Foldable Display Hinge Cover Segmentation for Easier Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flexible display devices, such as foldable and rollable displays, face challenges in repair and maintenance due to complex hinge mechanisms that are difficult to access and replace.
Innovation Solution
A display device design featuring a foldable region and non-folding regions with support parts and hinges, allowing for easy disassembly and replacement of defective hinges by separating hinge covers and coupling new hinges to support parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If complex hinge mechanisms are used to enable foldable display functionality, then the device achieves flexible deformation capability, but the repair and maintenance difficulty increases due to inaccessibility of hinge components
Solution Approach 1:
The hinge cover is divided into multiple separable parts that can be detached to expose the hinge mechanism. This segmentation allows repair personnel to access and replace defective hinge components without disassembling the entire display device, thus resolving the contradiction between maintaining flexible deformation capability and enabling easy repair access.
Solution Approach 2:
The defective hinge is extracted from the assembly by first removing the hinge cover, then separating the hinge from the support part. This extraction process enables replacement of only the defective hinge component while leaving other functional parts intact, improving repair ease without compromising the foldable functionality.
2Device complexity
If hinge mechanisms are integrated into the display module structure, then the device achieves compact design, but the time required for hinge replacement increases due to complex disassembly procedures
Solution Approach 1:
The hinge cover is segmented into removable portions that can be quickly detached to access the hinge. This segmentation reduces the number of disassembly steps required for hinge replacement, thereby reducing replacement time while maintaining the integrated structural design of the display module.
Solution Approach 2:
The hinge cover is pre-configured with removable sections that facilitate quick access to the hinge mechanism. This preliminary design consideration enables faster hinge replacement by eliminating the need for complex disassembly procedures, thus reducing the time loss associated with maintenance operations.
3Stability of the object's composition
If multiple hinges are used to support the foldable region, then the device achieves improved structural stability, but the difficulty of identifying and replacing defective hinges increases
Solution Approach 1:
The hinge cover is segmented to provide individual access to each hinge mechanism. This segmentation allows repair personnel to visually inspect and identify defective hinges among multiple hinges without disassembling the entire structure, thus maintaining structural stability while reducing the difficulty of defect detection.
Solution Approach 2:
The removable hinge cover acts as an intermediary that provides access to the hinge mechanisms. By removing this intermediary component, all hinges become visible and accessible for inspection, enabling easy identification of defective hinges while preserving the structural stability provided by the multiple hinge configuration.
