Swimming Goggles with Glass Lens Insert
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Swimming goggles often suffer from reduced durability due to loss of elasticity in straps, breakdown of seals, and scratching of lenses over time.
Innovation Solution
Integration of a glass insert within the goggle lens, secured by an adhesive sheet, provides superior scratch resistance and protection for the underlying substrate and coatings, with the glass insert optionally installed over a mirror coating or other coatings on the substrate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional lens materials are used in swimming goggles, then the goggles are easier to manufacture and less expensive, but the lenses become scratched and wear out over time
Solution Approach 1:
The patent applies composite materials by combining a glass insert with the existing goggle lens substrate. The glass insert is positioned within a recess in the lens and secured with adhesive, creating a composite structure that leverages the scratch resistance of glass while maintaining the optical properties and manufacturing benefits of the original lens material. This resolves the contradiction by achieving enhanced durability through material composition rather than replacing the entire lens system.
2Reliability
If glass inserts are integrated into goggle lenses to improve scratch resistance, then lens durability is enhanced, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the lens system into distinct functional components: the original goggle lens substrate and a separate glass insert. The glass insert is placed within a recess in the lens, creating a segmented structure where each component serves a specific purpose. This segmentation allows the glass to provide scratch resistance while the substrate maintains optical properties, and the modular design facilitates easier manufacturing and assembly compared to creating a completely new lens structure.
Solution Approach 2:
The patent applies the nesting principle by placing the glass insert within a recess in the goggle lens, creating a nested structure where the glass element is housed within the larger lens assembly. The glass insert fits into the recess and is secured with adhesive, forming a compact integrated unit. This nesting approach minimizes the increase in device complexity by efficiently utilizing the existing lens space rather than adding external components.
3Duration of action of stationary object
If glass inserts are used to protect the substrate and coatings, then the lifespan of the goggles is extended, but the manufacturing process becomes more complex
Solution Approach 1:
The patent applies preliminary action by pre-forming a recess in the goggle lens substrate before final assembly. This recess is specifically designed to accommodate the glass insert, allowing for precise positioning and alignment during assembly. The preliminary preparation of the lens structure simplifies the overall manufacturing process by establishing proper fit and alignment features early in production, rather than requiring complex adjustments during final assembly.
Solution Approach 2:
The patent applies the intermediary principle by using an adhesive as a mediator between the glass insert and the goggle lens substrate. The adhesive is applied to the glass insert and positioned within the recess, creating a bonding interface that secures the glass in place. This intermediary material simplifies the assembly process by providing a straightforward bonding mechanism rather than requiring mechanical fasteners or complex joining methods, thus extending goggle lifespan while maintaining manufacturing efficiency.
