Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional synopters or binoviewers are bulky, expensive, and heavy, making them impractical for wear as spectacles due to their bulkiness and weight, and they fail to enhance the perceived depth and realism of 2D images without requiring batteries or software intervention.
Innovation Solution
A lens system integrating prism and atoric correction stages, implemented through a single optical surface, which redirects the line of sight forward and reshapes images to eliminate trapezoidal distortion, enhancing depth perception without stereoscopic information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional synopters or binoviewers are used to enhance depth perception of 2D images, then depth perception and realism are improved, but the device becomes bulky, heavy, and expensive
Solution Approach 1:
The patent merges multiple optical elements (prisms, lenses, mirrors) into a single integrated optical element that performs all necessary functions: splitting light between eyes, correcting image orientation, and providing depth perception. This consolidation eliminates the need for separate components, reducing device bulkiness and complexity while maintaining the synoptic effect for enhanced depth perception of 2D images
Solution Approach 2:
The integrated optical element serves multiple functions simultaneously: it acts as a beam splitter to direct light to both eyes, provides prismatic correction for image orientation, and creates the synoptic effect for depth perception. This multi-functionality replaces the conventional multi-component system, reducing overall device complexity and weight
2Reliability
If multiple optical elements are used in conventional synopters, then optical functionality is achieved, but manufacturing cost and device complexity increase
Solution Approach 1:
The patent combines multiple optical elements into a single integrated component that can be manufactured as one piece using conventional lens manufacturing techniques. This eliminates the need for assembling multiple separate elements, reducing manufacturing complexity and cost while maintaining full optical functionality including light splitting, image correction, and depth perception enhancement
3Measurement precision
If conventional synopters are worn as spectacles, then depth perception is enhanced, but comfort is reduced due to weight and bulkiness
Solution Approach 1:
By integrating all optical functions into a single element, the patent dramatically reduces the size and weight of the device. This allows the spectacles to be worn comfortably on the bridge of the nose without the bulkiness of conventional synopters, while still providing enhanced depth perception through the synoptic effect
Solution Approach 2:
The patent transitions from a three-dimensional multi-component assembly to a two-dimensional integrated optical surface that can be seamlessly incorporated into spectacle lenses. This dimensional simplification reduces the physical footprint and weight, improving wearing comfort while maintaining optical performance
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 lens system provides enhanced depth perception and realism of 2D images by eliminating trapezoidal distortion and reducing stereoscopic information, allowing users to experience increased depth and detail without batteries or software intervention.
Implementation Method 1
The prism correction stage may involve the rotation of the image about a Y-axis (essentially vertical axis) resulting in the line of sight of the user being orientated and directed straight forward
Implementation Method 2
The atoric correction stage may involve the reshaping of a trapezoidal view of the image into a rectangular view of the image
Implementation Method 3
the disclosure covers exploiting the synoptic effect of a two-dimensional (2D) image, whereby a user can look at the 2D image, through a device covered by this disclosure, and experience increased three-dimensional (3D) depth perception of the 2D image

AI summary
An optical device, such a lens, or that includes a lens or lenses. The lens or lenses each have integrated therein a prism correction stage and an atoric correction stage. The prism correction stage operates to redirect an image of an object or scene so that the line of sight associated with the eye or eyes of a viewer are directed straight forward towards the lens or lenses, whereby the vergence angle between the eyes is reduced to zero or near zero degrees. The atoric correction stage operates to reshape the image so that the trapezoidal distortion caused by the redirection of the image due to the prism correction stage is at least reduced if not eliminated, and without affecting the reduction of the vergence angle as a result of the redirection of the image by the prism correction stage. In a case where the optical device has two lenses, the prism correction stage and the atoric correction integrated into each lens operate in such a way so as to reduce or eliminate stereopsis and produce, for each eye, an identical, or monoscopic image such that the viewer sees the object or scene at optical infinity.
