Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If FTS uses optical interferometer to transform light into electric signals, then measurement capability is achieved, but device complexity increases and light quantity control becomes difficult
Solution Approach 1:
The patent extracts and removes the optical interferometer component from the FTS system, replacing it with a direct photoelectric transformation approach using a photodetector. This eliminates the complex interference pattern generation and Fourier transform processes, directly converting incident light into electric signals for spectral analysis.
Solution Approach 2:
The patent replaces the mechanical/optical interferometer system with an electronic photoelectric detection system. Instead of using mechanical mirror movements and optical interference, the system directly detects light intensity at different wavelengths using a photodetector, substituting complex mechanical-optical processes with a simpler electronic detection mechanism.
2Ease of operation
If FTS receives sunlight directly without light quantity adjustment, then observation simplicity is maintained, but measurement reliability deteriorates due to variable light quantity
Solution Approach 1:
The patent introduces a dynamic light quantity adjustment mechanism that automatically adapts to varying sunlight conditions. The system dynamically controls the amount of light reaching the photodetector based on real-time atmospheric conditions, ensuring optimal and consistent measurement quality without manual intervention or complex operational procedures.
3Device complexity
If FTS uses fixed opening for light reception, then device simplicity is maintained, but noise from diffused light increases
Solution Approach 1:
The patent replaces the fixed opening with a dynamic aperture control mechanism that adjusts the size and shape of the light-receiving opening based on atmospheric conditions. This dynamic adjustment allows the system to optimize the balance between capturing sufficient signal light and excluding diffused noise light, improving signal-to-noise ratio without requiring overly complex structural designs.
