Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flexible display devices struggle to maintain a bent shape without external mounts, limiting user flexibility and practicality.
Innovation Solution
A flexible display device design featuring a display panel with bending areas, a frame, guide parts, fixing parts, and a variable-length controller that allows the device to be freely bent and arched, with the fixing parts coupled to the guide parts to maintain the bent state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the flexible display device is bent without mounting structures, then the ease of operation is improved, but the stability of the bent shape deteriorates
Solution Approach 1:
The mounting structure transitions from a static fixed state to a dynamic movable state. The mounting part is configured to move along the bending axis, allowing it to adapt to different bending positions while maintaining stability. This dynamic adjustment enables the device to be bent freely without compromising the stability of the bent shape.
Solution Approach 2:
The mounting structure is divided into separate components: a mounting part and a mounting groove. The mounting part can selectively engage with the mounting groove at different positions, allowing segmented adjustment of the bending location while maintaining overall structural stability.
2Stability of the object's composition
If mounting structures are added to maintain bent shape, then the stability of bent shape is improved, but the device complexity increases
Solution Approach 1:
The mounting structure is integrated into the frame body, merging the mounting function with the existing structural component. This reduces the need for separate, complex mounting mechanisms while maintaining the stability of the bent shape.
Solution Approach 2:
The mounting part and mounting groove are designed to work together in a self-aligning manner. The mounting part automatically engages with the mounting groove at the desired bending position without requiring complex adjustment mechanisms, thereby simplifying the overall device structure.
3Manufacturing precision
If the bending position is fixed in advance, then the manufacturing precision is improved, but the adaptability deteriorates
Solution Approach 1:
The mounting structure enables dynamic repositioning of the bending location. The mounting part can be moved to different positions along the frame and selectively engaged with mounting grooves at various locations, allowing the device to adapt to different bending positions while maintaining manufacturing precision at each position.
Solution Approach 2:
The frame is designed with multiple mounting grooves at different positions, making the mounting structure universal. The same mounting part can engage with any of the mounting grooves, providing multi-functionality and adaptability for different bending configurations without requiring separate mounting mechanisms for each position.
