Opaque Surface Ridge Geometry for Dynamic Light-Reflecting Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for creating imagery on opaque materials using grooves and ridges are limited in producing dynamic light and shade effects, as they rely on fixed angles and flat frontal surfaces, which restrict the ability to produce complex, lustrous patterns that change with illumination and viewing angles.
Innovation Solution
The use of grooves and ridges that vary in direction and angle to calculate specific ridge-direction specifications, allowing for the creation of light-reflecting patterns that change brightness based on illumination and viewing angles, using these specifications to form surfaces that can be manually carved or machined into materials like MDF or aluminum, or used as molds for casting replica surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If fixed angles and flat frontal surfaces are used for grooves and ridges, then manufacturing simplicity is maintained, but the ability to produce dynamic light and shade effects is limited
Solution Approach 1:
The patent applies local quality by varying the ridge direction angles at different locations across the surface. Each local area has specifically calculated ridge directions that optimize light reflection for that particular zone, creating dynamic light and shade effects throughout the overall surface while maintaining a systematic manufacturing approach
Solution Approach 2:
The patent changes the angular parameter of ridges across different areas of the surface. By systematically varying ridge direction angles according to calculated specifications, the surface achieves dynamic illumination properties without requiring complex three-dimensional forms, resolving the contradiction between effect quality and manufacturing simplicity
2Illumination intensity
If varied ridge directions are used to create dynamic light patterns, then visual appeal and lustrous effects are improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent segments the surface into multiple zones, each with specific ridge direction specifications. This segmentation allows for systematic control of light patterns while maintaining manageable manufacturing precision requirements for each individual zone, rather than requiring uniform high precision across the entire surface
Solution Approach 2:
The patent performs preliminary calculation of ridge direction specifications before manufacturing. By pre-calculating the optimal ridge angles for each area based on desired light patterns, the manufacturing process can follow predetermined guidelines, reducing the need for complex real-time adjustments and improving overall manufacturing precision
3Shape
If complex ridge patterns are machined or carved, then dynamic image effects similar to three-dimensional objects are achieved, but production time and complexity increase
Solution Approach 1:
The patent uses a master template or digital model that contains the calculated ridge direction patterns. This master can be repeatedly copied or used to guide manufacturing processes, allowing dynamic light-reflecting patterns to be produced efficiently across multiple surfaces without requiring complex manual carving for each piece
Solution Approach 2:
The patent replaces complex manual carving or mechanical machining with systematic guidance based on calculated ridge directions. By using pre-determined angular specifications and potential automation, the production of dynamic patterns becomes more efficient while maintaining the visual complexity similar to three-dimensional objects

Function Achieved in This Case
Results in a lustrous, light-reflecting design that appears to change with perspective and lighting conditions, achieving a dynamic and complex image effect similar to three-dimensional objects, even on flat opaque surfaces, with varying levels of brightness and contrast that enhance visual appeal.
Implementation Method 1
uses grooves and ridges that come to a point to give definition between light and shade and produce the desired imagery solely from light and shade produced by the specific angles of the grooves and ridges on an overall surface relative to the angle of illumination to a source of light

AI summary
The present invention provides for a method of creating a lustrous surface in opaque materials using ridge angles, and valleys of varying depths cut, imprinted or pressed into the opaque material. The combination of the light reflecting ridges, angles to reflect more or less light, and a shadow effect arising from a combination of the valley depths and the angle of the ridges allows one to use light and shadow to create a pattern or series of patterns in the opaque materials. These patterns are created using a process whereby a design is first created, then cut into a master blank using some type of manual or computer-aided method. Next, this pattern is inlaid, pressed, or imprinted into a blank panel composed of the opaque material. In some embodiments, this opaque material is allowed to set, thus creating a finished article of manufacture in the form of a panel.
