Goggle Support Frame for Detachable Facemask Venting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Facemasks not directly attached to goggles can lead to exhaled air entering vents, causing increased humidity and temperature inside the goggles, resulting in condensation on lenses, and existing attachments often obscure vents or create gaps that allow external air to enter.
Innovation Solution
A support frame with a nose bridge and legs that attaches to the bottom surface of goggles, ensuring vents remain unobstructed and preventing exhaled air from entering, while maintaining airflow and reducing condensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a facemask is not directly attached to goggles, then the facemask can be easily removed and adjusted, but exhaled air enters the vents causing increased humidity and temperature inside the goggles
Solution Approach 1:
A support frame is introduced as an intermediary component between the facemask and goggles. The support frame includes a nose bridge and two legs that attach to the bottom surface of the goggles, creating a structured connection that properly positions the facemask and directs exhaled air away from the vents while maintaining ease of attachment and removal.
2Reliability
If existing attachment methods are used, then the facemask can be secured to the goggles, but the attachment structure obscures vents or creates gaps that allow external air to enter
Solution Approach 1:
The attachment system is segmented into separate functional components: the support frame with nose bridge and legs for structural attachment, and the facemask for facial coverage. This segmentation allows the support frame to securely attach the facemask while its legs are positioned to not obstruct the vents, maintaining both attachment security and ventilation efficiency.
Solution Approach 2:
Different parts of the support frame have different functions and properties. The nose bridge provides structural support and attachment points, while the legs are designed to extend downward without obstructing the vents. This local differentiation ensures that each component performs its specific function optimally - attachment security in one area and ventilation preservation in another.
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
Prevents condensation on goggles by maintaining airflow and reducing humidity inside the goggles, enhancing comfort and clarity during use.
Implementation Method 1
The nose bridge and the two legs are arranged between a rearward facing surface of the pair of goggles and the bottom vents such that they do not obstruct airflow through the at least one bottom vent when the support frame is attached to the goggles
Implementation Method 2
the at least one vent is substantially unobstructed when the facemask is attached to the goggles by the support frame

AI summary
A support frame (18) for releasably attaching a facemask (4) to a goggle (2) including at least one vent (10, 12, 14) and its method of use are disclosed. In one non-limiting embodiment, the support frame includes a nose bridge (200) and two legs (202) extending from the nose bridge. The nose bridge and the two legs are adapted and arranged to releasably attach the facemask to a bottom surface (20) of the goggles. The nose bridge and two legs are arranged such that the at least one vent is unobstructed when the facemask is attached to the goggles by the support frame.
