Solution Overview

Problem

Sealing stations face challenges in sealing packages where the product area is partially or completely above the sealing level, leading to exposure to disruptive gas flows, temperature fluctuations, and increased protective gas consumption, requiring complex and costly design modifications for different product geometries.

Innovation Solution

A sealing station with an adaptable receiving space that can be customized in shape and size using fitting inserts to accommodate various product areas, minimizing exposure to disruptive influences and allowing for efficient sealing of packages with product areas above the sealing level, including multi-layer packs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the upper part is designed with fixed receiving space for products above sealing level, then the sealing process can be performed, but the device complexity increases and adaptability to different product geometries decreases

Engineering Contradiction:
Improvesealing process reliabilityVSAvoidupper part design complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The upper part is designed with a movable receiving space that can be dynamically adjusted vertically. The receiving space can be positioned at different heights relative to the sealing level, allowing adaptation to various product geometries without increasing overall device complexity. This dynamic positioning capability maintains sealing reliability while reducing the need for complex fixed designs.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The upper part is divided into separate functional components: a movable receiving space and a sealing mechanism. This segmentation allows the receiving space to be independently adjusted for different product types while the sealing mechanism remains optimized for its function, reducing overall design complexity.

Inventive Principle:
Principle #1Segmentation

2Productivity

If the receiving space is enlarged to accommodate product areas above sealing level, then more products can be sealed, but gas flow disruptions and temperature fluctuations increase

Engineering Contradiction:
Improvesealing capacityVSAvoidgas flow disruptions and temperature fluctuations
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The receiving space can be dynamically positioned at optimal heights for different products, minimizing the volume exposed to disruptive gas flows and temperature fluctuations. By adjusting the vertical position rather than permanently enlarging the space, the system maintains sealing capacity while reducing harmful environmental factors.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The receiving space is designed with differentiated zones: areas close to the sealing level maintain controlled conditions for sealing, while areas farther away can accommodate product extensions. This local differentiation allows the space to serve multiple functions without uniformly exposing all areas to harmful factors.

Inventive Principle:
Principle #3Local quality

3Object-affected harmful factors

If protective elements are added to protect products from sealing tool influences, then product protection improves, but the device complexity and cost increase

Engineering Contradiction:
Improveproduct protection from sealing tool influencesVSAvoidprotective element complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

Instead of adding fixed protective elements, the system uses a movable receiving space that can be positioned to naturally protect products during the sealing process. The dynamic adjustment of the receiving space provides protective functionality without requiring additional complex protective components.

Inventive Principle:
Principle #15Dynamics
