Double-Sided Display With Sliding Housings And Flexible Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing double-sided display devices have limited flexibility in adjusting screen area and a restricted application range, only allowing for full or half screen usage.
Innovation Solution
A double-sided display device with a housing comprising sliding first and second housings, each equipped with a flexible screen that can be wound and unwound to adjust the display area, driven by a flexible screen drive part and a housing drive part.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single flexible screen is used with bending structure, then the screen area can be adjusted between full and half display, but the flexibility and application range are limited
Solution Approach 1:
The housing is divided into first and second housings that can slide relative to each other, and the flexible screen is segmented into display portion and wound portion. This segmentation allows independent control of display area by sliding the housings, enabling multiple display configurations beyond simple half/full display.
Solution Approach 2:
The patent implements dynamic adjustment of display area through sliding mechanisms that allow the housings to move relative to each other. The flexible screen dynamically transitions between displayed and wound states based on the sliding position, enabling continuous adjustment of display area rather than fixed configurations.
2Area of moving object
If the flexible screen is wound in the housing, then the display area is reduced, but the mechanism for controlling winding and unwinding increases device complexity
Solution Approach 1:
The housing drive part and flexible screen drive part are integrated into a unified system where the sliding of housings simultaneously controls both the mechanical configuration and the screen winding/unwinding. This merging reduces the need for separate control mechanisms and simplifies the overall drive system.
Solution Approach 2:
The flexible screen drive part automatically winds or unwinds the screen based on the sliding motion of the housings. The system self-regulates the screen configuration according to the housing position, eliminating the need for independent control mechanisms and reducing overall device complexity.
