Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing folding electronic devices face issues with insufficient screen accommodating space during folding, leading to pulling or squeezing of the flexible display, which can cause creases and damage.
Innovation Solution
A folding apparatus with a principal axis, bracket assembly, connecting rod assembly, swing arm assembly, and support plate assembly, designed to increase the distance between rotating shafts and axes, preventing interference and enhancing support reliability for the flexible display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the folding apparatus uses a compact structure with rotating shafts close to the principal axis, then the device complexity is reduced, but the screen accommodating space is insufficient causing pulling or squeezing of the flexible display
Solution Approach 1:
The patent positions the rotating shafts at locations away from the principal axis, utilizing the width direction dimension to create sufficient screen accommodating space. This dimensional arrangement allows the flexible display to fold without being pulled or squeezed, while maintaining a relatively compact overall structure through the coordinated movement of brackets and support plates.
2Strength
If the rotating shafts are positioned close to the principal axis, then the structural strength is improved, but the swing arm assembly interferes with the support plate assembly causing damage risk
Solution Approach 1:
The patent segments the folding apparatus into distinct functional assemblies (bracket assembly, connecting rod assembly, swing arm assembly, support plate assembly) with clearly defined spatial relationships. By positioning the rotating shafts away from the principal axis, the patent creates sufficient separation between the swing arm assembly and support plate assembly, preventing interference while maintaining structural integrity through proper connection design.
3Reliability
If the folding apparatus provides sufficient screen accommodating space, then the flexible display is protected from pulling or squeezing, but the device complexity increases
Solution Approach 1:
The patent designs the bracket assembly and support plate assembly to perform multiple functions: they provide screen accommodating space for flexible display protection, maintain structural strength, enable folding motion, and prevent interference between components. This multi-functionality reduces the need for additional specialized components, thereby limiting the increase in device complexity while achieving reliable flexible display protection.

AI summary
A folding apparatus includes a principal axis, a first bracket and a second bracket that are located on two sides of a principal axis along a width direction. A first connecting rod and a second connecting rod are located on two sides of the principal axis along the width direction, and a first swing arm and a second swing arm are located on two sides of the principal axis along the width direction. A first support plate and a second support plate are located on two sides of the principal axis along the width direction. When the first bracket and the second bracket rotate to be positioned face-to-face, and a length of accommodating space of the folding apparatus that accommodates a folded part of a flexible display can be extended.
