Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the foldable link is used to support the display panel while unwound from the roller, then the display panel can be held in a standing position, but the durability of the foldable link is inadequate due to repeated folding and unfolding
Solution Approach 1:
The module cover is divided into multiple segments that can rotate relative to each other around the roller. This segmentation allows the cover to adapt to the curved surface of the roller during winding/unwinding while maintaining structural integrity, reducing stress on individual connection points and improving overall durability.
Solution Approach 2:
The module cover transitions from a static structure to a dynamic one where segments can rotate relative to each other. This dynamic capability allows the cover to flex and adapt during the winding and unwinding process, reducing mechanical stress on the foldable link and improving its durability.
2Volume of moving object
If the display panel is wound around the roller for compact storage, then the device portability is improved, but the uniformity of winding and unwinding is poor causing mechanical stress
Solution Approach 1:
The module cover segments are designed to rotate relative to each other, creating a dynamic structure that adapts to the roller's curvature. This allows the cover to maintain uniform contact with the roller surface during winding and unwinding, distributing mechanical stress evenly and preventing deformation of the display panel.
Solution Approach 2:
The rotational angles between adjacent segments of the module cover are adjusted based on the roller's diameter and the display panel's flexibility. This parameter optimization ensures uniform winding and unwinding, minimizing mechanical stress while maintaining compact storage capability.
3Strength
If the module cover is rigid to protect the display panel, then protection is improved, but the ability to wind and unwind uniformly around the roller is reduced
Solution Approach 1:
The module cover is segmented into multiple rotatable sections, each providing local protection while allowing global adaptation to the roller's curvature. This segmentation maintains protective functionality while enabling the cover to flex and conform to the cylindrical shape during winding and unwinding operations.
Solution Approach 2:
The module cover transitions from a two-dimensional flat structure to a three-dimensional segmented structure that can rotate around the roller. This dimensional transformation allows the cover to maintain protective strength while adapting to the curved surface, enabling uniform winding and unwinding.
