Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If millimeter wave frequency band is used for high-speed data transmission, then transmission speed is improved, but signal coverage is reduced due to weak diffraction capability
Solution Approach 1:
The patent introduces a relay node as an intermediary between the first device and second device. The relay node receives beams from the second device and transmits them to the first device, enabling communication when direct line-of-sight is blocked. This mediator approach allows millimeter wave signals to overcome obstacles while maintaining high transmission speed.
Solution Approach 2:
The patent employs beamforming technology that directs signals in specific spatial dimensions rather than omnidirectional transmission. By concentrating energy into focused beams through analog and hybrid beamforming, the system achieves both directional precision and penetration capability through obstacles, resolving the contradiction between transmission speed and coverage reliability.
2Reliability
If beamforming technology is used to improve signal coverage, then signal strength is improved, but ability to navigate obstacles is reduced due to weak diffraction
Solution Approach 1:
The relay node acts as a mediator that receives focused beams from the second device and retransmits them to the first device through or around obstacles. This intermediary approach allows the system to maintain strong signal strength via beamforming while navigating obstacles that would otherwise block direct beam transmission.
Solution Approach 2:
The system dynamically adjusts beam directions and relay node selections based on real-time channel conditions. When obstacles block direct beams, the system can switch to alternative beams or activate relay nodes, providing adaptability while maintaining strong signal strength through optimized beamforming.
3Device complexity
If direct beam transmission is used for communication, then transmission simplicity is improved, but communication reliability is reduced when obstacles block the beam path
Solution Approach 1:
The relay node introduces a simple intermediary structure that enhances reliability without significantly complicating the overall transmission architecture. The relay operates with straightforward receive-and-transmit functionality, maintaining simplicity while enabling reliable communication through obstacles.
Solution Approach 2:
The system performs preliminary beam measurement and selection before actual data transmission. By pre-measuring beam qualities and identifying optimal paths, the system ensures reliable communication is established in advance, reducing the complexity of real-time obstacle navigation and maintaining transmission simplicity.
