Interchangeable Smart Glasses Nose Pad Locking Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart glasses designs are inconvenient for users who wear prescription glasses due to limited forehead-to-lens distance and fixed nose support pads that do not accommodate varying face and nose shapes, affecting compatibility and comfort.
Innovation Solution
A glass frame structure with interchangeable nose pads featuring hook or slot structures and a limiting member that allows for secure attachment and detachment, ensuring compatibility with different nose shapes and sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-size nose support pad is used on the glass frame, then the manufacturing process is simple, but the smart glasses cannot be worn by different users with varying face and nose shapes
Solution Approach 1:
The nose pad assembly is segmented into a nose pad component and a nose support pad component, allowing the nose pad to be detached and replaced. This segmentation enables different nose pads to be matched to different users while keeping the nose support pad structure relatively simple and integrated with the glass frame.
Solution Approach 2:
The nose support pad is designed with a universal interface (hook structure or slot structure) that can accommodate different types of nose pads. This universal design allows the same glass frame to serve multiple users with different facial characteristics, enhancing adaptability without requiring multiple frame designs.
2Ease of operation
If the hook structure is always locked in the slot structure, then the nose pad is securely attached, but the nose pad cannot be detached for replacement or adjustment
Solution Approach 1:
The limiting member is designed to be movable between a first position (unlocked) and a second position (locked). In the first position, the hook structure can be inserted into or removed from the slot structure. In the second position, the limiting member abuts against the hook structure to prevent detachment. This dynamic positioning allows the nose pad to be both securely attached during use and easily removable when needed.
3Reliability
If the limiting member is positioned to avoid the hook structure, then the nose pad can be installed and removed, but the nose pad may become loose or detach unintentionally
Solution Approach 1:
The limiting member transitions from a static to a dynamic design, allowing it to be temporarily moved to the first position during installation/removal operations, and then returned to the second position for secure locking. This dynamic behavior ensures both operational convenience and attachment reliability.
Solution Approach 2:
The elastic member automatically returns the limiting member to the second position (locked position) after installation or removal operations, providing self-locking functionality without requiring additional user actions. This self-service mechanism ensures the nose pad remains securely attached during normal use.

AI summary
A glass frame structure and a wearable device having the glass frame structure are provided. The glass frame structure includes a nose pad, a glass frame body, and a limiting member. The nose pad includes one of a hook structure or a slot structure, and the glass frame body includes the other one of the hook structure or the slot structure. The limiting member is located at a first position or a second position. When the limiting member is located at the first position, the limiting member avoids the hook structure, and the hook structure is located in the slot structure and is movable in the slot structure; and when the limiting member is at the second position, the limiting member abuts against the hook structure and the hook structure is locked in the slot structure.
