Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If antenna direction is adjusted manually to compensate for atmospheric changes, then propagation loss can be reduced, but the effort and time required increases significantly
Solution Approach 1:
The patent replaces manual mechanical adjustment of antenna direction with an automated calculation system that uses machine learning models and weather data to determine optimal directions, eliminating the need for physical intervention while maintaining low propagation loss
Solution Approach 2:
The system enables self-service by automatically calculating and providing optimal antenna directions based on weather conditions without requiring operator intervention, allowing the communication system to adapt autonomously to atmospheric changes
2Loss of energy
If sequential adjustment of antenna direction is performed to maintain optimal propagation, then propagation loss is minimized, but the time and complexity of operation increases
Solution Approach 1:
The system performs preliminary action by pre-calculating optimal antenna directions based on weather forecasts and atmospheric conditions before they actually affect propagation, allowing operators to prepare in advance rather than reacting sequentially to changes
Solution Approach 2:
The patent replaces time-consuming sequential manual adjustments with instant automated calculations that provide optimal directions based on real-time weather data, dramatically reducing the time required to adapt to propagation conditions
3Reliability
If large diameter antennas with high-output power amplifiers are used for OH communication, then communication reliability is improved, but device complexity and cost increase
Solution Approach 1:
The patent changes the parameter being controlled from physical antenna characteristics (size, power output) to operational parameters (direction, orientation), allowing optimization of communication reliability through intelligent direction calculation rather than through large hardware configurations

AI summary
An antenna direction calculation device acquires a plurality of relationships, each indicating a relationship between: weather data on a radio wave communication path between a transmitting-side antenna and a receiving-side antenna; and an optimal reception direction for the receiving-side antenna in a case of: a radio wave transmission direction of the transmitting-side antenna being a predetermined transmission direction; and the weather data. The antenna direction calculation device generates, using the plurality of relationships and a machine learning technique, a direction calculation model that, upon receiving an input of weather data on the radio wave communication path, outputs a reception direction for the receiving-side antenna, using the plurality of relationships and a machine learning technique.
