Solution Overview

Problem

Cloud backup methods for mobile electronic devices are inefficient due to the large volume of data being backed up, leading to frame freezing, high power consumption, and network congestion, resulting in prolonged backup times.

Innovation Solution

The method involves dividing the data to be backed up into multiple data sets and distributing these sets across the first device and one or more auxiliary devices, which then upload the data sets to a cloud platform simultaneously, utilizing high-speed transmission methods.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If data backup is performed using a single mobile electronic device, then the backup process can be completed, but the backup time is prolonged and backup efficiency is low

Engineering Contradiction:

Improvebackup efficiencyVSAvoidbackup time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent divides the backup task into multiple segments by splitting data into multiple data sets that are distributed across multiple devices (first device and auxiliary devices). Each device independently uploads its allocated data set to the cloud platform, enabling parallel processing and significantly reducing overall backup time.

Inventive Principle:

Principle #1Segmentation

2Reliability

If large volume data is backed up using a single device, then all data can be uploaded, but network congestion and power consumption increase

Engineering Contradiction:

Improvedata backup completenessVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent segments the large volume of data into multiple smaller data sets that are distributed across multiple auxiliary devices. This division reduces the data transmission burden on each individual device and the network, thereby reducing power consumption and avoiding network congestion while ensuring complete data backup.

Inventive Principle:

Principle #1Segmentation

3Loss of energy

If data backup is performed during idle time of the electronic device, then power consumption and traffic consumption are reduced, but backup efficiency remains low

Engineering Contradiction:

Improvepower consumptionVSAvoidbackup efficiency

Core Design Contradiction:

Loss of energyVSProductivity

Solution Approach 1:

The patent merges the backup operations of multiple devices (first device and multiple auxiliary devices) into a coordinated parallel backup system. By distributing data sets across multiple devices that can operate simultaneously during their respective idle times, the system achieves both energy efficiency and high backup efficiency through parallel processing.

Inventive Principle:

Principle #5Merging (Combining)
