OTG Eyewear Frame Support Member for Nose Bridge Load Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional over-the-glasses (OTG) eyewear can cause misalignment and discomfort by resting on prescription eyewear frames, and may damage them due to downward pressure and improper positioning.
Innovation Solution
A frame support member that engages the user's nose to position secondary eyewear above and away from primary eyewear, reducing interference and incorporating adjustability through extendibility and flexibility to accommodate different users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If OTG eyewear is designed to fit over prescription eyeglasses, then safety protection is provided, but the prescription frames are pulled downwardly causing misalignment and discomfort
Solution Approach 1:
A frame support member is introduced as an intermediary component between the OTG eyewear and the prescription eyeglasses. This support member engages the user's nose and extends upward to contact the bottom surface of the OTG frame, thereby supporting the secondary eyewear above the primary eyewear and preventing downward pulling forces on the prescription frames.
2Reliability
If OTG frames rest on prescription frames to provide safety protection, then safety eyewear function is achieved, but downward forces are imparted on primary eyewear causing damage risk
Solution Approach 1:
The frame support member serves as a mediator that transfers the load from the OTG eyewear directly to the user's nose, bypassing the prescription frames. By positioning the support member's upper contact point on the bottom surface of the OTG frame and its lower engagement point on the user's nose, the prescription frames are excluded from the force transmission path, eliminating downward forces that could cause damage.
3Object-affected harmful factors
If OTG frames are pushed against the front of prescription lenses to deflect debris, then protection from debris is provided, but the prescription lenses may impinge the user's face or be damaged
Solution Approach 1:
The frame support member creates vertical separation between the OTG frame and the prescription lenses, preventing direct contact. This separation maintains the debris-deflecting function of the OTG frame while eliminating the harmful effect of lens impingement on the user's face and reducing the risk of damage to the prescription lenses.
4Stability of the object's composition
If a fixed support structure is used to separate OTG and prescription eyewear, then separation is achieved, but adaptability to different users is reduced
Solution Approach 1:
The frame support member incorporates dynamic characteristics through flexible portions that can bend and deform. This flexibility allows the support member to adapt to different nose shapes and sizes while maintaining the separation function. The flexible portion enables the structure to dynamically adjust to various users without compromising the stability of the separation between OTG and prescription eyewear.

AI summary
There is provided a frame support member for eyewear having a frame, with the frame including a nose bridge. The frame support member includes an attachment portion at a first end thereof for coupling the frame support member to the nose bridge of the eyewear, and a nose engaging portion at a second end thereof. The frame support member is configured to position the nose engaging portion below and behind the nose bridge for supporting the eyewear on a user. There is also provided eyewear that includes a frame for supporting at least one lens, a nose bridge for supporting the frame on a user, and the frame support member as herein described.
