Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If 5G signals pass through glass and obstacles, then signal transmission is achieved, but signal attenuation increases and signal strength decreases
Solution Approach 1:
The patent introduces an optical relay device as an intermediary component installed in glass windows. This device includes light emitting units and light receiving units that convert electrical signals to optical signals and back, serving as a mediator to transmit 5G signals through glass obstacles without direct signal penetration, thereby reducing signal attenuation and maintaining signal strength.
Solution Approach 2:
The patent replaces the direct electromagnetic wave transmission mechanism with an optical signal transmission mechanism. Instead of relying on 5G radio waves to pass through glass (which causes attenuation), the system uses optical signals that can be efficiently transmitted through the optical relay device, substituting the physical transmission mechanism to overcome the attenuation problem.
2Productivity
If optical relay device uses multiple light emitters and receivers, then signal transmission rate increases, but device complexity increases
Solution Approach 1:
The optical relay device is segmented into multiple functional units: light emitting units and light receiving units. Each unit can be independently configured with multiple light emitters or receivers connected in parallel. This segmentation allows the system to achieve higher signal transmission rates by increasing the number of parallel channels while maintaining modular architecture that manages device complexity through standardized unit designs.
