Glasses Nose Pad Coupling Structure for Detachable Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional glasses frames lack robustness in fixing nose pads due to reliance on locking elements, which can detach under external forces and are vulnerable to wear, humidity, and sunlight exposure.
Innovation Solution
A glasses structure featuring a nose pad with a bendable device and a nose pad body, where the nose pad has a coupling device on one end and the bendable device has a corresponding coupling device, allowing detachable coupling to a containing trench in the glasses frame without locking elements, with the lens inserted to confine the coupling structure, providing enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If locking elements (screws) are used to fix the nose pad to the glasses frame, then the nose pad can be firmly fixed initially, but the structure becomes vulnerable to detachment under external forces and degradation from humidity and sunlight over time
Solution Approach 1:
The invention extracts and eliminates the locking elements (screws) from the glasses frame structure. Instead of using traditional screw-based fixation, the nose pad is directly integrated into the frame through a recess structure where the nose pad body fits into a recess in the frame, removing the vulnerable locking components that degrade from humidity and sunlight exposure.
Solution Approach 2:
The invention merges the nose pad fixation function directly into the frame structure by creating an integrated recess design. The nose pad body is received within a recess formed in the frame, combining what were previously separate components (frame, locking mechanism, nose pad) into a unified structure without detachable locking elements.
2Stability of the object's composition
If locking elements are used to secure the nose pad, then initial fixation is achieved, but the complexity of the structure increases and maintenance becomes more difficult
Solution Approach 1:
The invention removes the locking elements (screws, nuts, or other fastening components) from the glasses frame assembly. The nose pad is secured through a simple recess structure where the nose pad body fits into a cavity in the frame, eliminating the need for separate locking mechanisms and reducing overall structural complexity.
3Strength
If traditional screw-based fixation is used, then the nose pad can be firmly attached, but the structure is susceptible to damage from external forces such as collisions
Solution Approach 1:
The invention combines the nose pad and frame into a more integrated structure where the nose pad body is received within a recess in the frame. This unified design eliminates protruding locking elements that could act as stress concentration points during collisions, making the overall structure more resistant to impact damage while maintaining firm attachment.

AI summary
A glasses structure is provided. A nose pad of the glasses structure includes a bendable device and a nose pad body covering the bendable device, wherein the nose pad body and the bendable device have a coupling device disposed on respective ends thereof. The coupling device of the nose pad body and the coupling device of the bendable device cooperatively constitute a coupling structure. A glasses frame of the glasses structure has a lens insertion trench on one side thereof, and the glasses frame has a containing trench which is connected to the lens insertion trench. The coupling device of the nose pad is detachably coupled to the containing trench of the glasses frame. At least a lens is inserted into the lens insertion trench and leans against the coupling structure in the containing trench to confine the coupling structure.
