Flat Nose Pad Leverage Balance for Heavy Smart Glasses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional glasses nose pads fail to provide adequate leverage support for heavy glasses, leading to discomfort and potential slipping due to incorrect support points, causing pressure and discomfort on the nose.
Innovation Solution
A glasses assembly with a nose pad featuring a flat design that includes fixed portions on a support with a bended or non-bended angle, allowing the nose pad to act as a fulcrum and distribute the weight of the glasses, reducing discomfort and preventing slipping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a general glasses nose pad is placed on both sides of the root of the nose to support the glasses, then the glasses can be supported and prevented from slipping downward, but the support point is incorrect and cannot provide leverage effect, leading to discomfort and dents on the nose after long-term wear
Solution Approach 1:
The patent applies local quality by positioning the nose pad at a specific location on the nose bridge rather than at the root of the nose. The nose pad is designed to contact the nose bridge at a point that provides proper leverage balance, concentrating the support function at the correct anatomical location to avoid discomfort while maintaining reliability.
Solution Approach 2:
The patent introduces a dimensional change by extending the nose pad backward along the direction of the nose bridge. This extension allows the nose pad to engage with the nose bridge at a more effective leverage point, creating a fulcrum that balances the glasses weight and reduces harmful pressure on the nose root.
2Reliability
If the nose pad is designed to support heavy glasses, then the leverage balance can be achieved, but the structure becomes more complex with additional fixing portions and angled configurations
Solution Approach 1:
The support structure is segmented into distinct functional portions: a first fixing portion that inserts into the glasses frame, a second fixing portion that attaches to the nose pad, and the nose pad itself. This segmentation allows each component to perform its specific function while maintaining overall simplicity and modularity.
Solution Approach 2:
The first fixing portion is inserted into an accommodation portion of the glasses frame, creating a nested structure. This nesting approach allows the support structure to be integrated into the existing glasses framework without adding excessive external complexity, while still providing the necessary leverage balance for heavy loads.
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
The nose pad design achieves leverage balance, significantly reducing discomfort and preventing glasses from slipping downward, even with heavier frames, by distributing the weight effectively and providing increased support.
Implementation Method 1
the flat nose pad being pressed against the user's nose bridge to form a fulcrum, the glasses, smart glasses can achieve leverage balance through the flat nose pad

AI summary
A glasses assembly with a nose pad for high load includes: a pair of glasses, configured with an accommodation portion, where the glasses are smart glasses; a support, configured with a first fixing portion, at least one second fixing portion, and the first fixing portion inserted in the accommodation portion of the glasses; and a flat nose pad, two sides thereof respectively configured with a fixed portion, each of the fixed portions installed on the second fixing portion of the support. With the flat nose pad being worn on the user's nose bridge to form a fulcrum, the glasses, smart glasses can achieve leverage balance through the flat nose pad, and the flat nose pad can buffer the weight of the glasses, smart glasses, capable of significantly reducing the user's discomfort after wearing them for a long time, and preventing them from slipping downward.
