Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flexible flat panel devices face challenges in smoothly transitioning between flat and bent states without incurring damage, as existing technologies do not effectively manage the bending transformation, leading to potential rigidity and instability.
Innovation Solution
A flexible display device design featuring a housing with a central plate and wing plates, a supporting plate that allows for elastic deformation or shape memory alloy properties, and a locking mechanism with protrusions and springs to stabilize the panel in both states, ensuring smooth bending and flattening operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the housing structure is made rigid to maintain structural stability, then structural stability is improved, but the ability to smoothly transition between flat and bent states deteriorates
Solution Approach 1:
The housing is divided into a central plate and two wing plates that can move independently relative to each other. The wing plates are separable from the central plate, allowing one part to remain stable while the other adapts to bending states, resolving the contradiction between structural stability and bending capability.
Solution Approach 2:
The housing structure transitions from a static rigid design to a dynamic configuration where wing plates can be selectively separated or connected to the central plate. This dynamic adaptability allows the structure to maintain stability when connected and enable bending when separated, resolving the contradiction between rigidity and flexibility.
2Stability of the object's composition
If the supporting plate is firmly fixed to the housing to prevent movement, then positional stability is improved, but the smoothness of bending transformation deteriorates
Solution Approach 1:
The supporting plate is divided into multiple regions with different fixation states. Some portions are firmly fixed to provide positional stability, while other portions remain unfixed or separable to enable smooth bending transformation, resolving the contradiction between stability and smoothness.
3Stability of the object's composition
If the wing plates are permanently connected to the central plate to maintain housing integrity, then housing integrity is improved, but the versatility of display configurations deteriorates
Solution Approach 1:
The connection between wing plates and central plate is made dynamic rather than permanent. The wing plates can be connected to maintain housing integrity for flat displays, or separated to enable bent or folded configurations, resolving the contradiction between integrity and versatility.
