Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If terahertz waves are used for wireless communication, then transmission speed and bandwidth are improved, but propagation loss and molecular absorption increase significantly
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting transmission parameters based on environmental conditions. The system monitors environmental factors (temperature, humidity, pressure) and channel measurement information to determine optimal transmission frequencies and power levels, thereby compensating for propagation loss and molecular absorption effects in terahertz bands
Solution Approach 2:
The patent implements feedback mechanisms through channel measurement information collection and environmental factor monitoring. The system continuously measures channel conditions and environmental parameters, then uses this feedback to adaptively select transmission frequencies and adjust transmission power, resolving the contradiction between high transmission speed and energy loss
2Productivity
If transmission frequency is increased in terahertz bands, then bandwidth and data rate are improved, but frequency selectivity and attenuation spectrum peaks worsen
Solution Approach 1:
The patent applies dynamics by making the transmission frequency selection adaptive rather than static. The system dynamically selects transmission frequencies based on real-time environmental conditions and channel measurements, avoiding fixed frequency assignments that would be affected by attenuation spectrum peaks and frequency selectivity issues
Solution Approach 2:
The patent changes the transmission frequency parameter based on environmental factors and channel conditions. By monitoring temperature, humidity, pressure and channel measurement information, the system selects optimal frequency resources that avoid attenuation peaks, thereby maintaining both high data rate and reliable transmission
3Productivity
If environmental factors and channel measurement information are used to determine transmission frequency, then spectrum efficiency is improved, but system complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-establishing the relationship between environmental factors and optimal transmission frequencies. The system pre-processes environmental data and channel measurement information to create lookup tables or pre-computed frequency selections, reducing the real-time computational complexity while maintaining spectrum efficiency
