Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If training data is generated by adding manual analysis results to images, then the training data can be created, but it requires a lot of man-hours to generate the training data

Engineering Contradiction:
Improveamount of training dataVSAvoidman-hours to generate training data
Core Design Contradiction:
Quantity of substanceVSLoss of time

Solution Approach 1:

The system uses automated inference models to generate training data labels independently without manual analysis. The determination device automatically selects appropriate inference results from multiple models to create training data, eliminating the need for human analysts to add labels to images.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical process of manual analysis with an automated determination device that uses multiple inference models. This substitution transforms the labor-intensive manual labeling process into an automated computational process that rapidly generates training data.

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

2Productivity

If a training data generation unit with low accuracy is used, then training data can be generated quickly, but the quality of the generated training data deteriorates

Engineering Contradiction:
Improvespeed of training data generationVSAvoidquality of training data
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The system segments the training data generation process into multiple independent inference models, each specializing in different aspects of analysis. By dividing the work among multiple models and then determining the best results, the system achieves both high speed and high quality training data generation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The determination device dynamically selects inference results based on changing parameters such as confidence levels, model performance metrics, and data characteristics. This adaptive selection process ensures that only high-quality inference results are used to generate training data, maintaining quality while preserving speed.

Inventive Principle:
Principle #35Parameter changes

3Manufacturing precision

If multiple inference models are used to generate training data, then the quality of the training data set can be improved, but the device complexity increases

Engineering Contradiction:
Improvequality of training data setVSAvoidcomplexity of inference model system
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent merges multiple inference models into a unified determination device that coordinates their outputs. By combining the strengths of multiple models and using a centralized determination mechanism to select the best results, the system achieves high training data quality while managing complexity through integration.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The determination device acts as an intermediary between multiple inference models and the training data generation process. It receives outputs from various models, evaluates their quality, and selects appropriate results for training data creation, thereby managing the complexity of multiple models without compromising output quality.

Inventive Principle:
Principle #24Intermediary (Mediator)
