VSEngineering Contradiction Analysis

1Manufacturing precision

If multiple inference models are used to generate training data, then the quality of training data improves, but the device complexity increases

Engineering Contradiction:
Improvequality of training dataVSAvoidcomplexity of generation device
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The generation device is divided into multiple independent inference models (first inference model, second inference model, etc.), each responsible for generating training data from different perspectives or using different algorithms. This segmentation allows each model to specialize in specific aspects of data generation, improving overall data quality while maintaining manageable complexity through modular architecture

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The generation device is designed as a multi-functional system that can perform multiple inference operations simultaneously using different inference models. Each model serves a specific function in the training data generation process, and the device can selectively apply different models based on the requirements, making the system universally applicable to various data generation scenarios

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Manufacturing precision

If manual analysis is used to generate training data, then the quality of training data improves, but the productivity decreases

Engineering Contradiction:
Improvequality of training dataVSAvoidspeed of training data generation
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The system employs inference models that automatically analyze and generate training data without requiring manual intervention. The models self-service by processing input data, generating predictions, and producing training data autonomously, thereby maintaining high data quality through algorithmic precision while achieving high productivity through automated operation

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Manual mechanical analysis operations are replaced with automated inference models that use computational algorithms to perform data analysis. This substitution eliminates the need for human analysts while maintaining or improving data quality through consistent, repeatable computational processes that can operate at high speeds

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

Solution Approach 1:

Multiple inference models are merged into a single integrated generation device that operates cooperatively. The models combine their individual strengths to produce training data with higher accuracy than any single model could achieve alone, while the unified device structure manages complexity through coordinated operation of the merged components

Inventive Principle:
Principle #5Merging (Combining)
