Electronic Device Contact Display with Service Provider Matching

Solution Overview

Problem

Electronic devices with multiple SIM cards struggle to automatically recommend the most suitable SIM card for a call situation, leading to inefficient communication as they typically rely on user selection rather than intelligent service provider matching.

Innovation Solution

The method involves displaying contact information alongside service provider information, allowing the device to attempt data transmission using the appropriate SIM card based on user input and highlighting matching service providers to recommend the optimal SIM card for communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the electronic device relies on user selection for SIM card choice, then the device complexity is reduced, but the adaptability to different call situations deteriorates

Engineering Contradiction:

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The electronic device automatically determines the appropriate SIM card by comparing service provider information of installed SIM cards with the service provider of the contact, eliminating the need for manual user selection while adapting to different call situations

Inventive Principle:

Principle #25Self-service

2Ease of operation

If the electronic device provides service through a SIM card selected by user, then the ease of operation is maintained, but the loss of information regarding optimal service provider matching increases

Engineering Contradiction:

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The device provides feedback to the user by displaying service provider information associated with each SIM card, enabling the user to make informed decisions about which SIM card to use for contacting a specific service provider

Inventive Principle:

Principle #23Feedback
