Ventilated Glasses with Adjustable Air-Permeable Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glasses with ventilation holes face issues in windy and sandy environments, as they cannot be closed, allowing dust to enter and compromising lens clarity due to moisture accumulation.
Innovation Solution
A ventilated glasses structure with an upper frame, lens unit, and lower frame, featuring pivot seats, inserting seats, adjusting units, and air-permeable holes that can be opened and closed by a positioning convex part to control airflow and dust entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If ventilation holes are provided on the frame to dissipate heat, then heat dissipation is improved, but dust entry increases in windy environments
Solution Approach 1:
The patent applies the dynamics principle by making the ventilation holes adjustable rather than fixed. The lower frame can be rotated relative to the upper frame to change the exposure state of the ventilation holes between open and closed positions, allowing the structure to adapt dynamically to different environmental conditions (hot vs. dusty)
Solution Approach 2:
The patent applies local quality by creating different functional zones within the frame structure. The upper frame has ventilation holes that can be selectively exposed or shielded, while the lower frame provides both structural support and the rotational adjustment mechanism. This localized functional differentiation allows heat dissipation when needed while preventing dust entry when required
2Temperature
If ventilation holes are kept open for heat dissipation, then cooling effect is improved, but moisture accumulation increases when not needed
Solution Approach 1:
The adjustable ventilation structure allows users to dynamically control the open/closed state of ventilation holes based on real-time needs. When cooling is required, holes are open; when moisture protection is needed, holes are closed, thereby maintaining lens clarity and preventing unnecessary moisture accumulation
3Object-affected harmful factors
If ventilation holes are closed to prevent dust entry, then protection is improved, but heat dissipation capability decreases
Solution Approach 1:
The rotational joint mechanism enables the lower frame to be positioned in different orientations, dynamically controlling whether ventilation holes are exposed or covered. This allows the system to switch between dust protection mode (holes covered) and heat dissipation mode (holes exposed) as needed

AI summary
Provided is a pair of glasses with a ventilated structure, mainly including an upper frame, a lens unit and a lower frame. The upper frame is provided with a lens groove and an inserting seat. The lens unit is arrange in the lens groove, and is provided with a plurality of air-permeable holes at the upper end of the lens unit. The lower frame is provided with an inserting section to be inserted into the inserting groove. The inserting section is provided with a positioning convex part operatively embedded in one of the adjusting holes of the adjusting unit to for a positioning. By positioning the position of the positioning convex part relative to each adjusting hole, the air-permeable holes of the lens are hidden or exposed on the upper frame.
