Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual operations are used for meat grading, then workers can perform grading based on experience and observation, but labor costs increase and grading consistency deteriorates

Engineering Contradiction:
Improvegrading operationVSAvoidgrading consistency
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent replaces the manual mechanical grading system with an automated imaging and measurement system. Multi-dimensional imaging devices capture meat carcass data, and measurement systems automatically calculate grading parameters, eliminating reliance on human workers' subjective judgment and experience while ensuring consistent, objective grading results.

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

Solution Approach 2:

The patent creates digital copies of the meat carcass through multi-dimensional imaging. These digital models serve as replicas that can be measured and analyzed without physical contact, allowing the grading process to work with copied data rather than requiring direct manual measurement of the actual meat, thereby improving both efficiency and consistency.

Inventive Principle:
Principle #26Copying

2Adaptability or versatility

If manual grading is performed, then flexibility in judgment is maintained, but measurement precision and accuracy deteriorate

Engineering Contradiction:
Improvegrading judgment flexibilityVSAvoidgrading measurement accuracy
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent substitutes manual measurement tools and human judgment with automated imaging devices and computational algorithms. These systems provide precise, objective measurements of meat dimensions and characteristics, eliminating the imprecision inherent in manual methods while maintaining adaptability through programmable grading criteria.

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

Solution Approach 2:

The patent transitions from two-dimensional visual inspection to multi-dimensional imaging and measurement. By capturing depth, volume, and spatial relationships in addition to surface characteristics, the system achieves superior measurement precision while maintaining the flexibility to evaluate multiple grading parameters simultaneously.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Reliability

If highly skilled workers are employed for grading, then grading quality improves, but labor costs increase

Engineering Contradiction:
Improvegrading qualityVSAvoidlabor cost
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent replaces skilled human workers with automated measurement and imaging systems. These systems perform grading operations without requiring human expertise, thereby eliminating the need to pay premium wages for skilled labor while maintaining or improving grading quality through consistent, objective measurement.

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

Solution Approach 2:

The patent enables the meat grading system to perform its own measurement and evaluation functions autonomously. The imaging devices and measurement systems self-calibrate and self-evaluate according to programmed criteria, eliminating the need for human operators and associated labor costs while maintaining high grading quality.

Inventive Principle:
Principle #25Self-service
