Solution Overview

Problem

Existing food processing devices lack flexibility and the ability to weigh sliced portions, and conventional conveyors are complex and inflexible, limiting their functionality.

Innovation Solution

A food processing device with a discontinuous conveyor using a contactless drive system, such as magnetic levitation, allows for flexible movement of conveying carriers without a fixed path, integrated with a lifting device and a scale to measure portion weights, enabling precise control over portion shape and weight.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conveyor belt is used to transport sliced food products, then continuous transport is achieved, but the system becomes complex and inflexible

Engineering Contradiction:
Improveconveyor flexibilityVSAvoidconveyor complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The conveyor system is segmented into multiple independent conveying carriers (12, 13) that can be individually controlled and positioned. Each carrier operates independently rather than as part of a continuous belt, allowing flexible routing and positioning while reducing overall system complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The conveying carriers are made dynamically movable within a conveying area without being bound to a fixed conveying path. The contactless drive system enables real-time repositioning and dynamic control of each carrier's position and speed, providing adaptability while maintaining simple individual carrier designs.

Inventive Principle:
Principle #15Dynamics

2Measurement precision

If conventional conveyors are used, then transport function is provided, but the ability to weigh portions and control drop height is lost

Engineering Contradiction:
Improveportion weighing capabilityVSAvoidfunctionality
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The conveying carriers are designed as multi-functional units that combine transport, weighing, and positioning functions. Each carrier can transport slices, be weighed by integrated or external scales to determine portion weight, and have its drop height independently controlled, providing versatile functionality in a single integrated system.

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

Solution Approach 2:

The system incorporates feedback through scales that measure the weight of conveying carriers with slices, and through control devices that use this information to regulate the positioning and movement of carriers. This closed-loop feedback enables precise portion control and consistent drop heights by adjusting carrier positions based on measured weights.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If a fixed conveying path is used, then simple conveyor design is achieved, but flexibility in portion shape and positioning is reduced

Engineering Contradiction:
Improveportion shape controlVSAvoidconveyor path complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The conveying carriers operate without being bound to a fixed conveying path, allowing dynamic repositioning within the conveying area. This enables the system to adapt to different portion shapes and positioning requirements by programmatically controlling carrier trajectories rather than relying on fixed mechanical paths.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The contactless drive system replaces traditional mechanical conveyor mechanisms with a non-contact actuation method. This substitution eliminates the need for complex mechanical guiding structures and fixed paths, allowing carriers to be moved and positioned flexibly through electromagnetic or other contactless forces while reducing mechanical complexity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

The invention relates to a food-processing device for slicing food articles (2) into slices (6), the slices (6) preferably jointly forming a portion, more particularly for slicing pieces of meat or pieces of cheese. The food-processing device according to the invention comprises a cutting device (1) for cutting the slices (6) off the food articles (2) and a conveyor (AS, 12-18) for receiving, after a cutting process, the slices (6) that have been cut off. The conveyor (AS, 12-18) is preferably disposed in the fall line of the slices (6) so that the slices (6) that have been cut off fall from the cutting device (1) onto the conveyor (AS, 12-18). According to the invention, the conveyor (AS, 12-18) is a discontinuous conveyor which, in contrast to a conveyor belt, discontinuously conveys the deposited slices (6). The invention also relates to a corresponding operating method.
