Solution Overview

Problem

Existing mobile device interfaces lack intuitive methods for navigating and presenting information efficiently, particularly in calendar applications, making it difficult for users to quickly access and view relevant content.

Innovation Solution

A method and apparatus for mobile terminals that utilize a touchscreen interface to allow users to navigate calendar content by selecting indices, where the display unit changes the content presentation direction based on the relative position of the selected index to the highlighted index, either horizontally or vertically, ensuring seamless and intuitive content transitions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional scroll bar display is used for calendar navigation, then the interface structure is simple, but the user cannot quickly observe corresponding information by operating only the desired date

Engineering Contradiction:
Improveease of navigationVSAvoidinterface complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The calendar interface is segmented into multiple interactive date buttons arranged in a grid layout, allowing users to directly access specific dates without scrolling. Each date cell becomes an independent interactive element that can be selected to display corresponding event information.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The interface transitions from a one-dimensional scroll bar navigation to a two-dimensional grid layout where dates are arranged in rows and columns. This dimensional change enables direct visual access to any date by simply looking at the grid position, eliminating the need for sequential scrolling through the calendar.

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

2Loss of information

If multiweek calendar with event list overlay is displayed, then comprehensive information is presented, but the display space is limited and may clutter the interface

Engineering Contradiction:
Improveinformation completenessVSAvoiddisplay area
Core Design Contradiction:
Loss of informationVSArea of stationary object

Solution Approach 1:

Event information is extracted from the main calendar grid and presented in a separate overlay panel or side panel. This allows the calendar grid to remain clean and uncluttered while providing comprehensive event details in a dedicated information display area that can be shown or hidden as needed.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The event information panel is nested within or adjacent to the calendar view, allowing both the calendar and event details to be displayed simultaneously in a layered arrangement. The event panel can be collapsed or expanded to adjust the visible area dynamically.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

A screen display method and apparatus of a mobile terminal is provided for changing a screen represented by an index to another screen represented by a newly selected index. A screen display method of a mobile terminal includes displaying a page represented by an index, the page including an index region having a plurality of indices and a content region displaying content corresponding to the index highlighted in the index region, selecting a new index in the index region according to a selection input, and changing the page represented by the highlighted index for a new page represented by the new index, the new page appearing in a direction from a position of the new index to a position of the highlighted index.
