Multi-Foldable Display Metal Plate for Dual-Curvature Hinges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-foldable electronic devices face challenges in accommodating elastic deformation of back plates with different curvatures due to the stiffness difference between the back plate and display substrate, particularly when multiple folding directions and radii of curvature are involved.
Innovation Solution
A multi-foldable electronic device is designed with a flexible metal plate featuring differential patterns in the folding areas to support stable in-folding and out-folding operations, utilizing distinct patterns for each folding unit to accommodate varying curvatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a single touchscreen display device is used, then portability is improved, but functionality and productivity are limited
Solution Approach 1:
The electronic device is divided into multiple independent display panels that can be separated and used individually, or combined to form a larger display system. Each panel functions as a complete device when separated, providing portability, while combining multiple panels delivers enhanced functionality for productivity tasks.
2Adaptability or versatility
If multiple electronic devices are used to achieve multi-tasking, then functionality is improved, but portability and ease of operation deteriorate
Solution Approach 1:
Multiple display panels are merged into a single integrated device that maintains the operational simplicity of one device while providing the multi-tasking capability of multiple devices. The panels can be arranged in various configurations and controlled through a unified interface.
Solution Approach 2:
Each display panel is designed to be universally functional, capable of operating independently as a complete device or combining with other panels. This multi-functionality allows the system to adapt to different usage scenarios while maintaining ease of operation through consistent controls.
3Adaptability or versatility
If multiple electronic devices are connected via wireless communication, then functionality is improved, but power consumption and device complexity increase
Solution Approach 1:
The connection architecture is designed with asymmetry where one panel acts as a master controller and other panels serve as dependent displays. This reduces the need for full bidirectional wireless communication between all panels, thereby reducing overall power consumption while maintaining collaborative functionality.
