Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If generic text mining methods are used to extract bacterial associations from biomedical literature, then the extraction process is simple and fast, but the accuracy is low and false positives are high

Engineering Contradiction:
Improveaccuracy of bacterial association identificationVSAvoidcomplexity of text mining system
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent changes the parameters of text mining by transitioning from generic methods to domain-specific methods tailored for bacterial association extraction. This includes using specialized lexical resources, domain-specific classification schemas, and customized feature extraction parameters that are optimized for microbiological text, thereby improving accuracy while managing complexity through targeted optimization.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent introduces intermediary components such as domain-specific lexical resources, classification schemas, and feature extraction modules that act as mediators between the raw text and the final association identification. These intermediaries process and structure the information in a way that enhances accuracy while organizing the complexity into manageable stages.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If correlation-based methods are used to predict bacterial associations from microbiome data, then candidate associations are generated quickly, but false positives increase

Engineering Contradiction:
Improvespeed of association predictionVSAvoidreliability of bacterial association predictions
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent applies preliminary action by using text mining to pre-validate candidate associations before they are considered reliable. The system extracts experimental evidence from biomedical literature to confirm or refute correlation-based predictions, thereby filtering out false positives while maintaining the speed advantage of correlation-based methods for initial candidate generation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback mechanisms where the results from text mining validation are fed back into the association prediction process. This feedback loop allows the system to adjust and refine its predictions based on experimental evidence, improving reliability while maintaining productivity through iterative optimization.

Inventive Principle:
Principle #23Feedback

3Measurement precision

If manual curation of bacterial associations is performed, then high accuracy is achieved, but the process is time-consuming and labor-intensive

Engineering Contradiction:
Improveaccuracy of bacterial association extractionVSAvoidtime required for association validation
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies self-service by designing a system that automatically performs text mining, classification, and validation tasks that would otherwise require manual curation. The system uses automated algorithms to extract and validate bacterial associations from biomedical literature, significantly reducing the time and labor required while maintaining high accuracy through domain-specific processing.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical process of manual curation with automated computational methods. Machine learning algorithms, natural language processing techniques, and automated classification systems substitute for human experts in extracting and validating bacterial associations, thereby reducing time loss while preserving accuracy through sophisticated automated analysis.

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