Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If prior art light filters are used in orbital devices, then light filtration function is provided, but the cost becomes prohibitively expensive and reliability is insufficient
Solution Approach 1:
The light filter system is divided into multiple independent filter devices that can be selectively positioned. Each filter device is a separate component that can be independently manufactured and tested, reducing the overall development risk and cost compared to a monolithic filter system. The filter library allows modular assembly of filters based on specific mission requirements.
Solution Approach 2:
The system employs a filter selection device that can dynamically switch between different filter devices in the filter library. This dynamic reconfigurability allows the same hardware platform to adapt to different wavelength filtering requirements without requiring multiple dedicated systems, thereby reducing development costs and improving reliability through selective component replacement.
2Adaptability or versatility
If prior art light filters are used, then filtration is provided, but configurability for desired wavelengths is insufficient
Solution Approach 1:
The filter system is segmented into multiple discrete filter devices, each optimized for specific wavelength ranges. This segmentation allows independent optimization of each filter's performance characteristics while maintaining a manageable overall system architecture. The filter library organizes these segmented filters in a structured manner that simplifies selection and configuration.
Solution Approach 2:
The filter selection device provides dynamic reconfiguration capability, allowing the system to switch between different filter devices based on the specific wavelength filtering requirements. This dynamic adaptability enables the system to handle diverse scientific instruments and observation goals without requiring custom-designed filters for each application, thereby reducing overall system complexity.
3Measurement precision
If multiple filter devices are used for different wavelengths, then wavelength selectivity is improved, but device complexity increases
Solution Approach 1:
The filter selection device serves as a universal interface that manages multiple filter devices with different wavelength characteristics. Instead of requiring separate dedicated systems for each wavelength range, the selection device provides a unified mechanism for switching between filters, thereby achieving high wavelength filtering precision while keeping the overall device complexity manageable through multi-functional integration.
