Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current display screen protective covers for pads primarily focus on protection rather than providing additional display functionality, limiting the versatility of pad devices.

Innovation Solution

Incorporating a foldable secondary display screen that can switch between display modes by detecting its state, allowing the primary screen to be shaded or combined with the secondary screen for diverse display applications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a display screen protective cover is added to protect the pad, then the protection capability is improved, but the display functionality is lost

Engineering Contradiction:

Improveprotection capabilityVSAvoiddisplay functionality

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The protective cover is designed with a second display screen that can function both as a protective element and as a display device. When folded over, it protects the first display screen while simultaneously providing display capabilities through the second screen, enabling multiple functions from a single structure.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The second display screen is integrated within the protective cover structure, nesting the display functionality inside the protective element. The cover contains the second screen within its folds, allowing the display function to be embedded within the protective structure rather than being separate.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Adaptability or versatility

If a foldable display screen is added to provide multiple display modes, then the versatility is improved, but the device complexity increases

Engineering Contradiction:

Improvedisplay modesVSAvoidstructure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The display system is segmented into two independent display screens - a first display screen integrated into the pad body and a second display screen integrated into the protective cover. This segmentation allows each screen to function independently or in combination, providing multiple display modes without requiring a completely complex integrated system.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The protective cover with the second display screen is designed to be dynamically foldable and movable, allowing it to transition between different positions (folded over, unfolded, angled). This dynamic structure enables multiple display configurations and modes while maintaining a relatively simple base structure that leverages the natural flexibility of the cover.

Inventive Principle:

Principle #15Dynamics

AI summary

An electronic device having a plurality of display modes is described. The electronic device includes a first and a second display screen, wherein the second display screen is a foldable display screen. The display method includes detecting a screen state of the second display screen; displaying in the first display mode when the screen state is a first state; displaying in the second display mode when the screen state is a second state, wherein the first display screen is divided into a first part shaded by the second display screen and a second part. In the second display mode, the first picture is displayed using a combination of at least part of the second display screen and the second part of the first display screen while a second picture is displayed on the at least part of the second display screen.
