Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable electronic devices with flexible screens face issues such as damage to the bendable area when folded or inability to fully flatten due to poorly designed supporting structures, and existing linkage structures increase the overall thickness, causing inconvenience.
Innovation Solution
A foldable electronic device with a central base, track portion, lifting plate, and arc-shaped sliders, featuring a torque module and transmission members that allow synchronized pivoting and sliding of wing members to create a yielding space for the flexible screen, using helical protrusions and grooves for synchronized movement and friction control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing linkage structures are used to provide yielding spaces for the bendable area, then the flexible screen can be protected during folding, but the moving distance of internal elements becomes long and the overall thickness of the shell increases
Solution Approach 1:
The patent employs arc-shaped sliders and arc-shaped slideways instead of linear movement structures. The first and second inner arc-shaped sliders move along arc-shaped trajectories within the central base, creating a compact yielding space that accommodates the bendable area during folding without requiring long linear displacement. This curved path design reduces the overall thickness while maintaining sufficient yielding space for screen protection.
Solution Approach 2:
The patent implements a nested structure where the first and second panel bodies are pivotally connected to the central base, and the wing members are nested within the space defined by the panel bodies and central base. The lifting plate moves vertically within the confined space created by the pivoting wing members, creating a compact nested arrangement that provides yielding space without increasing overall device thickness.
2Shape
If the lifting plate is positioned at the highest position in unfolded state, then the flexible screen can be fully flattened, but the structure requires complex linkage mechanisms
Solution Approach 1:
The patent combines multiple functions into integrated components. The wing members serve dual purposes: they pivot to create yielding space during folding and simultaneously support the lifting plate to achieve screen flattening during unfolding. The arc-shaped sliders and slideways are integrated into the central base structure, eliminating the need for separate linkage mechanisms while maintaining the required motion paths for both folding and flattening operations.
Solution Approach 2:
The central base structure serves multiple functions: it provides the pivot points for the panel bodies, contains the arc-shaped sliders that guide the wing members' motion, supports the lifting plate's vertical movement, and creates the yielding space for the bendable area. This multi-functional design eliminates the need for separate specialized linkage mechanisms for each function, reducing overall device complexity.
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 device effectively supports the flexible screen in both unfolded and folded states without increasing thickness, ensuring the screen is fully flattened or allowed to bend smoothly, enhancing user convenience.
Implementation Method 1
The synchronous module further comprises a first helical protrusion, a second helical protrusion, a first helical groove and a second helical groove, wherein the first helical protrusion is matched to be accommodated in the first helical groove, and the second helical protrusion is matched to be accommodated in the second helical groove.
Implementation Method 2
the synchronous slider body is able to drive the first transmission member and the second transmission member to rotate synchronously and reversely when the synchronous slider body slides
