Magnetic Corrective Optics Insert for AR Viewing Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing visual perception devices, such as augmented and virtual reality viewing devices, often lack user-specific accommodations, particularly corrective optics and interchangeable nose pieces, which are essential for comfortable and effective use by users with varying refractive errors.
Innovation Solution
A visual perception device with a magnetic attachment system that secures interchangeable corrective components, including lenses, to the viewing device frame, allowing for easy adjustment and compatibility with different users' prescriptions, and a nose piece that accommodates various nose shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed non-interchangeable nose piece is used, then the device structure is simple, but it cannot accommodate different users' nose shapes and weight distribution needs
Solution Approach 1:
The nose piece is divided into a nose piece body and a separate attachment mechanism that interfaces with the viewing device frame. This segmentation allows the nose piece to be removed and replaced with different variants (different sizes, shapes, and weights) while keeping the main device structure intact, thus achieving adaptability without proportionally increasing overall device complexity.
Solution Approach 2:
The attachment mechanism is designed with universal features that can accommodate multiple nose piece variants. The magnetic attachment system and slot interface create a universal mounting solution that works with different nose piece designs, allowing a single attachment mechanism to serve multiple functions across different user needs.
2Adaptability or versatility
If corrective optics are built into the device, then vision correction is provided, but the device cannot be adjusted for different users' prescriptions
Solution Approach 1:
The optical system is segmented into the viewing device (without built-in corrective optics) and separate corrective lenses that are integrated into the insert frame. This allows users to have custom-made corrective lenses according to their specific prescriptions while sharing a common viewing device platform, achieving prescription adaptability without designing multiple complete optical systems.
Solution Approach 2:
The insert frame acts as an intermediary component that bridges the viewing device and the user's eyes. It provides the interface for inserting corrective lenses with different prescriptions, allowing the viewing device to work with multiple prescription types without the prescriptions being built into the device itself.
3Ease of operation
If a magnetic attachment system is used, then corrective components can be easily attached and removed, but the attachment mechanism becomes more complex
Solution Approach 1:
The magnetic attachment system merges multiple functions into a single mechanism: the magnets provide both the attachment force and the alignment guidance. The slot interface combines mechanical guidance with magnetic attraction, creating a unified attachment system that achieves ease of operation through the synergistic combination of magnetic and mechanical features rather than through complex separate mechanisms.
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 customizable and comfortable fitting of corrective optics and nose pieces, enhancing user comfort and visual clarity by correcting refractive errors and improving light focusing on the retina.
Implementation Method 1
the first and second connecting components of the first magnetic set being attracted to one another by a north-south magnetic attraction when located in proximity to one another to secure the insert frame to the first viewing device frame component
Implementation Method 2
the corrective component being located in a path of the light to correct a refractive error of a lens of the eye and improve focusing of light on a retina of the eye

AI summary
A visual perception device is described. The visual perception device has corrective optics for viewing virtual and real-world content. An insert for the corrective optics is attached using a magnetic set, pins and/or a nose piece. Interchangeable nose pieces allow for height adjustments to accommodate different users. The visual perception device has pliable components to absorb forces exerted on a nose piece and a protective barrier for limiting electric shock or ingress of dirt.
