Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If real-time high-accuracy orbital information is shared between mega-constellation business devices, then collision avoidance capability is improved, but device complexity and information management burden increase
Solution Approach 1:
The patent introduces a communication line as an intermediary component that connects mega-constellation business devices, enabling them to share real-time high-accuracy orbital information. This intermediary infrastructure resolves the contradiction by providing a dedicated channel for information exchange, improving collision avoidance capability while containing the complexity within a standardized communication framework rather than requiring each device to independently manage all orbital data.
Solution Approach 2:
The communication line serves multiple functions: it transmits orbital information, enables collision avoidance operations, and supports coordination between different mega-constellation business devices. By making the communication infrastructure multi-functional, the patent improves collision avoidance capability without proportionally increasing device complexity, as the same communication channel handles multiple operational requirements.
2Productivity
If debris removal operations are conducted in satellite groups, then debris removal efficiency is improved, but risk of collision with mega-constellation satellites increases
Solution Approach 1:
The patent implements a feedback mechanism where real-time orbital information from mega-constellation business devices is continuously shared with debris removal business devices. This feedback loop enables the debris removal operations to adjust their trajectories and operations based on current satellite positions, improving debris removal efficiency while simultaneously reducing collision risk through continuous information exchange and adaptive response.
Solution Approach 2:
The system performs preliminary actions by acquiring and processing real-time orbital information before debris removal operations commence. The communication line enables preliminary information exchange between mega-constellation and debris removal business devices, allowing collision risk assessment and avoidance maneuvers to be planned in advance, thereby improving operational efficiency while mitigating harmful collision risks.

AI summary
In a space traffic management system (500), space traffic management devices (100) individually mounted in a plurality of mega-constellation business devices and in a debris removal business device (45) are connected to each other via a communication line (200). The debris removal device (45) performs Active Debris Removal (ADR) against debris formed by a satellite managed by a first mega-constellation business operator. The debris removal device (45) acquires real-time high-accuracy orbital information of a satellite group of a second mega-constellation business operator in a timeframe in which a debris removal satellite, during orbital descent, passes through an orbital altitude region where the satellite group of the second mega-constellation flies, the debris removal satellite passing through the satellite group while ensuring flight safety.
