Autostereoscopic Surgeon Console With Head Bar for Glasses-Free 3D Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical robotic systems require operators to wear cumbersome polarized glasses or headgear for stereoscopic viewing, which obstruct peripheral vision, decrease light intensity, and cause ergonomic discomfort.
Innovation Solution
A surgical robotic surgeon console with an autostereoscopic display, a horizontal member, and a moveable head bar that supports the operator's head, allowing for ergonomic positioning and unobstructed peripheral vision without additional eyewear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If polarized glasses or headgear are used for stereoscopic viewing, then 3D visualization is achieved, but peripheral vision is obscured and ergonomic comfort deteriorates
Solution Approach 1:
The patent removes the requirement for polarized glasses or headgear by extracting the stereoscopic viewing function from wearable accessories and integrating it directly into the display system through autostereoscopic technology and head tracking sensors
Solution Approach 2:
The patent introduces head tracking sensors and software processing as intermediaries between the display and the user's eyes, enabling the display to dynamically adjust and direct appropriate images to each eye without requiring physical filters or headgear
2Measurement precision
If polarized filtering is used to enable stereoscopic viewing, then 3D image separation is achieved, but light intensity decreases and effective resolution is reduced
Solution Approach 1:
The patent replaces the mechanical/optical filtering system (polarized lenses) with an electronic control system that uses head tracking sensors and software to dynamically direct images to each eye, eliminating light loss from filtering
Solution Approach 2:
The patent changes the approach from passive optical filtering to active electronic control, where the display system dynamically adjusts image delivery based on real-time head position data, maintaining full light intensity while achieving stereoscopic separation
3Measurement precision
If the operator leans into a microscope-style viewer, then stereoscopic viewing is achieved, but peripheral vision is restricted and ergonomic comfort deteriorates
Solution Approach 1:
The patent transitions from a fixed microscope-style viewing geometry to a dynamic system where the display adapts to the user's head position in three-dimensional space, allowing the user to maintain a normal seated position while achieving stereoscopic viewing
Solution Approach 2:
The patent introduces head tracking sensors and software processing as intermediaries that enable the display to follow and adapt to natural head movements, eliminating the need to lean into a fixed viewer while maintaining stereoscopic效果
