Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If space system is operated in real world with traditional simulation devices, then operation control can be performed, but comprehensive digital representation and interconnection with space events are lacking
Solution Approach 1:
The patent creates a digital twin (virtual copy) of the space system that replicates its structure, state, and behavior. This digital representation captures comprehensive information about the space system including satellite parameters, orbital data, and operational states, resolving the information loss problem while maintaining reliable operation through the virtual model
Solution Approach 2:
The digital twin serves as an intermediary between the real space system and ground control equipment. It enables comprehensive data exchange and interconnection with space events, allowing operators to interact with a complete digital representation rather than losing critical information
2Productivity
If ground equipment and simulation devices are used for space system control, then basic control functions are achieved, but optimal operation and future prediction are limited
Solution Approach 1:
The digital twin continuously receives data from the real space system and space events, processes this information, and provides feedback for optimized control decisions. This feedback loop enables efficient operation by learning from historical data and predicting future states, enhancing adaptability beyond traditional simulation devices
Solution Approach 2:
The digital twin performs preliminary simulations and predictions of future space system states based on current data and historical patterns. This allows operators to anticipate future conditions and prepare optimal control strategies in advance, improving both efficiency and adaptability
3Ease of manufacture
If traditional simulation devices are used for specific parts, then localized simulation is possible, but comprehensive interconnection with space events is not achieved
Solution Approach 1:
The patent merges the simulation of the space system with the representation of space events into a unified digital twin model. This integration achieves comprehensive interconnection where space events are naturally linked to the space system state, maintaining ease of simulation while reducing the apparent complexity through unified modeling
