piece deteriorates

Engineering Contradiction:
Improveseparation of shaped piecesVSAvoidadhesion
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The embossing is localized to specific regions of the sealing film that do not interfere with the sealing edge. The embossed pattern is positioned in areas separate from the heat-sealing lacquer application zone, allowing non-stick properties in the embossed areas while maintaining full adhesion capability in the sealing regions.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The sealing film is functionally segmented into different zones: embossed regions for separation and non-embossed sealing regions for adhesion. This spatial segmentation allows each region to perform its specific function without compromising the other.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the embossing tool is replaced to change the embossing pattern, then adaptability is improved, but device complexity and time expenditure increase

Engineering Contradiction:
Improveembossing pattern variabilityVSAvoidembossing tool replacement
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A single embossing tool design serves multiple functions by accommodating different embossing patterns through interchangeable elements. The standardized receiving area and fixing means create a universal interface that can hold various embossing elements, eliminating the need for multiple specialized tools.

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

Solution Approach 2:

The embossing tool incorporates movable and interchangeable elements that can be easily swapped during operation. The fixing means allow for quick release and replacement of embossing elements, transforming a static tool into a dynamic, adaptable system.

Inventive Principle:
Principle #15Dynamics
