Solution Overview

Problem

Current protective eyewear for medical and surgical professionals fails to allow users to maintain ideal ergonomic posture while working below the horizontal plane, often requiring uncomfortable bending and straining, and lacks accurate three-dimensional vision and depth perception.

Innovation Solution

The development of eyewear with two or more cameras and video display devices, along with audio and lighting components, that adjust to provide three-dimensional video images with natural depth perception, allowing users to maintain ergonomic posture and perform tasks from their trained positions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional protective eyewear is used, then eye protection is provided, but the user must bend head and neck and strain eyes to view working areas below eye level

Engineering Contradiction:
Improveviewing comfortVSAvoideye strain and neck strain
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a video display dimension that overlays working area images onto the user's field of view. Cameras capture images of the working area below eye level and display them on transparent displays positioned in the user's line of sight, eliminating the need for downward eye tilt and head bending while maintaining ergonomic posture.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent uses video displays and cameras as intermediary devices between the working area and the user's eyes. The cameras capture light from the working area and the displays present this information in a position that does not require the user to strain their neck or eyes, acting as a mediator that transforms the viewing geometry.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If magnification eye pieces with eyewear declination angle are used, then neck and back bending is reduced, but accurate three-dimensional vision and depth perception are lost

Engineering Contradiction:
Improveergonomic postureVSAvoiddepth perception accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent creates visual copies of the working area using cameras and displays the copied images on transparent displays. Multiple cameras capture images from different positions and the system reconstructs three-dimensional spatial relationships in the displayed images, preserving depth perception while allowing the user to maintain ergonomic posture by viewing the copied images in front of them rather than looking down at the actual working area.

Inventive Principle:
Principle #26Copying

AI summary

Using two or more cameras attached to the eyewear, three-dimensional views with accurate and natural depth perception of the working area can be displayed for users, so that the user can maintain healthy sitting or standing posture while working on patients or objects located below horizontal eye level. Additional functions including eye protection, zoom-in, zoom-out, on-off, lighting control, overlapping, and teleconference capabilities are also supported using electronic, video and audio devices attached to the eyewear. The eyewear can also comprise a face shield designed to protect the user from hazardous droplets, aerosols, harmful wavelengths of light, heat, sparks, flash burn, debris and/or flying objects.
