Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple light sources are used to obtain various information on the same target, then the information completeness is improved, but the device complexity and alignment difficulty increase
Solution Approach 1:
The patent combines multiple light sources (first light source and second light source) into a single integrated device body, with both light sources and the imaging element arranged on the same optical axis. This merging approach allows simultaneous acquisition of multiple types of information (color image, infrared image, spectral information) while reducing alignment complexity compared to separate devices.
Solution Approach 2:
The imaging device is designed with multi-functionality by integrating multiple light sources that emit different wavelengths (visible light and infrared light) within a single device. This universal design enables the device to perform multiple imaging functions simultaneously, obtaining various information on the target without requiring separate specialized devices.
2Measurement precision
If multiple light sources are focused to one focal point, then the imaging quality is improved, but the manufacturing precision requirement increases
Solution Approach 1:
The patent addresses the focal point alignment challenge by arranging multiple light sources and the imaging element on the same optical axis in a one-dimensional linear arrangement. This dimensional simplification reduces the alignment complexity from two-dimensional or three-dimensional positioning to one-dimensional axial alignment, thereby reducing manufacturing precision requirements while maintaining imaging quality.
3Loss of information
If various types of sensors are provided to diagnose and analyze target characteristics, then the diagnostic capability is improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple types of sensors (color imaging element for visible light, infrared imaging element for infrared light, and spectral imaging element for spectral analysis) into a single integrated device body. This combination enables comprehensive diagnostic capability for analyzing target characteristics while managing sensor integration within a unified structural framework.
Solution Approach 2:
The device achieves universal diagnostic capability by integrating sensors that respond to different wavelengths and types of light (visible, infrared, spectral). This multi-functional sensor array enables the single device to perform various diagnostic functions including color imaging, thermal imaging, and spectral analysis without requiring multiple separate specialized devices.
4Ease of operation
If the device is made portable for unrestricted use, then the ease of operation is improved, but the device complexity and measurement precision may deteriorate
Solution Approach 1:
The patent combines multiple imaging functions and sensors into a compact integrated device body that can be portably held and operated. By merging color imaging, infrared imaging, and spectral imaging capabilities into a single handheld unit, the device achieves portability while maintaining measurement precision through the coordinated arrangement of light sources and sensors on a common optical axis.
