Modular Prescription AR Display with Detachable OLED Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality (AR) displays are cumbersome and blurry when used with corrective eyewear, and without corrective eyewear, they fail to provide clear vision.
Innovation Solution
A modular prescription AR display that integrates a prescription lens into a frame, allowing the lens-frame assembly to be detached for use as conventional prescription eyewear, and includes removable AR components such as OLED displays and lenses that shape and direct images into the prescription lens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If AR display is designed to work with corrective eyewear, then vision correction is enabled, but device becomes bulky and cumbersome
Solution Approach 1:
The patent merges the AR display components with the corrective lens assembly into a single integrated unit. The AR display is positioned within the corrective lens housing, combining the vision correction function with the augmented reality display function in one compact structure, thereby eliminating the need for separate bulky AR headsets and corrective eyewear
Solution Approach 2:
The corrective lens assembly is designed to serve multiple functions: it provides vision correction for the wearer while simultaneously serving as the housing and optical pathway for the AR display. This multi-functional design eliminates the need for separate devices and reduces overall system complexity
2Device complexity
If AR display is designed without corrective eyewear, then device structure is simplified, but display becomes blurry or unclear
Solution Approach 1:
By merging the AR display with the corrective lens assembly, the system ensures that the display optics are optimized for the wearer's specific prescription. The corrective lens becomes part of the AR display optical pathway, ensuring clear image formation on the retina while maintaining the simplified integrated structure
3Ease of operation
If modular design is implemented, then ease of use as conventional eyewear is improved, but device complexity increases
Solution Approach 1:
The AR display system is segmented into modular components: a removable AR display module and a permanent corrective lens assembly. The AR module can be detached when not needed, allowing the user to wear the device as conventional eyewear, while the corrective lens remains integrated into the frame structure
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 solution provides a comfortable and clear AR experience by allowing the use of corrective lenses, reducing the weight and bulk of the AR display, and maintaining natural vision while presenting virtual images in real-world scenes.
Implementation Method 1
The removable AR components include one or more organic light emitting diode ('OLED') displays
Implementation Method 2
one or more lenses that shape and direct images into the edge of the prescription lens

AI summary
In an embodiment, a modular augmented reality display is provided that incorporates prescription eyewear that can be used separately by the wearer. In an embodiment, an image is generated from a removable display attached to the eyewear and directed into the edge of a prescription lens, which acts as a waveguide. The image is internally reflected within the prescription lens, and is directed to the wearer by an image combiner embedded within the prescription lens. In an embodiment, the augmented reality display includes a wearable belt pouch that includes a battery and support electronics connected to the eyewear so that the weight on the eyewear is reduced.
