Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional lighter metals like aluminum are used to construct satellite components, then the satellite structure has well understood thermal and electrical properties, but the manufacturing process requires long periods of planning, testing, and lead times
Solution Approach 1:
The satellite is divided into modular components that can be independently manufactured and tested. This segmentation allows parallel development of different modules, reducing overall lead time while maintaining reliability through standardized interfaces and proven subsystems.
Solution Approach 2:
Extensive ground testing and validation are performed on satellite components and systems before launch. This preliminary action includes thermal vacuum testing, vibration testing, and electrical characterization to ensure predictable thermal and electrical properties in orbit, reducing the need for lengthy in-orbit testing.
2Quantity of substance
If satellites capture and transmit over 10 million raw photos per day, then comprehensive data is collected, but it takes hours to process and extract analytics from the raw photos
Solution Approach 1:
Analytics extraction and processing are performed in advance on ground-based systems before data is transmitted to end users. This preliminary processing reduces latency by preparing valuable insights ahead of time, so when data is needed, pre-processed analytics are already available rather than requiring hours of processing upon request.
Solution Approach 2:
An intermediary processing system is introduced between data capture and final delivery. This intermediary layer performs initial analytics extraction, filtering, and prioritization on ground-based facilities, reducing the burden on onboard processing and enabling faster delivery of key insights to end users.
3Measurement precision
If existing light filtration technologies are used in orbital devices, then basic light filtering is achieved, but the filtration performance is limited and reliability under harsh space conditions is reduced
Solution Approach 1:
Advanced composite light filtering materials are used that combine multiple layers and properties to achieve superior filtration performance. These composite structures provide better wavelength selectivity and maintain reliability under extreme temperature fluctuations and radiation exposure by distributing stress and protecting sensitive filtering layers.
Solution Approach 2:
Protective measures are built into the light filtering system design to withstand harsh space conditions. This includes radiation-hardened materials, thermal protection layers, and redundant filtering elements that are designed beforehand to cushion against the effects of space environment, ensuring continued reliable operation.
