Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If orbital maneuvers are performed to avoid space debris, then collision risk is reduced, but fuel consumption increases and orbital position stability deteriorates
Solution Approach 1:
The system performs preliminary detection of space debris orbital elements and predicts potential collision courses before they materialize. By identifying risks in advance and executing preventive orbital maneuvers only when necessary, the system avoids continuous fuel-consuming adjustments while maintaining collision avoidance reliability
Solution Approach 2:
The system dynamically adjusts orbital parameters (such as right ascension of ascending node and inclination) based on detected debris characteristics and predicted close approaches. By making targeted, parameter-specific adjustments rather than continuous full-orbit corrections, fuel consumption is minimized while maintaining safety
2Reliability
If continuous orbital monitoring and maneuvers are performed, then collision avoidance capability is improved, but system complexity and operational difficulty increase
Solution Approach 1:
The satellite control unit integrates multiple functions into a single system: it detects debris orbital elements, predicts close approaches, determines optimal maneuver parameters, and executes control commands. This multi-functional integration reduces overall system complexity while maintaining comprehensive collision avoidance capability
Solution Approach 2:
The system autonomously detects space debris, predicts collision risks, and executes orbital maneuvers without requiring continuous external intervention. The self-service capability reduces operational complexity while maintaining high reliability in collision avoidance
3Stability of the object's composition
If the satellite maintains a fixed geostationary position, then communication service stability is improved, but vulnerability to space debris collision increases
Solution Approach 1:
The system transitions from a static geostationary position to a dynamically adjustable orbit when debris threats are detected. By enabling controlled deviations from the nominal geostationary position only when necessary, the system maintains service stability while reducing collision vulnerability
Solution Approach 2:
The system applies preliminary counter-actions by detecting debris trajectories and executing orbital adjustments before potential collisions occur. This preliminary anti-action protects the fixed geostationary position from harmful debris while minimizing disruptions to service stability
