Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the non-terrestrial network apparatus operates continuously to provide communication services, then the traffic volume increases and service quality improves, but the remaining power amount decreases and power exhaustion risk increases
Solution Approach 1:
The patent implements dynamic control of the non-terrestrial network apparatus by adjusting its operational state based on real-time monitoring of remaining power amount and traffic volume. The control apparatus dynamically selects between different operation modes (normal operation, power-saving mode, or standby) to optimize the balance between service provision and power conservation, ensuring continuous operation while preventing power exhaustion.
Solution Approach 2:
The system employs feedback control by continuously monitoring the remaining power amount and traffic volume, then using this information to adjust operational parameters. The control apparatus receives power amount information from the non-terrestrial network apparatus and uses this feedback to determine appropriate control actions, creating a closed-loop control system that adapts to changing power and traffic conditions.
2Use of energy by moving object
If the non-terrestrial network apparatus charges the battery using solar power generation, then the remaining power amount increases, but the time available for charging is limited by the orbit and position
Solution Approach 1:
The control apparatus performs preliminary assessment of the charging situation by determining the satellite's position and orbit characteristics before initiating charging operations. It calculates expected charging duration based on orbital parameters and uses this information to plan power management strategies in advance, allowing the system to prepare for power shortages or surpluses before they occur.
Solution Approach 2:
The system changes operational parameters based on charging conditions by adjusting traffic handling policies, power consumption levels, and operation modes according to the available charging time and remaining power amount. This allows the non-terrestrial network apparatus to adapt its behavior to the constraints imposed by orbital mechanics and solar power availability.
3Reliability
If the control apparatus implements comprehensive power management based on traffic volume and remaining power amount, then the operation stability improves, but the device complexity increases
Solution Approach 1:
The control apparatus is divided into distinct functional modules: a determination unit that assesses power and traffic conditions, and a control unit that executes specific control actions. This segmentation allows the complex power management function to be broken down into manageable, independent components that can be developed, tested, and maintained separately while working together to achieve stable operation.
