Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional objective lenses are used to achieve high resolution imaging, then imaging quality is improved, but device size and complexity increase
Solution Approach 1:
The patent divides the optical system into multiple lens arrays (first lens array for excitation light, second lens array for emission light) arranged in a segmented configuration. Each lens array performs a specific function, allowing the system to achieve high resolution imaging while maintaining a compact and less complex overall structure compared to conventional single objective lens systems.
Solution Approach 2:
The patent transitions from the conventional single optical path to a multi-dimensional optical configuration by implementing separate lens arrays for excitation and emission light paths. This dimensional separation allows independent optimization of each optical path, achieving high resolution while reducing the complexity associated with single high-performance objective lenses.
2Loss of information
If laser scanning is used to collect sufficient light data, then imaging completeness is improved, but imaging time increases
Solution Approach 1:
The patent enables continuous light collection from the entire specimen area simultaneously through the lens arrays, eliminating the need for sequential laser scanning. Multiple light detection elements collect emission light continuously across the field of view, significantly reducing imaging time while maintaining complete light data acquisition.
3Adaptability or versatility
If beam splitter is added to separate light paths, then light separation functionality is improved, but device size increases
Solution Approach 1:
Instead of using a beam splitter to separate light paths, the patent segments the optical system into distinct lens arrays for excitation and emission light. This segmentation eliminates the need for beam splitters and associated bulky components, achieving light path separation through spatial arrangement rather than optical beam manipulation.
Solution Approach 2:
The patent extracts the beam splitter component from the optical system by implementing separate, dedicated lens arrays for excitation and emission light paths. This extraction eliminates the bulky beam splitter while maintaining the essential light separation functionality through physical and optical path differentiation.
