Pivotable Eyewear Lens Retainer for Easy Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Protective eyewear often experiences broken lenses due to impacts, and users require multiple pairs for different lighting conditions, with lens replacement being cumbersome and sometimes necessitating complete eyewear replacement.
Innovation Solution
A pivotable lens retainer system for eyewear that transitions between a clamped and released position, allowing easy removal and replacement of lenses, including a lens retainer with a pivotable coupling to the eyewear frame and a latching mechanism for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional lens retention methods are used, then lenses are securely held in place, but lens replacement becomes complicated and cumbersome
Solution Approach 1:
The lens retainer is designed as a pivotable, movable component that transitions between a clamped position (securing the lens) and a released position (allowing lens removal). This dynamic mechanism enables easy lens replacement while maintaining secure retention during normal use, resolving the contradiction between ease of replacement and operational security.
2Adaptability or versatility
If multiple pairs of eyewear are used for different lighting conditions, then lighting condition coverage is improved, but device quantity and cost increase
Solution Approach 1:
The eyewear frame is designed with a universal lens retention system that can accommodate and securely hold multiple different lens types (e.g., clear lenses for daytime, tinted lenses for nighttime). This multi-functional capability allows a single pair of eyewear to replace multiple pairs, providing adaptability for different lighting conditions without increasing the quantity of eyewear needed.
3Reliability
If lenses are secured tightly to prevent movement, then lens stability is improved, but lens removal becomes difficult
Solution Approach 1:
The lens retainer employs a dynamic pivotable design that provides strong clamping force when in the closed position (ensuring reliable lens retention) but can be easily pivoted to a released position (enabling simple lens removal). This dynamic mechanism resolves the contradiction by providing both secure retention and easy removal through a single movable component.

AI summary
Eyewear of the present disclosure may include a frame having left and right rims, and a central bridge portion coupling the left rim to the right rim. A lens retainer has a first end pivotably coupled to an upper member of the central bridge portion and a second end releasably latched to a lower member of the central bridge portion. A lens is disposed on a front side of the eyewear frame and clamped to the frame by the lens retainer.
