Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional MoE architectures are used to process specific tasks based on large-volume data, then computational efficiency is improved, but VRAM requirements increase significantly

Engineering Contradiction:
Improvecomputational efficiencyVSAvoidVRAM requirements
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

The patent segments the MoE model into multiple independently trained specialized models (experts) that can be selectively activated. Instead of loading all expert models into memory simultaneously, the system divides them into manageable groups and activates only the necessary subset for each specific task, reducing peak VRAM requirements while maintaining computational efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic model loading and unloading mechanisms that adapt to the specific computational task at hand. The system dynamically selects which expert models to activate based on the input data characteristics and task requirements, loading only the necessary models into VRAM and unloading others, thereby optimizing memory usage while preserving computational performance.

Inventive Principle:
Principle #15Dynamics

2Reliability

If conventional MoE architectures activate multiple expert models, then task processing capability is improved, but resource utilization efficiency deteriorates

Engineering Contradiction:
Improvetask processing capabilityVSAvoidresource utilization efficiency
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent applies local quality by assigning different levels of activation or computation intensity to different expert models based on their specific strengths and the characteristics of the input data. Instead of uniformly activating all expert models, the system selectively engages specific experts with appropriate computation resources matched to their specialized functions, optimizing resource utilization while maintaining task processing capability.

Inventive Principle:
Principle #3Local quality

3Device complexity

If one-size-fits-all AI models are used to provide services, then model simplicity is maintained, but adaptability to specific contexts deteriorates

Engineering Contradiction:
Improvemodel simplicityVSAvoidcontext adaptability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent creates a universal MoE framework that can handle multiple different tasks and contexts through a single system architecture. The gateway model serves as a universal interface that routes various types of input data to appropriate specialized expert models, enabling the system to adapt to diverse contexts while maintaining a relatively simple overall structure through modular design.

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

4Reliability

If conventional MoE architectures are fine-tuned, then model performance is improved, but training time and computational cost increase

Engineering Contradiction:
Improvemodel performanceVSAvoidfine-tuning time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-training multiple specialized expert models independently on different data subsets or for different tasks before combining them into the MoE architecture. This preliminary independent training allows each expert to develop specialized capabilities efficiently, and the gateway model learns routing strategies in advance, reducing the need for extensive joint fine-tuning time while achieving high overall model performance.

Inventive Principle:
Principle #10Preliminary action
