Eyewear with Offset Nose and Temple Grips
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eyewear tends to slip off during athletic activities due to vigorous movements, with existing solutions either failing to prevent slippage or requiring additional accessories or expensive materials.
Innovation Solution
Incorporating nose grips and temple grips made of flexible materials with offset surfaces, such as stripes and V-shaped patterns, into the eyewear design to enhance grip and prevent slippage without the need for additional accessories or expensive materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional eyewear materials are used, then manufacturing cost is low, but the eyewear slips off during athletic activities
Solution Approach 1:
The patent applies local quality by incorporating grippy material only at specific contact points (nose pads and temple tips) rather than making the entire eyewear from expensive grippy material. This localized application maintains grip stability where needed while keeping overall manufacturing costs low.
Solution Approach 2:
The patent uses composite materials by combining conventional eyewear frame materials with grippy material at contact points. This creates a hybrid structure that leverages the advantages of both material types: the durability and cost-effectiveness of conventional materials and the high-friction grip of specialized materials.
2Reliability
If additional accessories are added to prevent slippage, then grip stability improves, but device complexity increases
Solution Approach 1:
The patent merges the grip-enhancing function directly into the existing eyewear structure by integrating grippy material into the nose pads and temple tips. This eliminates the need for separate accessories or add-on components, maintaining structural simplicity while improving grip stability.
Solution Approach 2:
The grippy material is built into the eyewear itself, allowing the eyewear to provide its own anti-slip function without requiring external accessories. The nose pads and temple grips serve dual purposes: structural support and friction-based grip prevention.
3Reliability
If rubber or grippy material is used for the entire eyewear, then slippage is reduced, but manufacturing cost increases
Solution Approach 1:
The patent applies local quality by incorporating grippy material only at specific contact points (nose pads and temple tips) rather than making the entire eyewear from expensive grippy material. This localized application maintains grip stability where needed while keeping overall manufacturing costs low.
Solution Approach 2:
The patent changes the material parameter (friction coefficient) only at critical contact points rather than throughout the entire eyewear structure. This selective parameter modification achieves the necessary grip stability while minimizing material cost increases.
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 eyewear stays securely in place during athletic activities, allowing for uninterrupted use without the need for readjustment or additional accessories, while being made with conventional materials at a lower cost.
