Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual assessment is used to classify trim products by fat percentage, then the process is simple and quick, but the accuracy and precision of fat percentage categorization deteriorates

Engineering Contradiction:
Improvefat percentage measurement accuracyVSAvoidprocessing system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces manual mechanical assessment with an automated imaging and analysis system. The system uses digital imaging to capture trim product images, processes these images through algorithms to determine fat percentage, and automatically categorizes the trim products. This substitution of manual inspection with automated optical and computational systems directly resolves the contradiction by providing high measurement precision without requiring complex manual evaluation procedures

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

Solution Approach 2:

The system enables self-service automation where the trim classification process performs itself without human intervention. The automated image processing and fat percentage calculation systems handle the entire classification workflow independently, from image capture to final categorization, eliminating the need for manual assessment while maintaining high accuracy

Inventive Principle:
Principle #25Self-service

2Manufacturing precision

If limited group sorting is used for trim products, then the sorting process is simple and fast, but the accuracy of fat percentage specification deteriorates

Engineering Contradiction:
Improvefat percentage specification accuracyVSAvoidsorting process efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The system dynamically adjusts classification granularity based on requirements. Rather than using fixed limited groups, the system can create dynamic classification thresholds and adjust the number of categories as needed, allowing both high precision specification and maintained productivity through automated rapid processing

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the parameter of classification resolution, allowing flexible adjustment between coarse and fine categorization. By dynamically modifying classification parameters based on product requirements, the system achieves high manufacturing precision when needed while maintaining productivity through automated processing

Inventive Principle:
Principle #35Parameter changes

3Measurement precision

If automated measurement systems are implemented, then the measurement precision of fat percentage improves, but the device complexity increases

Engineering Contradiction:
Improvefat percentage measurement accuracyVSAvoidmeasurement system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The imaging system serves multiple functions: capturing trim product images, determining fat percentage through image analysis, and providing data for classification decisions. This multi-functionality reduces the need for separate dedicated devices for each task, thereby improving measurement precision without proportionally increasing overall system complexity

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

4Stability of the object's composition

If feedback control is implemented for batch completion, then the consistency of fat percentage in batches improves, but the processing time and system complexity increase

Engineering Contradiction:
Improvebatch fat percentage consistencyVSAvoidbatch processing time
Core Design Contradiction:
Stability of the object's compositionVSLoss of time

Solution Approach 1:

The system implements feedback control by continuously monitoring measured fat percentages and using this information to adjust subsequent classification decisions. The controller receives measurement data and automatically adjusts batch composition to maintain target fat percentages, ensuring consistency while the automated nature of the feedback loop minimizes additional processing time

Inventive Principle:
Principle #23Feedback

AI summary

Method and system for processing of meat trim products, where trim products are supplied as a sequence of collections of trim (COTs), each collection of trim (COT) comprising a plurality of trim products, whereby - a fat/meat relationship for a collection of trim (COT) is measured, - a collection of trim (COT) is transferred to a selected station (24) by a separator (20), controlled by a controller (50, 51, 52), and whereby - a batch is completed at a selected station (24) on the basis of data for said fat/meat relationship, said batch comprising one or more collections of trim (COTs) and fulfilling a predetermined criterion regarding a total fat/meat relationship.
