Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a robotic arm is used for remote operation, then precise remote guidance is achieved, but device complexity and cost increase significantly
Solution Approach 1:
The patent extracts the control function from a complex robotic arm system and implements it through a simple display device showing movement commands. The display device visually presents directional indicators that guide the operator's movements without requiring complex robotic actuation mechanisms, thereby reducing system complexity while maintaining guidance precision.
Solution Approach 2:
The patent creates a visual copy of the desired movement path through directional indicators on the display device. Instead of directly controlling a robotic arm, the system displays simplified visual representations (arrows, icons) that replicate the intended movement trajectory, allowing the operator to follow these visual copies and achieve precise remote guidance through manual operation.
2Measurement precision
If a robotic arm is used for remote operation, then precise remote guidance is achieved, but data rate requirements increase
Solution Approach 1:
The patent extracts the essential guidance information from complex robotic control signals and presents it through simplified visual indicators. By removing unnecessary control data and retaining only the essential directional guidance, the system achieves precise remote operation with minimal data transmission requirements, eliminating the need for high data rate connections.
3Ease of operation
If verbal instructions are used for remote guidance, then communication is simple, but precision and reliability decrease
Solution Approach 1:
The patent replaces the acoustic channel (verbal instructions) with a visual display system that presents directional guidance through static or dynamic visual indicators. This substitution eliminates the ambiguities of verbal communication while maintaining simplicity, as the visual display provides precise, unambiguous directional guidance that cannot be misinterpreted, thereby simultaneously achieving ease of operation and high precision.
4Measurement precision
If additional data lines are added for robotic control, then control precision is improved, but system cost and complexity increase
Solution Approach 1:
The patent extracts the control function from data-intensive robotic systems and implements it through visual guidance that requires minimal data transmission. By removing the need for high-bandwidth communication channels and complex control protocols, the system achieves precise control with existing infrastructure, eliminating the need for additional data lines while maintaining control precision.

AI summary
The system has an input device i.e. control patch, for entering commands by a user i.e. physician, with respect to movements of a spatial diagnostic apparatus (16) from the input device. A display device (14) i.e. LED, has a data link connected to the input device for displaying motion commands entered by the user. The display device is connected to the diagnostic apparatus in such a manner that the display device is not movable relative to the diagnostic apparatus. The input device has a slider for inputting a command for a translatory motion of the diagnostic apparatus. An independent claim is also included for a method for carrying-out a remote diagnosis.
