Solution Overview
Problem
Existing mobile terminals with flexible display screens lack an automatic folding mechanism, resulting in poor user experience due to manual operation.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible display screen is applied in a mobile terminal, then the screen area is enlarged and overall dimension is reduced, but automatic folding or unfolding cannot be implemented and user experience is poor
Solution Approach 1:
The folding device enables the flexible display screen to fold and unfold automatically through the power assembly driving the movement assembly, eliminating the need for manual operation. The system serves itself by integrating the driving mechanism directly with the display structure, allowing autonomous folding/unfolding cycles.
Solution Approach 2:
The patent replaces manual mechanical folding with an automated power-driven mechanism. The power assembly (electric motor) converts electrical energy to mechanical motion, which is then transmitted through the movement assembly to control the folding action, substituting human hand operation with an electromechanical system.
2Extent of automation
If a powered folding mechanism is added to enable automatic folding, then user experience is improved, but device complexity increases
Solution Approach 1:
The folding device is divided into distinct functional modules: power assembly (motor), transmission assembly (gears and linkages), and folding mechanism (hinges and support structures). This segmentation allows each component to be optimized independently and simplifies the overall design by distributing complexity across separate, manageable units.
Solution Approach 2:
The movement assembly serves multiple functions: it converts rotational motion from the power assembly into linear motion, provides structural support for the flexible display, and enables both folding and unfolding operations through bidirectional actuation. This multi-functionality reduces the need for separate dedicated components.
