Solution Overview

Problem

Conventional ski goggles restrict the field of view due to their thickness, which is necessary for ventilation to prevent misting but limits lateral and vertical vision.

Innovation Solution

The frame thickness is reduced to less than 1.5 cm, with ventilation openings between the goggle lens and frame pad to maintain stability and prevent misting, allowing the goggle lens to be closer to the eye for an increased viewing angle.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the frame thickness is increased to provide ventilation space, then the goggle lens can be ventilated to prevent misting, but the field of view is restricted laterally and vertically

Engineering Contradiction:
Improveprevention of lens mistingVSAvoidfield of view
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The frame is divided into multiple sections with ventilation openings distributed across different areas. The frame includes upper and lower ventilation openings that are segmented to provide adequate airflow while maintaining a thinner overall structure that doesn't restrict the field of view.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The frame incorporates porous or perforated structures with multiple ventilation openings that allow air to pass through. This porous design enables effective ventilation and misting prevention while using less material and creating a thinner frame profile that expands the visible field.

Inventive Principle:
Principle #31Porous materials

2Area of stationary object

If the frame thickness is reduced to expand the field of view, then the viewing angle is increased, but the ventilation capability may be compromised

Engineering Contradiction:
Improvefield of viewVSAvoidventilation effectiveness
Core Design Contradiction:
Area of stationary objectVSReliability

Solution Approach 1:

Instead of relying solely on increasing frame thickness for ventilation, the design introduces ventilation openings in multiple dimensional orientations - upper, lower, and lateral openings that create three-dimensional airflow paths. This multi-dimensional approach provides effective ventilation even with a reduced frame thickness.

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

Solution Approach 2:

The frame structure is designed to serve multiple functions simultaneously: it provides structural support, enables ventilation through integrated openings, and maintains aesthetic appearance. The ventilation openings are strategically positioned to fulfill both functional and design requirements without requiring excessive frame thickness.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If the goggle lens is positioned closer to the eye, then the viewing angle is increased, but the frame must be thinner to accommodate this positioning

Engineering Contradiction:
Improveviewing angleVSAvoidframe thickness
Core Design Contradiction:
Ease of operationVSLength of stationary object

Solution Approach 1:

The design changes the geometric parameters of the frame, specifically reducing the thickness parameter while adjusting the positioning of the goggle lens closer to the eye. This parameter optimization allows the lens to be positioned at an optimal distance for maximum viewing angle while maintaining sufficient frame thickness for structural integrity and ventilation.

Inventive Principle:
Principle #35Parameter changes

AI summary

Ski goggles for a goggles wearer have a frame and a goggle lens supported by the frame. The goggle lens has a surface facing the wearer's face during normal use and has a surface facing away from the wearer's face. A frame pad is connected to the frame and is seated on the wearer's face during normal use. A retaining strap holds the ski goggles on the wearer's head during normal use. The frame has a thickness (d1, d2) of less than 1.5 centimeters in a perpendicular direction to the surface of the lens facing the wearer's face during normal use.
