Eyeglasses Quick-Release Mechanism for Lens Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eyeglasses with replaceable lenses require complex and difficult assembly and disassembly processes, often causing accidental damage due to the need for multiple forces and complicated steps to engage and disengage protrusions and grooves.
Innovation Solution
The eyeglasses incorporate quick release mechanisms with positioning, engaging, and connecting members, featuring circular holes and slide pieces that allow for easy detachment and reattachment by aligning and pushing the mechanisms onto the lens, ensuring secure mounting without accidental removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If multiple protrusions and engaging grooves are used to stably connect the lens frame to the lens, then the connection stability is improved, but the assembly complexity increases and the operation becomes difficult
Solution Approach 1:
The connection mechanism is divided into two functional parts: a positioning member with positioning grooves that guide alignment, and an engaging member with protrusions that provide secure connection. This segmentation allows the complex connection function to be achieved through coordinated simple components, reducing overall assembly complexity while maintaining stability
Solution Approach 2:
The positioning member acts as an intermediary between the lens frame and engaging member, providing alignment guidance through positioning grooves. This intermediary component facilitates easy alignment and connection, reducing the difficulty of operation while ensuring stable connection through the coordinated action of all components
2Ease of operation
If large external force is applied to remove the lens from the lens frame, then the lens can be detached, but accidental damage to the lens frame or lens occurs
Solution Approach 1:
The engaging member is designed with elastic deformation capability, allowing it to dynamically adjust during the detachment process. When force is applied, the engaging member deforms elastically to release the connection, and then restores its original shape, enabling easy lens removal without requiring excessive force that could cause damage
Solution Approach 2:
The connection strength is made variable through the elastic properties of the engaging member. By changing the deformation state of the engaging member, the connection can be easily released during removal while maintaining strong connection during normal use, thus reducing damage risk during lens replacement operations
3Adaptability or versatility
If the lens frame is removed from the lens before replacing the lens, then lens replacement can be performed, but the replacement steps become complicated and difficult to operate
Solution Approach 1:
The connection system is segmented into a positioning member that remains with the lens frame and an engaging member that can be independently manipulated. This segmentation allows the engaging member to be detached and reattached without removing the lens frame, simplifying the lens replacement process into a single-step operation while maintaining full lens replacement capability
Solution Approach 2:
The positioning grooves are pre-formed in the positioning member to guide the alignment of the engaging member. This preliminary structural preparation enables the engaging member to be quickly and accurately reattached to the lens frame after lens replacement, reducing the complexity of replacement steps while ensuring proper alignment and connection

AI summary
A pair of eyeglasses includes a lens body having two engaging grooves formed in left and right sides thereof and respectively having an engaging section, and two quick release mechanisms detachably disposed on the left and right sides of the lens body and each including a positioning member defining a positioning slot and a receiving hole, an engaging member detachably engaged to the engaging section of a respective engaging groove and having a slide piece portion and a stop block portion, and a connecting member disposed on rear sides of the positioning member and the engaging member. When the engaging member of each quick release mechanism is pressed into the positioning member, the slide piece portion is located in the positioning slot and the stop block portion is received in the receiving hole to allow detachment of each quick release mechanism from the lens body.
