Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If nanosatellite systems use outdated systems without update capability, then device complexity is reduced, but reliability deteriorates as systems cannot be updated or recovered from radiation damage
Solution Approach 1:
The platform is divided into modular functional units (power supply module, communication module, attitude determination and control module, on-board computer) that can be independently updated and maintained. Each module can be individually replaced or updated without affecting the entire system, enabling reliability improvements while managing complexity through standardized interfaces and communication buses.
Solution Approach 2:
The system incorporates redundant circuits and memory restoration capabilities in advance, allowing the microcontroller to automatically recover from radiation-induced memory errors without ground intervention. The redundant circuit is pre-configured to detect and correct memory errors, and the system includes pre-loaded backup data that can be restored when radiation damage occurs.
2Reliability
If nanosatellites lack unified communication structure, then device complexity is reduced, but reliability deteriorates as systems cannot operate with resource loss
Solution Approach 1:
The communication buses are designed with universal interfaces that can handle multiple communication protocols and data types. The same communication infrastructure supports telemetry, telecommand, payload data, and housekeeping functions, allowing the system to maintain operational reliability through a unified, multi-functional communication structure that can adapt to different operational requirements.
3Adaptability or versatility
If nanosatellites use non-expandable power supply, then device complexity is reduced, but adaptability deteriorates as solar panels cannot be expanded
Solution Approach 1:
The power supply system is designed with dynamic expandability, allowing solar panels to be added or reconfigured based on mission requirements. The power supply module includes adjustable voltage regulation and distribution systems that can accommodate varying power inputs from different solar panel configurations, enabling the platform to adapt to different orbital conditions and mission durations.
