Rotating Display Unit for Vertical Content Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional information devices face operability issues when displaying vertically long content on horizontally long screens, leading to increased screen scrolling and reduced user friendliness, especially when handling large data processing and internet browsing.
Innovation Solution
The information device incorporates a hinge mechanism with a rotational movement mechanism that allows the display unit to rotate 90 degrees, exposing a sub-display screen and input units, thereby transforming the horizontally long screen into a vertically long one, enhancing content viewing and reducing scrolling needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a horizontally long screen is used in conventional information devices, then the device can display wide content, but vertically long content requires increased screen scrolling and reduced user friendliness
Solution Approach 1:
The display unit is made dynamically reconfigurable through a hinge mechanism that allows rotation between horizontal and vertical orientations. The third housing with sub-display screen can be moved between overlapped and exposed states, enabling the system to adapt its display configuration based on content requirements, thereby reducing scrolling for vertically long content while maintaining ease of operation
Solution Approach 2:
The invention adds a vertical dimension to the display configuration by introducing a sub-display screen that can be exposed below the main display screen. This creates a multi-layered display arrangement where vertically long content can span both the main and sub-display screens, effectively extending the vertical display area without increasing scrolling requirements
2Productivity
If the display unit is rotated to transform horizontal screen to vertical screen, then vertically long content can be displayed more efficiently, but the device structure becomes more complex
Solution Approach 1:
The third housing containing the sub-display screen is nested within the display unit structure, allowing it to be moved between an overlapped state (where it is concealed within the display unit) and an exposed state (where it extends below the main display screen). This nesting approach enables vertical screen transformation without adding excessive structural complexity, as the sub-display screen is integrated into the existing hinge mechanism rather than requiring a completely separate rotation system

AI summary
An information device includes: a first housing and a second housing coupled through a hinge mechanism, the second housing being openable to a angle from a closed state where the second housing overlaps with the first housing; a third housing attached to a surface of the second housing on a first housing side through a movement mechanism capable of moving the third housing with respect to the second housing from an overlapped state with the second housing; a first display screen provided on a surface of the third housing on the first housing side; and at least one unit selected from a group of a second display screen, an input mechanism, an output mechanism and an input-output mechanism, the surface being exposed when the third housing is moved with respect to the second housing in a state where the second housing is opened with respect to the first housing.
