Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single machine learning model is used to learn multiple characteristic machining elements simultaneously, then the system structure is simple, but the number of parameters increases and computational load becomes large

Engineering Contradiction:
Improvesystem structureVSAvoidcomputational load
Core Design Contradiction:
Device complexityVSPower

Solution Approach 1:

The patent divides the machine learning system into multiple independent learning models, with each model dedicated to learning a specific characteristic machining element. This segmentation reduces the number of parameters per model and decreases computational load compared to a single comprehensive model, while maintaining the ability to learn multiple elements through parallel model execution.

Inventive Principle:
Principle #1Segmentation

2Device complexity

If a single machine learning model is used to learn multiple characteristic machining elements, then the model structure is simple, but the learning period of time increases

Engineering Contradiction:
Improvemodel structureVSAvoidlearning period of time
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

By segmenting the learning task into multiple specialized models, each model can converge faster on its specific characteristic element. The overall learning time is reduced because each model learns its dedicated element more efficiently rather than a single model attempting to learn all elements simultaneously with a larger parameter space.

Inventive Principle:
Principle #1Segmentation

3Device complexity

If a single machine learning model is used to learn multiple characteristic machining elements, then the system is simple, but memory requirements increase

Engineering Contradiction:
Improvesystem structureVSAvoidmemory
Core Design Contradiction:
Device complexityVSQuantity of substance

Solution Approach 1:

The patent segments the memory requirements by allocating separate memory spaces for each independent learning model. This approach reduces the peak memory usage compared to a single large model, as each smaller model only requires memory for its own parameters and computation, rather than all parameters being loaded simultaneously into one large model.

Inventive Principle:
Principle #1Segmentation

4Productivity

If multiple machine learning parts are used to learn different machining elements respectively, then learning efficiency is improved, but the system becomes more complex

Engineering Contradiction:
Improvelearning efficiencyVSAvoidsystem structure
Core Design Contradiction:

Solution Approach 1:

The patent implements segmentation by creating multiple independent learning models, each optimized for a specific characteristic machining element. This segmentation improves learning efficiency by allowing parallel processing and specialized learning for each element type, while the modular structure manages complexity through clear separation of functions.

Inventive Principle:
Principle #1Segmentation
