Vented Eyeglass Frame With Segmented Airflow Vents
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eyeglass frames with ventilation ports often provide either excessive or insufficient airflow, leading to fogging issues during athletic activities, and may compromise structural protection or aesthetics.
Innovation Solution
A vented eyeglass frame design featuring strategically placed outer and inner vents with supports that direct airflow behind the lenses, while maintaining structural integrity and aesthetics, and optionally includes removable inserts to adjust airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If ventilation ports are added to eyeglass frames to increase airflow, then fogging is reduced, but structural protection is compromised
Solution Approach 1:
The ventilation system is segmented into multiple small vents distributed across the frame rather than a single large opening. Each vent is positioned at specific locations (outer corners and bridge area) to collectively provide adequate airflow while maintaining structural integrity through the distributed load pattern.
Solution Approach 2:
Different regions of the frame are designed with different vent configurations based on local requirements. The bridge area has vents positioned to maximize airflow in that specific region, while outer corner vents provide additional ventilation without compromising the overall frame strength. Each location is optimized for its specific function.
2Object-affected harmful factors
If ventilation ports are made larger to increase airflow, then fogging is reduced, but aesthetics are compromised
Solution Approach 1:
The total vent area required for effective airflow is segmented into multiple smaller openings distributed across the frame. This segmentation allows each individual vent to be aesthetically pleasing while the collective arrangement provides sufficient total ventilation area to prevent fogging.
Solution Approach 2:
Vents are positioned at specific aesthetic locations on the frame (outer corners and bridge) where they provide maximum visual appeal. The bridge area vents are strategically placed to enhance airflow in the critical region while maintaining the natural contours and aesthetic quality of the frame design.
3Object-affected harmful factors
If ventilation ports are positioned obtrusively to maximize airflow, then fogging is reduced, but attractiveness is compromised
Solution Approach 1:
Vents are positioned at specific locations on the frame where they provide optimal airflow while remaining aesthetically pleasing. The outer corner and bridge positions are selected to maximize ventilation effectiveness in those regions while maintaining the overall attractive appearance of the eyeglass frame.
Solution Approach 2:
The vent positioning utilizes three-dimensional spatial arrangement, placing vents at the outer corners and bridge area rather than concentrating them in a single plane. This spatial distribution allows airflow to be optimized from multiple directions while maintaining aesthetic appeal from the front view.
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
Effectively reduces fogging by optimizing airflow without compromising protection or attractiveness, while allowing for adjustable airflow through secondary vents.
Implementation Method 1
Such increased airflow allows for the replacement of warm moist air behind the lenses with cooler and drier air

AI summary
A vented eyeglass frame is provided having a front frame extending laterally from a first end to a second end and for connecting to a temple at each of the first end and the second end. The front frame has first and second lens openings, with each lens opening being defined by a respective opening boundary at least partially circumscribing the corresponding lens opening. A bridge is defined between the first and second lens openings, and outer vents are provided at each end adjacent the corresponding lens openings. Inner vents are then provided at the bridge adjacent the lens openings. The lens opening boundaries each have a lens channel for at least partially enveloping a lens located at the respective lens opening, and each vent is defined by a gap in the corresponding lens opening.
