Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional XR glasses are bulky and heavy due to integrated computing power and light sources, limiting their potential for a smaller, less visible, and smarter design with an improved user experience.
Innovation Solution
Separate the computing power and light sources from the XR glasses to a remote device, using optical fibers to transmit images to see-through waveguides, and employ an image director with electro-mechanical mirrors to dynamically alter optical paths for multi-plane image projection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If computing power and light sources are integrated into XR glasses, then image generation and display functions are achieved, but the device becomes heavy and bulky
Solution Approach 1:
The system is divided into two separate parts: a remote device containing the image generator and light sources, and XR glasses containing only the optical waveguides and display components. This segmentation removes the heavy computing power and light sources from the wearable device, significantly reducing weight while maintaining functionality through optical fiber transmission.
Solution Approach 2:
The patent extracts the image generation and light source components from the XR glasses and places them in a separate remote device. Only the essential optical components (waveguides, mirrors) remain in the glasses, extracting the bulk of the weight while preserving the core display function.
2Adaptability or versatility
If computing power and light sources are integrated into XR glasses, then complete XR functionality is achieved, but the device becomes bulky
Solution Approach 1:
The system separates XR functionality into a remote computing device and lightweight optical components in the glasses. The remote device handles all computation and light generation, while the glasses only manage optical path guidance and image projection, dramatically reducing volume.
Solution Approach 2:
Optical fibers serve as an intermediary medium to transmit images from the remote device to the XR glasses. This intermediary enables complete XR functionality to be achieved remotely while keeping the glasses themselves small and compact.
3Shape
If conventional integrated XR components are used, then image display is achieved, but the device cannot be made smaller and less visible
Solution Approach 1:
By segmenting the system into a remote image generator and compact optical components, the XR glasses achieve a sleek, minimal form factor that is smaller and less visible, while the remote device provides all necessary computational power and light sources to maintain excellent user experience.
Solution Approach 2:
Extracting the bulky components from the glasses leaves only the essential optical elements, enabling a compact, aesthetically pleasing design that is harder to detect, while the separated remote device ensures full functionality is preserved.
4Weight of moving object
If optical fibers are used to transmit images, then device weight and size are reduced, but image transmission quality must be maintained
Solution Approach 1:
Optical fibers act as a high-fidelity intermediary that transmits light-based image data from the remote device to the XR glasses with minimal loss. This optical transmission medium preserves image quality while enabling the lightweight design, avoiding the need for heavy electronic signal transmission components.

AI summary
An apparatus that supplies multi-plane images for viewing by a user includes an image generator, an image director, and a first output port. The image generator generates a first image to be seen by the user as being a first distance from a user point of view, and a second image to be seen by the user as being a second distance from the user point of view The first image is comprised of a number of optical wavelength components, and the second image is comprised of the number of optical wavelength components. The image director is configured to direct the first image to traverse a first optical path to the first output port of the apparatus, and to direct the second image to traverse a second optical path to the first output port of the apparatus. The first optical path corresponds to the first distance and the second optical path corresponds to the second distance. The first optical path and the second optical path have different lengths. The first output port is configured to connect to a first optical waveguide that is configured to guide the number of optical wavelength components to a user display device.
