Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional robotic systems are used for manual movement guidance, then automation is provided, but accuracy and precision of manual movement deteriorate
Solution Approach 1:
The patent introduces an augmented reality display as an intermediary between the robotic system and the operator. The display overlays virtual guidance indicators (such as target positions, movement paths, and orientation markers) onto the real-world view, providing precise movement guidance without requiring full automation. This mediator enables the operator to maintain manual control while receiving high-precision guidance feedback.
2Loss of information
If operators focus on guidance displays, then information accuracy improves, but attention to environment deteriorates
Solution Approach 1:
The patent transitions the guidance information from a separate 2D display plane to a spatially-aligned augmented reality dimension. By projecting guidance indicators directly into the operator's field of view and aligning them with the corresponding physical objects in 3D space, the system eliminates the need for the operator to shift attention between the display and the environment. The guidance information becomes part of the environmental context itself.
3Manufacturing precision
If detailed guidance information is provided, then movement precision improves, but device complexity deteriorates
Solution Approach 1:
The patent implements a multi-functional augmented reality display system that provides multiple types of guidance information simultaneously through a single interface. The display can show target positions, movement paths, orientation markers, and real-time feedback on a single augmented reality interface, eliminating the need for multiple separate displays, control panels, or guidance devices. This universal interface reduces overall system complexity while maintaining comprehensive guidance capabilities.

AI summary
A computer-assisted medical system includes a user device wearable by an operator. The user device includes a display device configured to present imagery overlaid in an environment of a manipulator assembly, and a sensor configured to detect one or more landmarks in the environment. The medical system includes a controller configured to execute instructions to perform operations The operations include receiving, from the sensor, position or orientation information for the one or more landmarks in the environment, and directing a manual movement of a portion of the manipulator assembly by causing the display device to present the imagery overlaid in the environment based on the received position or orientation information.
