Solution Overview

Problem

Existing sausage portioning devices tend to tear casings, limit the number of twists, and are not easily cleanable, noisy, and produce sausages of fixed length.

Innovation Solution

A device with a rotating plate and clamps that pinch and twist continuous sausages using upper and lower rollers with concave and convex profiles to match the sausage shape, along with a lateral member and elastic return means to minimize casing tearing and allow for multiple twists, and a mechanism for easy cleaning and adjustable sausage length.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional twisting members with flat surfaces are used, then the sausage can be twisted, but the casing is torn and the number of twists is limited

Engineering Contradiction:
Improvecasing integrityVSAvoidtwisting capability
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The upper and lower twisting members are equipped with rollers having concave and convex curved surfaces that match the cylindrical shape of the sausage. This curvature allows the rollers to contact the sausage along its surface without creating stress concentration points, enabling multiple twists (more than 2.5 turns) without tearing the casing, thus resolving the contradiction between twisting capability and casing integrity.

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Strength

If sheep casings are used to prevent tearing, then casing strength is sufficient, but the number of twists is limited to 2.5 turns

Engineering Contradiction:
Improvecasing strengthVSAvoidnumber of twists
Core Design Contradiction:
StrengthVSProductivity

Solution Approach 1:

The invention changes the surface geometry parameter of the twisting members from flat to curved (concave/convex profiles). This parameter change allows the system to achieve more than 2.5 twists without increasing casing strength requirements, thereby increasing productivity while maintaining casing integrity regardless of casing type used.

Inventive Principle:
Principle #35Parameter changes

3Ease of manufacture

If the device structure is fixed, then it is simple to manufacture, but it cannot be dismantled for cleaning and produces noisy operation

Engineering Contradiction:
Improvedevice simplicityVSAvoidcleanability
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The device is divided into modular components including the plate, clamps, twisting members with rollers, and support structure. These segmented components can be easily detached from one another, allowing for simple dismantling and cleaning operations while maintaining overall device simplicity. The modular design enables maintenance without increasing manufacturing complexity.

Inventive Principle:
Principle #1Segmentation

4Device complexity

If the sausage length is fixed by the device design, then the device is simple, but it cannot produce sausages of varying lengths

Engineering Contradiction:
Improvedevice simplicityVSAvoidsausages length variability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The device incorporates adjustable elements that allow the operational parameters (such as the position of clamps or the rotation angle of the plate) to be dynamically changed during operation. This enables the production of sausages with varying lengths without requiring multiple fixed-device configurations, thus providing versatility while maintaining relative device simplicity.

Inventive Principle:
Principle #15Dynamics

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 device reduces casing tearing, increases the number of twists, and allows for the production of sausages with varying lengths and diameters while being quiet, easy to clean, and maintaining casing integrity.

Implementation Method 1

The lateral member is mounted to move relative to a support carrying it, in at least one direction extending transversely to a continuous sausage extending between the two clamps during a twisting operation, and in that the twisting means comprise elastic return means, called second elastic return means, of the lateral member towards a continuous sausage extending between the two clamps during a twisting operation.
