Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If raw data is transmitted from edge devices to centralized server for analysis, then model training and updates can be performed centrally, but bandwidth consumption and power usage increase significantly
Solution Approach 1:
The patent extracts only the essential features from raw data at the edge device level before transmission. Instead of sending complete raw datasets to the centralized server, edge devices perform local feature extraction and transmit only these condensed feature representations. This dramatically reduces the volume of transmitted data while preserving the information necessary for effective model training and updates.
2Ease of operation
If local models run solely on edge devices, then computational autonomy is improved, but model complexity and effectiveness are restricted by device capabilities
Solution Approach 1:
The patent segments the model management workflow into two distinct parts: feature extraction performed locally at edge devices, and model training/updates performed centrally on the server. This segmentation allows edge devices to maintain computational autonomy for feature extraction while leveraging centralized resources for complex model training, thereby resolving the contradiction between local autonomy and model effectiveness.
Solution Approach 2:
The patent introduces an intermediary feature representation layer between raw data and the centralized model training process. Edge devices transform raw data into feature vectors that serve as an intermediary representation, which can then be efficiently transmitted and used for centralized model training. This intermediary layer enables both local autonomy and access to centralized computational resources.
3Reliability
If hybrid approaches are used to balance local and centralized resources, then model performance can be improved, but system complexity increases
Solution Approach 1:
The patent clearly segments responsibilities between edge devices and centralized servers: edge devices handle feature extraction and local inference, while servers handle model training and updates. This explicit segmentation simplifies the hybrid architecture by defining clear boundaries between distributed and centralized operations, reducing system complexity while maintaining improved model performance.
