Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If visible light and near-infrared light are used for photon diagnosis and therapy, then the technology can be implemented with current devices, but the light cannot penetrate deep into human tissues, restricting diagnosis and therapy to body surfaces and larger cavities
Solution Approach 1:
The patent introduces an intermediary substance (contrast agent or photosensitizer) that mediates between the laser light and deep tissue. This intermediary absorbs the laser energy and converts it to fluorescence or other detectable signals, enabling deep tissue penetration without direct laser damage to the tissue. The intermediary acts as a bridge that allows energy transfer from the laser to the target tissue at depth without causing harmful effects.
Solution Approach 2:
The patent changes the parameter of light wavelength by using multiple wavelengths of laser light (not just visible or near-infrared). By selecting specific wavelengths that correspond to absorption peaks of contrast agents or photosensitizers, the system achieves deep tissue penetration. The parameter change from standard visible/NIR wavelengths to specific wavelengths optimized for tissue penetration and contrast agent absorption enables the solution.
2Length of moving object
If multiple wavelengths of laser light are used to penetrate deep tissue and analyze feedback fluorescence, then deep tissue diagnosis and therapy can be achieved, but the device complexity increases with multiple laser sources and coupling modules
Solution Approach 1:
The patent makes the laser light source module universal by enabling it to output multiple wavelengths of laser light. Instead of requiring separate laser sources for different wavelengths, a single multi-wavelength laser source performs all the functions. The coupling and switching module also serves multiple purposes: coupling different laser wavelengths, switching between them, and directing them to the appropriate targets. This multi-functionality reduces the overall number of components needed.
Solution Approach 2:
The patent merges multiple laser light sources into a single integrated laser light source module that can output multiple wavelengths. It combines the coupling and switching functions into a single module that handles both tasks. By merging these separate components, the system achieves the same functionality with fewer discrete parts, reducing device complexity while maintaining the capability to penetrate deep tissue with multiple wavelengths.
