Innovation Solution

An electronic device automatically determines the correspondence between applications and SIM cards, allowing for seamless switching between SIM cards based on data service packages, reducing the need for manual user intervention and improving interaction performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual SIM card switching is implemented, then users can control which SIM card is used for specific applications, but the operation process becomes complex and user experience deteriorates

Engineering Contradiction:
ImproveSIM card switching operationVSAvoidSIM card management process
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system automatically matches applications with SIM cards based on pre-configured correspondences, enabling the device to serve itself without requiring manual user intervention for SIM card switching decisions

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The correspondence between applications and SIM cards is pre-configured in advance, allowing the system to automatically determine the appropriate SIM card when an application is launched, eliminating the need for manual switching at the time of use

Inventive Principle:
Principle #10Preliminary action

2Productivity

If automatic SIM card switching is implemented, then operation simplicity improves, but the need for user control and configuration increases system complexity

Engineering Contradiction:
ImproveInteraction performanceVSAvoidAutomatic matching system
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The device automatically establishes and manages the correspondence between applications and SIM cards, performing the matching function autonomously without requiring complex user configurations or interventions during operation

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The automatic matching system provides a universal solution that works across different applications and SIM card combinations, handling various scenarios through a single integrated mechanism rather than requiring separate configurations for each case

AI summary

This application provides a method for automatically switching SIM cards and an electronic apparatus, and relates to the field of terminal technologies. The method is applied to an electronic device. A first application and a second application are installed on the electronic device, and a first SIM card and a second SIM card are preconfigured in the electronic device. The method includes: automatically determining, by the electronic device, that a correspondence between an application and a SIM card is that the first application corresponds to the first SIM card and the second application corresponds to the second SIM card; and when performing a data service by using the first SIM card, if detecting an operation of enabling the second application by a user, switching to the second SIM card to perform a data service. A data service package of the first SIM card is different from a data service package of the second SIM card. This technical solution helps reduce operations performed by the user on the electronic device, helps improve intelligent interaction between the electronic device and the user, and improves user experience to some extent.
