Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional preclinical screening methods are used to discover antimicrobial compounds, then comprehensive experimental validation can be performed, but the time and cost of the discovery process becomes excessively high

Engineering Contradiction:
Improveexperimental validation of antimicrobial compoundsVSAvoidtime for compound discovery
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by performing in silico screening and machine learning predictions before actual wet lab experiments. The system pre-identifies promising compounds from millions of candidates using computational models, then validates only the top predictions experimentally. This preliminary computational filtering dramatically reduces the number of compounds requiring expensive and time-consuming preclinical screening while maintaining high reliability of discovery.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses in silico models as computational copies of physical screening systems. Machine learning models are trained on existing antimicrobial data to create virtual screening environments that replicate the predictive power of experimental screening without the associated time and cost. These digital twins allow rapid evaluation of compound efficacy before physical validation.

Solution Approach 1:

The patent implements feedback loops where machine learning models are continuously trained and refined using results from experimental validations. Predicted compounds are tested in wet lab experiments, and the actual outcomes feed back into the training data, improving model accuracy over time. This iterative feedback mechanism reduces false predictions while maintaining high discovery productivity.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent performs preliminary validation of machine learning predictions through targeted wet lab experiments on selected top candidates. This preliminary experimental check filters out false positives before full-scale development, ensuring that only reliably predicted compounds proceed to further development stages.

Inventive Principle:
