Protective Eyewear With 3D Downward Viewing for Ergonomic Posture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective eyewear for medical and dental professionals fails to allow users to maintain ideal ergonomic posture while providing clear vision of working areas below the horizontal plane, often requiring excessive neck, back, and eye strain, and lacks accurate three-dimensional depth perception.
Innovation Solution
Eyewear equipped with adjustable cameras and video display devices positioned to provide three-dimensional views with natural depth perception, allowing users to maintain ergonomic posture by adjusting the eyewear declination angle to match the working declination angle, and incorporating image and audio processing technologies for enhanced functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional protective eyewear is used, then eye protection is provided, but users experience excessive neck, back, and eye strain when viewing working areas below the horizontal plane
Solution Approach 1:
The patent introduces a new dimension by integrating a camera system that captures images from below the horizontal plane and displays them on a screen positioned at a comfortable viewing angle. This transforms the viewing experience from direct downward gaze to viewing a displayed image, eliminating neck and back strain while maintaining eye protection.
Solution Approach 2:
The camera and display screen act as intermediaries between the user's eyes and the working area below the horizontal plane. Instead of directly viewing the working area, users view images captured by the camera, which mediates the viewing process and eliminates the need for excessive eye tilt and head bending.
2Ease of operation
If magnification eye pieces with eyewear declination angle are used, then some neck and back strain is reduced, but accurate three-dimensional depth perception is lost and eye strain remains
Solution Approach 1:
The camera creates a visual copy of the working area below the horizontal plane and displays it on a screen. This copy preserves the three-dimensional spatial relationships and depth information of the original scene, allowing users to maintain accurate depth perception while viewing from a comfortable position.
Solution Approach 2:
The patent employs color or stereoscopic display technology on the screen to convey depth information. By using color cues or stereoscopic imaging, the display maintains accurate three-dimensional depth perception, allowing users to judge distances and spatial relationships correctly without direct viewing of the working area.
3Ease of operation
If the eyewear declination angle is increased to match working declination angle, then ergonomic posture is improved, but the structure of the eyewear becomes more complex
Solution Approach 1:
The patent divides the viewing system into separate functional components: a camera module positioned to capture images from below the horizontal plane, and a display screen positioned at a comfortable viewing angle. This segmentation allows each component to be optimized independently, with the camera positioned for ergonomic viewing while the screen provides comfortable image display, without requiring complex angular adjustments to the entire eyewear structure.

AI summary
Using a camera pointing downward, a working area below eye level can be displayed by a headwear for users, so that the user can maintain healthy sitting or standing posture while working on patients or objects located below eye level. Using two or more cameras pointing downward, three-dimensional views with accurate and natural depth perception of a working area can be displayed by a headwear for users. 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 associated with the headwear. The headwear 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. Contactless control devices can be used to control the functions of the headwear.
