Telescopic Display Mechanism With Balance Rods to Prevent Screen Tilt
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current slide-roll display devices experience inconsistent telescoping lengths of folding telescopic brackets, leading to tilting of the flexible display screen, potential collisions with the device housing, and a negative impact on user experience and screen longevity.
Innovation Solution
The implementation of a telescopic mechanism with m folding telescopic frames and m-1 balance connecting rod groups, where each balance connecting rod group is disposed between adjacent frames, ensuring synchronized telescoping and reducing the likelihood of tilting by maintaining consistent frame lengths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple folding telescopic brackets are used without balance connecting rods, then the telescopic mechanism can achieve basic telescoping function, but the telescoping lengths of the brackets become inconsistent causing the display screen to tilt
Solution Approach 1:
The balance connecting rod acts as an intermediary component between adjacent folding telescopic brackets. It transfers and synchronizes the telescoping motion between brackets, ensuring they move at the same speed and maintain consistent lengths, thereby preventing screen tilting while preserving the telescoping function.
2Device complexity
If the telescopic assembly lacks balance connecting rods, then the structure remains simple, but the display screen may collide with the housing during tilting
Solution Approach 1:
The balance connecting rod is installed in advance between adjacent folding telescopic brackets to pre-establish a synchronization mechanism. This preliminary structural arrangement ensures that during telescoping operation, the brackets maintain consistent lengths from the outset, preventing screen tilting and potential collisions with the housing before they occur.
3Ease of manufacture
If folding telescopic brackets telescope at different speeds, then the mechanism can accommodate manufacturing tolerances, but the display screen tilts and service life is reduced
Solution Approach 1:
The balance connecting rod creates a mechanical feedback system between adjacent folding telescopic brackets. As one bracket telescopes, the connecting rod transmits the motion to adjacent brackets, providing real-time mechanical feedback that synchronizes their telescoping speeds. This ensures consistent screen orientation and prevents damage, extending the display screen's service life while accommodating manufacturing variations.
