Multi-Thickness Goggle Lens Segmentation for Frame Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sport goggles are limited by compatibility issues with lenses of different thicknesses, requiring new goggles if a user or manufacturer needs a lens of a different thickness, which restricts protection and versatility.
Innovation Solution
A multi-thickness lens design that includes a goggle lens perimeter portion and a viewing portion of different thicknesses, with attachment features allowing it to be retrofitted onto existing goggles, providing enhanced protection and compatibility with various goggle frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a single thickness lens is used, then the lens is compatible with standard goggle frames, but the protection against debris is insufficient
Solution Approach 1:
The lens is segmented into two distinct thickness zones: a thicker perimeter portion (first thickness) for enhanced protection and a thinner viewing portion (second thickness) for compatibility with standard goggle frames. This segmentation allows each region to fulfill its specific function independently, resolving the contradiction between protection and compatibility.
Solution Approach 2:
Different regions of the lens are assigned different thickness qualities tailored to their specific functions. The perimeter portion has a first thickness optimized for debris protection, while the viewing portion has a second thickness optimized for frame compatibility and optical performance. This local differentiation resolves the contradiction by applying the right thickness in the right location.
2Object-affected harmful factors
If a thicker lens is used for better protection, then debris protection is improved, but compatibility with existing goggle frames is lost
Solution Approach 1:
The lens divides its thickness profile into segments: a thicker first portion at the perimeter for protection and a thinner second portion at the viewing area for frame compatibility. This segmentation enables the lens to provide enhanced protection where needed while maintaining compatibility with existing frames where required.
Solution Approach 2:
The lens implements local quality variation by making the perimeter portion thicker than the viewing portion. This local thickness differentiation allows the lens to provide superior protection at the perimeter while maintaining the thin profile needed for compatibility with standard goggle frames.
3Adaptability or versatility
If a thinner lens is used for frame compatibility, then compatibility with goggle frames is maintained, but protection against debris is reduced
Solution Approach 1:
The lens segments its structure into a thinner viewing portion for frame compatibility and a thicker perimeter portion for debris protection. This segmentation ensures that the thin profile required for frame compatibility is maintained in the viewing area while the perimeter provides enhanced protection.
Solution Approach 2:
The lens applies local quality by making the viewing portion thinner for frame compatibility while the perimeter portion is thicker for protection. This local differentiation resolves the contradiction by optimizing each region's thickness for its specific function.

AI summary
A multi-thickness lens for a goggle may be disclosed in accordance with various embodiments. The multi-thickness lens may include a portion of a first thickness and a portion of a second thickness. In particular, the multi-thickness lens may be inserted into a goggle, including goggles configured to receive standard lenses. Further, the goggle may include features that may allow the multi-thickness lens to distribute forces and/or stresses to the goggle and/or may include features and/or components adapting the goggle to receive a multi-thickness lens.
