Interchangeable Goggle Lenses With Magnetic-Mechanical Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional goggles with interchangeable lenses often have complex or cumbersome mechanisms for lens removal, and existing magnetic attachments can lead to lens dislodgment, resulting in a less than ideal user experience.
Innovation Solution
A goggle design incorporating a magnetic and mechanical attachment mechanism, featuring a slider and retention member, which allows for easy and secure exchange of lenses using a spring-biased slider that translates between positions to facilitate lens ejection and attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a magnetic attachment mechanism is used to secure the lens to the frame, then the lens can be easily attached and detached, but the lens may be easily dislodged from the frame
Solution Approach 1:
The patent combines magnetic attachment elements with mechanical retention elements (lugs and slots) into a unified attachment mechanism. The magnetic elements provide initial attraction and easy attachment, while the mechanical lugs and slots provide positive retention and prevent dislodgment, resolving the contradiction between ease of operation and reliability.
Solution Approach 2:
The attachment mechanism uses a composite approach by integrating two different retention methods (magnetic and mechanical) into a single system. This composite mechanism leverages the advantages of both magnetic attraction (ease of attachment) and mechanical interlocking (secure retention) to simultaneously achieve ease of operation and reliability.
2Reliability
If a mechanical retention mechanism is used to secure the lens to the frame, then the lens can be securely retained, but the removal of the lens becomes complex or cumbersome
Solution Approach 1:
The mechanical retention mechanism is segmented into discrete lugs on the lens and corresponding slots on the frame. This segmentation allows the retention function to be distributed across multiple simple interaction points rather than a single complex mechanism, enabling secure retention while maintaining ease of operation through simple lateral movement.
Solution Approach 2:
The mechanical retention system is designed to be dynamic rather than fixed. The lugs can laterally move within the slots during attachment and detachment, allowing the mechanism to transition between locked and unlocked states easily. This dynamic design enables secure retention during use while facilitating simple removal when needed.
3Reliability
If multiple retention elements are used to prevent lens dislodgment, then the lens can be securely retained, but the device complexity increases
Solution Approach 1:
The retention system is segmented into multiple identical, simple lugs and slots distributed around the lens periphery. Rather than using a single complex retention mechanism, multiple simple elements work together to provide secure retention, reducing overall complexity while improving reliability through redundancy.
Solution Approach 2:
The lugs and slots serve multiple functions: they provide mechanical retention, guide lens alignment during attachment, and work in conjunction with the magnetic elements. This multi-functionality reduces the need for separate dedicated components, thereby reducing device complexity while maintaining reliable retention.
