Solution Overview

Problem

Existing separation devices for sausage portions filled with alginate or collagen often result in non-full closure at separation points, leading to undesirable optical properties and potential damage to the sausage ends during the separation process.

Innovation Solution

A separation device with a flexibly trained counter holder that applies a preload to the crimpelement, allowing for increased separation force without the need for cutting, ensuring complete closure of the alginate shell around the sausage portions by adjusting the bridge thickness and material selection to influence flexibility and separation force.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If rigid crimping elements are used for separating sausage portions, then the separation force is sufficient to separate portions, but the alginate casing is damaged and separation points are not completely sealed

Engineering Contradiction:
Improveseparation forceVSAvoidcasing damage
Core Design Contradiction:
ForceVSObject-affected harmful factors

Solution Approach 1:

The crimping element is designed with a flexible crimping section that can dynamically adapt its shape during the crimping process. The flexibility allows the crimping element to deform and conform to the casing shape, distributing the separation force more evenly and preventing localized damage while maintaining sufficient separating force.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the physical parameters of the crimping element by introducing flexibility through specific geometric designs (such as curved surfaces and rounded edges). This parameter change allows the same crimping element to achieve both sufficient separation force and gentle interaction with the casing, resolving the contradiction between force and damage prevention.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If cutting edges are added to crimping elements to improve separation, then portions can be separated more effectively, but the gentleness of the separation process is reduced and casing damage increases

Engineering Contradiction:
Improveseparation effectivenessVSAvoidcasing damage
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent removes the cutting edges from the crimping element design. By extracting this harmful feature, the separation process becomes gentler on the casing while still achieving effective portion separation through the flexible crimping action alone, eliminating the need for aggressive cutting mechanisms.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent converts the previously harmful effect of rigid crimping into a beneficial flexible crimping action. The flexibility that was potentially seen as a weakness is transformed into an advantage, allowing the crimping element to effectively separate portions while simultaneously protecting the casing from damage.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

3Object-affected harmful factors

If the crimping element is made more flexible to prevent casing damage, then the gentleness of separation improves, but the separation force may be insufficient

Engineering Contradiction:
Improvecasing damageVSAvoidseparation force
Core Design Contradiction:
Object-affected harmful factorsVSForce

Solution Approach 1:

The crimping element is designed with differentiated local properties: the crimping section has flexible curved surfaces for gentle interaction, while the legs and base section maintain sufficient rigidity to transmit and generate the necessary separation force. This local quality differentiation resolves the contradiction between flexibility and force generation.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent employs curved and rounded geometric surfaces on the crimping section, replacing sharp edges with smooth contours. This curvature design inherently provides flexibility while maintaining structural integrity, allowing the element to deform gently on the casing surface while still generating adequate separation force through its overall structure.

Inventive Principle:
Principle #14Spheroidality (Curvature)
