Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Face shields often cause eyewear to fog up and prescription glasses to shift, requiring removal of the face shield to address these issues, which compromises protection and convenience.

Innovation Solution

Incorporating eyewear attachment elements and movement elements into face shields that allow eyewear to be adjusted or moved without removing the face shield, including swivel and hinge mechanisms for positioning lenses relative to the solid barrier, enabling cleaning and repositioning without compromising protection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If eyewear is worn with face shields, then vision augmentation is achieved, but condensation accumulates on lenses causing fogging

Engineering Contradiction:

Improvevision clarityVSAvoidcondensation fogging

Core Design Contradiction:

Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The patent divides the eyewear system into separable components: the face shield remains on the user while the eyewear can be detached and reattached. The attachment mechanism allows the eyewear to be separated from the face shield temporarily to prevent condensation accumulation, then reattached when needed. This segmentation enables independent management of the two components to avoid their harmful interaction.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary attachment mechanism (such as clips, hooks, or magnetic elements) that connects the eyewear to the face shield. This intermediary allows the eyewear to be securely held in position when needed, yet easily removed to prevent fogging. The intermediary component mediates between the need for vision augmentation and the need to prevent condensation buildup.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If eyewear is worn with face shields, then vision correction is achieved, but glasses shift out of position resulting in blurry vision

Engineering Contradiction:

Improvevision correction accuracyVSAvoidglasses position stability

Core Design Contradiction:

Measurement precisionVSStability of the object's composition

Solution Approach 1:

The patent implements a dynamic attachment system where the eyewear can be easily adjusted and repositioned while maintaining secure attachment. The attachment mechanism allows for quick adjustments to restore proper positioning if the glasses shift, enabling the user to maintain vision correction accuracy throughout use of the face shield.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent incorporates preliminary positioning features in the attachment mechanism that guide the eyewear into the correct position during attachment. This preliminary alignment ensures that when the eyewear is attached to the face shield, it is automatically positioned correctly for optimal vision correction, preventing shift-related blurriness.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If face shield is removed to clean or adjust eyewear, then eyewear maintenance is achieved, but protection integrity is compromised

Engineering Contradiction:

Improveeyewear maintenanceVSAvoidprotection integrity

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent allows segmentation of the protective system by enabling independent removal of the eyewear from the face shield. Users can maintain and clean the eyewear separately while the face shield remains in place, preserving continuous protection. The attachment mechanism facilitates this selective separation without requiring removal of the entire protective assembly.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent ensures continuity of protection by allowing rapid reattachment of the eyewear after brief maintenance. The attachment mechanism is designed for quick connection, minimizing the time the protective system is incomplete. This enables continuous useful action of protection while allowing necessary maintenance intervals.

Inventive Principle:

Principle #20Continuity of useful action

4Ease of operation

If face shield is removed for eyewear adjustment, then eyewear positioning is achieved, but protection is compromised requiring waiting in uncompromised situation

Engineering Contradiction:

Improveeyewear adjustmentVSAvoidprotection interruption time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent implements a dynamic, easily adjustable attachment system that allows quick repositioning of the eyewear while the face shield remains on the user. The mechanism enables rapid adjustment without full removal, minimizing protection interruption time while maintaining ease of operation for positioning corrections.

Inventive Principle:

Principle #15Dynamics
