Foldable Display Hinge Assembly With Door Plate Swing Arm
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current foldable electronic devices have poor stability and a large size due to complex movement cooperation mechanisms in their folding assemblies, which occupy significant space when folded.
Innovation Solution
A folding assembly design that combines door plate and swing arm structures, utilizing sliding grooves and synchronization mechanisms to simplify movement cooperation, enhance stability, and reduce size by forming a water drop shape when folded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If complex movement cooperation mechanisms are used in the folding assembly, then the folding function can be implemented, but the stability of the folding assembly deteriorates and the size increases
Solution Approach 1:
The patent merges the door plate structure and swing arm structure into a single integrated door plate swing arm component. This reduces the number of separate parts and movement cooperation mechanisms from multiple independent components to a unified structure that works with the shaft base and housing, thereby improving stability while maintaining the folding function.
Solution Approach 2:
The folding assembly is segmented into distinct functional zones: the shaft base provides rotational support, the door plate swing arm provides the folding movement, and the housing provides structural support. This clear segmentation allows each component to perform its specific function efficiently without requiring complex cooperation mechanisms between overlapping components.
2Adaptability or versatility
If complex movement cooperation mechanisms are used in the folding assembly, then the folding function can be implemented, but the space occupied increases causing large size when folded
Solution Approach 1:
By combining the door plate and swing arm into a single integrated component, the patent eliminates the space required for separate door plate and swing arm structures and their associated cooperation mechanisms. This integration allows the folding assembly to achieve a compact folded state with size reduced to less than 14mm while maintaining full folding functionality.
Solution Approach 2:
The door plate swing arm is rotatably connected to the shaft base and the housing, creating a nested arrangement where components are positioned within each other's spatial envelope. When folded, the structure collapses into a compact nested configuration that minimizes the overall volume occupied by the folding assembly.
