Solution Overview

Problem

Current augmented reality eyepieces lack efficient integration of 3D content display and interaction capabilities, limiting user engagement and environmental awareness.

Innovation Solution

The eyepiece incorporates an internal software application with multimedia computing facilities for 3D augmented reality content, utilizing RGB LED projectors, LCoS displays, and planar illumination facilities to project images onto see-through lenses, enabling seamless interaction with the environment through sensors, user inputs, and external data feeds.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional display methods are used in augmented reality eyepieces, then environmental awareness is maintained, but user engagement and interaction capabilities are limited

Engineering Contradiction:
Improveinteraction capabilitiesVSAvoidintegration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple display technologies (2D LCD, 3D LCoS, waveguide optics) into a single integrated eyepiece unit. The 3D display module and 2D display module are merged within the same optical path, allowing both environmental awareness and immersive 3D content to be displayed simultaneously through the same lens structure.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The eyepiece is designed to perform multiple functions: it can display 2D augmented reality content for environmental awareness, switch to immersive 3D content for user engagement, and provide different viewing modes (AR mode, 3D mode, transition mode) within a single device, eliminating the need for separate display systems.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If 3D display content is added to enhance user engagement, then interaction capabilities improve, but the complexity of integrating multiple display technologies increases

Engineering Contradiction:
Improvecontent display capabilitiesVSAvoidoptical system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The display system is segmented into independent modules: a 2D LCD module for augmented reality content, a 3D LCoS module for immersive content, and a waveguide module for optical transmission. Each module operates independently but shares the same optical path, allowing flexible content delivery without complex integration.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The waveguide module acts as an intermediary that receives light from both the 2D LCD module and the 3D LCoS module and directs it to the user's eye. This intermediary structure allows multiple content sources to be combined and delivered through a single optical channel, simplifying the overall system architecture.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

This disclosure concerns an interactive head-mounted eyepiece with an integrated processor for handling content for display and an integrated image source for introducing the content to an optical assembly through which the user views a surrounding environment and the displayed content, wherein the image source comprises a lighting system that directs light from a light source to a curved polarizing film that reflects a portion of the light to a reflective image display. The ratio of the height of the curved polarizing film to the width of the reflective image display is less than 1:1.
