Solution Overview

Problem

Existing ski goggles complicate the process of interchanging goggle lenses, especially at low temperatures, and require significant space for spare lenses, making it difficult to easily switch between different types such as amber, yellow tints, or polarized lenses.

Innovation Solution

The design incorporates a coupling arrangement with a removable nose bridge that serves as a coupling point, allowing for easy removal and replacement of the goggle lens, featuring notches and hooks that securely fit the lens perimeter, enabling simple interchange without the need for extensive lens border contact with the frame.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a conventional frame structure is used to secure the goggle lens, then the lens is securely held, but the lens interchange process becomes complicated and requires significant space for spare lenses

Engineering Contradiction:
Improvelens interchange processVSAvoidframe structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The nose bridge is separated from the main frame structure, creating an independent removable component. This segmentation allows the lens to be accessed and interchanged by removing only the nose bridge portion, rather than disassembling the entire frame, thereby simplifying the lens interchange process while maintaining structural integrity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The nose bridge is extracted as a separate functional element from the frame. By taking out this specific component that provides lens support and positioning, the design enables easy lens removal and replacement without requiring the entire frame to be opened or complicated mechanisms to be activated

Inventive Principle:
Principle #2Taking out (Extraction)

2Strength

If the nose bridge is made bulky to provide structural support, then the lens is securely mounted, but the overall goggle design becomes less comfortable and more cumbersome

Engineering Contradiction:
Improvelens mounting securityVSAvoidnose bridge
Core Design Contradiction:
StrengthVSWeight of moving object

Solution Approach 1:

The nose bridge is designed with localized structural features (hooks and notches) that provide concentrated support at critical points where the lens contacts the frame. This local reinforcement approach maintains strong lens mounting security while keeping the overall nose bridge structure lightweight and minimal, avoiding unnecessary bulk throughout the entire component

Inventive Principle:
Principle #3Local quality

3Strength

If the coupling arrangement requires extensive contact between the lens border and frame, then the lens is securely held, but the lens interchange process becomes more difficult and time-consuming

Engineering Contradiction:
Improvelens secure fitVSAvoidlens interchange time
Core Design Contradiction:
StrengthVSLoss of time

Solution Approach 1:

The nose bridge is pre-configured with hooks and notches that are positioned to automatically engage with the lens perimeter upon insertion. This preliminary arrangement of coupling features ensures that when the lens is installed, it is quickly and securely held without requiring extensive manual adjustment or prolonged contact during the interchange process

Inventive Principle:
Principle #10Preliminary action

AI summary

The invention refers to ski goggles (100) for a goggles wearer with a goggle frame (101), having a first side (101b) facing the goggles wearer's face during normal use and a second side (101a) facing away from the goggles wearer's face during normal use; with a nose bridge (133) being brought to rest on a goggles wearer's nose during normal use; with a goggle lens (103) having a first surface (103a) facing the goggles wearer's face during normal use and having a second surface (103b) facing away from the goggles wearer's face during normal use, the goggle lens (103) being constructed and arranged for looking through with both of the goggles wearer's eyes during normal use; with a frame pad (102) being connected to the goggle frame (101) and being brought to rest on the goggles wearer's face during normal use; with a retaining strap (104) holding the ski goggles (100) on the goggles wearer's head during normal use; with a coupling arrangement (130) being adapted to releasably couple the goggle lens (103) to the goggle frame (101), the coupling arrangement (130) comprising at least one first coupling point (131) disposed at a nose area (101d) of the first side (101b) of the goggle frame (101); and at least one second coupling point (132) disposed around at least a portion of a perimeter of the first side (101a) of the goggle frame (101). The invention is characterized in that the coupling arrangement (130) comprises the nose bridge (133), whereby the nose bridge (133) is releasably coupleable to the goggle frame (101) and whereby the nose bridge (133) provides the at least one first coupling point (131).
