Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional linkage structure with fixed accommodation spaces is used, then the structure is simple and easy to manufacture, but the accommodation spaces do not match the inconsistent deformation amounts and shapes of flexible screens during folding
Solution Approach 1:
The patent applies dynamics by making the linkage structure movable and adjustable rather than fixed. The linkage includes multiple connected segments that can change relative positions and angles, allowing the accommodation space to dynamically adapt to different deformation amounts and shapes of the flexible screen during folding operations.
Solution Approach 2:
The linkage structure is divided into multiple independent segments or links connected by joints. This segmentation allows each segment to move independently, enabling the overall structure to flex and adjust to match the varying deformation characteristics of different flexible screens while maintaining structural integrity.
2Reliability
If the flexible screen is folded with fixed accommodation spaces, then the folding operation is simple, but the flexible screen may not be completely flattened when unfolded or may be damaged
Solution Approach 1:
The support structure uses dynamic linkage mechanisms that adjust in real-time during folding and unfolding operations. This ensures the accommodation spaces precisely match the flexible screen's deformation at each stage, protecting the screen from damage while ensuring complete flattening when unfolded.
Solution Approach 2:
The linkage structure incorporates feedback mechanisms where the position and deformation state of the flexible screen influence the configuration of the accommodation spaces. As the screen deforms during folding, the linkage automatically adjusts to provide appropriate support, preventing damage and ensuring proper flattening.
3Adaptability or versatility
If conventional fixed linkage structures are used, then the device structure is simple, but the sizes and angles of accommodation spaces are fixed and cannot adapt to different flexible screen deformations
Solution Approach 1:
The linkage structure is designed as a dynamic system with multiple movable joints and segments that can change configuration during folding. This allows the sizes and angles of accommodation spaces to continuously adapt to different flexible screen deformations, ensuring smooth folding operations without fixed constraints.
Solution Approach 2:
By dividing the linkage into multiple segments connected by joints, each segment can move independently to adjust the overall accommodation space configuration. This segmentation enables the structure to adapt to various deformation patterns while maintaining operational smoothness through coordinated segment movement.
