Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pseudo three-dimensional imaging techniques, such as dot-matrix holography, fail to provide sufficient visual depth and realism, limiting their effectiveness in capturing attention and increasing sales, particularly in applications like instant scratch-off lottery tickets.
Innovation Solution
A method that utilizes actual objects to create true three-dimensional imagery by directing lasers at the objects and recording the images on a substrate, resulting in images with greater visual depth and enhanced security, making them more appealing and difficult to replicate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If dot-matrix holography is used to create pseudo three dimensional images, then the images can be produced with ornamental results, but the visual depth of the images is only marginal
Solution Approach 1:
The patent uses the actual object itself as the imaging target rather than creating piece-wise dot patterns. The laser beams directly interfere on the recording medium with the object present, creating a true three-dimensional image that copies the object's actual spatial structure, thereby achieving genuine visual depth and realism.
Solution Approach 2:
The patent transitions from two-dimensional dot-matrix patterns to true three-dimensional imaging by utilizing the actual spatial dimensions of the object. The interference fringes are recorded in three-dimensional space, preserving the object's depth information and creating images with authentic visual depth rather than simulated pseudo-3D effects.
2Illumination intensity
If pseudo three dimensional images are used on lottery tickets, then enhanced visibility and consumer attention can be achieved, but the security and difficulty of replication is insufficient
Solution Approach 1:
By using the actual object as the imaging target and recording its true three-dimensional structure through laser interference, the patent creates images that are extremely difficult to replicate. Commercial copiers and standard printing methods cannot reproduce the complex interference fringe patterns and spatial depth information, providing inherent security against counterfeiting.
Solution Approach 2:
The patent changes the fundamental parameters of image creation from conventional 2D printing to 3D laser interference patterning. The resulting images have unique optical properties including visual depth, color shifts, and geometric accuracy that cannot be replicated by changing standard printing parameters, thereby enhancing security.
3Illumination intensity
If actual objects are used to create true three dimensional imagery, then visual depth and security are increased, but the complexity of the imaging process increases
Solution Approach 1:
The actual object serves multiple functions simultaneously: it is the subject being imaged, the reference for spatial structure, and the element that defines the interference pattern. The object's own geometry and position automatically guide the laser beam interaction, eliminating the need for complex positioning systems or pre-programmed patterns, thereby reducing process complexity despite the advanced imaging capability.
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
The method produces images with increased visual depth and security, enhancing their appeal and making them more attractive for impulse-based purchases, such as lottery tickets, while being resistant to precise replication by commercial copiers.
Implementation Method 1
lasers are directed at, and impinge upon, the actual object and are subsequently split and directed to an image recording substrate
Data Source
AI summary
A method for producing true three dimension imagery includes positioning an object to be imaged and directing imaging laser beams to impinge upon the object. Splitting the imaging laser beams after the imaging laser beams have impinged upon the object is then accomplished, while redirecting the split imaging beams to a recording substrate.
