Headworn Supports with Passive Venting Gaps and Removable Lens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eyewear products face issues such as insufficient ventilation, inadequate protection, and insufficient ballistic impact resistance, leading to wearer discomfort, visual impairment, and potential harm.
Innovation Solution
The design incorporates a lens with a frame configuration that allows for passive venting through gaps between the lens and frame, while also providing structural support and ballistic impact resistance through a retention assembly and specific frame features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lens is fully enclosed by the frame for protection, then protection against impacts is improved, but ventilation is insufficient leading to condensation and wearer discomfort
Solution Approach 1:
The frame is segmented to provide discrete contact points rather than continuous contact, creating gaps between the lens and frame that enable ventilation while maintaining protection. The retention assembly uses multiple contact points (at least two) to secure the lens while leaving spaces for air flow.
Solution Approach 2:
Different regions of the lens-frame interface have different functions: contact points provide structural support and protection, while gaps between contact points provide ventilation. This local differentiation allows simultaneous achievement of protection and ventilation.
2Stability of the object's composition
If the frame contacts the lens at multiple points for stability, then lens positioning is improved, but ventilation areas are reduced
Solution Approach 1:
The contact between frame and lens is segmented into discrete contact points rather than continuous contact. This segmentation provides stable lens positioning at specific points while creating gaps for ventilation between the contact points.
Solution Approach 2:
The frame contacts the lens at minimal necessary points (at least two contact points) rather than along the entire perimeter. This partial contact provides sufficient stability for lens positioning while maximizing ventilation areas.
3Volume of moving object
If the frame extends close to the lens for compact design, then device size is reduced, but ventilation capability is diminished
Solution Approach 1:
The frame is designed with segmented contact points that allow the frame to be compact while maintaining ventilation gaps. The segmentation enables close proximity without continuous contact, preserving both compactness and ventilation.
4Reliability
If the retention assembly secures the lens firmly for protection, then impact resistance is improved, but lens removal and replacement becomes difficult
Solution Approach 1:
The retention assembly provides dynamic retention: firmly securing the lens during normal use and impact events, while allowing intentional removal when needed. The system transitions between a retained state (during use) and a removable state (for maintenance or lens replacement).
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
This solution effectively reduces condensation on the lens, enhances wearer comfort, and provides protection against ballistic impacts, ensuring clear vision and safety in various conditions.
Implementation Method 1
an upper edge of the lens and a lower edge of the frame are spaced apart between contact points to allow venting of the lens

AI summary
Provided herein are examples of bead worn supports, such as eyewear, configured to provide passive venting by providing pathways between a lens and a frame and/or by providing a smooth anterior profile to allow a laminar flow of air on an anterior surface of the lens. The pathways through the frame and lens of the eyewear can be configured such that they do not provide a direct path to the eye of a wearer. The headworn supports provided hemin can provide venting while reducing or preventing unwanted light, particles, or other debris from contacting the eye of the user. The headworn supports can also be configured to exhibit excellent ballistic performance.
