Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current foldable electronic devices face issues with complex hinge structures that lead to high manufacturing costs, assembly inefficiencies, and inadequate support for flexible displays, which can result in deformation, creases, or breakage during folding.
Innovation Solution
A foldable electronic device with a hinge featuring a main shaft and symmetrically disposed first and second foldable assemblies, each comprising rotating members and connecting rods, that allow for folding and unfolding while providing continuous planar support to the flexible display through multiple support surfaces, minimizing extrusion or stretching forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hinge with adjustable length is used to prevent flexible display from being squeezed, then the flexible display protection is improved, but the structure becomes complex and manufacturing costs increase
Solution Approach 1:
The hinge is divided into multiple independent components: first and second rotating members, first and second connecting rods, and first and second bodies. Each component performs a specific function, allowing the hinge to achieve adjustable length through coordinated movement of these segmented parts rather than using a single complex adjustable mechanism.
Solution Approach 2:
The hinge employs dynamic connections where the connecting rods are rotatably connected to the rotating members and bodies, allowing the hinge length to change dynamically during folding and unfolding. This dynamic structure adapts to different states (folded, unfolded, partial folding) to protect the flexible display without requiring a statically complex adjustable mechanism.
2Reliability
If a hinge with adjustable length is used to prevent flexible display from being squeezed, then the flexible display protection is improved, but assembly efficiency decreases due to complex assembly process
Solution Approach 1:
The hinge is divided into multiple independent components: first and second rotating members, first and second connecting rods, and first and second bodies. Each component performs a specific function, allowing the hinge to achieve adjustable length through coordinated movement of these segmented parts rather than using a single complex adjustable mechanism.

3Reliability
If multiple support surfaces are provided to ensure planar support for flexible display, then the flexible display support is improved, but the number of parts increases
Solution Approach 1:
The first and second bodies serve multiple functions: they provide structural support for the flexible display through their support surfaces, act as connection points for the connecting rods, and contribute to the overall hinge length adjustment mechanism. This multi-functionality reduces the need for separate dedicated support components.
Solution Approach 2:
The hinge is divided into multiple independent components: first and second rotating members, first and second connecting rods, and first and second bodies. Each component performs a specific function, allowing the hinge to achieve adjustable length through coordinated movement of these segmented parts rather than using a single complex adjustable mechanism.
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 hinge effectively supports the flexible display, preventing deformation and ensuring user experience by maintaining planar support and reducing manufacturing and assembly costs through a simple structure with fewer parts.
Implementation Method 1
A first end of the first rotating member is rotatably connected to the main shaft, and a second end of the first rotating member is slidably connected to the first body
