Flexible Display Support Plate Structure to Prevent Lifting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with flexible displays experience lifting issues during transitions due to restoring forces, degrading surface quality and assembly characteristics.
Innovation Solution
A lifting prevention structure is implemented using a bendable member with engaging protrusions that engage with a guide slit, ensuring continuous support of the flexible display during transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a support member is provided between the bendable member and the housing to reduce lifting, then the surface quality is improved, but the assembly characteristics are degraded
Solution Approach 1:
The support member is merged with the bendable member to form an integrated structure. The support member includes a pressing part that contacts the bendable member and a guide slit that receives engaging protrusions from the bendable member, combining support functionality with guidance into a single component assembly.
Solution Approach 2:
The support member acts as an intermediary component between the bendable member and the housing. It provides continuous support to prevent lifting while the guide slit and engaging protrusions mechanism ensures proper positioning and movement guidance, mediating between the flexible display and the rigid housing structure.
2Area of moving object
If the flexible display is bent while being supported by the bendable member, then the display area is expanded, but the display is lifted by restoring force degrading surface quality
Solution Approach 1:
The support member provides preliminary support to the bendable member before the flexible display is fully deployed. The pressing part continuously contacts the bendable member to counteract restoring forces that would cause lifting, preventing surface quality degradation before it occurs during the expansion process.
Solution Approach 2:
The support member provides continuous support throughout the entire deployment process. The guide slit and engaging protrusions mechanism ensure continuous contact between the support member and bendable member, maintaining constant support force to prevent lifting while the display area expands from the retracted to the extended state.
