Solution Overview

Problem

In a screen lock state, users face inconvenience due to fixed icon positions on mobile devices, leading to potential misinterpretation of missed calls or messages, even when none are present, as icons remain displayed in gray form without dynamic adjustment.

Innovation Solution

The method dynamically adjusts the displaying positions of icons on a mobile device's screen based on the number of outstanding event types, such as missed calls or messages, by splitting the screen into areas and displaying icons in blocks proportional to the event count, allowing for clear and organized presentation of event types and their occurrence times.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If icons are displayed at fixed positions on the screen in screen lock state, then the display structure is simple and stable, but users may mistakenly interpret gray icons as actual events even when none are present

Engineering Contradiction:
Improveaccuracy of event indicationVSAvoiddisplay adjustment mechanism
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic icon positioning where the display position of icons changes based on the number of outstanding events. When events exist, icons are displayed at specific positions; when no events exist, icons are hidden or positioned differently. This dynamic adjustment resolves the contradiction by making the display adaptive rather than static, ensuring accurate event indication without misleading gray icons.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes display parameters (icon position, visibility) based on the state of outstanding events. By modifying display parameters dynamically according to event count, the system accurately reflects the actual event status while maintaining simple operation for users.

Inventive Principle:
Principle #35Parameter changes

2Loss of information

If multiple outstanding event types are displayed simultaneously, then information completeness is improved, but the display becomes cluttered and harder to read

Engineering Contradiction:
Improvecompleteness of event informationVSAvoidusability of display
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent segments the display area into different regions and distributes icons of different event types to specific segments. This segmentation allows multiple event types to be displayed simultaneously while maintaining clear visual separation, preventing clutter and improving readability while preserving information completeness.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If the screen remains unlocked for easy access, then operation convenience is improved, but mistouching may occur causing unintended function activation

Engineering Contradiction:
Improveaccess convenienceVSAvoidprevention of mistouching
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary action by displaying preview information of outstanding events on the locked screen. This allows users to check events before fully unlocking, providing convenience while maintaining security. The preliminary display of information satisfies the need for access convenience without requiring the screen to remain permanently unlocked.

Inventive Principle:
Principle #10Preliminary action

AI summary

A method for prompting an outstanding event in screen lock state, an electronic device thereof, and a storage medium thereof are provided. In the present method, at least one outstanding event type is obtained first, wherein a corresponding occurrence time of each outstanding event type is greater than 0. Next, an amount of the outstanding event type is counted. Finally, a displaying position of an icon of each outstanding event type on a screen of the electronic device is adjusted according to the amount of the outstanding event types. As a result, a user can get the outstanding event type and the occurrence time thereof by the information shown on the screen, so as to increase the convenience of using the electronic device.
