Solution Overview

Problem

Mobile devices with touch screens are vulnerable to scratches and damage due to existing cover designs that either expose the screen or require frequent opening, leading to inconvenience and wear.

Innovation Solution

A mobile device and method that detects the type and position of a cover with a screen projection portion, adapting the display to coincide with the cover's size and position, allowing for secure protection and one-hand operation by automatically switching the screen display.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a cover device is used to protect the mobile device exterior, then the exterior is protected from damage, but the touch screen becomes vulnerable to scratches when exposed for use

Engineering Contradiction:
Improveexterior protectionVSAvoidtouch screen scratches
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The cover is divided into multiple portions: a first cover portion that can be folded back to expose the touch screen, and a second cover portion that remains closed to protect the exterior. This segmentation allows different parts of the device to have different protection states simultaneously.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cover is designed as a flip-type cover that can dynamically change its state between closed (protecting exterior) and partially open (exposing touch screen). The first cover portion can be folded back dynamically to allow touch screen access while maintaining overall cover protection.

Inventive Principle:
Principle #15Dynamics

2Object-affected harmful factors

If a flip-type cover is used to fully cover the mobile device, then the touch screen is protected from scratches, but the user must open the cover each time to use the touch screen, causing inconvenience and wear

Engineering Contradiction:
Improvetouch screen scratchesVSAvoiduser convenience
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The cover is segmented into a first cover portion and a second cover portion. The first cover portion can be folded back independently to expose the touch screen for use, while the second cover portion remains closed to maintain protection. This allows the user to access the touch screen without opening the entire cover.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cover protection is extended to another dimension by adding a transparent protective layer over the touch screen. This additional layer allows the touch screen to remain exposed for use while still being protected from scratches and damage.

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

3Ease of operation

If the touch screen is exposed for user interaction, then the user can easily access and manipulate the device, but the touch screen becomes vulnerable to shocks and scratches

Engineering Contradiction:
Improvetouch screen accessibilityVSAvoidtouch screen damage
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The first cover portion is designed to be dynamically foldable, allowing the user to expose the touch screen when needed for interaction, and then fold it back when not in use to restore protection. This dynamic state change enables both accessibility and protection.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

A transparent protective layer is added over the touch screen, creating an additional dimension of protection. This layer allows touch input to pass through while protecting the touch screen from scratches and shocks during normal use.

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

AI summary

A mobile device control method for displaying information on a touch screen of a mobile device is provided. The method includes determining a type of a cover for the mobile device, the cover having a screen projection portion, detecting a gesture or a trigger, and displaying a screen corresponding to a current state of the mobile device on the touch screen depending on the type of the cover, in response to the detection of the gesture or the trigger.
