Flexible Support Member for Curved Display Stress Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses with curved surfaces face stress issues when attached to structures with different curvatures, leading to potential damage and visible stains from uneven force distribution.
Innovation Solution
A display apparatus design featuring a flexible support member with concave and convex portions along the curvature direction, attached to the rear surface, which disperses applied forces and prevents stains by matching the curvature of the display to the attachment structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid support structure is used to attach the curved display to a set, then the display can be securely mounted, but stress concentrates at specific points causing potential damage and visible stains
Solution Approach 1:
The support member is designed with flexible characteristics, featuring a hollow cylindrical shape with radial ribs that can elastically deform. This flexibility allows the support member to conform to the curved display surface and distribute mounting stresses uniformly, preventing stress concentration and visible stains while maintaining secure attachment.
Solution Approach 2:
The support member's structural parameters are optimized by creating a hollow cylindrical configuration with multiple radial ribs. This geometric parameter change transforms a rigid structure into a flexible one that can adapt to curvature variations, thereby distributing forces evenly across the display surface without causing localized stress damage.
2Stability of the object's composition
If the support member is made rigid to provide stable support, then structural stability is improved, but the ability to adapt to different curvature radii is reduced
Solution Approach 1:
The support member employs a flexible hollow cylindrical shell structure with radial ribs that can elastically deform. This design provides structural stability through the ribbed configuration while simultaneously enabling adaptation to different curvature radii through elastic deformation, resolving the contradiction between rigidity and flexibility.
Solution Approach 2:
The support member transitions from a static rigid structure to a dynamic flexible structure that can adapt its shape. The hollow cylindrical design with radial ribs allows the support member to dynamically adjust to various curvature radii while maintaining structural integrity, achieving both stability and adaptability.
3Ease of manufacture
If force is applied at a single point for mounting, then the attachment process is simple, but the force is not evenly distributed causing stains on the display surface
Solution Approach 1:
The support member is segmented into multiple radial ribs extending from the hollow cylinder. This segmentation divides the force application into multiple contact points along the curved surface, distributing the mounting force evenly and preventing localized stress concentration that would cause stains, while maintaining simple single-point attachment methodology.
Solution Approach 2:
The support member acts as an intermediary between the mounting structure and the curved display. Its hollow cylindrical shape with radial ribs distributes the mounting force across multiple points on the display surface, preventing direct concentrated force application and the resulting stains while keeping the mounting process simple.
