Eyewear Strap Connector With Adjustable Fasteners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eyewear connectors fail to securely connect eyewear ends to individual heads due to size inconsistencies and ineffective connection mechanisms, leading to discomfort and instability.
Innovation Solution
An apparatus comprising a strap with integral or attached connectors, each consisting of a base, head, and shaft, along with fasteners that securely attach to eyewear ends, providing adjustable length and textured surfaces for enhanced grip and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-sized strap is used, then the device complexity is reduced, but the adaptability to different head sizes is insufficient
Solution Approach 1:
The patent implements an adjustable strap length mechanism that allows the strap to be dynamically modified to fit different head sizes. The strap includes a first strap portion and a second strap portion that can be reconfigured, enabling the same strap to adapt to various users without requiring multiple different straps.
Solution Approach 2:
The strap is divided into multiple segments (first strap portion and second strap portion) that can be independently positioned and connected. This segmentation allows flexible reconfiguration of the strap length while maintaining a single unified strap structure, resolving the contradiction between adaptability and complexity.
2Reliability
If the connector is simplified, then the ease of manufacture is improved, but the connection reliability between eyewear and head deteriorates
Solution Approach 1:
The connector integrates multiple functions into a single component: it attaches to the eyewear temple, secures the strap, and provides adjustment capability. By merging the attachment mechanism, strap connection, and length adjustment into one integrated connector structure, the patent achieves reliable connection without significantly increasing manufacturing complexity.
3Adaptability or versatility
If the strap is made adjustable, then the adaptability to different sizes is improved, but the device complexity increases
Solution Approach 1:
The connector includes a self-adjusting mechanism with a movable portion that can be shifted between positions to change strap length. The design allows the user to easily adjust the strap without requiring additional tools or complex mechanisms, achieving adaptability while keeping the overall device relatively simple.
