Foldable Display Support Plates Prevent Level Differences
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible displays in portable information devices are vulnerable to impact and require stable support when folded, as existing support members can cause level differences leading to product defects.
Innovation Solution
A portable information device with foldable chassis members and support plates featuring engagement pieces that balance each other when the device is opened or closed, preventing level differences and ensuring stable display support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a support member is provided to support the flexible display on the inner surface side of the chassis member, then the display can be stably supported, but level differences may be generated in the folded portion causing display curvature
Solution Approach 1:
The support member is divided into multiple support plates (first support plate and second support plate) that can move relative to each other. Each support plate is independently controllable, allowing them to maintain contact with the display while accommodating folding movements without generating level differences that would cause display curvature.
Solution Approach 2:
The support plates are designed to be movable rather than fixed, allowing them to dynamically adjust their positions during the folding and unfolding of the chassis. This dynamic capability enables the support plates to maintain optimal contact with the display throughout the folding range, preventing display curvature while ensuring stable support.
2Adaptability or versatility
If the chassis members are made foldable for compact carrying, then portability is improved, but the flexible display becomes vulnerable to impact and curvature
Solution Approach 1:
The movable support plates are positioned to contact the flexible display before folding operations begin, providing protective support during the entire folding and unfolding process. This beforehand cushioning prevents impact damage and curvature by ensuring the display is supported throughout the motion range.
Solution Approach 2:
The support plates act as intermediary elements between the folding chassis structure and the flexible display. They absorb and distribute mechanical stresses from folding operations, protecting the display from direct impact while enabling the foldable chassis configuration for portability.
3Adaptability or versatility
If the support member is made movable to accommodate folding, then foldability is achieved, but level differences are generated causing product defects
Solution Approach 1:
The support structure is segmented into multiple independent support plates that can move relative to each other. This segmentation allows each plate to independently accommodate folding movements while maintaining contact with the display, preventing level differences that would cause display curvature.
Solution Approach 2:
The support plates are designed with feedback mechanisms that detect their relative positions and movements during folding. This feedback enables automatic adjustment of the support plates to maintain optimal contact with the display, ensuring display flatness is preserved throughout the folding operation.

AI summary
A portable information device is capable of stably supporting a foldable display. The portable information device has a first engagement piece which is provided in a first support plate, projects from the inner end surface side of the first support plate, and contacts/separates from a second support plate when a first chassis member and a second chassis member are opened/closed, and a second engagement piece which is provided in the second support plate, projects from the inner end surface side of the second support plate, and contacts/separates from the first support plate when the first chassis member and the second chassis member are opened/closed.
