Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If natural language processing systems process electronic medical records in various formats, then the system can handle diverse data sources, but the data structure incompatibility leads to inaccurate prediction results

Engineering Contradiction:
Improvedata format compatibilityVSAvoidprediction accuracy
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent transforms unstructured electronic medical record data into structured vector representations, changing the parameter format from diverse text formats to standardized numerical vectors. This allows the system to maintain adaptability across different data sources while ensuring prediction accuracy through consistent vectorized input to machine learning models

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent introduces natural language processing models as an intermediary layer between diverse electronic medical record formats and the prediction system. This intermediary automatically transforms various data formats into unified vector representations, resolving structure incompatibility without requiring manual data curation while maintaining prediction accuracy

Inventive Principle:
Principle #24Intermediary (Mediator)

2Stability of the object's composition

If manual data curation is performed to standardize medical records, then data structure compatibility improves, but the time and resources required increase significantly

Engineering Contradiction:
Improvedata structure consistencyVSAvoiddata preparation time
Core Design Contradiction:
Stability of the object's compositionVSLoss of time

Solution Approach 1:

The patent implements self-service data standardization through automated natural language processing models that independently transform electronic medical records into consistent vector formats without human intervention. The system automatically handles data structure consistency while eliminating the time-consuming manual curation process

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical process of manual data curation with automated natural language processing and machine learning models. This substitution maintains data structure consistency through algorithmic transformation while dramatically reducing the time and human resources required for data preparation

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

3Device complexity

If temporal information is not captured in medical records, then data processing is simpler, but prediction accuracy for health states deteriorates

Engineering Contradiction:
Improvedata processing complexityVSAvoidhealth state prediction accuracy
Core Design Contradiction:

Solution Approach 1:

The patent applies preliminary action by embedding temporal information into the vector representations during the initial data transformation phase. The natural language processing models incorporate time-related features into the vectorized data before it reaches the prediction system, ensuring that temporal context is preserved without increasing processing complexity later in the pipeline

Inventive Principle:
Principle #10Preliminary action
