Detachable Goggle Lens System with Movable Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional goggles with fixed lenses limit versatility, as they cannot be easily changed to suit different environmental conditions or aesthetic preferences, and replacing damaged lenses requires purchasing a new pair.
Innovation Solution
A detachable goggle lens system that includes a lens rim, lens element, and engagement members allowing quick and easy interchange with a goggle frame, enabling users to swap lenses based on environmental conditions or aesthetics, and facilitating replacement of damaged lenses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If lenses are fixed to the goggle frame, then the structural integrity and stability of the goggle is improved, but the adaptability and ease of lens interchange deteriorates
Solution Approach 1:
The goggle system is divided into separate modular components: a frame and interchangeable lenses. The lens engagement members are segmented into a fixed portion on the frame and a movable portion on the lens, allowing the lens to be detached and replaced while maintaining structural integrity when engaged.
Solution Approach 2:
The lens engagement members incorporate dynamic elements, specifically movable portions that can transition between engaged and disengaged states. This dynamic mechanism allows the lens to be securely fixed during use while enabling easy interchange when needed, resolving the contradiction between stability and adaptability.
2Reliability
If lenses are fixed to the goggle frame, then the reliability of the goggle structure is improved, but the ease of operation for lens replacement deteriorates
Solution Approach 1:
The lens replacement function is extracted from the frame structure itself and implemented through separate engagement members. The movable portion of the engagement member can be manually actuated to release the lens from the frame, allowing easy lens replacement while maintaining reliable structural connection during normal use.
3Adaptability or versatility
If a detachable lens system is implemented, then the adaptability and ease of lens interchange is improved, but the device complexity increases
Solution Approach 1:
The engagement and disengagement functions are merged into a single mechanical interaction between the lens engagement members. The movable portion integrates both the locking and releasing functions, simplifying the overall mechanism while enabling adaptable lens interchange.
4Ease of operation
If a detachable lens system is implemented, then the ease of operation for lens swapping is improved, but the loss of time for engagement and disengagement occurs
Solution Approach 1:
The engagement members are pre-configured in their respective positions on the frame and lens. The movable portion is designed to be readily accessible and require minimal movement to transition between engaged and disengaged states, reducing the time required for lens replacement while maintaining ease of operation.

AI summary
A goggle lens is configured for use with a goggle frame having a frame body and a pair of frame engagement members positioned at respective lateral end portions of the frame body. The goggle lens includes a lens rim, and a lens element that is transparent to allow a user to view through the lens element. A pair of lens engagement members are coupled to respective lateral end portions of the lens rim. The pair of lens engagement members are selectively engageable with respective ones of the pair of frame engagement members. The pair of lens engagement members include a locking lens engagement member comprising a first element coupled to the lens rim, and a second element moveably coupled to the first element for facilitating selective engagement and disengagement with the respective one of the pair of frame engagement members.
