Flexible Display Support Member for Precise Foldable Module Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in assembling foldable electronic devices is the difficulty in controlling the precision of adhesive application for flexible display modules, leading to significant fitting deviations between the flexible display module and the foldable center frame.
Innovation Solution
A support member with outward protrusion portions and positioning holes is used, allowing the flexible display module to be positioned accurately on an assembly table using positioning columns, ensuring precise alignment and reducing fitting deviations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional support member without protrusion portions is used, then the structure is simple, but the positioning precision during assembly is poor
Solution Approach 1:
The support member is segmented into a body portion and multiple outward protrusion portions. Each protrusion portion extends from different sides of the body and contains positioning holes, dividing the positioning function across multiple distributed elements rather than relying on a single centralized positioning structure.
Solution Approach 2:
The outward protrusion portions act as intermediary elements that extend from the support member body to engage with positioning columns on the assembly table. These protrusions serve as mediators that transfer and precise the positioning function, enabling accurate alignment between the support member and the assembly table.
2Manufacturing precision
If multiple positioning holes with different shapes are used, then the positioning accuracy is improved, but the manufacturing complexity increases
Solution Approach 1:
Different positioning holes at different locations have different shapes (circular, elliptical, or strip-shaped) tailored to their specific positioning requirements. For example, circular holes provide omnidirectional positioning, while elliptical or strip-shaped holes provide positioning in specific directions, optimizing the positioning function at each local location.
Solution Approach 2:
The invention varies the shape parameters of positioning holes (circular, elliptical, strip-shaped) to achieve different positioning characteristics. By changing the geometric parameters of the holes, the support member can accommodate different positioning column configurations and achieve precise positioning in various directions without increasing overall structural complexity.
3Ease of operation
If protrusion portions are added to the support member, then the positioning function is enhanced, but the device complexity increases
Solution Approach 1:
The positioning function is segmented across multiple outward protrusion portions distributed at different sides of the support member. Each protrusion contains positioning holes that work together to provide comprehensive positioning, dividing the overall positioning task into multiple localized functions.
Solution Approach 2:
The outward protrusion portions serve multiple functions: they extend the support member's reach to engage with positioning columns, provide mounting locations for positioning holes, and distribute the positioning function across multiple locations. This multi-functionality enhances the positioning capability without requiring separate dedicated positioning components.

AI summary
Provided is a support member of a flexible display module. The support member includes: a body portion and a plurality of outward protrusion portions. The plurality of outward protrusion portions are at least distributed at two opposite sides of the body portion and protrude outwards relative to the sides of the body portion. A positioning hole is formed in each of the outward protrusion portions.
