Solution Overview

Problem

Existing grayscale-upgrade methods fail to ensure all users can use updated operating systems and applications normally after an upgrade, as they are not suitable for all terminal devices, leading to incomplete testing and intended effects not being achieved.

Innovation Solution

Selecting social groups and users with higher activity levels for grayscale-upgrading, based on their network usage and transaction frequency, to achieve better testing results and improve upgrade efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If grayscale-upgrade is performed on all terminal devices simultaneously, then upgrade speed is improved, but testing completeness deteriorates because some devices are not suitable for grayscale-upgrade

Engineering Contradiction:
Improveupgrade speedVSAvoidtesting completeness
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent segments the terminal devices into different groups based on their activity levels (high, medium, low). By dividing the upgrade process into segments targeting different user groups sequentially, the system achieves both comprehensive testing coverage and maintained upgrade efficiency. High-active users are upgraded first for rapid testing, followed by other user groups, ensuring all devices are eventually upgraded while maintaining testing completeness.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If grayscale-upgrade notification is sent to each terminal device individually, then device-specific control is improved, but notification efficiency deteriorates

Engineering Contradiction:
Improvedevice-specific controlVSAvoidnotification efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent merges the notification process by sending a single grayscale-upgrade notification to a social group (which represents multiple terminal devices) simultaneously, rather than sending individual notifications to each device. This combining approach maintains device-specific control because the notification can still target specific devices within the group while improving notification efficiency through batch processing.

Inventive Principle:
Principle #5Merging (Combining)

3Quantity of substance

If grayscale-upgrade is performed on inactive users, then coverage is improved, but testing effect deteriorates due to low network usage and transaction frequency

Engineering Contradiction:
Improveupgrade coverageVSAvoidtesting effect
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The patent performs preliminary classification of terminal devices based on user activity levels before initiating the grayscale-upgrade process. By pre-identifying high-active users and prioritizing them for early upgrade testing, the system ensures that devices most likely to provide meaningful test results are upgraded first. This preliminary sorting action ensures both comprehensive eventual coverage and high-quality testing effects.

Inventive Principle:
Principle #10Preliminary action

AI summary

A method for grayscale-upgrading includes determining a target social group to be grayscale-upgraded, determining a target user account to be grayscale-upgraded in the target social group, and grayscale-upgrading an application or device corresponding to the target user account.
