Goggle Lens Changing System With Sliding Lever Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current goggles have a fixed lens system, making it difficult for users to adapt to changing lighting conditions during active sports, as they either wear suboptimal lenses or carry multiple goggles, and existing interchangeable lens systems are inefficient for switching lenses.
Innovation Solution
A lens changing system featuring a sliding lever that transitions between closed and open positions to securely retain or remove lenses, utilizing a nub and receiving hole mechanism for secure attachment, allowing users to switch lenses based on lighting conditions or replace defective ones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If goggles have a fixed lens system, then the structure is simple and reliable, but the user cannot adapt to different lighting conditions without carrying multiple goggles
Solution Approach 1:
The goggle system is divided into separable components: the frame and the lens are independent elements that can be detached from each other. The lens mounting mechanism uses separate mounting points (nubs) on the frame that interface with corresponding recesses in the lens, allowing the lens to be removed and replaced without affecting the frame structure.
Solution Approach 2:
The lens is extracted as a removable component from the goggle system. The lens mounting mechanism provides dedicated attachment and detachment points, allowing the lens to be taken out of the frame and replaced with different lenses based on lighting conditions.
2Adaptability or versatility
If goggles have an interchangeable lens system, then the user can switch lenses for different conditions, but the lens changing process is complex and time-consuming
Solution Approach 1:
The lens mounting mechanism is segmented into discrete mounting points (nubs) located at specific positions on the frame. Each lens has corresponding recesses that align with these nubs, allowing for quick alignment and attachment without complex mechanisms.
Solution Approach 2:
The lens mounting system is designed to be self-aligning and self-securing. The nubs on the frame automatically align with the lens recesses when the lens is inserted, and the lens secures itself to the frame without requiring additional fastening steps or complex operations.
3Reliability
If the lens is securely retained to the frame, then the lens remains stable during use, but the lens cannot be easily removed for replacement
Solution Approach 1:
The retention mechanism is segmented into discrete mounting points (nubs) rather than a continuous fixed structure. This segmentation allows the lens to be securely held at multiple points during use while providing specific detachment points for easy removal.
Solution Approach 2:
The lens mounting system transitions from a static fixed state to a dynamic removable state. The nubs provide secure retention during normal use, but allow for easy detachment when the lens needs to be replaced, enabling the system to adapt between these two states.

AI summary
A goggle having a lens changing system is disclosed that includes a sliding lever that is traversable between a closed and opened position. The sliding lever, in the opened position, allows the lens to be released from the frame so that the user can either switch out the lens to a different lens that would be more appropriate for the current lighting conditions or to replace the current lens which may be defective. Additionally, the lens changing system has a nub and hole combination that further secures the lens to the frame so that the lens does not inadvertently dislodge off of the frame during active sports.
