Solution Overview

Problem

Manual cutting of meat products into special portions is inefficient, resulting in low output and high wastage due to the inability to adjust cutting to varying contours and irregular surfaces, leading to slow processing and significant material loss.

Innovation Solution

A method and arrangement for portion cutting involving two cutting stages, where the first stage cuts items into strips, and the second stage cuts these strips into pieces of predetermined weight and dimensions using multiple cutting units with adjustable feeding directions, allowing for precise and efficient cutting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If manual cutting is used by experienced workers, then cutting precision and portion quality are maintained, but productivity is low and meat wastage is high (17-20%)

Engineering Contradiction:
Improveportion cutting precisionVSAvoidcutting speed
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The cutting process is divided into multiple sequential cutting units, each performing a specific cutting operation. The meat product passes through several cutting stages with different cutting directions and angles, allowing complex portion shapes to be achieved systematically while maintaining precision and increasing throughput capacity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cutting apparatus incorporates adjustable cutting units that can be positioned and angled dynamically to match the contours of the meat product. The cutting units can be adjusted in position and orientation to optimize cutting precision for different portion requirements while maintaining high cutting speed.

Inventive Principle:
Principle #15Dynamics

2Manufacturing precision

If manual cutting is used by experienced workers, then portion quality is maintained, but meat wastage is high (17-20%)

Engineering Contradiction:
Improveportion qualityVSAvoidmeat wastage
Core Design Contradiction:
Manufacturing precisionVSLoss of substance

Solution Approach 1:

The cutting units are designed with adjustable positions and angles that can be dynamically configured to match the exact contours and dimensions of the meat product. This dynamic adjustability allows the cutting apparatus to follow the natural shape of the meat, minimizing unnecessary removal of material while maintaining high portion quality standards.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent replaces manual mechanical cutting with an automated cutting system that uses computer-controlled mechanisms. This substitution eliminates the variability and inefficiency of manual cutting, allowing precise control over cutting paths to minimize wastage while maintaining consistent portion quality.

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

3Productivity

If automated cutting with stationary parallel knives is used, then cutting speed is increased, but adaptability to varying contours and irregular surfaces is lost

Engineering Contradiction:
Improvecutting speedVSAvoidcontour adaptation
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The cutting units are designed with multiple degrees of freedom, allowing them to be positioned and angled dynamically to match the contours of the meat product. Each cutting unit can be independently adjusted in position and orientation, enabling the system to adapt to varying shapes and sizes while maintaining high cutting speeds through automated operation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The cutting apparatus is designed as a universal system that can handle various types of meat products with different contours and dimensions. The adjustable cutting units can be reconfigured for different cutting patterns and portion requirements, providing versatility while maintaining automated high-speed operation.

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

4Manufacturing precision

If manual cutting training is provided to workers, then cutting skill is improved, but training time is extended and productivity remains low

Engineering Contradiction:
Improvecutting skillVSAvoidtraining time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent replaces the need for skilled manual cutting with an automated cutting system that incorporates computer control and programmable cutting paths. This substitution eliminates the requirement for extensive worker training while maintaining or improving cutting precision through automated control systems that can be programmed with optimal cutting parameters.

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