Eyewear Retention Cable Securing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eyewear retention systems are cumbersome, unreliable, and cause discomfort due to their design, particularly during dynamic activities like water sports, where eyewear can easily slip off.
Innovation Solution
A device and method for an eyewear retention system that incorporates a cable-securing mechanism, including a through-hole in the earpiece, a cable with an enlarged portion such as a melt bead, and a securing mechanism like a threaded tap hole and screw or a spring-loaded pivoting arm, to securely attach and adjust the cable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional strings, cloth bands, or chains are used to secure eyewear, then the eyewear can be retained around the wearer's neck, but the system becomes cumbersome and unreliable during dynamic activities
Solution Approach 1:
The retention system is segmented into distinct functional components: earpieces with integrated through-holes, a separate cable element, and securing mechanisms (enlarged portions or beads). This segmentation allows each component to perform its specific function optimally while maintaining overall system simplicity and reliability during dynamic activities.
Solution Approach 2:
The securing mechanism is merged directly into the earpiece structure through integrated through-holes and enlarged portions, eliminating the need for separate attachment devices. This merging reduces device complexity while maintaining reliable retention, as the cable secures directly to the earpiece without requiring additional external components.
2Reliability
If traditional retention methods are used, then eyewear can be kept secure, but they cause discomfort or abrasion to the wearer's ears or neck during extended use
Solution Approach 1:
The cable is positioned to contact only specific local areas (the earpiece structure and selected portions of the ear or neck) rather than distributing pressure across entire regions. The securing mechanisms concentrate retention force at precise points (through-holes and enlarged portions) while minimizing contact with sensitive skin areas, reducing discomfort and abrasion during extended wear.
3Adaptability or versatility
If traditional retention systems are used, then eyewear can be retained, but they lack easy adjustability or the ability to be quickly removed and reattached
Solution Approach 1:
The retention system incorporates dynamic characteristics through the cable-cable securing mechanism that can be easily adjusted, removed, and reattached. The cable can be detached from the earpiece by removing the securing mechanism (enlarged portion or bead from the through-hole), allowing quick removal and reattachment as needed, and enabling adjustment of cable length and tension for different wearing conditions.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a lightweight, easy-to-use, and adjustable eyewear retention system that securely holds eyewear during use and when not in use, reducing the risk of loss or damage, especially in water-based activities.
Implementation Method 1
The enlarged portion of the cable may comprise a melt bead formed at an end of the cable

AI summary
The present disclosure provides a device for securing eyewear, comprising an earpiece having a through-hole, a cable passing through the through-hole, and a securing mechanism configured to retain the cable within the through-hole. The securing mechanism may include a counterbore hole adjacent to the through-hole, configured to receive an enlarged portion of the cable, such as a melt bead formed at an end of the cable. Alternatively, the securing mechanism may comprise a threaded tap hole intersecting the through-hole and a screw configured to engage the threaded tap hole to secure the cable. In another embodiment, the securing mechanism may include a spring-loaded pivoting arm configured to engage the cable. The device allows for secure attachment of a retention cable to eyewear while maintaining a streamlined appearance.
