Solution Overview

Problem

Conventional goggle lens systems for motorsports are difficult to manipulate, prone to dirt and debris accumulation, and suffer from distortion and accidental removal of tear-off films, leading to impaired vision and potential damage.

Innovation Solution

A sequentially-stacked, pre-curved removable lens system with a finger-tab and a goggle frame featuring a lens track and anti-slip headstrap, which allows for individual removal of lenses and prevents distortion by fusing the main lens with the tear-off stack, and using breathable foam and vent ports to manage moisture.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If flat tear-off films are manually secured onto a curved main lens, then the tear-off system can be attached to the goggle, but the user's vision becomes distorted and impaired

Engineering Contradiction:

Improveease of attaching tear-off filmsVSAvoidvision clarity

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The patent applies curvature to the tear-off films to match the curved main lens surface. The tear-off films are pre-curved to conform to the spherical/curved shape of the main lens, eliminating the flat-to-curved mismatch that causes vision distortion. This allows the tear-off system to be properly attached while maintaining clear, undistorted vision for the user.

Inventive Principle:

Principle #14Spheroidality (Curvature)

2Ease of operation

If individual tabs are folded in an alternating way to enable single layer removal, then sequential removal is possible, but the user may accidentally grab and remove the entire stack

Engineering Contradiction:

Improvesequential removal capabilityVSAvoidaccidental removal prevention

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent segments the tab structure into individual non-alternating tabs for each tear-off layer. Each layer has its own dedicated tab that is not folded alternately with adjacent layers, creating independent access points. This segmentation allows users to reliably grab and remove only the intended single layer without accidentally catching adjacent layers, while still enabling sequential removal of all layers as needed.

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If tear-off films are stacked and secured onto the main lens, then multiple lens options are available, but moisture, dust, sand, mud and debris can collect between the films and main lens

Engineering Contradiction:

Improvemultiple lens optionsVSAvoiddebris accumulation

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

Inventive Principle:

Principle #14Spheroidality (Curvature)

4Adaptability or versatility

If conventional goggle lenses are used in motorsports, then the goggles can be worn during activity, but the lenses become dirty and scratched and are difficult to manipulate

Engineering Contradiction:

Improveusage during motorsportsVSAvoidlens manipulation

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent implements a disposable tear-off lens system where multiple single-use tear-off films are stacked on the main lens. When the main lens becomes dirty or scratched during motorsports activity, users can quickly remove it by pulling the tab and replace it with a fresh tear-off film from the stack. This disposable approach eliminates the need for cleaning or complex manipulation of permanent lenses, allowing continuous use during high-intensity motorsports activities.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

AI summary

Removable goggle lens system including a sequentially-stacked set of lenses each of the lenses having a front-face, a back-face, a thickness, and a finger-tab. Each of the lenses are defined by the front-face, the back-face, the front-face, and the back-face separated by the thickness; and the finger-tab formed as an extension of the thickness such that a wearer-user can remove each of the lenses sequentially as desired approaching a main lens of a host goggle as sequentially removed.
