Telescopic Display Mechanism for Variable Area Without Thickness Increase
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current foldable screens have a large thickness in their folded state due to superimposed layers, which affects user experience.
Innovation Solution
A display device with a motion mechanism that includes skid rails and telescopic elements, allowing display groups to move along a direction, enabling extension and contraction of the display region without superimposed screens, thereby maintaining a smaller thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If foldable screens use superimposed layers to achieve extension, then display area is extended, but thickness increases
Solution Approach 1:
The display screen is divided into multiple display groups (first display groups, second display groups, third display groups) that can be independently moved along the first direction. Each display group contains light-emitting elements that can be selectively activated, allowing the display area to be extended without increasing thickness by moving segments rather than stacking them.
Solution Approach 2:
The display groups are made movable relative to each other along the first direction through the motion mechanism. The display can dynamically transition between different display modes (first display mode with all groups in middle region, second display mode with groups distributed across middle and extension regions) to achieve variable display areas without permanent thickness increase.
2Area of moving object
If display groups are moved along the first direction to extend display region, then display area is extended, but device complexity increases
Solution Approach 1:
The motion mechanism serves multiple functions: it guides the movement of different display groups along the first direction, enables transition between display modes, and facilitates the extension and contraction of the display region. This multi-functionality reduces the need for separate mechanisms for each display group, thereby managing complexity.
Solution Approach 2:
The display groups are arranged along the first direction with the middle display region containing all groups and the extension display region providing additional space. The telescopic elements are disposed between adjacent display groups, allowing compact arrangement when not in use and expansion when needed, similar to nested structures.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for the extension of the display area while preventing an increase in thickness, offering a more user-friendly experience by maintaining a compact form when not in use.
Implementation Method 1
the skid rails include magnetic wheel respectively connected to the first display groups, the second display groups, and the third display groups, and magnetic rails movably connected to the magnetic wheels
