Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conductive film with shielding function is used, then electromagnetic shielding capability is improved, but light interference increases and vision clarity deteriorates
Solution Approach 1:
The conductive grid is segmented into multiple isolated circular lattices distributed across the transparent supporting layer. These circular conductive elements are separated by transparent spaces, allowing light to pass through while the collective arrangement provides electromagnetic shielding. The segmentation reduces continuous light blocking while maintaining shielding effectiveness through distributed conductive paths.
Solution Approach 2:
The conductive material is locally concentrated in circular lattice patterns rather than forming continuous grids. This local quality approach places conductive properties only where needed for shielding, while leaving large transparent areas between the circles for light transmission. The circular shape with smooth edges minimizes light scattering compared to sharp-cornered grid patterns.
2Reliability
If a conductive grid is used for electromagnetic shielding, then shielding function is improved, but visual clarity is reduced due to light interference
Solution Approach 1:
The conductive grid employs circular lattices with curved boundaries instead of straight lines and sharp angles. This spheroidality principle creates smooth edges that reduce light diffraction and scattering effects. The circular shape presents a softer visual pattern that interferes less with vision clarity while maintaining the conductive properties needed for electromagnetic shielding.
3Reliability
If conductive material is filled in grooves to form a grid, then electrical conductivity is improved, but light interference increases
Solution Approach 1:
The conductive material is segmented into discrete circular lattices rather than forming continuous conductive paths. This segmentation allows electrical conductivity through the distributed circular elements while creating transparent spaces between them for light transmission. The grooves are similarly segmented into circular patterns, reducing light interference while maintaining conductive functionality.
Solution Approach 2:
The conductive grid structure creates a porous-like pattern with transparent spaces between the circular conductive lattices. This porous arrangement allows light to pass through the structure while the distributed conductive elements maintain electrical conductivity. The circular porous pattern interferes less with vision compared to solid continuous conductive grids.

AI summary
A conductive film includes a transparent supporting layer and a conductive grid. The transparent supporting layer includes a first side face and a second side face arranged opposite to each other, and the first side face is provided with grooves. A conductive material is filled in the grooves to form the conductive grid interconnected, and the conductive grid includes a plurality of circle lattices. Since the conductive material is filled in the grooves to form the conductive grid and the conductive grid includes a plurality of circle lattices, the dot pattern presented is relatively soft, and the impact on vision caused by interference is reduced.
