Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate noise-blocking components are added to prevent interference, then noise protection is improved, but device thickness increases
Solution Approach 1:
The noise-blocking function is merged with the antenna structure by designing the conductive sheet layer to serve both as electromagnetic shielding and as the radiator element, eliminating the need for separate noise-blocking components and maintaining thin device profile
Solution Approach 2:
The conductive sheet layer is designed with multi-functionality to simultaneously provide electromagnetic shielding against noise and serve as an antenna radiator, thereby achieving noise protection without adding extra components that would increase device thickness
2Device complexity
If the distance between components is decreased to improve integration, then device compactness is improved, but noise interference between components increases
Solution Approach 1:
The conductive sheet layer acts as an intermediary element between the display and other components, providing electromagnetic shielding that prevents noise interference while allowing close integration of components. The slit pattern in the conductive sheet allows signal transmission while maintaining shielding effectiveness
