Innovation Solution
A quick release mechanism featuring a connecting member with an accommodating groove and a fastener member, including an operating portion, latching portion, and pivotable elements, allowing for easy attachment and detachment of eyeglass components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If multiple protrusions and engaging grooves are used to stably connect lens frame and lens body, then connection stability is improved, but assembly and disassembly complexity increases
Solution Approach 1:
The engaging groove is segmented into two functional sections: a wide opening section for easy access and a narrow engaging section for secure connection. The latching portion is correspondingly segmented with a wide portion that fits in the opening section and a narrow portion that engages in the engaging section. This segmentation allows the connection to be both stable and easy to assemble/disassemble.
Solution Approach 2:
The latching portion acts as an intermediary element between the connecting member and the engaging groove. It mediates the connection by rotating between locked and unlocked positions, providing a simple mechanical interface that replaces complex multi-point engagement while maintaining connection stability.
2Ease of operation
If large external force is applied to disengage protrusions from engaging grooves, then lens body removal is achieved, but risk of component damage increases
Solution Approach 1:
The latching portion is designed to rotate dynamically between locked and unlocked positions. When the operating portion is actuated, the latching portion rotates to disengage from the engaging section, allowing the connecting member to be removed without applying large forces that could damage components.
Solution Approach 2:
The patent replaces the traditional mechanical force-based disengagement system with a rotation-based latching system. Instead of pulling or forcing components apart, the user simply rotates the operating portion to unlock the latching mechanism, eliminating the need for large external forces and reducing damage risk.
3Stability of the object's composition
If multiple steps are required for lens body replacement, then connection stability is maintained, but replacement time increases
Solution Approach 1:
The latching portion is pre-positioned in the engaging section during manufacturing, creating a ready-to-lock configuration. When assembling, the connecting member is simply inserted and the latching portion automatically engages, eliminating the need for multiple adjustment steps and reducing replacement time while maintaining connection stability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates quick and simple replacement of eyeglass components, reducing the risk of damage and enhancing the ease of repair and modularization.
Implementation Method 1
The latching portion has two long sides, and two short sides each connected between one ends of the long sides. The maximum length of the latching portion is measured between the two short sides. Each short side has a width measured in the top-bottom direction less than the width of the opening section and the diameter of the engaging section.

AI summary
A quick release mechanism for eyeglasses includes a connecting member for detachably disposing on one side of an eyeglass component of the eyeglasses, and a fastener member for positioning the connecting member on the eyeglass component and including an operating portion and a latching portion having two short sides. The eyeglass component is formed with an engaging groove having an engaging section and an opening section. The operating portion is operable to move between a locking position, in which neither of the short sides of the latching portion is facing the opening section; and an unlocking position, in which one short side of the latching portion is facing the opening section, and the latching portion is allowed to move out of the engaging section through the opening section and thereby allow the connecting member to detach from the eyeglass component.
