Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing helmets and face shields require cumbersome and imprecise adjustment methods, often necessitating removal from the wearer to achieve a comfortable and performance-optimal fit, leading to inconsistent and time-consuming fitting processes.

Innovation Solution

A face shield fit adjustment system with a frame and slider mechanism that allows for precise adjustment of the face shield relative to the wearer's eyes, enabling micro-adjustments without removing the helmet, using a channel and release mechanism for secure positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the face shield is adjusted using existing methods, then the fit can be modified, but the adjustment process is cumbersome and requires removal from the wearer

Engineering Contradiction:

Improveease of adjustmentVSAvoidtime for fitting process

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The face shield adjustment system transforms a static fixed-position face shield into a dynamic adjustable system. The slider mechanism allows the face shield to move along the longitudinal axis between multiple secured positions, enabling adjustment without removal and reducing fitting time while maintaining ease of operation.

Inventive Principle:

Principle #15Dynamics

2Measurement precision

If the face shield is adjusted using existing methods, then the fit can be modified, but the adjustment is imprecise

Engineering Contradiction:

Improveprecision of adjustmentVSAvoidsimplicity of adjustment

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The adjustment system divides the continuous adjustment range into discrete secured positions along the longitudinal axis. The slider can be positioned at multiple predetermined locations, providing precise control over the face shield distance from the wearer's eyes while maintaining operational simplicity through the release mechanism.

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If the face shield is made adjustable, then the fit can be optimized for performance, but the device complexity increases

Engineering Contradiction:

Improveadaptability of fitVSAvoidcomplexity of adjustment system

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The slider acts as an intermediary component between the face shield and the helmet frame. It provides the adjustment functionality through a simple mechanical interface that moves along the longitudinal axis, enabling adaptability of fit while minimizing device complexity through a straightforward slider-and-channel mechanism.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A face shield adjustment system is provided. A helmet and face shield can be attached such that the face shield is in an as-worn position. The face shield can be moved between a first secured position at a first distance from the eyes of the wearer in an as-worn position and a second secured position at a second distance from the eyes of the wearer in the as-worn position. The secured positions can fix the face shield relative to the eyes of the wearer and/or the helmet by an engagement between teeth of a helmet frame and teeth of a slider, where the slider is attached to the face shield.
