Lenticular 3D Object Design for Optical Illusions on Curved Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for creating 3D objects with multi-view optical illusions are limited by technical barriers, particularly in manufacturing and workflow, as they cannot efficiently produce high-resolution color patterns on doubly curved surfaces or compute and digitally model 3D objects with desired optical effects, restricting the application of lenticular and barrier-based methods to flat or simply curved surfaces.
Innovation Solution
The disclosure provides methods and systems for applying optical illusion effects to 3D objects by manipulating their optical properties, allowing for the creation of complex, doubly curved surfaces with lenticular and barrier-based displays, using ray tracing to determine lens geometry and image data, and enabling designers to control lens distribution, pattern placement, and material properties for customized designs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional lenticular printing methods are used, then flat or simply curved surfaces can be produced, but complex doubly curved surfaces cannot be effectively manufactured
Solution Approach 1:
The patent segments the manufacturing process into separate steps: first creating the base object with desired complex geometry, then applying lenticular elements to the already-formed surface. This allows doubly curved surfaces to be manufactured by combining object formation and lenticular application independently, rather than attempting to create both simultaneously with conventional methods.
Solution Approach 2:
The patent transitions from 2D lenticular printing to 3D object integration by embedding lenticular elements within or on the surface of three-dimensional objects. This dimensional change enables optical illusions on complex curved surfaces that cannot be achieved with flat 2D printing methods.
2Manufacturing precision
If high-resolution color patterns are required on doubly curved surfaces, then manufacturing precision must be high, but current manufacturing methods cannot achieve this
Solution Approach 1:
The patent applies lenticular elements to the base object after the base object has already been formed with its final complex geometry. This preliminary formation of the base object allows for precise control of the underlying structure before adding the optical elements, enabling high-resolution patterns on curved surfaces without the difficulty of trying to form both simultaneously.
3Adaptability or versatility
If computational modeling of 3D objects with optical effects is implemented, then design flexibility increases, but computational complexity and processing requirements increase
Solution Approach 1:
The patent uses computational modeling to create digital representations of 3D objects with embedded optical effects before physical manufacturing. This digital copying allows designers to visualize and adjust optical illusions in virtual space, providing design flexibility without requiring complex physical prototypes at each design iteration.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach enables the creation of 3D objects with dynamic, viewpoint-dependent optical illusions on complex surfaces, offering greater design flexibility and control, and allows for the production of unique, visually striking designs using various materials and techniques like 3D printing and precision glass moulding.
Implementation Method 1
When viewed from various viewpoints, the light refracted by the lenses allows individuals to perceive different portions of the interlaced image beneath the lenses.
Implementation Method 2
A parallax barrier may comprise a layer with tiny, precisely spaced slits that separates two sets of pixels. Each eye sees a different set of pixels, creating the illusion of depth through the effect of parallax.
