Contact Info Retrieval and Display for Smartphones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users with multiple subscriber identity cards on their smartphones face inconvenience when contacts change, as others may not know the current contact information, leading to difficulties in communication.
Innovation Solution
An electronic device with a processor, memory, and communication module that automatically retrieves and displays changed contact information from an external device, allowing users to easily identify and use the current contact for calls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a smartphone stores multiple contact information for a counterpart, then the user can maintain multiple communication channels, but it becomes difficult for others to know the current contact information
Solution Approach 1:
The patent applies visual differentiation (analogous to color changes) by displaying old contact information with a strike-through effect and new contact information without strike-through. This allows users to immediately distinguish between outdated and current contact information, solving the visibility problem while maintaining multiple contact records
2Reliability
If contact information is manually updated in the phonebook, then the current contact can be recorded, but the process requires user intervention and may be overlooked
Solution Approach 1:
The patent implements preliminary action by automatically detecting contact information changes from messaging applications before the user needs to make a call. The system proactively retrieves updated contact information, compares it with stored information, and prepares the updated data for display, eliminating the need for manual updates
Solution Approach 2:
The patent employs feedback mechanisms by continuously monitoring messaging applications for contact information changes and automatically comparing new information with stored contact data. This closed-loop feedback ensures contact information remains current without requiring user intervention
3Productivity
If the system automatically retrieves contact information from messaging apps, then updated contact data can be obtained, but additional permissions and data access are required
Solution Approach 1:
The patent applies universality by designing a contact information retrieval system that works across multiple messaging applications (SMS, MMS, instant messaging). The same retrieval mechanism and data processing logic are used regardless of the source application, reducing overall system complexity despite handling multiple data sources
Data Source
AI summary
An electronic device having a call handling function and operation method therefor are provided. The electronic device may include a display, a memory configured to store first contact information of a counterpart, a transceiver, and at least one processor. The at least one processor may be configured to control for sending a request for first contact information of the counterpart through the transceiver to an external electronic device in response to a user request, receiving second contact information of the counterpart through the transceiver from the external electronic device, and presenting the first contact information and second contact information on the display.
