Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a compound-eye camera module uses multiple monocular camera modules with fixed wavelength filters, then the device can capture multiple wavelength bands simultaneously, but the image quality and detection accuracy are limited due to fixed filtering capabilities
Solution Approach 1:
The patent applies a variable wavelength filter (such as a tunable filter or spectral imager) in one of the monocular camera modules, allowing the wavelength band to be dynamically adjusted. This dynamic capability enables the system to adapt to different detection requirements and improve detection accuracy by selecting optimal wavelength bands for specific targets or conditions.
Solution Approach 2:
The patent changes the wavelength band parameter by using a variable wavelength filter that can tune its transmission characteristics. This parameter change allows the imaging system to optimize its performance for different detection tasks, thereby improving detection accuracy while maintaining the compound-eye architecture's multi-wavelength capability.
2Measurement precision
If a compound-eye camera module uses multiple monocular camera modules with different fixed filters, then color information can be captured, but image quality deteriorates due to color filter limitations and processing difficulties
Solution Approach 1:
The patent replaces fixed color filters with a variable wavelength filter that can dynamically adjust its transmission characteristics. This dynamic approach allows for more precise color reproduction by selecting optimal wavelength bands for color differentiation, while reducing processing complexity compared to traditional multi-filter compound-eye systems.
Solution Approach 2:
The variable wavelength filter serves multiple functions: it can capture color information, adjust wavelength bands for different detection tasks, and optimize image quality. This multi-functionality reduces the need for separate fixed filters for different purposes, thereby simplifying the overall system while improving color reproduction accuracy.
3Adaptability or versatility
If a compound-eye camera module uses a variable wavelength filter, then wavelength band flexibility improves, but device complexity increases
Solution Approach 1:
The patent maintains the compound-eye architecture with multiple monocular camera modules, where one module uses a variable wavelength filter. This segmentation allows the system to achieve wavelength band flexibility in a controlled manner, with the variable filter providing adaptability while the other fixed-filter modules maintaining system simplicity and providing reference data.
