Engineering Contradiction Analysis
1Adaptability or versatility
If additional electronic devices are installed for 5G communication, then 5G communication functionality is improved, but noise interference increases and operation smoothness deteriorates
Solution Approach 1:
A transmissive body with a specific conductive pattern is introduced as an intermediary component between the 5G communication devices and the external environment. This transmissive body selectively transmits 5G frequency bands while blocking noise interference, acting as a mediator that allows desired signals to pass while filtering out harmful noise.
Solution Approach 2:
The transmissive body incorporates a conductive pattern with specific local properties that are optimized for different frequency ranges. The conductive material is arranged in a grid pattern with specific cell sizes and spacing that create frequency-selective transmission characteristics, allowing 5G bands to pass while blocking other frequencies.
2Object-affected harmful factors
If a transmissive body with conductive pattern is used to block noise, then noise interference is reduced, but signal transmission efficiency may deteriorate
Solution Approach 1:
The conductive pattern is segmented into a grid of virtual cells with specific dimensions and spacing. This segmentation creates multiple small conductive elements that collectively form a noise-blocking structure while maintaining openings that allow 5G signals to pass through. The segmented structure provides frequency selectivity without completely blocking the signal path.
Solution Approach 2:
The transmissive body utilizes a two-dimensional conductive grid pattern on a planar surface to achieve three-dimensional electromagnetic wave filtering. By arranging conductive material in a specific 2D pattern, the invention creates frequency-selective properties that affect 3D propagating electromagnetic waves, allowing certain frequencies to pass while blocking others.
3Reliability
If conductive material is provided in virtual grid cells, then 5G band transmittance is improved, but manufacturing complexity increases
Solution Approach 1:
The conductive pattern is created by copying the grid cell design across the entire transmissive body surface. Each virtual cell is an identical or systematically varied copy of a basic unit, which simplifies the manufacturing process by allowing standardized production techniques to be applied repeatedly across the surface.
Solution Approach 2:
The invention optimizes specific parameters of the grid cells (such as cell size, spacing, and conductive material thickness) to achieve the desired 5G band transmittance. By systematically adjusting these parameters, the invention balances performance requirements with manufacturing feasibility, avoiding overly complex structures.
