Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid capping member is used to protect the flexible display panel, then protection strength is improved, but flexibility and bendability deteriorate
Solution Approach 1:
The capping member is designed with a flexible shell structure that includes bendable side walls and a bottom wall with through holes. This flexible shell can bend together with the flexible display panel during folding operations, providing continuous protection while maintaining the required flexibility and adaptability to the panel's movement.
Solution Approach 2:
The capping member incorporates dynamic elements including through holes in the bottom wall that allow deformation during bending, and bendable side walls that can dynamically adjust their shape. This dynamic structure enables the capping member to transition between protected and flexible states as needed during device operation.
2Strength
If the capping member is made completely solid without holes, then structural strength is improved, but stress relief during bending deteriorates
Solution Approach 1:
The bottom wall of the capping member is designed with multiple through holes, creating a porous structure that allows stress to be relieved during bending operations. These holes enable the structure to deform more easily without accumulating excessive stress, while the overall framework maintains sufficient structural strength for protection.
Solution Approach 2:
The bottom wall is segmented into multiple sections separated by through holes, allowing different parts of the structure to deform independently during bending. This segmentation distributes stress across multiple zones rather than concentrating it in a single solid structure, improving reliability during flexing operations.
3Stability of the object's composition
If the side walls are made rigid to provide stable support, then support stability is improved, but bendability during folding deteriorates
Solution Approach 1:
The side walls are constructed as flexible shells that can bend while maintaining their structural integrity and protective function. This flexible shell design allows the side walls to adapt to the folding motion of the display panel while continuing to provide stable support and protection during both folded and unfolded states.
Solution Approach 2:
The side walls incorporate dynamic bending capabilities with defined bend lines that allow controlled deformation. During folding, the side walls dynamically adjust their configuration while maintaining stable support of the display panel, transitioning smoothly between different operational states without compromising structural stability.
