Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate computer programs are used for different parts of the simulation, then the simulation can cover various aspects of the sensing system, but the user intervention required is extensive and the processing efficiency is reduced
Solution Approach 1:
The patent combines multiple separate simulation computer programs into a single integrated simulation system. The sensing system simulator includes modules for path modeling, radiative transfer, instrument response, and data processing that all operate within one unified program, eliminating the need for users to manually coordinate multiple separate programs and thereby reducing user intervention while maintaining comprehensive simulation coverage.
Solution Approach 2:
The integrated simulation system performs multiple simulation functions within a single program, including modeling sensor paths, radiative transfer processes, instrument responses, and ground system processing. This multi-functional approach allows the system to handle various aspects of sensing system simulation without requiring separate specialized programs for each function.
2Adaptability or versatility
If multiple separate simulation programs are used, then comprehensive simulation capabilities can be achieved, but the complexity of system integration and user coordination increases
Solution Approach 1:
The patent merges multiple simulation functions into a single integrated program structure. The simulator includes interconnected modules for path modeling, radiative transfer, instrument response, and ground system processing that automatically exchange data through defined interfaces, eliminating the need for complex external coordination between separate programs and reducing overall system integration complexity.
3Ease of manufacture
If generic simulation processing is used for all data types, then the processing approach is simple to implement, but the processing efficiency for specific data types is reduced
Solution Approach 1:
The simulation system implements data type-specific processing modules within the integrated program. Different instrument response models and processing algorithms are applied based on the specific data type being simulated (e.g., different spectral response functions for different sensor types). This allows the system to maintain a simple unified structure while incorporating specialized processing optimized for each data type, thereby improving processing efficiency without sacrificing implementation simplicity.
