Ergonomic Eyewear with 3D Camera Display for Surgical Posture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical and surgical professionals face ergonomic challenges when working below the horizontal plane due to limitations in existing eyewear, which often require uncomfortable postures, strain, and inadequate three-dimensional vision, hindering precise hand-eye coordination.
Innovation Solution
The development of eyewear equipped with two cameras and video display devices positioned to provide three-dimensional video images with adjustable declination angles, allowing professionals to maintain healthy posture and operate from trained positions while offering additional features like zoom, lighting control, and audio processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional protective eyewear is used, then eye protection is provided, but the user must bend head, neck, or back and use excessive downward eye tilt to view working area clearly
Solution Approach 1:
The patent introduces a new dimension by incorporating a display device that presents the working area view at a horizontal orientation, allowing the user to view the working area without bending or tilting. This transforms the viewing experience from a downward vertical angle to a horizontal plane, eliminating the need for uncomfortable posture adjustments.
Solution Approach 2:
The display device acts as an intermediary between the user's eyes and the working area. Instead of directly viewing the working area below eye level, the user views an image of the working area displayed at a comfortable horizontal orientation on the display device, which is positioned in front of the user.
2Ease of operation
If magnification eye pieces with eyewear declination angle are used, then less bending of neck and back is required, but the achievable eyewear declination angle is limited and downward eye strain still occurs
Solution Approach 1:
The patent uses a camera to capture the working area view and displays it on a display device positioned at a horizontal orientation in front of the user. This transforms the viewing experience from a downward vertical angle to a horizontal plane, eliminating the need for uncomfortable posture adjustments and eye strain.
Solution Approach 2:
The patent replaces the mechanical magnification eye pieces with an electronic system consisting of a camera and display device. This substitution allows for greater flexibility in achieving the desired viewing angle and eliminates the physical limitations of optical magnification systems.
3Ease of operation
If video image processing methods are used to invert and reverse images, then ergonomic posture can be maintained, but users need to spend time re-training and depth perception is lost
Solution Approach 1:
The patent applies different image processing treatments to different parts of the displayed image. The image is rotated to present the working area at a comfortable viewing angle, but the spatial relationships and depth information are preserved through appropriate rendering techniques, maintaining both ergonomics and depth perception.
Solution Approach 2:
The patent changes the orientation parameter of the displayed image from a downward vertical angle to a horizontal plane, making the view comfortable for ergonomic viewing. Additionally, the image is rendered with depth information preserved, allowing users to maintain familiar spatial awareness without retraining.

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.
