Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If spectral analysis is used to analyze seed roots and leaves, then measurement precision is improved, but calculation intensity increases and device complexity worsens

Engineering Contradiction:
Improveseed structure identification accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the seed structure analysis into distinct morphological components (radicle, hypocotyl, cotyledons, plumule, etc.) and develops specific spectral models for each structure. This segmentation allows the complex analysis to be broken down into manageable parts, improving measurement precision for each structure while making the overall system more tractable

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary action by creating predetermined spectral models for various seed structures before actual analysis. These pre-established models (including reflectance, transmittance, and fluorescence characteristics) are stored and readily available for rapid comparison during seed analysis, reducing real-time calculation intensity while maintaining high measurement precision

Inventive Principle:
Principle #10Preliminary action

2Productivity

If spectral analysis focuses only on hypocotyl and radicle, then calculation intensity is reduced, but adaptability to different seed types worsens

Engineering Contradiction:
Improveanalysis efficiencyVSAvoidapplicability to different seed types
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent creates a universal spectral analysis system that can identify multiple morphological structures across different seed types. The system uses a comprehensive library of spectral models covering radicles, hypocotyls, cotyledons, plumules, and other structures, allowing it to adapt to various seed types (dicots, monocots, gymnosperms) without requiring separate analysis protocols for each type

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

Solution Approach 2:

The patent employs parameter changes by adjusting spectral analysis parameters (wavelength ranges, threshold values, model selection) based on the specific seed type being analyzed. The system can switch between different spectral models and adjust analysis parameters to optimize both productivity and adaptability for different seed categories

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If traditional image analysis with thresholding is used, then ease of operation is improved, but measurement precision and classification accuracy worsen

Engineering Contradiction:
Improvesoftware operation simplicityVSAvoidseed structure classification accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent replaces traditional mechanical thresholding operations with spectral analysis methods. Instead of using simple intensity thresholding to distinguish seed structures, the system uses spectral reflectance, transmittance, and fluorescence characteristics combined with predictive models. This substitution maintains ease of operation through automated software while dramatically improving measurement precision and classification accuracy through physics-based spectral differentiation

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

AI summary

This disclosure relates to a method and system that models a seed structure and uses a spectral analysis to identify which morphological seed structures are existent in the seed/seedling. Additionally, this disclosure relates to a method and system that applies multi- spectral analysis using predetermined models of a seed/seedling to identify which morphological structures are existent in the seed/seedling. The information about the existence or non-existence of structures of the seed/seedling is used to classify the seed as having a specific characteristic, for later commercial use or sale. The seed market determines which specific characteristic the method will use to classify the seed/seedling. The individual seed classification may help determine associated seed lot germination values.
