Removable Bridge Mechanism for Universal Sunglass Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions for wearing sunglasses over prescription eyewear are limited, as they often require bulky overlays, specialized clip-ons, or self-tinting lenses that lack style variety and are not interchangeable with different sunglasses or prescription eyewear frames, and do not allow for the use of any brand or style of sunglasses.
Innovation Solution
A removable, adjustable mechanism that clips onto the sunglasses and hooks onto the prescription eyewear at the nose bridge, allowing any style of sunglasses to be worn over existing prescription eyewear without the need for specialized frames or lenses, and can be easily switched between different sunglasses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If specialized encasing sunglasses are used to cover prescription eyewear, then the sunglasses can be worn over prescription lenses, but the design variety and style choices are limited and the structure is bulky
Solution Approach 1:
The invention divides the system into two independent components: the prescription eyewear and the sunglasses, connected by a separate bridge mechanism. This segmentation allows each component to maintain its original design integrity while enabling compatibility between them, eliminating the need for bulky encasing frames.
Solution Approach 2:
The patent introduces an intermediary bridge mechanism that connects the prescription eyewear to the sunglasses. This mediator component enables the connection between two otherwise incompatible systems, allowing standard sunglasses to be worn over prescription glasses without requiring specialized encasing designs.
2Adaptability or versatility
If clip-on sunglasses are used to attach to prescription eyewear frames, then style variety is improved, but the mechanism requires specialized construction of the prescription frames and separate handling when not in use
Solution Approach 1:
Instead of attaching the sunglasses to the prescription frames (as with clip-ons), the invention inverts the attachment approach by connecting the prescription eyewear to the sunglasses through a bridge mechanism that attaches to the sunglasses' existing frame structure. This eliminates the need for specialized prescription frame construction.
Solution Approach 2:
The bridge mechanism is designed to be universal, compatible with various sunglasses frame types and styles. This multi-functionality allows the same bridge component to work with different sunglass designs, eliminating the need for specialized clip-on mechanisms for each frame type.
3Device complexity
If magnetic clip-ons are used to connect to prescription eyewear, then the attachment mechanism is simplified, but the prescription eyewear frames must have specialized construction to accommodate magnets
Solution Approach 1:
The invention reverses the attachment approach by placing the magnetic or mechanical connection mechanism on the sunglasses side rather than requiring modifications to the prescription frames. This allows standard prescription eyewear to be used with the sunglasses attachment system.
Solution Approach 2:
The bridge acts as an intermediary that provides the magnetic or mechanical connection mechanism, eliminating the need to modify the prescription frames. The mediator component handles all attachment requirements, allowing both standard prescription glasses and standard sunglasses to be used together.
4Ease of operation
If self-tinting lenses are integrated into prescription lenses, then the switching between sunglasses and prescription glasses is eliminated, but the style variety and brand choices are restricted and the lenses cannot be prevented from tinting indoors
Solution Approach 1:
The invention separates the sunglass lenses from the prescription lenses, allowing them to be independent components. This segmentation enables the user to keep their preferred prescription lenses and add sunglass functionality through separate attachable lenses, maintaining both style choices and prescription accuracy.
Solution Approach 2:
The system provides dynamic flexibility by allowing the user to attach or detach sunglass lenses as needed, rather than having a fixed self-tinting solution. This dynamic approach enables style changes and brand selections while maintaining the ability to use prescription lenses independently when sunglasses are not needed.
