Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual permission setting is performed on each device, then permission control precision is maintained, but operation efficiency deteriorates and time consumption increases
Solution Approach 1:
The system enables automatic permission synchronization where the first electronic device autonomously detects permission changes and transmits them to the second electronic device without requiring manual intervention on each device. The permission management system automatically retrieves updated permission information from the cloud server and applies it, eliminating the need for users to manually repeat permission setting operations on multiple devices.
Solution Approach 2:
The system implements a feedback mechanism where permission changes on one device are detected, transmitted to the cloud server, and then propagated to other devices. The system continuously monitors permission states and automatically updates synchronized devices, creating a closed-loop feedback system that maintains permission consistency across all devices without manual intervention.
2Ease of operation
If automatic permission synchronization is implemented, then operation efficiency is improved, but system complexity increases
Solution Approach 1:
The cloud server acts as an intermediary between multiple electronic devices, centralizing the permission synchronization logic. Instead of devices directly communicating with each other, all permission changes are routed through the cloud server which manages the synchronization process. This intermediary approach simplifies the overall system architecture by providing a single point of coordination for permission management across devices.
Solution Approach 2:
The permission management system is designed with universal functionality that can operate across different types of electronic devices. The same permission synchronization mechanism works for various device types (smartphones, tablets, laptops) by utilizing common cloud server protocols, reducing the need for device-specific implementation details and simplifying the overall system design.
3Stability of the object's composition
If permission changes are synchronized to all devices, then permission consistency is improved, but information loss risk increases when security levels differ
Solution Approach 1:
The system applies local quality by considering the security level of each individual device when synchronizing permissions. Instead of uniformly applying all permission changes to all devices, the system evaluates each device's security characteristics and selectively applies permission updates accordingly. This allows the system to maintain permission consistency where security levels are compatible while preventing potential security issues on devices with lower security levels.

AI summary
This application provides an application permission synchronization method and a related device. The method is applied to a first electronic device, and the method includes: in response to a first user operation, changing permission granting information of a first application on the first electronic device, where the permission granting information is used to describe a permission granted to the first application to invoke at least one of a software function or a hardware function of the first electronic device; and if a security level of the first electronic device is higher than a security level of a second electronic device, synchronizing the change of the permission granting information of the first application on the first electronic device to the second electronic device based on permission synchronization configuration information of the first application on the first electronic device and the second electronic device.
