Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rigid display panel structure is used, then structural stability is maintained, but the ability to change curvature is lost
Solution Approach 1:
The inner plate is segmented into multiple sections by cutting lines that extend from one surface to the other, creating independent segments that can move relative to each other. This segmentation allows the display panel to change curvature while maintaining structural stability through the distributed nature of the segments.
Solution Approach 2:
The display panel structure transitions from a static rigid configuration to a dynamic system where the inner plate segments can change their relative positions. The cutting lines enable the segments to rotate or shift, allowing the panel to adapt its curvature dynamically while the overall structure remains stable through controlled movement.
2Adaptability or versatility
If the inner plate is made completely flexible, then curvature adjustment is enabled, but structural strength is reduced
Solution Approach 1:
The inner plate has non-uniform properties due to the cutting lines, which create localized flexible regions while maintaining stronger intact regions. The cutting lines are strategically positioned to provide flexibility where needed while preserving structural strength in other areas, achieving a balance between flexibility and strength through spatially varying properties.
3Manufacturing precision
If cutting lines are added to the inner plate, then curvature control is improved, but manufacturing complexity increases
Solution Approach 1:
The cutting lines divide the inner plate into manageable segments that can be manufactured separately or as a single piece with predefined weak points. This segmentation simplifies the manufacturing process by allowing modular assembly or straightforward cutting operations, while the segmented structure provides precise curvature control through the articulated segments.
