Swim Goggle Lens Frame Sliding Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional swim goggles often have left and right lens frames that are difficult to fit properly due to adjustment mechanisms affecting both frames simultaneously, making it inconvenient to replace individual lenses when they are broken, scratched, or of different prescriptions.
Innovation Solution
The swim goggles feature detachable and adjustable left and right lens frames with a connecting frame, first and second ribs, and joint members allowing the head strap to be drawn through, enabling separate assembly and sliding of the frames along tracks, facilitating easy replacement and adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a connecting element is used to adjust the span between left and right lens frames, then the distance between frames can be adjusted, but the positions of both lens frames are affected simultaneously making it difficult to achieve proper fit
Solution Approach 1:
The connecting frame is segmented into a middle portion and two separate adjustable portions (first and second lens frame assemblies), each capable of independent adjustment along the connecting frame. This segmentation allows each lens frame to be positioned independently to achieve proper fit while maintaining the ability to adjust the overall span between frames.
2Device complexity
If conventional swim goggles with fixed lens frames are used, then the structure is simple, but the lenses cannot be replaced when broken, scratched, or when different prescriptions are needed
Solution Approach 1:
The lens frames are designed with detachable connections to the connecting frame, transforming the structure from fixed to dynamic. This allows the lens frames to be easily attached and detached, enabling replacement of lenses when needed while maintaining a relatively simple overall structure through modular design.
3Ease of repair
If lens frames are made adjustable and detachable, then lenses can be replaced separately and quickly, but the structure becomes more complex with additional components
Solution Approach 1:
The connecting frame serves multiple functions: it connects the two lens frames, allows independent adjustment of each lens frame position, provides detachable connections for easy lens replacement, and maintains the overall structural integrity of the goggles. This multi-functionality reduces the need for additional separate components.

AI summary
A pair of swim goggles include a connecting frame being assembled with a left lens frame and a right lens frame and a head strap, characterized in that the left and the right lens frames respectively have a lens and a frame body, an upper side and a lower side of the frame body respectively provided with a track thereon, the connecting frame including a first rib and a second rib spaced apart from each other and respectively defining a connection part thereon for being detachably coupled with the respective track, whereby the left and the right lens frames are detachably and separately assembled with the respective first rib and second rib and therefore are slidable with respect to the first and the second ribs though the track.
