Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If lens-based imaging systems are used to achieve high-resolution imaging, then image quality is improved, but device size and cost increase
Solution Approach 1:
The patent extracts the lens component from the imaging system and replaces it with a scattering medium. The scattering medium is a thin layer of particles suspended in a fluid, which scatters light from the object to create an image on the detector. This extraction of the lens eliminates the need for large optical components while maintaining imaging capability through computational reconstruction algorithms.
Solution Approach 2:
The patent replaces the mechanical optical system (lens) with a computational approach. Instead of using a physical lens to focus light, the system uses a scattering medium to diffuse light and computational algorithms to reconstruct the image. This substitution of mechanical optics with computational methods enables compact device size while achieving high-resolution imaging.
2Measurement precision
If lens-based imaging systems are used to achieve high-resolution imaging, then image quality is improved, but device cost increases
Solution Approach 1:
The patent employs a scattering medium composed of inexpensive particles (such as polystyrene beads or other dielectric particles) suspended in a fluid, which can be easily manufactured and replaced. This replaces expensive precision lenses with cheap, easily fabricated scattering materials, significantly reducing device cost while maintaining imaging functionality through computational reconstruction.
Solution Approach 2:
The patent changes the optical parameters of the imaging system by using a scattering medium with specific particle sizes, concentrations, and material properties. By adjusting these parameters (particle diameter, suspension density, refractive index), the system achieves desired imaging performance without requiring expensive precision optics, thereby reducing manufacturing cost.
3Adaptability or versatility
If traditional lens-based systems are used, then imaging is achieved, but field of view is limited
Solution Approach 1:
The scattering medium serves multiple functions: it scatters light to create images, can be reconfigured to adjust imaging parameters, and works with various detector types. The same scattering layer can be used for different fields of view by adjusting particle orientation or concentration, providing universal functionality that replaces multiple specialized optical components.
Solution Approach 2:
The patent employs a dynamic scattering medium where particles can be reconfigured using external fields (electric, magnetic, or acoustic). By applying these fields, the particle orientation and distribution can be changed in real-time, allowing the field of view and imaging parameters to be dynamically adjusted without changing the physical device structure.
