Elastic Assembly Maintains Flush Housing Surfaces for Flexible Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display screens face issues with mold marks and uneven support when the second housing slides out of the first housing due to a level difference between the surfaces, leading to weak support and potential damage.
Innovation Solution
The display apparatus incorporates an elastic assembly that provides an elastic force to the second housing, ensuring it remains flush with the first housing's surface, eliminating the level difference and providing a flat support for the flexible display screen, while a winding component and sensor assist in storing and retrieving the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the second housing slides out of the first housing to expand the display area, then the display screen size is increased, but a level difference is created between the first and second housing surfaces causing mold marks and uneven support
Solution Approach 1:
An elastic assembly acts as an intermediary between the first and second housings. When the second housing slides out, the elastic assembly compresses and provides a restoring force that pushes the second housing's lateral surface against the first housing's lateral surface, eliminating the level difference and preventing mold marks on the flexible display screen.
Solution Approach 2:
The elastic assembly is pre-configured to provide cushioning force before the second housing fully slides out. This beforehand cushioning ensures that the lateral surfaces remain flush throughout the expansion process, preventing uneven support and potential damage to the flexible display screen from the outset.
2Device complexity
If the second housing slides out without elastic support, then the structure is simpler, but the flexible display screen experiences weak support and potential damage
Solution Approach 1:
The elastic assembly is installed in advance within the housing structure to provide pre-configured support. When the second housing slides out, the elastic assembly immediately engages to provide upward support force, preventing the flexible display screen from sagging or experiencing weak support, thereby enhancing reliability without significantly complicating the overall structure.
3Ease of operation
If the second housing is allowed to move freely during sliding, then the operation is easier, but the lateral surfaces cannot remain flush causing screen deformation
Solution Approach 1:
The elastic assembly serves as a mediator that automatically maintains the flush relationship between lateral surfaces during sliding operation. It provides continuous elastic force to keep the second housing's lateral surface aligned with the first housing's lateral surface, ensuring screen flatness without requiring complex mechanical constraints that would hinder ease of operation.

Function Achieved in This Case
This configuration prevents mold marks, ensures a flat support surface, and enhances the touch effectiveness of the display by maintaining the screen's flatness and reducing wear during expansion and contraction.
Implementation Method 1
at least one elastic assembly configured to provide an elastic force to the second housing when the second housing slides out of the cavity of the first housing
