Goggle Lens Replacement Structure With Movable Locking Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing goggle lenses are difficult to disassemble and replace due to the need for manual separation and tool-assisted disassembly, making the process labor-intensive and time-consuming.
Innovation Solution
A goggle lens replacement structure featuring a spectacle frame with limiting and embedding convex portions, a spectacle lens with corresponding holes and fitting portions, and a positioning device with a movable element, allowing easy separation and assembly of the lens from the frame using the movable element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lens is combined and fixed with the lens mounting groove using conventional methods, then the lens can be securely positioned, but the disassembly and replacement process becomes labor-intensive and time-consuming
Solution Approach 1:
The positioning device is divided into a fixed part (embedded in the frame) and a movable part (attached to the lens). This segmentation allows the lens to be securely positioned during normal use while enabling easy disassembly by simply moving the movable part, thus resolving the contradiction between secure positioning and easy replacement.
Solution Approach 2:
The positioning device transitions from a static fixed structure to a dynamic system with a movable element. The movable part can be shifted between a locked position (for secure positioning) and an unlocked position (for easy disassembly), allowing the same structure to provide both reliable positioning and convenient replacement.
2Reliability
If conventional lens assembly methods are used, then the lens can be securely fixed, but the assembly process requires tool assistance and is time-consuming
Solution Approach 1:
The positioning device is designed to be self-operating without requiring external tools. The movable part can be easily shifted by hand between locked and unlocked positions, allowing users to assemble and disassemble lenses independently and efficiently, thus improving productivity while maintaining secure fixation.
3Reliability
If a fixed positioning structure is used, then the lens can be securely mounted, but the replacement process becomes complex and labor-intensive
Solution Approach 1:
The positioning device incorporates a movable element that can be quickly shifted between locked and unlocked states. This dynamic design allows the lens to be securely mounted during normal use but can be rapidly disassembled by simply moving the element, significantly reducing replacement time while maintaining mounting stability.
Solution Approach 2:
By dividing the positioning device into fixed and movable segments, the design enables rapid lens replacement. The movable part can be independently shifted to unlock the lens from the frame, allowing users to quickly remove and replace lenses without time-consuming disassembly procedures.

AI summary
The invention relates to a goggle lens replacement structure. The lens assembly hole includes a limiting convex portion protruding on one side, and an embedding convex portion protruding on the other side of the spectacle frame. The spectacle lens is arranged in the lens assembly hole. The spectacle lens includes an embedded hole provided on one side corresponding to the limiting convex portion, and a fitting portion arranged on the other side thereof. The positioning device is combined and fixed with the fitting portion. The positioning device has a slotted hole disposed thereon corresponding to the embedding convex portion, and a movable element movable in the slotted hole, so that the movable element can be pushed by a user to move in the slotted hole. The movable element has an embedding protrusion protrudes formed a side thereof toward the outside of the slotted hole, corresponding to the embedding convex portion.
