Adamantane Antireflective Coating for 3D Scanning Surface Mattification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current optical measurement technologies, particularly 3D scanning, face challenges with surfaces that are transparent, translucent, absorbing, reflective, or glossy, as existing antireflective coatings are either ineffective, contaminate systems, or require complex and time-consuming removal processes, and are not suitable for surfaces with protective coatings.
Innovation Solution
A composition comprising adamantane and a hydrocarbon solvent with a boiling point of 25°C or more, optionally with cyclododecane, which forms a thin, homogenous, and durable antireflective coating that evaporates or sublimates, allowing for high-quality 3D scans without the need for active removal and maintaining the protective coating on surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If pigment-containing agents are applied to the surface to be measured, then the surface becomes matt and opaque for optimal scanning, but the released pigments contaminate the measurement systems and areas
Solution Approach 1:
The patent employs a volatile coating agent that transitions from liquid to gas phase through evaporation, eliminating the need for pigment particles. The coating evaporates completely after application, providing temporary mattification during scanning without leaving residual contamination on the measurement system
Solution Approach 2:
The invention extracts the problematic pigment particles from the coating formulation, retaining only the volatile carrier substance. This extraction eliminates the source of contamination while preserving the coating's ability to modify surface optical properties temporarily
2Area of stationary object
If pigment-based coatings are applied to large surfaces, then coverage is achieved, but thorough removal of the coating layer becomes complicated and residual material remains
Solution Approach 1:
The volatile coating agent evaporates completely after application through phase transition from liquid to gas. This eliminates the need for mechanical or chemical removal processes, as the coating disappears naturally without leaving residues on large surfaces
3Measurement precision
If pigment-based coatings are applied to sensitive or fragile objects, then antireflective properties are achieved, but irreversible contamination or abrasions occur upon attempted removal
Solution Approach 1:
The coating undergoes complete evaporation through phase transition, eliminating the need for removal operations that could damage sensitive surfaces. The volatile agent disappears without trace, preventing both contamination and mechanical abrasion of fragile objects
Solution Approach 2:
By removing pigment particles from the formulation and using only volatile carrier substances, the invention eliminates materials that could cause contamination or abrasion, leaving the original surface completely intact after scanning
4Ease of manufacture
If cleaning agents are used to remove pigment-based coatings, then coating removal is achieved, but the process becomes extremely elaborate and time-consuming
Solution Approach 1:
The coating removes itself through evaporation rather than requiring external cleaning agents. The volatile substance transitions to gas phase and dissipates naturally, eliminating the need for elaborate cleaning procedures and significantly reducing time loss
Solution Approach 2:
The coating agent performs its own removal through spontaneous evaporation. The volatile carrier substance eliminates the need for separate cleaning operations by self-dissipating after completing its function of providing mattification during scanning
