Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional vein visualization device is used with near-infrared light conversion components, then blood vessel images can be visualized, but the device configuration becomes large and complicated
Solution Approach 1:
The patent applies wavelength conversion materials that convert near-infrared light into visible light, causing a color change effect that enables direct visualization of blood vessels through the skin without complex imaging systems. The conversion material changes the wavelength of transmitted light to make blood vessels visible to the human eye.
Solution Approach 2:
The patent extracts and eliminates unnecessary imaging components from the conventional system. By using wavelength conversion materials directly applied to the skin, the system removes the need for complex near-infrared cameras, image processing units, and display systems, retaining only the essential light source and conversion material.
2Measurement precision
If additional imaging components are used to convert near-infrared light into images, then blood vessel images can be obtained, but the configuration becomes cumbersome and inefficient
Solution Approach 1:
The wavelength conversion material performs the imaging function directly at the application site on the skin. The material itself converts the near-infrared light from the blood vessels into visible light, eliminating the need for separate imaging components and enabling immediate visualization without additional processing steps.
Solution Approach 2:
The patent merges the light conversion function and the imaging function into a single integrated system. The wavelength conversion material combines the optical conversion capability with the visualization function, allowing both near-infrared light conversion and blood vessel imaging to occur simultaneously at the same location.
