Adjustable Nose Pad Mechanism for Glasses Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing designs for virtual reality and augmented reality glasses require multiple sizes to accommodate varying nose shapes and bridge heights among different populations, leading to increased costs and reduced consumer desire due to the need for multiple devices or interchangeable nose pads.
Innovation Solution
A glasses design featuring an adjustable nose pad mechanism with a sliding positioning section, locking slots, and an adjustment mechanism that includes a pressing member and positioning member, allowing for up and down movement of the nose pad within a groove, facilitated by elastic elements for easy adjustment and secure locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple types of glasses are designed to satisfy different user groups, then the fit for various nose shapes and bridge heights is improved, but the cost increases and consumer desire to purchase decreases
Solution Approach 1:
The nose pad is designed with a sliding mechanism that allows it to move vertically along the bridge. The adjustment mechanism includes a pressing member that can shift the nose pad between different positions, enabling a single pair of glasses to adapt to various nose shapes and bridge heights dynamically
Solution Approach 2:
The glasses are designed with a universal adjustment mechanism that serves multiple functions: it allows the nose pad to be positioned at different heights, locked securely, and adjusted by users. This multi-functional design enables one pair of glasses to replace multiple fixed-size versions
2Adaptability or versatility
If an adjustment mechanism is added to allow nose pad movement, then the adaptability to different users is improved, but the device complexity increases
Solution Approach 1:
The adjustment mechanism is divided into distinct functional components: a pressing member for initiating movement, a positioning member for locking/unlocking, and a sliding nose pad with locking slots. This segmentation allows each component to perform its specific function simply, reducing overall complexity while maintaining adjustability
Solution Approach 2:
The adjustment mechanism is designed to be user-operable without requiring tools or complex procedures. The pressing member can be easily pressed by the user to release the positioning member, allowing the nose pad to be adjusted and relocked at the desired position through simple manual operation
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
This solution enables a single pair of glasses to fit various users by allowing simple and effective adjustment of the nose pad position, reducing the need for multiple devices and minimizing user operation, thereby addressing the cost and fit issues associated with diverse nose shapes and bridge heights.
Implementation Method 1
the adjustment mechanism further comprises an elastic element disposed between the glasses frame and the positioning member to push the positioning member from the release position to the positioning position

AI summary
Glasses (100, 100a) have a groove (11) provided in a vertical direction on a bridge (13) of a glasses frame (10). A support section (22) of a nose pad (20, 20a) of the glasses (100, 100a) is connected to an end portion of a positioning section (21, 21a) of the nose pad (20, 20a), the positioning section (21, 21a) is slidably disposed in the groove (11), and the positioning section (21, 21a) has a plurality of locking slots (211, 211a) and a limiting slot (212, 212a). An adjustment mechanism (30, 30a) of the glasses (100, 100a) is disposed at the glasses frame (10), and a pressing member (31, 31a) of the adjustment mechanism (30, 30a) is disposed perpendicular to the groove (11), where one end of the pressing member (31, 31a) protrudes from one side of the groove (11), and the other end penetrates through the groove (11) and the limiting slot (212, 212a). A positioning member (32, 32a) of the adjustment mechanism (30, 30a) is connected to the other end of the pressing member (31, 31a). The positioning member (32, 32a) moves from a positioning position to a release position by pushing of the pressing member (31, 31a).
