Solution Overview

Problem

Current cloud-based analytics face issues such as privacy invasion, network dependency, high bandwidth consumption, and slow response times due to the need for data transmission to a distant cloud, while edge computing struggles with processing large data and varies in performance across different edges, limiting its ability to handle complex computations and consistent model allocation.

Innovation Solution

A cloud-edge distributed operation method where the cloud creates multiple models and allocates them to edges based on their capabilities, allowing edges to perform lightweight operations and the cloud to handle in-depth learning and analytics, with data preprocessing and separation techniques to protect privacy and optimize bandwidth usage, and task modularization for distributed processing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If data is transmitted to cloud for analytics, then professional and advanced analytics can be performed, but network bandwidth is consumed and response time increases

Engineering Contradiction:
Improveanalytics depthVSAvoidbandwidth consumption
Core Design Contradiction:
Measurement precisionVSLoss of energy

Solution Approach 1:

The patent segments analytics tasks into two categories: simple field-level analytics performed at edge devices and complex professional analytics performed in the cloud. This segmentation allows critical analytics to be performed locally without consuming network bandwidth, while still enabling deep analysis for tasks that require cloud resources.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements preliminary data processing and filtering at the edge before transmission to the cloud. By performing initial analytics and preprocessing locally, the system reduces the volume of data that needs to be transmitted to the cloud, thereby reducing bandwidth consumption while maintaining analytical depth for transmitted data.

Inventive Principle:
Principle #10Preliminary action

2Measurement precision

If data is transmitted to cloud for analytics, then advanced analysis can be performed, but privacy invasion may occur

Engineering Contradiction:
Improveanalytics depthVSAvoidprivacy invasion
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent segments data processing between edge and cloud, keeping sensitive data processing at the edge where it remains local. Only anonymized or aggregated results are transmitted to the cloud, maintaining analytical depth while protecting privacy by preventing exposure of raw sensitive data.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent extracts and removes sensitive information from data before cloud transmission. By separating sensitive attributes from analytical data and processing them locally at the edge, the system enables cloud analytics on non-sensitive data while protecting privacy through extraction of harmful elements.

Inventive Principle:
Principle #2Taking out (Extraction)

3Speed

If analytics are performed at edge, then response speed improves, but processing capability is limited compared to cloud

Engineering Contradiction:
Improveresponse speedVSAvoidprocessing capability
Core Design Contradiction:
SpeedVSProductivity

Solution Approach 1:

The patent segments analytics workloads by complexity, assigning time-critical simple analytics to edge devices for fast response and computationally intensive complex analytics to the cloud for high processing capability. This segmentation allows the system to achieve both fast response speeds and high processing capabilities for different task types.

Inventive Principle:
Principle #1Segmentation

4Reliability

If edge computing is used, then network dependency is reduced, but difficulty in allocating models consistently across different edges increases

Engineering Contradiction:
Improvenetwork independenceVSAvoidmodel allocation complexity
Core Design Contradiction:

Solution Approach 1:

The patent changes the parameter of model allocation from manual configuration to automated selection based on edge device characteristics. By dynamically adjusting model allocation decisions according to device capabilities, data types, and performance requirements, the system achieves consistent and optimal model distribution across heterogeneous edge devices without manual intervention.

Inventive Principle:

AI summary

Disclosed herein are a method and system for distributed operation between a cloud and an edge in an Internet of Things (IoT) computing environment including the edge and the cloud, the edge being connected to things to collect data from the things and transmit a control signal to the things, and the cloud being configured to receive data from the edge, process the data, and transmit a result of the processing to the edge. Traffic and load of the cloud for data processing are adaptively allotted to the edge depending on the situation such that the data is processed through cooperation between the edge and the cloud, and optimum processing results are provided. The distributed operation of the edge and cloud is performed so as to shorten the response time, to make the best of processing power, to be network-independent, and to protect data as much as possible.
