Solution Overview

Problem

Existing foldable screens face challenges in effectively utilizing the increased display area when transitioning from a folded to an unfolded state, leading to suboptimal content display and user experience.

Innovation Solution

A display method that adjusts the dock bar to accommodate a greater number of service entries when the screen is unfolded, utilizing historical usage data and user preferences to optimize content display and accessibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of moving object

If the dock bar displays a fixed number of service entries in folded state, then the interface layout remains stable, but the unfolded display area cannot be fully utilized

Engineering Contradiction:
Improvedisplay area utilizationVSAvoidinterface layout complexity
Core Design Contradiction:
Area of moving objectVSDevice complexity

Solution Approach 1:

The dock bar dynamically adjusts its capacity and layout based on the foldable screen's state (folded or unfolded). When unfolded, the dock bar expands to display more service entries; when folded, it maintains a compact layout with fewer entries. This dynamic adaptation resolves the contradiction by allowing full utilization of the unfolded display area while maintaining layout stability in folded state.

Inventive Principle:
Principle #15Dynamics

2Productivity

If more service entries are displayed in the dock bar when unfolded, then user access efficiency improves, but the interface design complexity increases

Engineering Contradiction:
Improveservice access efficiencyVSAvoidinterface design complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The service entries in the dock bar are segmented into different groups or categories. When the screen is unfolded, additional service entries are displayed by expanding existing groups or adding new segments to the dock bar. This segmentation approach allows efficient access to more services while maintaining a structured and manageable interface design, avoiding overwhelming complexity.

Inventive Principle:
Principle #1Segmentation

3Area of moving object

If the dock bar expands to fill the unfolded screen, then display area utilization improves, but the original compact layout is compromised

Engineering Contradiction:
Improvedock bar display areaVSAvoidlayout consistency
Core Design Contradiction:
Area of moving objectVSStability of the object's composition

Solution Approach 1:

The dock bar implements dynamic layout adjustment based on screen state. In folded state, it maintains its original compact layout with optimized spacing. When unfolded, it dynamically expands by adjusting the number of displayed entries, spacing, and arrangement patterns. This dynamic behavior allows the dock bar to adapt to different display areas while maintaining layout consistency within each state, resolving the contradiction between area utilization and layout stability.

Inventive Principle:
Principle #15Dynamics

AI summary

This application discloses a display method for a foldable screen and an electronic device. The method includes: displaying a first group of service entries in a first dock bar when the electronic device detects that a foldable screen is in a folded state; and displaying a second group of service entries in a second dock bar when the electronic device detects that the foldable screen is in an unfolded state. A quantity of service entries in the second group of service entries is greater than a quantity of service entries in the first group of service entries. The first dock bar is a dock bar in a display area of the foldable screen in the folded state, and the second dock bar is a dock bar in a display area of the foldable screen in the unfolded state.
