Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual maneuvering is used to overcome obstacles, then the medical object can be moved past obstacles, but radiation exposure and tissue injury risk increase
Solution Approach 1:
The patent replaces manual mechanical maneuvering with an automated robotic system that uses sensors and control algorithms to navigate obstacles. The robotic device incorporates a mover device with actators that automatically adjust the medical object's position and orientation based on sensor feedback, eliminating the need for manual manipulation and associated radiation exposure.
Solution Approach 2:
The robotic system enables the medical object to navigate obstacles autonomously through sensor-based detection and automated response. The system independently identifies obstacles, determines appropriate movements, and executes navigation without requiring continuous manual intervention, thereby reducing radiation exposure while maintaining navigation capability.
2Object-affected harmful factors
If automated robotic movement is used, then radiation exposure is reduced, but device complexity increases
Solution Approach 1:
The robotic system is divided into modular functional components: a mover device for physical manipulation, sensor units for environmental detection, control algorithms for decision-making, and a medical object for treatment. This segmentation allows each component to be optimized independently and facilitates easier implementation and maintenance while achieving automated navigation with reduced radiation exposure.
Solution Approach 2:
The robotic device is designed as a multi-functional system that can perform various navigation tasks and adapt to different medical procedures. The same basic architecture with sensors, mover device, and control system can handle different medical objects and obstacle configurations, reducing the need for multiple specialized devices and justifying the increased complexity through versatile functionality.
3Measurement precision
If real-time sensor feedback is implemented, then navigation precision is improved, but system complexity and computational requirements increase
Solution Approach 1:
The system continuously monitors the medical object's position, orientation, and surrounding environment using sensor units, comparing real-time data against the planned trajectory. Based on this feedback, the control algorithm automatically adjusts the mover device to correct deviations and navigate obstacles, achieving high navigation precision through closed-loop control while managing system complexity through efficient feedback processing.

AI summary
A device for moving a medical object includes a mover device for robotically moving the medical object. At least a predefined section of the medical object is arranged in an examination subject in an operating state of the device. The device is configured to receive a control preset. The control preset specifies a first movement for the predefined section of the medical object. The mover device is configured to move the medical object along a first movement direction in accordance with the control preset. The device is further configured to identify a deviation between a movement state of the predefined section of the medical object and the first movement and to determine a correction preset in order to minimize the deviation. The mover device is further configured to move the medical object at least partially counter to the first movement direction in accordance with the correction preset.
