Groove Patterned Folding Window for Flexible Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing flexible display devices face issues with window deformation or damage during folding operations and are prone to external impacts.
Innovation Solution
A window design with a folding part that includes groove patterns extending in one direction, arranged in a specific pattern to enhance folding characteristics and mechanical properties, allowing for improved durability and resistance to external impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the window is made rigid to resist external impacts, then mechanical strength is improved, but folding characteristics deteriorate
Solution Approach 1:
The window is divided into multiple parts: a folding part containing groove patterns that enable bending, and non-folding parts that maintain structural rigidity. This segmentation allows different regions to serve different functions - the groove-patterned folding part provides flexibility while the solid non-folding parts provide impact resistance.
Solution Approach 2:
Different regions of the window have different structural properties. The folding part has groove patterns creating localized flexibility, while the non-folding parts maintain uniform solid structure for strength. This local differentiation resolves the contradiction by providing both folding capability and impact resistance in appropriate locations.
2Ease of operation
If the window is made flexible to enable folding, then folding characteristics are improved, but mechanical strength deteriorates
Solution Approach 1:
The window structure separates flexible and rigid functions into distinct segments. The folding part with groove patterns handles the flexibility requirement, while the non-folding parts handle the strength requirement, eliminating the need to compromise either property throughout the entire window.
Solution Approach 2:
The window functions as a composite structure combining flexible groove-patterned regions with rigid non-folding regions. This composite approach allows the system to exhibit both flexible and strong characteristics simultaneously, depending on which part is engaged.
3Ease of manufacture
If the window structure is simplified, then manufacturing ease is improved, but durability against external impacts deteriorates
Solution Approach 1:
The window design segments the structure into standardized folding and non-folding parts with groove patterns. This modular segmentation simplifies manufacturing by allowing repeated production of standardized components while maintaining durability through the proven groove pattern design that has been optimized for impact resistance.

AI summary
A window includes: a folding part foldable around a virtual folding axis extending in a first direction, and first and second non-folding parts spaced apart from each other in a second direction perpendicular to the first direction with the folding part therebetween. A plurality of groove patterns extending in the first direction and arranged in the second direction are defined in the folding part. The folding part includes a first part adjacent to the folding axis, a third part adjacent to one of the first and second non-folding parts and a second part between the first part and the third part. widths of the first to third parts in the second direction are the same. A volume of the first part is greater than a volume of the second part, and the volume of the second part is greater than a volume of the third part.
