Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an electromagnetic shielding member is designed with a planar shape, then it can effectively reflect electromagnetic waves, but it cannot be applied to three-dimensional objects
Solution Approach 1:
The patent applies curvature by forming the substrate into a three-dimensional shape (such as a hemisphere or other curved geometries) rather than maintaining a flat planar structure. This allows the electromagnetic shielding member to conform to and be applied on three-dimensional objects while maintaining its electromagnetic wave reflection capability through the curved surface configuration.
2Reliability
If a conductive layer is added to reflect electromagnetic waves, then shielding performance is improved, but optical transparency is reduced
Solution Approach 1:
The patent applies local quality by creating a patterned conductive layer where conductive portions and non-conductive portions are spatially distributed. The conductive portions provide electromagnetic wave reflection at specific locations, while the non-conductive portions allow optical transmission. This local differentiation enables both shielding performance and transparency to coexist by assigning different functional qualities to different regions of the same layer.
3Reliability
If a conductive layer with patterns is used for wavelength-selective reflection, then selectivity is improved, but manufacturing complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the conductive layer into distinct conductive portions and non-conductive portions arranged in specific patterns. This segmentation allows different wavelength ranges to be selectively reflected or transmitted based on the geometric configuration and distribution of these segmented regions, achieving wavelength selectivity through spatial division rather than complex material compositions.
