Solution Overview

Problem

Current solutions for correcting visual impairments during winter sports, such as contact lenses, Over The Glasses (OTG) ski goggles, and lens clips, face issues like discomfort, condensation, light filtration, and injury risk, limiting their effectiveness and safety.

Innovation Solution

A 3D lens holder integrated into ski goggles that positions optical lenses outside the minimal surface of the goggles' outer edge, creating a closed volume with the visor to reduce condensation and light filtration, allowing for a wider range of diopter corrections up to -10 and reducing injury risk by eliminating the need for separate glasses or clips.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If OTG ski goggles are used to accommodate glasses with optical correction lenses, then visual impairment correction is enabled, but condensation forms on both sides of the correction lens significantly limiting sight

Engineering Contradiction:
Improvevisual impairment correctionVSAvoidcondensation on correction lens
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent positions the corrective lens in a different spatial dimension relative to the eye, using a lens holder that extends the optical path. The lens is placed at an optimized vertex distance (10-20mm) from the eye, outside the minimal surface of the goggle, creating a three-dimensional optical configuration that prevents condensation while maintaining correction effectiveness

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent introduces a specialized lens holder as an intermediary component between the corrective lens and the goggle structure. This lens holder serves as a mediator that optimizes the position of the lens, maintains proper vertex distance, and prevents direct contact between the lens and goggle surfaces that would cause condensation

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If double visor ski goggles are used, then protection and light filtering are improved, but light is lost at each material transition reducing illumination to the eye

Engineering Contradiction:
Improveprotection and light filteringVSAvoidlight reaching the retina
Core Design Contradiction:
Object-affected harmful factorsVSIllumination intensity

Solution Approach 1:

The patent extracts the corrective lens function from the traditional double visor structure and positions it independently in a lens holder. This separation allows the corrective lens to be positioned optimally without adding another filtering layer, thereby reducing total light loss while maintaining protection and filtering capabilities of the original visors

Inventive Principle:
Principle #2Taking out (Extraction)

3Adaptability or versatility

If separate glasses are carried under OTG ski goggles for optical correction, then visual impairment is corrected, but injury risk increases due to frame and glass not being designed to absorb fall energy

Engineering Contradiction:
Improveoptical correctionVSAvoidinjury risk during fall
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent merges the corrective lens with the goggle structure by integrating it into a lens holder that is part of the goggle assembly. This combination creates a unified protective system where the lens is secured in a manner that can better withstand impact forces compared to separate spectacles, reducing injury risk while maintaining optical correction

Inventive Principle:
Principle #5Merging (Combining)

4Adaptability or versatility

If lens clips are inserted inside ski goggles for optical correction, then correction is enabled, but condensation forms on both sides of the corrective lens and vibrations occur if the clip is not rigidly attached

Engineering Contradiction:
Improveoptical correctionVSAvoidcondensation and vibrations
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a specialized lens holder as an intermediary component that properly positions and secures the corrective lens. This mediator structure provides stable mounting that prevents vibrations and creates appropriate spacing that prevents condensation, overcoming the limitations of simple lens clips

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The lens holder extends the optical system in three-dimensional space, positioning the lens at the correct vertex distance from the eye. This spatial configuration prevents condensation by maintaining proper airflow and spacing, while the rigid structure of the lens holder prevents vibrations that would occur with flexible clips

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

The present invention relates to a lens holder (100) for mounting or positioning, in a pair of goggles (such as ski goggles) suitable for winter sports, at least one optical lens (130, 140) for correcting visual impairment of a user. The outer edge of the lens holder (100) is designed to mount the lens holder in a closely fitting manner to the outer lens (310) of the pair of goggles suitable for winter sports. Furthermore the lens holder (100) is adapted for the mounting or positioning of at least one optical lens (130, 140). When the lens holder is mounted, at least one optical lens is positioned outside the minimal surface defined by the external edge of the lens holder. Furthermore at least one closed space is defined by the lens holder, the at least one optical lens (130, 140) and the outer lens (310) of the pair of goggles (such as ski goggles).
