Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual permission setting is performed on each device, then permission control accuracy is improved, but operation complexity and time consumption increase

Engineering Contradiction:
Improvepermission control accuracyVSAvoidtime consumption
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system enables automatic permission synchronization where the first electronic device autonomously determines whether to synchronize permission changes based on security level comparisons and configuration information, eliminating the need for manual intervention on each device while maintaining accurate permission control

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements a feedback mechanism where permission change information is automatically transmitted from the first electronic device to the second electronic device based on security level assessments, creating a closed-loop system that maintains consistent permissions across devices without manual reconfiguration

Inventive Principle:
Principle #23Feedback

2Loss of time

If automatic permission synchronization is implemented, then time consumption is reduced, but system complexity increases

Engineering Contradiction:
Improvetime consumptionVSAvoidsystem complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The system performs preliminary actions by pre-configuring security level information and permission synchronization settings on electronic devices before actual permission changes occur. This allows the automatic synchronization mechanism to operate without complex real-time decision-making, reducing operational complexity while maintaining time efficiency

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system introduces an intermediary mechanism that handles the complexity of permission synchronization between devices. This intermediary layer manages the security level comparisons, configuration information validation, and permission change transmission, shielding users from system complexity while enabling automatic synchronization

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If permission synchronization is enabled across all devices, then synchronization completeness is improved, but security risks increase

Engineering Contradiction:
Improvesynchronization completenessVSAvoidsecurity risks
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system applies local quality by evaluating and applying different synchronization behaviors based on the specific security levels of individual electronic devices. Instead of uniform synchronization across all devices, the system tailors permission synchronization to each device's security characteristics, maintaining completeness where safe while preventing risks where inappropriate

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system changes the parameter of synchronization eligibility based on security level assessments. By dynamically adjusting which devices receive permission synchronization based on their security configurations, the system maintains synchronization completeness for secure devices while blocking potentially harmful synchronization to devices with insufficient security measures

Inventive Principle:
Principle #35Parameter changes

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 (701), where the permission granting information is used to describe a permission granted to an application to invoke software and hardware functions of an 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 (702), where the permission synchronization configuration information is used to describe whether a permission synchronization function of an application is enabled. According to the method, an application permission can be conveniently synchronized between different devices, so that efficiency of application permission synchronization is improved.
