Multi-SIM Selector Module Automates Subscriber Identity Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of multi-SIM mobile communication devices face inconvenience when needing to manually select SIM cards in areas covered by multiple communication service providers, as this process is time-consuming and inefficient, especially when considering varying cost rates and service quality across different providers.
Innovation Solution
A processing device executes a selector module that determines the most suitable SIM card based on cost rates and other factors such as location and time, automatically selecting the SIM card for communication services without user intervention, using a cost table to compare rates and display the selected SIM card on the device's screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual SIM card selection is implemented, then users can control which communication service provider is used, but the process becomes time-consuming and inefficient
Solution Approach 1:
The system enables automatic SIM card selection by having the device itself evaluate and choose the appropriate SIM card based on cost rates and service conditions, eliminating the need for manual user intervention while maintaining optimal service selection
Solution Approach 2:
The system pre-calculates and stores cost rates and service conditions for multiple communication service providers in advance, allowing rapid automatic selection when a SIM card is needed without time-consuming real-time analysis
2Ease of operation
If automatic SIM card selection is implemented, then user effort is reduced, but the device complexity increases
Solution Approach 1:
The system introduces a selection module as an intermediary component that automatically evaluates cost rates and service conditions to determine the optimal SIM card, simplifying the user interface while managing the complexity of automatic selection logic
3Adaptability or versatility
If multiple SIM cards are installed, then users can access multiple communication service providers, but the difficulty of selecting the most suitable SIM card increases
Solution Approach 1:
The system continuously monitors and compares cost rates and service conditions from multiple communication service providers, using feedback mechanisms to automatically identify and select the most suitable SIM card based on current conditions and user needs
