Solution Overview
Problem
Existing display devices lack the ability to efficiently adjust their output area based on various content types, limiting their flexibility and user experience.
Innovation Solution
A display device with a flexible design that includes a fixed body and an extended body, a rotational driving unit, and a pinion gear system, allowing the output area to be enlarged or downsized by sliding or rotating components, and a controller that adjusts the display area based on received screen information and direction from external terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display device uses a fixed display area, then the structure is simple and stable, but the adaptability to different content types is poor
Solution Approach 1:
The patent implements a variable display area that can dynamically expand or contract based on content requirements. The display panel is divided into a first display area and a second display area, which can be selectively activated. This dynamic configuration allows the display device to adapt to different content types (full-screen, split-screen, picture-in-picture) without requiring multiple fixed displays, thus improving versatility while maintaining reasonable structural complexity.
Solution Approach 2:
The display area is segmented into multiple independent regions (first display area and second display area) that can be independently controlled. This segmentation enables flexible composition of display configurations, where different segments can be activated based on content needs, resolving the contradiction between adaptability and structural complexity.
2Loss of information
If the display device expands the output area to show multiple contents, then the information display capability is improved, but the visible non-output area increases
Solution Approach 1:
The patent implements a picture-in-picture or nested display configuration where one display area is positioned within or overlapping another display area. This nesting allows multiple contents to be displayed simultaneously with minimal wasted space, as the smaller display area utilizes the space within or near the larger display area rather than adding to the overall device footprint.
Solution Approach 2:
The patent utilizes spatial arrangement in multiple dimensions (overlapping, nested, or adjacent positioning) to maximize information display within the available area. By arranging display areas in different spatial relationships rather than simple linear expansion, the device minimizes visible non-output areas while maximizing information capacity.
3Adaptability or versatility
If the display device uses a flexible display that can be wound, then the adaptability to different screen ratios is improved, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical winding mechanisms with a more straightforward electronic control system that manages the flexible display panel. The flexible display's ability to bend and conform is utilized, but the complexity is reduced by using electronic control and simpler mechanical support structures rather than complex winding mechanisms, thus achieving screen ratio adaptability with manageable device complexity.
