Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional 3-D display systems are used, then three-dimensional visualization is achieved, but the user must wear glasses or additional wearable components that are problematic in surgical environments
Solution Approach 1:
The patent extracts the 3-D visualization capability from the wearable glasses and integrates it directly into the display system itself. The display system includes a housing with a display assembly that provides 3-D visualization without requiring external wearable components, thereby eliminating the conflict between achieving 3-D visualization and ease of use in sterile environments.
Solution Approach 2:
The patent merges the 3-D display functionality with the surgical robotic system console. The display assembly is integrated into the housing of the surgical robotic system, combining the control interface and visualization system into a unified structure that eliminates the need for separate wearable 3-D glasses.
2Loss of information
If 3-D display systems with wearable components are used, then three-dimensional images can be visualized, but the device complexity increases
Solution Approach 1:
The patent combines the 3-D display functionality directly into the surgical robotic system console housing. The display assembly with its housing, light sources, and optical elements is integrated as a unified structure, eliminating the need for separate wearable 3-D glass systems and reducing overall device complexity.
3Adaptability or versatility
If the display system requires manual adjustment, then the spatial relationship can be customized, but the ease of operation decreases
Solution Approach 1:
The patent implements automatic adjustment mechanisms that detect the user's eye position and head orientation, and autonomously adjust the display parameters including spatial relationship, magnification, and illumination. This self-adjusting capability eliminates manual intervention while maintaining optimal visualization conditions, thereby improving ease of operation without sacrificing adaptability.
Solution Approach 2:
The display system incorporates sensors that detect user eye position and head orientation, providing feedback to the control system. Based on this feedback, the system automatically adjusts display parameters to maintain optimal spatial relationship and visualization quality, eliminating the need for manual adjustment while preserving adaptability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides optimal visualization of three-dimensional images without the need for additional wearable components, enhancing user control and safety during robotic surgery by automatically adjusting the display and potentially pausing surgical operations if the user's gaze is diverted.
Implementation Method 1
a first sensor assembly and a second sensor assembly. The first sensor assembly and the second sensor assembly can be coupled to or integrally formed with the display. The display system can include a processor or controller configured to detect and track an eye position or a head position of a user relative to the display based on processing output data of the first sensor assembly
Implementation Method 2
The processor or controller also can be configured to detect and track a gaze of the user based on processing output data of the second sensor assembly

AI summary
An autostereoscopic three-dimensional display system for surgical robotics has an autostereoscopic three-dimensional display configured to receive and display video from a surgical robotics camera, and a first sensor assembly and a second sensor assembly. A processor is configured to detect and track an eye position or a head position of a user relative to the display based on processing output data of the first sensor assembly, and to detect and track a gaze of the user based on processing output data of the second sensor assembly. The processor further is configured to modify or control an operation of the display system based on the detected gaze of the user. A spatial relationship of the display also can be automatically adjusted in relation to the user based on the detected eye or head position of the user to optimize the user's visualization of three-dimensional images on the display.
