OTG Eyewear Mount with Adjustable Nose Bridge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Over-The-Glasses (OTG) eyewear designs lack flexibility and adaptability for use with head-mounted display apparatus and other optical components, being cumbersome and difficult to reconfigure, especially when needing to accommodate multiple or layered displays.
Innovation Solution
A display apparatus with a frame structure supporting protective lenses and a bridging member that includes adjustable nose bridge and coupling arms for securely attaching and positioning electronically energized display elements over the lenses, allowing for flexible mounting and reconfiguration to accommodate various optical arrangements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional OTG eyewear designs are used, then the structure is simple, but the adaptability for head-mounted displays and optical components is limited
Solution Approach 1:
The bridging member is designed as a universal mounting structure that can accommodate multiple types of optical components including head-mounted displays, filters, and polarizers. The coupling mechanism provides standardized interfaces that work with various display technologies and optical arrangements, making the eyewear adaptable to different applications without requiring separate designs for each component type.
Solution Approach 2:
The mounting system is divided into modular components including the bridging member, coupling arms, and adjustable nose bridge. This segmentation allows independent adjustment and configuration of each component to suit different optical arrangements and wearer requirements, enabling flexibility without creating an overly complex integrated structure.
2Adaptability or versatility
If fixed mounting structures are used, then the manufacturing is simple, but the reconfiguration capability is difficult
Solution Approach 1:
The coupling mechanism incorporates adjustable and removable features that allow the mounting structure to be dynamically reconfigured. The coupling arms can be adjusted to different positions and angles, and components can be removed or added as needed, providing reconfiguration capability while maintaining relatively simple manufacturing processes for each individual component.
3Ease of operation
If spacing for comfortable use is increased, then the wearer comfort is improved, but the device size increases
Solution Approach 1:
The adjustable nose bridge extends the mounting structure in the vertical dimension rather than increasing horizontal width. This allows sufficient spacing for comfortable wear over prescription glasses by utilizing the vertical space above the nose, without significantly increasing the overall device volume or width that would affect aesthetics and fit.

AI summary
A display apparatus for wearing over corrective eyewear has a frame structure that supports left- and right-side protective lenses, wherein each protective lens has a rear surface disposed to face toward the corrective eyewear, and a front surface disposed to face the outside-world object scene. A bridging member is hinged to the frame between the left- and right-side protective lenses, wherein the bridging member extends a nose bridge engagement member toward a viewer nose position, wherein the bridging member further has a coupling configured to removably suspend at least one output element of an electronically energized display system over the front surface of the left- or right-side protective lens.
