Modular Goggle Frame with Pivoting Fasteners for Tool-Free Lens Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional goggles lack versatility in accommodating wearers with parallax vision, as they typically come with fixed diopter lenses, limiting clear vision during swimming and sun protection, and do not allow for easy lens replacement without tools.
Innovation Solution
A pair of goggles with a modular design featuring a main frame body, secondary frame body, soft frame body, and fasteners that allow for tool-free lens replacement and assembly, ensuring secure fixation of lenses within the soft frame body using recesses and fastening holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If goggles have fixed diopter lenses, then manufacturing is simple and cost is low, but versatility for different vision needs is poor
Solution Approach 1:
The goggles are divided into separate modular components: a main frame body, a secondary frame body, and replaceable lens assemblies. This segmentation allows different lens assemblies with various diopters to be interchangeably mounted on the same goggles frame, providing versatility without requiring multiple complete goggle sets.
Solution Approach 2:
The main frame body and secondary frame body are designed with universal mounting structures (recesses and fastening holes) that can accommodate multiple types of lens assemblies. This multi-functionality allows a single goggles frame to serve multiple vision correction needs through lens replacement.
2Ease of operation
If goggles allow easy lens replacement, then user convenience is improved, but device complexity increases
Solution Approach 1:
The lens assembly is segmented from the main goggle structure through the secondary frame body, which can be easily detached. The fastening mechanism uses simple holes and pivoting actions rather than complex fasteners, enabling users to replace lenses without tools while maintaining reasonable structural integrity.
Solution Approach 2:
The fastening mechanism incorporates dynamic elements that allow easy opening and closing. The fastener can pivot to release the secondary frame body from the main frame body, and the recesses provide flexible positioning during assembly, making lens replacement simple while the locked state ensures secure fixation during use.
3Reliability
If goggles have secure lens fixation, then lens stability is improved, but ease of lens replacement deteriorates
Solution Approach 1:
The main frame body and secondary frame body are pre-formed with recesses that guide and hold the lens assembly in the correct position during assembly. This preliminary structural preparation ensures proper alignment and secure fixation is achieved automatically when the fastener is closed, without requiring complex alignment procedures or tools.
Solution Approach 2:
The fastening system transitions from a dynamic open state (allowing easy insertion and removal) to a static locked state (providing secure fixation during swimming). The fastener pivots to engage the holes, creating a stable connection that maintains lens security while allowing quick release when needed.

AI summary
Provided is a pair of goggles with replaceable lenses, including a main frame body, at least one lens, a secondary frame body, a soft frame body and at least one fastener. The at least one fastener is pivoted when the at least one lens is replaced. The main frame body and the secondary frame body are separated such that the at least one lens is removed. Moreover, when the at least one lens is assembled, the main frame body and the secondary frame body are respectively provided with a pair of grooves, the pair of grooves holds and fix the soft frame body, and the main frame body and the secondary frame body are held by the at least one fastener so that the at least one lens is fixed inside the soft frame body.
