Nose Bridge Extender for Over-the-Glasses Eyewear Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional over-the-glasses (OTG) eyewear often causes misalignment and discomfort by resting on prescription eyewear frames, and can damage them due to downward pressure, especially when intended to deflect debris.
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 downward forces, with adjustable features for flexibility and extendibility to accommodate different users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If OTG eyewear frames rest on prescription eyewear frames to provide support, then the OTG eyewear can be supported on the user's face, but the prescription eyewear frames are pulled downward causing misalignment and discomfort
Solution Approach 1:
The patent introduces a nose bridge extender as an intermediary component between the OTG eyewear frame and the prescription eyewear frame. This extender transfers the support function from the OTG frame directly to the user's nose, eliminating the downward pulling force on the prescription eyewear while maintaining proper lens alignment.
Solution Approach 2:
The nose bridge support structure is segmented into separate components: the prescription eyewear frame, the OTG eyewear frame, and an independent nose bridge extender. This segmentation allows each component to perform its specific function without interfering with others, particularly preserving the alignment of the prescription lenses.
2Object-affected harmful factors
If OTG frames deflect debris from the user's face as intended, then safety protection is provided, but the OTG frames push against the front of prescription lenses causing damage or facial impingement
Solution Approach 1:
The nose bridge extender acts as a mediator that positions the OTG frame further from the face, allowing it to effectively deflect debris without pushing against the prescription lenses. This intermediary structure creates sufficient spacing to eliminate the harmful contact while maintaining the protective deflection function.
3Adaptability or versatility
If OTG eyewear is designed to fit over prescription eyewear, then users can wear both simultaneously, but downward forces from secondary eyewear are imparted on primary eyewear causing discomfort
Solution Approach 1:
The nose bridge extender serves as a force-transferring intermediary that redirects the downward force from the OTG eyewear directly to the user's nose rather than transmitting it to the prescription eyewear frame. This maintains compatibility between the two eyewear types while eliminating the harmful downward force on the primary 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. A frame support assembly is also provided, which includes the frame support member and an extender to be coupled to the eyewear frame.
