Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display modules in slidable display apparatuses are prone to deformation and defects at bent portions due to tension or compression, leading to potential damage.
Innovation Solution
Incorporation of moving bars, sliding portions, and side guide portions with bearings and accommodation holes to facilitate smooth sliding and bending of the display module, along with a central guide portion and push bars to manage curvature and rotation, ensuring minimal deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the display module is bent to allow slidable configuration, then the display apparatus can be compactly arranged, but the display module may be deformed at bent portions due to tension or compression
Solution Approach 1:
A guide portion is introduced as an intermediary component between the display module and the housing. This guide portion includes a guide surface that contacts the display module and guides its sliding movement, while a push bar applies controlled force to maintain proper curvature. The intermediary structure distributes mechanical stresses and prevents direct harmful contact between the bent display module and rigid housing structures.
Solution Approach 2:
The curvature radius of the guide surface is specifically designed to match the bending radius of the display module. By controlling the geometric parameters of the guide portion to correspond with the display module's bending characteristics, the system enables smooth sliding motion while maintaining appropriate tension and compression forces that prevent deformation and defects.
2Volume of moving object
If the display module slides along a curved path, then the apparatus achieves compact configuration, but friction and deformation increase at the bent portion
Solution Approach 1:
The guide portion is designed with a curved guide surface that matches the bending radius of the display module. This curvature alignment ensures that the display module slides along a path that maintains its natural bent shape, reducing friction and preventing deformation. The cylindrical push bar also maintains consistent curvature contact points throughout the sliding motion.
Solution Approach 2:
The guide surface acts as an intermediary between the rigid housing and the flexible display module, providing a controlled curved path that reduces friction. The push bar serves as another intermediary that applies distributed force to maintain proper curvature without creating localized stress points that would increase deformation.
