Solution Overview

Problem

Existing pressing devices for meat products, particularly those used in processing lines, face challenges in minimizing size and complexity while ensuring efficient movement of pressing means, often resulting in increased costs and reduced efficiency due to the need for complex drive systems to achieve necessary travel distances.

Innovation Solution

The use of a rotatable eccentric drive that allows the pressing means to move over 90°, preferably up to 180°, enabling a larger travel distance with a smaller eccentricity, thus reducing the required torque and eliminating the need for inefficient translations between rotary and linear movements, resulting in a more compact and cost-effective design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If complex deflections are used to redirect linear movement transversely to the direction of travel, then the pressing device width can be minimized, but the drive design becomes complex and expensive

Engineering Contradiction:
Improvepressing device widthVSAvoiddrive design complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

Instead of using complex deflections to redirect linear movement, the invention inverts the approach by using a rotatable pressing means that converts rotary movement directly into pressing action. The pressing means rotates about a horizontal axis, with its pressing surface oriented perpendicular to the direction of travel, eliminating the need for transverse redirection mechanisms and simplifying the overall drive design.

Inventive Principle:
Principle #13The other way round (Inversion)

2Area of stationary object

If complex deflections are used to redirect linear movement, then the pressing device width can be minimized, but drive efficiency is reduced

Engineering Contradiction:
Improvepressing device widthVSAvoiddrive efficiency
Core Design Contradiction:
Area of stationary objectVSLoss of energy

Solution Approach 1:

The invention eliminates energy losses associated with complex deflection mechanisms by inverting the approach: the pressing means itself rotates to perform the pressing action. This direct rotary-to-compression conversion removes intermediate transmission stages, thereby maintaining drive efficiency while achieving a compact width.

Inventive Principle:
Principle #13The other way round (Inversion)

3Area of stationary object

If the pressing means is moved by a drive with complex deflections, then the device width is reduced, but the construction cost increases

Engineering Contradiction:
Improvepressing device widthVSAvoidconstruction cost
Core Design Contradiction:
Area of stationary objectVSEase of manufacture

Solution Approach 1:

By inverting the pressing mechanism to use direct rotation, the invention eliminates costly complex deflection components. The pressing means simply rotates about a horizontal axis, requiring only basic rotational support structures rather than expensive multi-stage transmission systems, thereby reducing construction costs.

Inventive Principle:
Principle #13The other way round (Inversion)

4Length of moving object

If a large eccentricity is used to achieve necessary travel distance, then the pressing means can move sufficiently, but the required torque increases

Engineering Contradiction:
Improvepressing means travel distanceVSAvoidrequired torque
Core Design Contradiction:
Length of moving objectVSForce

Solution Approach 1:

Instead of using a large eccentricity in a reciprocating mechanism that would require high torque, the invention inverts by using direct rotation of the pressing means. The pressing surface rotates about a horizontal axis, converting rotary motion directly into compression force, thereby achieving sufficient travel distance with significantly reduced torque requirements.

Inventive Principle:
Principle #13The other way round (Inversion)

AI summary

A pressing device for pressing meat products, in particular frozen and/or partially frozen meat products, preferably fresh meat products and/or bacon, comprises a pressing chamber. The pressing chamber includes a counter element and a pressing element movable by means of a drive, wherein the pressing element can be moved from a starting position towards the counter element to a final position for compressing the product, and wherein the drive is configured to drive at least one eccentric rotatable about a pivot axis for moving the pressing element from the starting position to the final position, wherein the pressing element can be moved from the starting position to the final position by a rotation of more than 90 degrees of the eccentric.
