Eyeglass Holder Buttonhole Attachment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing eyeglasses when not in use, such as mechanical clasps and magnets, are cumbersome, prone to losing retention over time, and can cause damage to garments or lead to the eyeglasses being lost or broken.
Innovation Solution
A device that securely attaches eyeglasses to a button on a garment, featuring a first portion for attachment to the garment and a second portion for holding the eyeglasses, allowing them to be carried safely and visibly, eliminating the need for cumbersome clasps or magnets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical clasps or magnets are used to attach eyeglasses to garments, then the eyeglasses can be secured when not in use, but the device becomes cumbersome and may lose retention force over time
Solution Approach 1:
The patent extracts the attachment function from complex mechanical clasps or magnets and implements it through a simple buttonhole engagement mechanism. The holder includes a buttonhole portion that directly receives a garment button, eliminating the need for additional clasps or magnetic components while maintaining secure attachment.
Solution Approach 2:
The patent employs a simple, inexpensive buttonhole portion made from basic materials that can be easily replaced if needed. This approach uses a straightforward structural solution rather than complex, expensive mechanical or magnetic components, aligning with the principle of using simple, replaceable elements.
2Reliability
If mechanical clasps are used to secure eyeglasses, then attachment is achieved, but the clasps fatigue, weaken and lose their ability to hold securely
Solution Approach 1:
The patent removes the problematic mechanical clasp component entirely and replaces it with a buttonhole engagement system. The buttonhole portion receives the button directly, creating a simple friction-based hold that avoids the fatigue and weakening issues associated with mechanical clasps.
Solution Approach 2:
The buttonhole portion automatically secures the eyeglasses through friction engagement with the button, requiring no additional fastening actions. The design allows the holder to maintain its holding ability over time through simple friction rather than mechanical tension that degrades.
3Reliability
If magnets are used to attach eyeglasses to garments, then secure attachment is achieved, but magnets can lose retention force over time and damage the garment in washing
Solution Approach 1:
The patent extracts the magnetic component entirely from the system and replaces it with a mechanical buttonhole engagement. This eliminates the risk of magnet damage to garments during washing while maintaining secure attachment through friction-based button engagement.
Solution Approach 2:
The buttonhole portion uses simple, non-magnetic materials that are safe for garment contact and washing. This approach replaces potentially harmful magnetic elements with inert, wash-safe components that pose no risk to the garment.
4Ease of operation
If clips are used to hold eyeglasses, then initial attachment works well, but clips break causing eyeglasses to come loose and break
Solution Approach 1:
The patent removes the fragile clip mechanism and replaces it with a buttonhole engagement system. The buttonhole portion is designed to be more durable than clips, providing a stable, break-resistant attachment method that maintains reliability over time.
