Foldable Display Plate with Slit Segments for Foreign Matter Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable display modules are prone to damage from foreign matter that can accumulate on their rear surfaces when in a folded state, potentially causing damage when transitioning to a flat state.
Innovation Solution
The design incorporates a plate with slit areas on both sides of the display module, featuring extensions and slits that extend towards each other, creating a zigzag pattern to prevent foreign matter from entering the gap between the plates and reduce the likelihood of damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid plate is used to support the rear surface of the foldable display module, then structural strength is improved, but foreign matter can accumulate on the exposed rear surface in folded state causing damage
Solution Approach 1:
The plate is divided into multiple segments with slits created between them, transforming a continuous rigid structure into a segmented one. This segmentation allows the plate to maintain structural strength while creating gaps that prevent foreign matter accumulation, resolving the contradiction between strength and foreign matter protection.
Solution Approach 2:
The plate is designed with slits that create a porous structure, allowing it to remain rigid while having openings that prevent foreign matter from accumulating on the rear surface. The porous design enables the plate to fulfill both structural support and foreign matter prevention functions simultaneously.
2Adaptability or versatility
If the plate is made flexible to conform to the curved surface in folded state, then adaptability is improved, but manufacturing precision and structural integrity deteriorate
Solution Approach 1:
By segmenting the plate into multiple parts with slits, each segment can independently flex and adapt to the curved surface during folding, while the overall plate structure maintains its structural integrity. The segmentation allows local flexibility without compromising global structural strength.
Solution Approach 2:
The plate transitions from a static rigid structure to a dynamic segmented structure that can adapt its shape during folding. The slits enable the plate to dynamically adjust its configuration between flat and curved states, maintaining both adaptability and structural integrity through controlled flexibility.
