Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumers following dietary restrictions, such as Kosher or Halal, face challenges in determining the authenticity of meat products due to the inability to visually verify proper slaughter methods and animal types, leading to uncertainty and hesitation in consumption.
Innovation Solution
A device utilizing spectroscopy and machine learning algorithms, specifically support vector machine (SVM) classifiers, to classify unknown meat samples into Kosher, Halal, or non-compliant categories by analyzing spectroscopic measurements, aggregating multiple groups into meta-groups to improve classification accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If visual inspection methods are used to verify meat authenticity, then the process is simple and quick, but the accuracy and reliability of identification are insufficient
Solution Approach 1:
The patent replaces visual inspection (mechanical/optical system) with spectroscopic analysis (electromagnetic radiation interaction). The spectrometer measures absorption, emission, or reflection spectra to identify meat type and authenticity, providing objective chemical composition data that cannot be obtained through visual inspection alone.
Solution Approach 2:
The patent introduces spectroscopic measurements and machine learning algorithms as intermediaries between the meat sample and the identification result. The spectrometer captures spectral data, which is then processed through classification models to determine meat authenticity, serving as an intermediary analysis layer that transforms physical samples into verified identification outcomes.
2Reliability
If spectroscopic analysis with machine learning is implemented, then the classification accuracy improves, but the device and process complexity increases
Solution Approach 1:
The patent performs preliminary actions by pre-training machine learning classification models with extensive spectral data before deployment. The classification models are prepared in advance with knowledge of different meat types, enabling rapid and reliable classification during actual use without requiring complex real-time computation or manual analysis.
Solution Approach 2:
The system performs self-service through automated spectral analysis and machine learning classification. The spectrometer and classification model work together autonomously to identify meat types and detect adulteration without requiring expert intervention, reducing operational complexity while maintaining high reliability.
3Reliability
If multiple classification models are used to aggregate meta-groups, then the robustness of identification improves, but the computational complexity increases
Solution Approach 1:
The patent segments the classification task into multiple specialized classification models, each trained on specific meta-groups of meat types. Instead of using one comprehensive model, the system divides the problem into smaller, more manageable classification tasks that can be executed more efficiently and with higher accuracy for each specific category.
Solution Approach 2:
The patent merges results from multiple classification models through aggregation of meta-groups. The system combines the outputs of individual classification models to produce a final robust identification, leveraging the strengths of each specialized model while maintaining computational efficiency through structured aggregation.
