Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing interchangeable lens systems for snowsports goggles are difficult to use quickly, especially with gloved or numb hands, and often compromise aesthetics due to clip placement over the lens.

Innovation Solution

A goggle design featuring magnetic elements for lens attachment, with tongues and movable clips that allow for easy lens swapping by pushing inward, eliminating the need for pulling and reducing bulk, while maintaining a streamlined appearance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If clips are placed over the lens to retain it, then the lens is securely held, but the aesthetic appeal is reduced and the clip is difficult to operate with gloved hands

Engineering Contradiction:

Improvelens retention securityVSAvoidclip operation difficulty

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The clip mechanism is extracted from the lens surface and relocated to the rear of the lens assembly. The clip now engages with a tab on the rear side rather than overlaying the lens, eliminating the aesthetic compromise and improving operability with gloved hands while maintaining secure retention through the same clipping action.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The clipping mechanism transitions from a lateral engagement (side-to-side) to a longitudinal engagement (front-to-back). The tab extends rearward from the lens, and the clip engages this tab from the rear, moving the interaction to a different spatial dimension that improves accessibility and aesthetics.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Reliability

If clips are placed over the lens to retain it, then the lens is securely held, but the external appearance is complicated

Engineering Contradiction:

Improvelens retention securityVSAvoidaesthetic appearance

Core Design Contradiction:

ReliabilityVSShape

Solution Approach 1:

The clip is extracted from the visible lens surface and positioned on the rear side of the lens assembly. This relocation removes the visual complication from the external appearance while preserving the mechanical function of secure retention through rear-side engagement with the tab.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The retention mechanism is moved to the rear dimension of the lens assembly. The tab extends backward and the clip engages it from the rear, placing the mechanical interaction in a dimension that does not compromise the aesthetic appearance of the lens front surface.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Productivity

If a pulling motion is required to move the clip away from the lens, then the lens can be detached, but it is difficult to get a grip on the small clip with gloved or numb hands

Engineering Contradiction:

Improvelens swapping speedVSAvoidgrip difficulty

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The operational direction is inverted from pulling to pushing. Instead of requiring the user to pull the clip away from the lens (which requires gripping a small feature), the user pushes the tab forward, causing the clip to disengage naturally. This reversal of motion direction greatly improves operability with gloved or numb hands.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The tab is pre-positioned to extend rearward with the clip already in place. This preliminary arrangement allows the user to simply push the tab forward to initiate detachment, eliminating the need for complex gripping and pulling actions. The structure is prepared in advance to enable simple push-based operation.

Inventive Principle:

Principle #10Preliminary action

AI summary

A goggle for use in snowsports comprises a body (14) and a detachable lens assembly (12), magnets or magnetic elements being provided on the lens assembly (12) and magnets or magnetic elements being provided in corresponding positions on the body (14), for detachably holding the lens assembly (12) to the body (14), at least one tongue (34) extending from the rear surface (36) of the lens assembly (12) on each lateral side (18, 54) of the lens assembly (12), each tongue (34) extending in a direction substantially behind the lens assembly (12), into the body (14) when the lens assembly (12) is fitted to the body (14), and an aperture (42, 66) extending through each tongue (34), and at least one moveable clip (72) being provided on each lateral side (18, 54) of the body (14), each clip (72) being movable between a released position and an engaged position, each clip (72) including a retaining finger (82) which in the engaged position passes into the aperture (42, 66) in the tongue (34), preventing detachment of the lens assembly (12) from the frame and in the released position moves clear of the tongue (34), allowing detachment of the lens assembly (12).
