Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current flexible display technologies do not offer a seamless folding and sliding mechanism that enhances user convenience and portability while maintaining durability and image display quality.
Innovation Solution
A flexible display apparatus comprising a flexible display module with a supporting member, including a hinge and guide members, that allows for folding and sliding operations by using housings and guide members to manage the display parts' exposure and accommodation, enabling both folding and sliding in multiple directions and modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display module is made flexible and foldable, then portability and versatility are improved, but durability and screen protection become problematic
Solution Approach 1:
The display module is divided into multiple flexible display parts (first, second, and third display parts) that can be independently folded and positioned. This segmentation allows the display to be folded into different configurations (flat, angled, or rolled) while protecting each segment, thereby improving portability without compromising overall durability.
Solution Approach 2:
The second and third display parts are accommodated within the first and second housings respectively when not in use. The housings act as protective containers that nest the flexible display parts, preventing damage during transport while allowing full deployment when needed. This nesting mechanism resolves the contradiction between foldability and protection.
2Adaptability or versatility
If the display parts are accommodated in housings, then protection and portability are improved, but device complexity increases
Solution Approach 1:
The housings serve multiple functions: they protect the flexible display parts during transport, guide their insertion and withdrawal movements, support the display parts in different operational configurations, and provide structural framework for the entire device. This multi-functionality reduces the need for separate protective components, thereby managing complexity while enabling versatile operation.
Solution Approach 2:
Guide members are introduced as intermediary components between the housings and the flexible display parts. These guide members facilitate smooth insertion and withdrawal movements, ensure proper positioning, and reduce friction and wear. By mediating the interaction between rigid housings and flexible display parts, the system achieves complex operational modes without proportionally increasing overall device complexity.
3Ease of operation
If guide members are used to manage display part movement, then operational smoothness is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The guide members are designed as flexible or thin-walled structures that can easily conform to the movement paths of the flexible display parts. This design allows for simple manufacturing processes such as injection molding or bending, while still providing effective guidance and smooth operation. The flexible nature of the guide members reduces manufacturing complexity compared to rigid precision-guided systems.
