Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If an endoscopic optical molecular imaging navigation system is used to reach deep imaging zones, then imaging depth is improved, but imaging field of view becomes small
Solution Approach 1:
The patent implements a switchable imaging system that can dynamically change between endoscopic mode (for deep imaging) and open mode (for wide field of view). The switching module allows the system to adapt its configuration based on imaging requirements, making the field of view adjustable rather than fixed, thus resolving the contradiction between depth and width.
Solution Approach 2:
The patent creates a multi-functional imaging system that can perform both endoscopic imaging (deep zones) and open imaging (wide areas) using the same apparatus. By integrating multiple imaging modes into one system, it achieves universality, allowing the device to handle both deep and wide imaging requirements without being limited to a single function.
2Device complexity
If a traditional navigation apparatus is used, then结构简单 (structure is simple), but imaging depth is limited
Solution Approach 1:
The patent divides the imaging system into distinct functional modules: open imaging module, endoscopic imaging module, switching module, and data processing module. This segmentation allows each module to be optimized for its specific function while maintaining overall system manageability, enabling deep imaging capability without excessive overall complexity.
3Adaptability or versatility
If dual-mode imaging is implemented to achieve both deep and wide imaging zones, then imaging versatility is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple imaging modes (open and endoscopic) into a single integrated apparatus with a unified switching mechanism. By merging these functions into one system rather than using separate devices, it achieves versatility while controlling complexity through integration and centralized control.

Implementation Method 1
the light splitting prism 21 is configured to split a light ray transmitted by the lens adapter 26 into two parts so as to feed into the color CCD camera 11 and the fluorescence CCD camera 12 respectively
Implementation Method 2
the first optical filter 22 is configured to filter one of the two divided light rays transmitted from the light splitting prism 21, and to output a light ray having a wavelength ranging between 400 nm ̃650 nm
Implementation Method 3
the second optical filter 23 is configured to filter the other of the two divided light rays transmitted from the light splitting prism 21, and to output a light ray having a wavelength ranging between 810 nm ̃870 nm
Implementation Method 4
optical molecular imaging has been a research hotspot due to its advantages such as low cost, high throughput, non-invention, non-contact, non-ionizing radiation, high sensitivity, and high specificity. Fluorescence molecular imaging is an important branch of optical molecular imaging, which uses an external light source to excite fluorescence probes within an organism, resulting in a NIR (near-infrared) fluorescence emitted by fluorescence probes
