Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If evaluation data and methods are manually constructed for specific domains, then evaluation accuracy for the language model is improved, but construction cost and time increase significantly

Engineering Contradiction:
Improveevaluation accuracyVSAvoidconstruction time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary conversion of multiple-choice questions into completion format questions in advance, creating evaluation data that can be directly used for language model assessment without requiring manual construction for each specific domain

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system copies and adapts existing multiple-choice questions from various domains, transforming them into completion format questions that can be used for evaluation, thereby avoiding the need to create entirely new evaluation data for each domain

Inventive Principle:
Principle #26Copying

2Adaptability or versatility

If multiple-choice questions are converted to completion format, then compatibility with language model evaluation is improved, but question format complexity increases

Engineering Contradiction:
Improveevaluation compatibilityVSAvoidquestion format complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system changes the format parameter of evaluation questions from multiple-choice structure to completion structure, making the questions compatible with language model evaluation while managing the complexity through systematic conversion processes

Inventive Principle:
Principle #35Parameter changes

3Reliability

If external knowledge utilization and preprocessing are integrated into the language model, then evaluation capability for specific domains is improved, but system complexity and cost increase

Engineering Contradiction:
Improveevaluation capabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system extracts the evaluation capability from the integrated system configuration and embeds it directly into the language model through completion format questions, eliminating the need for separate external knowledge utilization and preprocessing components

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system merges the evaluation function with the language model by using completion format questions that can be directly processed by the model, combining what were previously separate components (evaluation data, preprocessing, and model inference) into a unified standalone evaluation process

Inventive Principle:
Principle #5Merging (Combining)
