Flexible-Rigid Cover Member for Multi-Orientation Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices lack a cover member that provides both rigidity for protection against external impacts and flexibility to accommodate various display orientations, which limits their reliability and durability.
Innovation Solution
A display device with a cover member comprising a combination of a rigid member and a flexible member, where the flexible member is formed with a bent structure and includes a polymer material, and the rigid member is partially overlapping the flexible member, allowing for the display of images in multiple directions while maintaining structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid cover member is used to protect against external impacts, then protection capability is improved, but flexibility to accommodate various display orientations deteriorates
Solution Approach 1:
The cover member is divided into multiple rigid members (first rigid member, second rigid member, third rigid member) positioned at different locations. Each rigid member provides localized protection while the distributed arrangement allows overall flexibility for various display orientations.
Solution Approach 2:
The cover member combines multiple rigid members with different orientations and positions to create a composite structure that provides both protection and adaptability. The rigid members are arranged at specific angles (e.g., 45 degrees) to achieve both strength and flexibility.
2Adaptability or versatility
If a flexible cover member is used to accommodate various display orientations, then adaptability is improved, but protection against external impacts deteriorates
Solution Approach 1:
The flexible cover member is segmented into multiple rigid members positioned at different locations and orientations. This segmentation allows the structure to be flexible enough for various orientations while maintaining protection capability through the distributed rigid elements.
Solution Approach 2:
Different regions of the cover member have different properties - some areas have rigid members for protection while other areas maintain flexibility. The rigid members are strategically positioned to provide local protection where needed while allowing overall adaptability.
3Strength
If multiple rigid members are added to the cover member, then protection capability is improved, but device complexity increases
Solution Approach 1:
The cover member is segmented into three rigid members (first, second, and third rigid members) positioned at different locations and orientations. This segmentation provides enhanced protection while maintaining manageable complexity through a systematic arrangement.
Solution Approach 2:
The multiple rigid members serve multiple functions simultaneously - they provide protection against impacts, enable various display orientations, and contribute to the overall structural integrity. This multi-functionality reduces the need for additional separate components.

AI summary
A display device includes a display member configured to display an image in a first direction and a cover member on the display member. The cover member includes a flexible member including a front part defining a front plane perpendicular to the first direction, and a first side part connected to a first side of the front part and defining a first side plane different from the front plane, and a rigid member partially overlapping the flexible member and on the front part.
