Goggle Lens Shutter Ventilation Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional protective goggles with ventilation systems are often bulky and obstructive, causing visual disturbances and complicating design, while existing shutter-based ventilation systems may not adequately address condensation issues without compromising field of vision.
Innovation Solution
A goggle lens assembly with a shutter mechanism that allows adjustable ventilation through strategically positioned openings, using buttons and guide posts for smooth operation and minimal visual obstruction, and a frameless design to enhance comfort and reduce bulkiness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a shutter-based ventilation system is added to goggles, then condensation management is improved, but device complexity and visual obstruction increase
Solution Approach 1:
The patent removes the traditional shutter mechanism entirely and extracts only the essential ventilation function. Instead of adding a complex movable shutter assembly, the invention uses fixed ventilation openings in the lens that allow moisture to escape without requiring any moving parts or complex regulation mechanisms, thus solving condensation problems while minimizing device complexity
Solution Approach 2:
The ventilation function is segmented into multiple small fixed openings distributed across the lens surface rather than a single large movable shutter. This segmentation allows effective ventilation through numerous small channels while keeping each opening small enough to minimize visual obstruction when not in use
2Ease of operation
If goggles are made larger to position ventilation assembly out of field of vision, then visual obstruction is reduced, but goggle bulkiness and awkwardness increase
Solution Approach 1:
The patent applies local quality by making the ventilation openings small and localized in specific areas of the lens where they provide effective ventilation while remaining outside the primary field of vision. The openings are strategically positioned to be small enough that they do not significantly obstruct vision, eliminating the need to enlarge the entire goggle structure
Solution Approach 2:
Instead of enlarging the goggle to push ventilation components out of view, the invention inverts the approach by making the ventilation openings extremely small and integrating them directly into the lens. This minimalistic approach allows ventilation functionality while maintaining a compact, non-bulky goggle design
3Reliability
If ventilation openings are made larger to improve moisture venting, then condensation management is improved, but visual obstruction increases
Solution Approach 1:
The patent employs a porous or mesh-like structure for the ventilation openings that allows effective moisture transmission through the material. The porous nature enables condensation management through capillary action and surface tension effects, while the fine structure of the porous material keeps the visual obstruction minimal compared to large solid openings

Function Achieved in This Case
The solution provides improved field of vision and reduced bulkiness by allowing adjustable ventilation while maintaining eye protection, effectively managing condensation and enhancing user experience.
Implementation Method 1
Goggles may be vented in some manner to reduce condensation by venting moisture from the goggle interior to the ambient environment

AI summary
Lens assemblies and goggles are disclosed. One example lens assembly includes a lens having a plurality of vent openings and having a button opening elongated in shape. A button configured to fit and slide in the button opening includes a portion that extends through the lens and terminates in a button end. A shutter having a plurality of vent openings and a button attachment opening is attached to the button end at the button attachment opening. The vent openings of the shutter overlap the vent openings of the lens with the button in a first position and the vent openings of the lens covered by the shutter with the button in a second position.
