Foldable Multi-Screen Layout With Stacked Screen Assemblies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing folding mobile phones require a large space for both the main and auxiliary display screens, leading to a thicker and heavier design due to the tiled arrangement of these devices, which compromises battery capacity and overall device thickness.
Innovation Solution
A stack arrangement of the first and second screen assemblies on opposite sides of the main body, with their target surfaces overlapping, allowing for a more compact design that saves space for improved battery capacity and additional device components.

Engineering Contradiction Analysis
1Area of moving object
If the main screen and auxiliary screen devices are arranged in a tiled layout, then both screens can be fully displayed, but the occupied machine body area increases leading to thicker and heavier device design
Solution Approach 1:
The patent transitions from a two-dimensional tiled arrangement to a three-dimensional stacked arrangement. The first and second screen assemblies are positioned at different heights along the thickness direction of the main body, with their target surfaces overlapping in the projection view. This vertical stacking allows both screens to be accommodated within a smaller footprint area while maintaining full display functionality.
Solution Approach 2:
The screen assemblies are nested within the main body structure in a stacked configuration. The first screen assembly and second screen assembly are both located inside the main body, with their target surfaces overlapping, creating a nested spatial arrangement that maximizes space utilization and reduces the overall device footprint.
2Area of moving object
If the main screen and auxiliary screen devices are arranged in a tiled layout, then both screens can be fully displayed, but the device becomes thicker and heavier
Solution Approach 1:
By arranging screen assemblies in the thickness direction rather than spreading them out in the plane, the patent reduces the overall device footprint. This vertical integration allows for more efficient space utilization, potentially reducing the amount of structural material needed and thereby decreasing device weight.
Solution Approach 2:
The patent combines multiple screen assemblies into a compact stacked structure within the main body. By merging the spatial requirements of multiple screens into a single integrated volume rather than separate planar areas, the overall device structure can be optimized for reduced weight and size.
3Area of moving object
If the main screen and auxiliary screen devices are arranged in a tiled layout, then both screens can be fully displayed, but the battery capacity is reduced due to less available space
Solution Approach 1:
The stacked arrangement in the thickness direction creates more available volume within the device footprint for battery placement. By utilizing the vertical dimension for screen assemblies, the patent frees up horizontal space that can be allocated to larger battery capacity while maintaining the same overall device footprint.
