Solution Overview

Problem

Users face inconvenience when receiving phone calls while using applications on mobile devices, as they must temporarily stop the application to answer the call and then resume it afterwards, lacking seamless multitasking between calls and app usage.

Innovation Solution

A mobile device system that allows displaying an application's screen on top of a call reception screen and dynamically changes the call reception mode based on user input, enabling real-time checking of information like emails or calendar reservations during calls, and automatically sends declining messages or captures images if the user does not respond within a set time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a user receives a phone call while executing an application, then the user can answer the phone call, but the user must temporarily stop the application and execute it again after the call, causing inconvenience

Engineering Contradiction:
Improveease of multitasking between application and phone callVSAvoidtime to stop and resume application
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The screen is segmented into multiple display regions, with the first region showing the application execution screen and the second region showing the phone call reception screen. This allows both the application and phone call interface to be visible simultaneously, enabling users to multitask without fully switching between applications.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a spatial dimension to the interface by displaying the application screen and phone call reception screen in different screen regions simultaneously. This transforms the traditional single-focus interface into a multi-region display, allowing users to access both functions at the same time without temporal interruption.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If a phone call is received from a specific counterpart, then contact history and location information can be provided, but the user cannot execute the application and receive the phone call at the same time

Engineering Contradiction:
Improvecapability to access multiple information types during callVSAvoidease of simultaneous application execution and call reception
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent merges the application execution screen and the phone call reception screen into a single unified interface displayed on the same device screen. This combination allows users to access application functionality, contact information, location data, and call reception all simultaneously without needing to switch between separate applications or interfaces.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The first screen region is designed to display execution screens of various applications, making the interface universal and adaptable to different application types. This multi-functional design allows the same interface structure to support email checking, calendar reservations, and other applications while receiving calls simultaneously.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Loss of information

If the user wants to check additional information during a call, then the information can be displayed, but the interface becomes more complex requiring multiple screen regions

Engineering Contradiction:
Improveaccess to additional information during callVSAvoidinterface complexity with multiple screen regions
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

Different screen regions are assigned specific functions: the first region for application content and the second region for call reception information. This local differentiation allows the interface to present complex information in an organized manner, with each region optimized for its specific purpose, reducing the perceived complexity for users.

Inventive Principle:
Principle #3Local quality

AI summary

A mobile device including a wireless communication processor configured to receive a call signal from an external device; a display; and a controller configured to display a first screen on the display including options for responding to the received call signal, in response to a touch and drag input in a specific direction, display a second screen on the first screen, respond to the received call signal in a hold mode when the second screen is touched and dragged in a first direction to a first distance, respond to the received call signal in a normal mode when the second screen is touched and dragged in the first direction to a second distance greater than the first distance, and respond to the received call signal in a speakerphone mode when the second screen is touched and dragged in the first direction to a maximum extension of the second screen.
