Transparent Reflective Panel Nanoclusters Wide-Angle Scattering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional transparent reflective panels have limited scattering angles, making them unsuitable for use as screens, as they struggle to effectively scatter projected images across a wide visible light range.
Innovation Solution
A large-area transparent reflective panel is created by arranging clusters of nano-scale unit metal bodies on a glass substrate, with the metal clusters spaced apart to increase the scattering angle across the entire visible light range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If micro-scale structures are used in conventional translucent film, then reflection for a specific angle is increased, but the scattering angle remains small making it hard to function as a screen
Solution Approach 1:
The patent divides the reflective surface into clusters of nanoscale metal bodies (10-1000 nm) arranged in periodic patterns. Each cluster acts as an independent scattering unit, and the collective arrangement of multiple clusters creates wide-angle scattering across the visible spectrum while maintaining high reflection intensity
Solution Approach 2:
The patent changes the size parameter of the scattering structures from micro-scale to nanoscale (10-1000 nm), and adjusts the periodic arrangement parameters of the clusters. This parameter transformation enables the structure to scatter light across the entire visible wavelength range (380-780 nm) achieving wide scattering angles while maintaining high reflectivity
2Illumination intensity
If conventional translucent film with micro diffraction grating is used, then reflection for a specific angle is enhanced, but the scattering angle is limited
Solution Approach 1:
The patent transitions from conventional two-dimensional micro diffraction gratings to a structured arrangement of nanoscale metal clusters with specific periodicity in both horizontal and vertical directions. This dimensional reorganization creates multiple scattering paths and achieves omnidirectional wide-angle scattering while preserving high reflection intensity across the visible spectrum
