Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile devices lack integrated 3D camera capabilities that can function without electricity and provide glass-free 3D viewing experiences, limiting their applications in mobile communications and multimedia uses.
Innovation Solution
A mobile phone/device case or cover with a 3D camera system, featuring a V-shaped optical component with left and right arms acting as light guides and a focusing lens, along with a 3D viewer sheet that uses total internal reflection in prisms to form side-by-side images on an image sensor, enabling 3D viewing without special glasses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a 3D camera system is integrated into a mobile device case, then 3D imaging capability is added, but device complexity increases
Solution Approach 1:
The patent combines two cameras and a 3D viewer sheet into a single integrated 3D camera system within the mobile device case. The V-shaped optical component merges light guidance functions, and the prisms are integrated into a unified structure that captures stereoscopic images and displays them without requiring separate external equipment.
Solution Approach 2:
The 3D camera system is designed to serve multiple functions: it can capture 3D images and videos, display them on the mobile device screen, and potentially function as both a main camera and a selfie camera by rotating. The V-shaped optical component and prism assembly serve dual purposes in light guidance and image separation.
2Adaptability or versatility
If a V-shaped optical component with prisms is used to guide light, then 3D image formation is achieved, but manufacturing precision requirements increase
Solution Approach 1:
The V-shaped optical component is divided into four separate prisms arranged in two groups, where each prism handles a specific portion of the light path. This segmentation allows for easier manufacturing of individual prism components while maintaining the overall optical function through precise arrangement of the grouped prisms.
3Adaptability or versatility
If two cameras are integrated into a single case, then stereoscopic 3D capture is enabled, but device volume increases
Solution Approach 1:
The two cameras are positioned within the mobile device case in a nested or closely integrated arrangement, where the optical components of both cameras share the available space efficiently. The V-shaped optical component and prism assembly are compactly designed to accommodate both camera systems without significantly increasing the overall device volume.
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
Enables the mobile device to capture and display 3D images and videos, providing a glass-free 3D viewing experience across various applications, including mobile communications, multimedia, and photography, with the 3D camera system being versatile enough to function as both a main and selfie camera.
Implementation Method 1
a V-shaped optical component having left and right arms, which act as light guides to guide the light from an object, onto an image sensor
Implementation Method 2
light entering into one prism is reflected into the second prism due to total internal reflection at the first prism and the light entering the second prism is reflected due to total internal reflection at the second prism
Implementation Method 3
a focusing lens for focusing an image on the image sensor
