Resist-Layer Marker Structure for High-Precision Moiré Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing markers lack accuracy and clarity, especially under varying environmental conditions, and are difficult to manufacture efficiently.
Innovation Solution
A marker design comprising a base material layer, a first layer in a first color, and a second layer in a second color that partially conceals the first layer, with a thickness of 5 μm or less, and a protective layer with antireflection properties, allowing for high contrast and visibility even under sunlight or illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If markers are printed on paper, then they are easy to produce, but the boundary line of the mark is unclear and accuracy changes due to expansion and contraction
Solution Approach 1:
The patent uses a composite structure consisting of a transparent board (base material) with patterns formed on both front and back surfaces. This composite approach allows the marker to maintain dimensional stability while enabling moire effect display, resolving the contradiction between ease of production and manufacturing precision.
Solution Approach 2:
The patent employs thin film patterns deposited on both surfaces of a rigid transparent board. These thin films create the moire effect while the rigid substrate prevents expansion and contraction, ensuring accurate mark positioning and clear boundary lines.
2Ease of manufacture
If patterns are formed on both front and back surfaces to display moire, then moire can be displayed, but the moire is shielded by the patterns themselves and appears very dark
Solution Approach 1:
The patent applies different pattern densities and transparency characteristics to different regions of the front and back surfaces. By optimizing the local quality of pattern formation, the moire effect becomes visible and bright rather than dark and shielded, while maintaining the manufacturing simplicity of the dual-surface approach.
3Manufacturing precision
If metal plate with holes filled with resin is used, then marker accuracy can be achieved, but it takes a lot of time and labor to manufacture
Solution Approach 1:
The patent replaces the mechanical drilling and filling process with a deposition-based pattern formation method. Patterns are formed directly on both surfaces of a transparent board using coating or deposition techniques, eliminating the need for hole drilling and resin filling while achieving comparable or superior accuracy and dramatically improving manufacturing efficiency.
4Ease of manufacture
If metal plate or resin surface is used, then marker structure can be formed, but sunlight or illumination light may be reflected and markers may not be recognized correctly
Solution Approach 1:
The patent uses transparent or translucent materials with specific optical properties that allow light transmission rather than reflection. The patterns on the front and back surfaces are designed to create moire effects through light interference and transmission, ensuring that markers remain visible and recognizable under sunlight or illumination without suffering from harmful reflections.

AI summary
A high-precision marker, which is easy to manufacture, has a base material layer, a first layer which is laminated onto one surface of the base material layer, and which is observed in a first color, and a second layer which is partially laminated onto the first layer, is observed in a second color different from the first color, and partially conceals the first layer, wherein the first layer is observable in a region in which the second layer is not laminated, and the second layer is formed by a resist material.
