Solution Overview

Problem

Existing extended screens for computers are inconvenient due to their weight, shape, and space requirements, making them difficult to use and carry.

Innovation Solution

An extended screen system comprising three display screens, with two arranged transversely above and one below, forming a diagonal shape that allows for a single placement position for a computer device screen, and featuring rotatable connections for easy folding and carrying.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If three separate extended screens are installed on the top, left, and right sides of the display screen to achieve multi-screen display effect, then the display coverage is improved, but the weight of the extended screen becomes too heavy and the display screen of the computer device will be easily damaged

Engineering Contradiction:
Improvedisplay coverageVSAvoidweight of extended screen
Core Design Contradiction:
Area of stationary objectVSWeight of stationary object

Solution Approach 1:

The patent combines three separate extended screens into a single integrated extended screen structure that can be placed on one display screen of the computer device. This merging approach maintains the multi-screen display functionality while significantly reducing the total weight and structural complexity compared to installing three separate screens on different sides of the display.

Inventive Principle:
Principle #5Merging (Combining)

2Area of stationary object

If three separate extended screens are installed on the top, left, and right sides of the display screen, then the display coverage is improved, but the overall shape becomes equivalent to an inverted capital T shape which is not convenient for a user to watch

Engineering Contradiction:
Improvedisplay coverageVSAvoidconvenience for user to watch
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

By merging three separate extended screens into a single integrated unit, the patent creates a compact structure that is easier for users to view and interact with. The integrated design eliminates the scattered inverted T-shape layout, consolidating the display area into a more cohesive and user-friendly configuration.

Inventive Principle:
Principle #5Merging (Combining)

3Area of stationary object

If two extended screens are installed transversely on the display screen of the computer device, then the display coverage is improved, but it takes up a lot of space which causes inconvenience to the user

Engineering Contradiction:
Improvedisplay coverageVSAvoidspace occupied
Core Design Contradiction:
Area of stationary objectVSVolume of moving object

Solution Approach 1:

The patent merges multiple extended screen functions into a single integrated extended screen that occupies less physical space on the computer device's display screen. This consolidation maintains the multi-screen display capability while significantly reducing the space consumption compared to installing multiple separate extended screens transversely.

Inventive Principle:
Principle #5Merging (Combining)

4Adaptability or versatility

If three separate extended screens are installed to achieve multi-screen display effect, then the display functionality is improved, but it is inconvenient to carry a plurality of separate extended screens

Engineering Contradiction:
Improvemulti-screen display functionalityVSAvoidconvenience to carry
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent combines multiple extended screen functionalities into a single portable extended screen device, making it convenient to carry and transport while maintaining the multi-screen display capability. This integrated design eliminates the need to carry multiple separate extended screens, significantly improving portability.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

An extended screen includes a first display screen, a second display screen, and a third display screen. The second display screen is connected to a top end of the first display screen. The third display screen is connected to a left side edge or a right side edge of the second display screen, so that the first display screen and the third display screen are capable of forming a diagonal shape. When the first display screen and the third display screen form a diagonal shape, one placement position is formed below the third display screen near the first display screen. The placement position is configured for placing a display screen of a computer device. The extended screen includes three display screens, with two display screens arranged transversely above and one display screen arranged below, forming one placement position for placing the display screen of the computer device.
