Solution Overview

Problem

Existing personal protective devices for the eyes, such as visors, hinder the use of optical instruments and prescription glasses, reducing user comfort and operational flexibility, and require removal in contaminated environments for instrument use.

Innovation Solution

A protective visor with recesses for viewing and amplification instruments and recesses for prescription lenses, made of transparent material, allowing easy use of optical instruments and glasses without removing the device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a protective visor is designed to provide full facial protection, then protection effectiveness is improved, but the ability to use optical instruments is worsened

Engineering Contradiction:

Improveprotection effectivenessVSAvoidability to use optical instruments

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The visor is divided into multiple functional zones: an upper protective portion for facial protection and a lower recessed portion for optical instrument placement. This segmentation allows the visor to simultaneously provide protection while creating a dedicated space for instruments without compromising either function.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The recessed portion of the visor is designed to receive and hold optical instruments within its structure. The instruments are nested within the visor's lower portion, allowing them to be integrated into the protective device without requiring separate wear or handling.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Ease of operation

If a protective device is designed to be compact, then ease of operation is improved, but the ability to accommodate prescription glasses is worsened

Engineering Contradiction:

ImprovemobilityVSAvoidaccommodation of prescription glasses

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The visor features a localized recessed portion specifically designed to accommodate optical instruments and prescription glasses. This local modification creates a dedicated space without requiring the entire visor to be enlarged, thus maintaining compactness while providing specific accommodation for glasses.

Inventive Principle:

Principle #3Local quality

3Reliability

If a protective device is designed with fixed positioning, then protection effectiveness is improved, but the ability to adjust eyeglasses is worsened

Engineering Contradiction:

Improveprotection effectivenessVSAvoidadjustability of eyeglasses

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The recessed portion of the visor is designed with flexibility to accommodate different positions and orientations of optical instruments and prescription glasses. This dynamic design allows for adjustment while the overall visor structure remains fixed to provide consistent protection.

Inventive Principle:

Principle #15Dynamics
