Solution Overview

Problem

Existing food processing systems struggle to produce uniform large food portions with precise weight control, especially when dealing with varying product composition, as they require manual adjustments and cannot dynamically adjust cutting processes to achieve consistent portion weights.

Innovation Solution

A system with a transport device connected to the portioning section that transfers portions to a stacking device, incorporating a scale for weight measurement downstream of the portioning section, allowing for precise weight determination and automatic adjustments to ensure consistent portion weights.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a high-performance slicer is used to achieve high product throughput, then slicing speed is improved, but weight control precision deteriorates due to variations in slice weight and composition

Engineering Contradiction:
Improveslicing speedVSAvoidweight control precision
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The food product is divided into multiple slices that are then grouped into partial portions. The system segments the portion formation process into automated slicing and subsequent stacking of multiple partial portions to create complete food portions, allowing high-speed slicing while maintaining weight control through multiple measurement points

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The scale measures the weight of individual partial portions before they are stacked into complete food portions. This preliminary weight measurement allows the system to anticipate and adjust the total weight of the food portion before final assembly, ensuring precise weight control despite high slicing speeds

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If manual adjustments are made to compensate for weight fluctuations, then weight control precision is improved, but operation complexity increases

Engineering Contradiction:
Improveweight control precisionVSAvoidoperation complexity
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The scale provides continuous weight feedback for each partial portion and the complete food portion. The control unit processes this feedback information and automatically adjusts slicing parameters or stacking operations to maintain target weight, eliminating the need for manual adjustments and reducing operational complexity

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs self-adjustment based on scale measurements. The control unit automatically modifies slicing depth, blade position, or portion composition to compensate for weight variations without requiring manual intervention, making the system self-regulating and easier to operate

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If separate weighing steps are introduced to ensure weight consistency, then weight control precision is improved, but processing time increases

Engineering Contradiction:
Improveweight control precisionVSAvoidprocessing time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The weighing function is merged into the main production flow by integrating the scale within the slicing and stacking system. Weight measurement occurs continuously during the portion formation process rather than as a separate post-processing step, eliminating additional processing time while maintaining precision

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The scale operates continuously throughout the portion formation process, measuring each partial portion as it is created and the final food portion before discharge. This continuous measurement eliminates interruptions and separate weighing steps, maintaining high productivity while ensuring weight consistency

Inventive Principle:
Principle #20Continuity of useful action
